Thesis word count and format

Three months ago you considered whether you required a restriction to the access of your thesis, and you submitted your ‘Approval of Research Degree Thesis Title’ form. You’ve now finished writing up your thesis and it’s time to submit. We require your thesis to be presented and formatted in a certain way, so it’s important you read through the requirements below, before submitting your thesis. Find out more about thesis submission policy  (.pdf)

The completed thesis should be saved in PDF format. Once saved, please review the file to ensure all pages are displayed correctly.

Page layout

• Double line spacing should be used for everything except quotations, footnotes, captions to plates etc.
• It is desirable to leave 2.5cm margins at the top and bottom of the page.
• The best position for the page number is at the top right 1.3cm below the top edge.
• The fonts of Arial or Times New Roman should be used throughout the main body of the thesis, in the size of no less than 12 and no greater than 14

Illustrations (Graphs, diagrams, plates, computer printout etc.)

Illustrations embedded within the thesis should be formatted, numbered and titled accordingly:

a) Illustration upright - Caption at the bottom, Illustration number immediately above the

Illustration.

b) Illustration sideways - Caption at right-hand side with Illustration number above it.

Numbers for graphs, diagrams and maps are best located in the bottom right hand corner.

For further advice, please consult your supervisor.

Word counts

The following word counts are the maximum permitted for each level of award*:

What's excluded from the word count

*In all cases above, the word count includes quotations but excludes appendices, tables (including tables of contents), figures, abstract, references, acknowledgements, bibliography and footnotes (as long as the latter do not contain substantive argument). Please note these are word limits, not targets.

Specific requirements

For degrees which involve Practice as Research (PaR), no less than 50% of the research output should be the written thesis. The written thesis for PaR degrees may be comprised of a range of written elements including, but not limited to, a critical review, a portfolio, and/or a statement on theoretical discourse or methodology.

**In cases of practice-based PhD’s or MPhil’s these suggested word counts may be different. It is normally expected that the written component would comprise no less than 50% of the overall output.

Each copy of the thesis should contain a summary or abstract not exceeding 300 words.

As an example, see how the  layout of your title page (.pdf) should be.

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What’s a Good Word Count for a Thesis Statement?

Crafting a thesis statement is an essential skill for all students to develop if they want to write quality essays and earn high grades. Although most understand the basics of how to write a thesis statement , many students wonder how long it should be.

Everyone agrees it has to be “concise,” but exactly how concise? Is there a magic number of words you should be looking to reach (or avoid exceeding) in your word counter?

Unfortunately, the exact number of words can be tough to pinpoint. The range can be anywhere between 20-50 words depending on your topic.

Thankfully, there are some examples and hints to help you see if your thesis statement length is appropriate.

How Long is Too Long?

Compare these thesis statement examples :

• All students should have access to a free college education because society will benefit from having better-educated citizens to help guide our nation.
• I think that it would be a positive idea to have each and every student who wants to attend a college or university be able to do so at no cost to him or her because our whole nation would be better off if people were smart enough to make wise decisions to lead our country in a good direction.

When we enter these into our word counter , the first example is 24 words. The second? A whopping 60 words!

Unnecessary words have no place in a thesis statement, and number 2 has a lot of extra words that don't need to be there.

Bottom line: If you can say more using less, do it.

Use the Introductory Paragraph

You might be thinking: I have a lot I want to say about my main idea, but I don't think I can cram all of my thoughts into one clear and concise sentence .

This is a really common concern. But no need to worry. You can create a concise thesis statement and still add your supporting thoughts throughout the essay.

Remember, your thesis statement is just one sentence of your introduction. You can surround it with other details and information you want to share about your topic.

But this leads to more questions:

• How many sentences in a paragraph will make my essay most effective?
• How many words in a paragraph is an acceptable number?

While there is no exact number, you should be mindful of how wordy your paragraphs and sentences are . Every word should be purposeful and your ideas should be clear. Broad or vague statements are a no-no when it comes to making a strong claim.

So What is the Magic Number of Words?

You want to aim for the most clear and concise thesis statement you can make. If you have a more complex idea, naturally your word count will be higher than if you are expressing a more basic argument.

Like I mentioned above, the range can be anywhere between 20–50 words depending on the subject you're writing about.

No matter your topic, your goal should always be to be specific, accurate, and supportive of your claim. Always avoid unnecessary words and vague statements.

If you are successful in getting rid of the “fluff,” you should have all of the words you need to make your thesis statement count.

How to Write a Science Thesis/Dissertation

A thesis/dissertation is a long, high-level research paper written as the culmination of your academic course. Most university programs require that graduate and postgraduate students demonstrate their ability to perform original research at the thesis/dissertation level as a graduation requirement.

Not all theses/dissertations are structured the same way. In this article, we’ll specifically look at how to structure a thesis/dissertation in the sciences and examine what belongs in each section. Before you begin writing, it is essential to have a good understanding of how to structure your science thesis/dissertation and what elements you must include in it.

How are science theses/dissertations structured?

There isn’t a universal format for a science thesis/dissertation. Each university/institution has its own rules, and these rules can vary further by department and advisor. For this reason, you must start writing/drafting your thesis/dissertation by checking the rules and requirements of your university/institution.

Some universities mandate a minimum word count for a thesis/dissertation, while others provide a maximum. The number of words you are expected to write will also vary depending on the program/course you are a part of. A Master’s level thesis/dissertation can range, for example, from 15,000 to 45,000 words, while a PhD thesis/dissertation can be around 80,000 words.

While your university/institution may have its own specific requirements or guidelines, this article provides a general overview of how a typical thesis/dissertation in the sciences should be structured. For easier understanding, let’s break it up into two parts:

• Thesis body
• Supplemental information

The thesis body of your thesis/dissertation includes:

• Acknowledgements

Table of contents

Introduction/literature review, materials/methodology, discussion/conclusion, figure and tables, list of abbreviations.

Your thesis will conclude with the supplemental information section, which comprises:

Reference list

Your thesis may or may not include each and every one of these sections. Now, let’s examine the parts of a thesis/dissertation in greater detail.

The parts of a science thesis/dissertation: Getting started

Let’s begin by reviewing the sections of the thesis body, from the title page to the glossary. This part of your thesis/dissertation should ideally be written last, even though it comes at the beginning. That is because it is the easiest to put it togethe r once you have written the rest of your thesis/dissertation.

Your thesis/dissertation should have a clear title that sums up the content. In addition, the title page should include your name, the degree of your thesis/dissertation, your department, your advisor, and the month/year of submission. Your university/institution likely has its own format for what should be included in the title page, so make sure to check the relevant guidelines.

Acknowledgments

This section gives you the opportunity to say thanks to anyone who gave you support while you worked on your thesis/dissertation. Many people use this section to give credit to their advisor, editor, or even their parents. If you received any funding for your research or technical assistance, make sure to mention it here.

Your abstract should be a brief summary (generally around 300 words) of your thesis/dissertation. You can think of your abstract as a distillation of your thesis/dissertation as a whole. You need to summarize the scope and objectives, methods, and findings in this section.

 The table of contents is a directory of the various parts of your thesis/dissertation. It should include the headings and subheadings of each section along with the page numbers where those sections can be found.

 Think of this section as the table of contents for figures and tables in your thesis/dissertation. The titles of each figure/table and the page number where it can be found should be in this list.

This list is intended to identify specialized abbreviations used throughout your thesis/dissertation. This can include the names of organizations (WHO, CDC), acronyms (PFC), and so on. For a science thesis/dissertation, it is preferable also to include a note regarding any abbreviations for units of measurement and standard notations for chemical elements, formulae, and chemical abbreviations used.

In this section, you would define any terminology that your target audience may be unfamiliar with.

The parts of a science thesis/dissertation: Presenting your data

Following the glossary, the thesis body of a science thesis/dissertation begins with the introduction. The introduction section of a science thesis/dissertation often also includes the literature review. This is unlike most social science or humanities theses/dissertations, where the literature review commonly forms a separate chapter. The introduction section should begin by clearly stating the background and context for your research study, followed by your thesis question, objectives, hypothesis , and thesis statement . An example might be: 

“The connection between nicotine consumption and insulin resistance has long been established. However, there is no substantial body of research on how long insulin resistance is maintained after people quit smoking. In this study, we aim to measure levels of insulin resistance in otherwise healthy subjects following a total cessation of nicotine consumption. We hypothesize that insulin resistance will begin to decline rapidly within six months.”

 The introduction should be immediately followed by a review of earlier literature written on the thesis topic. In this section, you should also clearly identify where the literature connects to your study and how your research study fills a gap or bolsters previous studies. Fit your study within the puzzle of previous work and demonstrate the importance of your research.

In the methodology section of your thesis/dissertation, you must explain what you did and how you did it. If you used materials (for example, bacteria), make sure you clearly list each one. Live materials should be listed, including the specific strain and genus. You must explain your techniques, materials, and methods such that another researcher can replicate exactly what you have done.

In the results section, you will explain what happened. What were your findings? This section should be heavy on data and light on analysis. Usually, in-depth analysis and interpretation of your results will be covered in the discussion section of your thesis/dissertation. While you should present your results in full, any supplementary data that you don’t have room for can be included in an appendix. As a note, this section is often written in the past tense. While other portions of your thesis/dissertation may use past and present interchangeably depending on the topic at hand, the results section of a scientific paper focuses on what has already happened (in an experiment), which is why it is written this way.

In this part of your thesis/dissertation, you will discuss what your findings mean. Did they align with your hypothesis? If so, how? If not, what was different? If there were any exceptions, errors, or total lack of correlation found, do not try to hide it. Clearly discuss what it might mean, or if you aren’t sure, don’t be afraid to say so. In this section, you can also highlight potential practical applications for your research study, limitations of your study, directions for future studies, and once again highlight the importance of your study in the field. This section usually concludes with an overall summarization of whether your results support your hypothesis or not. For example:

“Our study found that 500 of our 600 subjects continued to exhibit high levels of insulin resistance three years or more after stopping nicotine use. This does not support our hypothesis that insulin resistance would begin to drop around six months after subjects stopped nicotine use. Further research is warranted into the mechanisms by which past nicotine use alters insulin resistance levels in former smokers.”

The reference list is an alphabetical or numerical list of sources you’ve used while researching and writing your thesis. The formatting of your reference list will be dependent on your university guidelines. Useful tools like citation generators can help you correctly format your references. Reference managers like EndNote or Mendeley are also helpful for compiling this list. Furthermore, a professional editor or proofreading service can ensure that each reference is correctly formatted.

This section can be very useful if you want to include materials that are relevant to the topic of your thesis/dissertation but that you were unable to include in the main text. Tables, large bodies of text, illustrations, forms used to collect data or perform studies, and other such materials can all be included in an appendix.

Critical steps for planning, drafting, and structuring a science thesis/dissertation

Writing your thesis/dissertation is a daunting and lengthy task. Here are some helpful tips to keep in mind when drafting your science thesis/dissertation:

• Choose a thesis topic that is of professional interest to you. You are going to spend a lot of time thinking, reading, and writing about your thesis topic. Many aspiring young researchers end up working in a field related to their thesis/dissertation . If you start researching or writing a proposal and then decide you aren’t into the topic, don’t be afraid to change directions!
• Plan your thesis timelines carefully. Is your topic realistic given the time and material constraints you have? Do you need to apply for external funding for your research study? Will that take additional time? Write a schedule and revisit/revise it often throughout your thesis/dissertation process.
• Don’t wait until the last minute to start writing! A thesis/dissertation isn’t like an undergraduate paper where you spend some time researching and then some time writing it. You will need to write your thesis/dissertation as you continue your research study. Write as you work in the lab. Write as you learn things and then revise. Ideally, by the time you have finished your actual research study, you will already have a substantive draft.
• Start writing the methodology section first. This is often the easiest because it is straightforward and you have already done quite a lot of the work while preparing your research study. The order in which you write your thesis/dissertation doesn’t matter too much—if you find yourself jumping between sections, that is perfectly normal.
• Keep a detailed list of your references using a reference manager or similar system, with tags so that you can easily identify the source of your information.

Final tips for writing and structuring a science thesis/dissertation

Writing a thesis/dissertation is a rewarding process. As a final tip for getting through this process successfully, don’t forget to leave sufficient time for editing and proofreading. Your thesis/dissertation will go through many drafts and revisions before it reaches its final form.

Engaging the services of a professional can go a long way in helping you produce a professional and high-quality document worthy of your research. In addition, there are many helpful tools like AI grammar checker tools available online for students and young researchers.

Managing Writing

At this point, you should be making some good progress towards the work that will ultimately become your actual thesis document, and you may be starting to get a little anxious to start actually WRITING something. You have been using your calendar to manage your time , your outline  to manage your content , and Evernote to manage your materials .

Now it is time to start to focus on your writing process. There are several things that we need to do to get prepared for this and make it a manageable process. Remember, the goal here is to find ways to break down a project that at first seems insurmountable into smaller pieces and a process that is doable — Mind like water.

Before we jump into writing, we need to do a bit of prep work. We are going to need to do some planning, tool set-up, and some goal setting.

Setting your Writing Goals

As I’ve stated previously, the goal of our system is to continually be breaking down the task of doing the thesis process in manageable chunks. When we are looking at other people’s finished theses and seeing 200 page documents, it is still too overwhelming. There is too much psychological friction to the idea of being able to do that much.

We are in luck though because there is yet another level to how formulaic the thesis is. While different sources vary by a few percentage points, all that I found, along with all the thesis documents I have personally inspected, seem to hover right around these marks.

• Introduction – 5%
• Background – 20%
• Methodology – 15%
• Results & Analysis – 45%
• Synthesis – 15%

I needed to put this into a more measurable goals so that I could track, and see my progress when it came to writing. So what I did was I found two theses from the recent past in the department and counted their words. I found one that seemed pretty short but accomplished the task, and one that was pretty long compared to most of the others. I downloaded the PDFs from the library’s database. I copied from the title of the first chapter to the last word of the last chapter and pasted that into two respective word-processor documents, then ran the word count function. This also helped control for differing amounts of images, formatting choices, etc… that just counting pages would not have.

What I found was that the Short Thesis was just shy of 17,000 words and the Long Thesis just crossed over the 47,000 word mark. This gave me a range to work within. Under-achievers (yet successful) write 17,000 words… over-achievers write 47,000 words.

Now it was a simple math game to get me going on some more concrete goals. I somewhat arbitrarily set 30,000 words as my total word goal for my first draft of my thesis. I figured that I have always been a bit of an over-achiever, I am a pretty good writer, but there is no reason to break the mold here. 30,000 words seemed like a length I could be proud of. You can set your mark where you want. You are the one that has to be happy with the outcome. I will use the 30,000 word goal for my examples though, as I already did this math and it was sitting in my Evernote account for easy reference.

With 30,000 words as my goal, the math game played out like this:

• Introduction: 1500 words – Easy peasy lemon squeesy! In 12pt double spaced Times New Roman, this is just a little over six pages. We have all written six pages before, sometimes even on topics we know very little about. You are going to know A LOT about your thesis topic.
• Background: 6,000 words – Just shy of 25 pages, spread between at least 2, maybe 3 chapters, certainly manageable.
• Methodology: 4500 words – 18 1/2 pages, a good chance that this will be one chapter, but it will predominantly be a rehashing of everything you will have prepared for your IRB Proposal. When it comes time to write, the first draft of this chapter will already be extremely close thanks to the IRB.
• Results & Analysis: 13,500 words – about 56 pages. I will give it to you. This one still seems pretty big, but remember, this will be once again spread out over probably 3 chapters. That is less than 19 pages per chapter. Reminder, we are talking double spaced pages too! Single spaced, this would only be less than 10 pages per chapter. That is a bit of a mind game, but 10 pages is once again… easy peasy!
• Synthesis (Discussion & Conclusions): 4500 words – 18 1/2 pages. I guarantee that by the time you get to this phase of writing you will know so much, have discovered so much, that your biggest challenge will be keeping your writing DOWN in this range. You will hit 4500 words and think to yourself “Oh Snap! I haven’t even touched on three of my key ideas yet.”

Word Count vs. Page Count

I have just been giving you page counts to help you visualize the word counts. I want to clarify this because most of us are not really accustomed to thinking in word counts, but I STRONGLY believe that word counts are a much better way to set your writing goals. Pages are malleable. You put a couple nice charts or figures in a chapter and your page count goes up automatically. You set your type in a different typeface, page count changes. You know this. You’ve done this. Your history prof wants a ten-page paper… but has not specified the font. You know she probably expects Times New Roman. You write and write and then you have nothing left. You look down and you’ve barely broke the 9 page mark. Select all, VERDANA… BAM! Ten pages. Done. But look at that word count. You wrote 2300 words! That is why we set writing goals in word counts and not page counts. Page counts mean nothing.

These word counts will become more important and more refined as your outline develops and when we get to the writing portion ahead. So do this math for your total word count goal and write it down somewhere. Ideally, you will create a new note for these goals in Evernote and put it in your zz.Admin notebook. It will be safe there and we will reference it again very shortly.

Writing Software

Now you need a tool to help you write. You could use a pencil or pen I suppose. If this is your preferred option… umm go for it and I apologize, because I am sure that this entire site has been a complete bore for you. I would not recommend pen or pencil as your primary writing tool.

Ten-to-one, you are going to want to use a word-processor program of some sort. A word processor is a computer application used for the production of any sort of printable material.

There are lots of options here. LOTS. The big three though tend to be:

• MS Word on Windows or Mac. You all know this one. You are probably currently planning on using this app, and I fully understand why you might be. Word has made itself the so to speak “Gold-Standard” of Word Processors. That stated, I hate MS Word. It is a ridiculously large, bloated application and because there are so many versions out there, when I USED word, I always ran into issues with compatibility. Your milage may vary, but I am going to tell you not to use it and I am sorry that you spent $140 on this application.
• Pages on Mac and iOS. This is my go to for shorter documents. If you are running Mac OS and only planning on a straight-forward piece of writing that is less than, lets say about 10 pages, it is great. It has all the features you need and very few of the ones you do not. I am a Mac fanboy though too, so there is that.
• Open Office is the big one on Linux, but also a cult following on Mac and Windows. I like its politics of being Open Source, but in my experience it can be a little buggy at times.

There are a lot of others out there and because I am really nerdy about these sorts of things I have used many at one point or another. Especially when you start bringing iOS into the mix, there are many more options to consider and I use other things for other purposes.  They all have their strengths and weaknesses. I am emphasizing how much I tinker with word processors and text editors only so that you believe me when I state that there is really only one application that I would recommend using for complex, really long-form writing like your thesis.

How long should be a Doctoral Dissertation or Thesis?

A doctoral dissertation or thesis should be of 50,000 to 80,000 words and should not exceed 1,00,000 words having around 150 to 230 pages. 

“One size can’t fit to all.”  

A fat person can’t fit into a lean person’s trouser, isn’t he?

The same is true for the most important academic essay as well, the PhD thesis or dissertation or we can say a doctoral dissertation.

The present article illustrates how long should be a PhD dissertation! the number of words, number of chapters and pages. We will also discuss what should be your thesis length and how you can decide it. But before that let’s understand the concept of a doctoral dissertation or thesis. 

The doctoral dissertation or thesis is almost the same kind of thing! Some universities prefer to say it as “dissertation” while others say it “a thesis” but ideally, as per the USA PhD structure, the dissertation is considered as a short essay and often applied to denote a thesis to award the master degree.

Notwithstanding, we can use either term to indicate a PhD essay.  Either a thesis or dissertation, any of it can be used. So don’t confuse yourself. 

The PhD dissertation is an academic essay, structured, formal and concise and precisely written. The whole thesis must be divided into specific chapters each one includes specific information. 

For example, the introduction chapter includes general information only while the review chapter must include literature and reviews of all related topics. 

The content of the dissertation may vary from chapter to chapter that we will discuss later on. Sections of every PhD dissertation have a definite content and length as well, and therefore the whole thesis has a definite length. 

The criteria to write a PhD dissertation (what to write and how to write) vary among universities, some prefer longer essays while some shorter. Let’s not confuse things and let directly into the topic,

How long should be a doctoral dissertation or thesis? 

The ideal length of the doctoral dissertation is between 50,000 to 80,000 (actually), however, should not exceed 1,00,000 words.

Do you know?  “A New Determination of Molecular Dimensions” is a thesis title of Albert Einstein which has only 17 pages .

The whole doctoral dissertation divides into sections like background (commonly an introduction), review, methods, results, discussion and conclusion. 

Besides, Acknowledgement, preface, abstract, index, list of images, list of tables and title page and other pages are there in the thesis but can’t be included in the core content of the doctoral dissertation. 

In accordance with the number of pages, a typical thesis has a minimum of 180 and a maximum of 300 pages with an average of 230 pages per dissertation and consider as the ideal length of the doctoral dissertation. 

However, here are some of the factors upon which the length of the thesis is decided. 

• The subject chosen
• The topic of the doctoral dissertation 
• University selected 

The length of the thesis varies among subjects as some need longer, in-depth explanation whilst some only contain equations or mathematical calculations. 

Usually, dissertations of humanities such as history, language and social science are long around 1,00,000 to 1,20,000 words. On the other side, the dissertation of STEM ( Science, Technology, Engineering and Mathematics) are shorter around 50,000 to 80,000 words. 

Here is the graph of the number of pages and length of the thesis in different subjects. 

Another factor is a topic chosen by the prospective student. The length of the doctoral dissertation also depends on a topic selected, independent of the subject. 

For example, some topics are shorter and “require to the point” explanation, topics of maths and physics are based on equations and calculations henceforth those theses ideally might be shorter than other topics. 

On the other side, a topic that includes not only scientific experiments but also physics or maths and social benefits are usually longer. The reason is that prospective students need to explain the science behind that and its importance for society as well. So it may be huge. 

Related article: 16 Proven Tips to Write a Thesis for PhD .

The style of writing, length and structure of dissertation may vary among universities. Universities have their own style and students have to write their thesis accordingly.

Do you know?  David Rector’s thesis entitled, “An unstable Adams Spectral Sequence” is the shortest thesis in the world having only 9 pages (as per the MIT library of thesis). 

Note that the quality of the doctoral dissertation isn’t associated with the length of it. Consequently, a longer thesis isn’t mean quality work whilst a shorter thesis isn’t mean poor work! 

Plenty of research data are available on the length of the doctoral dissertation and the number of pages but interestingly, conclude nothing! 

This means, research conduct on 1000 student show that the thesis should have 1,00,000 pages doesn’t infer that you have to write a dissertation of exactly having the same length.

Dr Eva Lantsoght had conducted a poll on Twitter on “what was the word count of your dissertation?” 

34% of students voted that their thesis is 80,000 to 1,20,000 words long while 21% of students voted to have a dissertation length of fewer than 40,000 words. However, the study is irrelevant as students aren’t categorized based their subjects. (but it’s just a Twitter Poll!). 

As we said, the number of pages or words may deviate among universities, for example, ideally Cambridge university allow 80,000 words in a typical dissertation, however, in the same university the criteria for biology PhD thesis is 60,000 (as per their official website information).

Note that special permission is needed when students exceeds more than the limit decided.

Similarly, Oxford university and Harvard university advised dissertation length of 1,00,000 and 100 to 300 pages, respectively.

No such data or studies define how long exactly a doctoral dissertation should be because as we said, it’s not a major criterion in any university. If you write a thesis in either fewer or more words, the university will never reject it or fail you, based on that. 

Irrespective of the length of the dissertation, it must justify the research work done by the prospective candidate. If the examiner thinks that the thesis is too long, they advise you to make it shorter and vice versa, no issue in that. 

The only thing matter is that the work should be worth award-winning. However, some universities are strict against the length of the doctoral dissertation. Students need prior permission if their thesis excess the length decided by the university. For example, at Cambridge University, the length of a doctorate dissertation is fixed for different subjects. When exceeded, one has to take permission prior to submit the thesis. 

Do you know?  Historian Joachim Schuhmacher had written the world’s longest thesis having 2,654 pages. 

Now let us discuss how the length of a doctorate dissertation is decided? 

The answer to this question gives you an idea of “how many words you have to write”. A single thesis page should have around 325 to 333 pages when using Times New Roman font and double spacing (as per the MLA and APA formate ). 

When you write 100 pages it comprises 33, 300 words so when we write 250 pages, it comprises around 83,250 words. 

It means one should have to write around 60,000 to 70,000 words (220 to 230) pages for getting a doctoral degree. Again, keep in mind, not the length, the quality of research work and writing precision decides the fate of a student. 

Importantly, the ideal length of what we are discussing here only comprises content, we haven’t included other important pages such as a preface, acknowledgment, title page or other related pages. Those are single pages and must be labeled in italic, not in numbers. 

Refer university’s official circular or terms and conditions before applying as well as submitting a thesis. Do not trust blindly what others are doing.

Conclusion: 

What is the conclusion of the present topic? You may wonder I will advise you on how long a doctoral dissertation will be. Right! Well, in that case, I strongly recommended to contact the university and ask to the PhD department regarding requirements.

Keep in mind quality of research matter more rather than the quantity of writing. Still, you need to write a doctoral dissertation longer enough to evaluate.

As stated in the  Student Registry PhD format requirements , a PhD thesis in the Department of Computer Science and Technology “is not to exceed [...] 60,000 words including tables and footnotes, but excluding appendices, bibliography, photographs and diagrams.”

Candidates abusing these rules mostly risk annoying their examiners. Of particular concern is the misconception that tables and equations do not count as words, while they actually take significantly longer to read than mere text. The words “photographs and diagrams” refer to entities that can be taken in with a single glance rather than a page of detailed equations. Tables, equations and the like are best counted as having the number of words that text occupying the same area would have. The safest way to justify being under the 60,000 word limit is to count the words on a page with most plain text, and divide 60,000 by that to give a page limit. Another way of getting an estimate of the effective word count is

If the main body of your thesis (from first page to last page before the bibliography) is 150 pages or more then you have probably exceeded the size limit – and your thesis risks summary rejection. Remember that it is not necessary to write 59,995 words; as noted in the regulations for Physics and Chemistry: “[the] Degree committee points out that some of the best dissertations extend to only half this length”.

Sometimes candidates would like a bigger word-count limit. This is often a sign they have done too much work; a good thesis selects from the work done rather than slavishly including every minor result. There are three reasons not to do too much work on a thesis: poverty after your funding expires, scoring black marks for the department by submitting four years after starting, and having to leave out research results from your thesis!

The Degree Committee for the Faculty of Computer Science and Technology agreed, at its meeting of July 2nd 2009, that the word limit will remain at 60,000 words and, furthermore, emphasized that should students exceed 175 pages, students and their supervisors will be asked to explain.

The Degree Committee for the Faculty of Computer Science and Technology agreed, at its meeting on 23 November 2021, that while the word limit will remain at 60,000 words, the Committee recognises some theses are interdisciplinary. An application for an extension to the word counts where there is a compelling case - such as an interdiscipinary thesis - will be considered. Students should apply for an extension to the thesis word count via CamSIS Change of Circumstances.

Can a social sciences doctoral thesis be just 65k words long? [closed]

I am nearing the end of writing up my doctoral thesis. I only have the discussion to write and the introduction and conclusion to tidy up. My word count is currently 55k. Even with going back and writing as much as I can in every chapter, I can't see it getting above 65K. I am a former copywriter and proof reader and I write in a succinct and direct way using as few words necessary in order to convey a point effectively. Surely I can't be expected to 'pad' or add waffle just to hit the 80k proscribed length?

• 21 What does your advisor say? –  user438383 Oct 7, 2023 at 16:11
• 7 Who proscribed the length? I have never heard of any length requirements. –  Anonymous Physicist Oct 7, 2023 at 16:20
• 21 "the 80k proscribed length" You mean prescribed. (Just pointing this out because you mention that are a former and therefore possibly also future copywriter and proof reader...) –  Adam Přenosil Oct 7, 2023 at 16:39
• 2 As everyone else has said, padding your writing is a terrible idea. However, you should have a literature review chapter. Is it as complete as you can make it? Also see Buffy's answer. –  Bob Brown Oct 7, 2023 at 20:39
• 3 @AdamPřenosil Unless it really is "proscribed" because 80k is far too long. –  Daniel Hatton Oct 7, 2023 at 20:48

A dissertation needs to establish some hypothesis (answer some question) and explain why it is or isn't true, giving the necessary arguments and dealing with counterarguments. If you can do that succinctly, but correctly, that should be enough. Not everyone will agree, of course.

Your advisor is the best guide here as are, potentially, other faculty members in your field. You may have to adhere to some arbitrary standard. But padding for the sake of quantity helps no one.

But, for a student, checking the boxes is often necessary. Talk to your advisor.

• 6 I'm not sure "A dissertation needs to establish some hypothesis and explain why it is or isn't true" is universally applicable in the social sciences. –  Daniel Hatton Oct 7, 2023 at 20:48
• I concur with @DanielHatton ... A dissertation should establish some hypothesis and explanatory ... might be more like it for Humanities and Social Sciences. Although, some social sciences can be as IMRAD as they can be! –  semmyk-research Oct 7, 2023 at 21:05
• 1 @DanielHatton, they may not use the same terminology as the social sciences, but I'd guess that in most cases there is a "question" to be addressed, with "evidence". Not so far away. A stretch for Humanities such as Literature, perhaps, but even then it would sometimes (maybe often) apply. I was just looking at the academic history of the crime/thriller author Robert B. Parker, for example. My daughter's philosophy dissertation certainly had a hypothesis. But the "evidence" is less likely to be statistical. But evidence is needed to advance scholarship. –  Buffy Oct 7, 2023 at 21:47
• 2 Social science research usually derives hypotheses from theory and tests these hypotheses using qualitative (e.g. interview material) or quantitative (e.g. survey data, official statistics) material applying common analysis methods, such as cluster analysis, correlation/regression analysis, etc. What often makes social science research "longer" is the extensive discussion of theoretical approaches used to derive a hypothesis and for example the description of data and operationalization. –  Leonie Oct 8, 2023 at 9:02
• 1 @DanielHatton, absolutely, but if it were a thesis based on grounded theory we would be talking about much more than 65k words. –  Leonie Oct 8, 2023 at 16:33

When I did my PhD (in philosophy) many years ago, my supervisor advised me to go close to the maximum permitted number of words. His reasoning was that this would make it easier to defend the thesis at the viva since a question on the lines of "Why didn't you include X?" could (if no other justification was available) always be answered by "I was already at the word limit".

As a slightly separate point, he also advised that a good thesis usually resulted from writing too much and then, after critically reviewing the draft, cutting out some relatively lower quality or less relevant sections to reduce the word count to the permitted level.

As others have already pointed out, there usually is no minimum word count for a dissertation. The length of your dissertation is defined by the question you ask and the way you answer it. If your work is based on qualitative rather than quantitative analysis, your dissertation will probably be longer in text, also because you'll have no or less figures and tables.

• What you should do is check with your supervisor(s).

Things you can do to ease your mind:

• Check other former PhD candidates dissertations from your department or even from the same supervisor - how much did they write?
• I would consider checking how many papers you would have needed if you had done a paper based (cumulative) dissertation and multiply this by 8k-10k which is a normal word count for social science papers. Then add around one paper length for introduction and analysis strategy, one paper length for theoretical framework and literature review, and one paper length for discussion and summary.

Remember that your dissertation needs to answer a question. Do your hypotheses capture all relevant aspects of the question? Is your question comprehensively answered? Also consider that language plays a role here, as in some languages there is one word for something which has to be described in many words in others.

• 1 I definitely agree with the first point, my supervisor specifically asked me to read over the dissertation of his recent graduates. He also strongly recommend that I try and publish a journal or good conference paper for each chapter along with the literature review - the argument was it's very hard for examiners to reject something that's based of peer reviewed publications. –  David Waterworth Oct 9, 2023 at 3:02

The 80-100K words limit for a PhD thesis seems to be a conventional standard in the academia, because I received the same advice regarding word limit from my university that is located in another continent. From my personal experience, one can satisfy the word requirement with adequate and appropriate expansion of themes that are well critiqued and comprehensively articulated.

Have a second look at your work once more with a neutral and open mind to enable you locate which new themes to add and the ones to expand. A further critical look at the research topic, questions, objectives, hypothesis if any, and the theory underpinning the research will give you clues.

This task is impossible if you have already convinced yourself that there is nothing more you can do because you have done your best. Good luck to you.

Thesis word count

I have read that the maximum number of words for a thesis is 100,000. How does this breakdown in terms of the number of words per section and is there a minimum number of words? Cheers in advance Stephen

Ideally each chapter should be around 8,000 - 10,000 words. Though, it is not unusual to have chapters with 15,000. Longer chapters are harder to structure. If your chapter is longer than that try breaking it into two diffrent chapters. I havemnt heard of a minimum length, in physics and mathematics thesis could have 20,000 - 30,000 words and be less than a hundred pages. It depends on your area, try getting a few thesis of your area from your library (or just look online, there are some available), and see what is the usual length. At the end the minimum length is what has to be in the thesis, enough words to demonstrate that you made a contribution to knowledge, and to be a work that can be published. Good luck!

Guidelines for thesis length, including maximum and minimum lengths, vary by university and department/discipline. You should ask your prospective supervisor(s) about this, because the same subject at different universities can have different rules, and different subjects within the same university can be radically different. In my department the minimum length is 80K and maximum 100K. I'm actually going to come in under this minimum length, but have been advised that it will be ok, though I'm taking steps to make it look better, adding appropriate appendices, though they don't count for total length.

Thanks for that athos78 and BilboBaggins, I have just been trying to gauge how much effort I will need to put in!!

T.S. Eliot said "If I had more time, I would have written a shorter letter", and I think the same applies to a thesis. A lot of words doesn't necessarily mean a lot of content. A concise writer aims to communicate information with the least amount of words: as Professor Strunk says, "Rule #17: Omit Needless Words". I have a 130 page science thesis here that is just outstanding--a pleasure to read. Next to it is a 250+ page thesis which has less data, but is obviously longer, largely because the writing is not as concise--not a pleasure to read. Writing mostly in the passive instead of the active voice will also make a thesis much longer than it need be. Also, students who are insecure about whether they have done enough work tend to write excessively long theses (IMHO). Two of the least productive students in our group have written 350+ page theses (70,000+ words) yet don't have enough work in there to publish a single paper. Most science theses are about half that length (35,000 - 40,000). The most impressive thesis I've seen was European (from Sweden I think) and extremely thin. I thought my supervisor was kidding when he brought it out into the lab and announced its brilliance. When we looked inside, it pretty much consisted of a TOC then five chapters, each one a 1st author paper. Don't get caught up in thesis length or word count. The goal is to say everything you need to with the least amount of words.

How many people have minimum word limits for their thesis?

I am based in the UK and am just in the process of writing my thesis (a very slow process) and have been informed that there is a minimum word limit of 85,000 words. I have spoken to friends at other universities, and none of them have stipulations on the length of their thesis.

I was wondering how common this is? For what it's worth, I am studying chemistry

How long is a PhD dissertation? [Data by field]

The final piece of the PhD journey is the PhD dissertation. It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions.

A PhD can be anywhere from 50 pages to over 450 pages long. This equates to between about 20,000 words to 100,000 words. Most PhD theses are between 60,000 and 80,000 words long excluding contents, citations and references.

A PhD thesis contains different sections including an introduction, methods, results and discussion, conclusions, further work, and references. Each one of these different sections will vary in length depending on the field of study and your particular topic.

Ultimately, a PhD dissertation should contain as many pages and words as it takes to communicate the results of your multi-year investigation.

It is very rewarding to see your thesis come together as you are writing day after day. When I was writing my PhD dissertation I wrote the sections separately and my heart filled with joy when I finally put them all together and compile them into a single PDF document.

Counting the pages should not be the way to determine a PhD dissertation’s value but it certainly helps when your thesis is starting to look substantial in thickness.

How many pages should a PhD dissertation be?

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field. It has been created by Marcus Beck from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a PhD in your field.

Can a PhD dissertation be too long?

A PhD thesis should contain enough evidence and discussion to report on the most significant findings of your PhD research.

A PhD dissertation should not contain everything that you have done during your PhD. It should only include the data and information required to convince your PhD examining body that wraps up and tells the full story of particular lines of investigation.

Including random results, thoughts, or superfluous explanation can result in a dissertation that is unfocused. I have heard of music PhD is being described as too verbose and physical sciences PhD dissertations as being unfocused.

Therefore, a PhD thesis can be too long if the information it contains does not form a full and cohesive story.

One of my colleagues during their PhD removed an entire chapter from the thesis after writing it as the supervisor said that it needed more experiments to be a full story. They did not want to spend the next six months gathering the data and simply removed the chapter altogether.

How short can PhD dissertation be?

The shortest PhD dissertations are typically found in mathematics.

George Bernard Danzig was an American mathematical scientist who made contributions to industrial engineering and many other mathematical-related fields. An interesting miscommunication led to 1 of the shortest PhD theses ever.

In 1939 his professor wrote two problems on the blackboard and Danzig thought they were homeless assignments. He stated that they were harder than usual but handed in solutions to the surprise of the professor.

They were, in fact, open mathematical problems in statistics.

His professor said to bind the solution to the two problems together and submit them as his thesis – the total thesis length = 14 pages.

Obviously, most PhD theses and dissertations will be so much longer than that!

My PhD dissertation was 256 pages long. It was full of schematics, diagrams, and tables to demonstrate and communicate my findings.

I would say that most people’s PhD thesis experience will be closer to mine than Prof George Bernard Danzig’s.

Why PhD dissertations are typically so long

PhD dissertations are often over 200 pages long.

One of the primary reasons they are so long is that it is a single document that summarises many years of hard work. Also, summarising the research field to date and making sure that all of your references and citations are included so you avoid plagiarism will bolster the word count of the thesis dramatically.

Here are all of the reasons PhD dissertations tend to be so long.

Many years of work

PhD theses or dissertations contain many years of research and analysis.

In many of my YouTube videos I recommend that a PhD student work towards their PhD thesis by doing at least three hours of focused work every work day.

This amount of work quickly adds up.

Of course, not every bit of work makes it into the PhD dissertation but a lot of it does. It can be difficult to work out what to include or leave out of your thesis.

As a PhD student, I perfected the art of turning one experiment into many different types of grafts and schematics to fully explore the limits of my data. The graphs can take up a lot of space in your PhD thesis and, therefore, bolster the page count significantly.

In depth literature review

One of the most substantial parts of a PhD dissertation is the literature review.

The literature review can take up a huge portion of the early part of your PhD dissertation depending on the amount of data and publications in your field.

Writing an in-depth literature review requires just as much meticulous data analysis and searching as the central part of your dissertation.

Figures and schematics

Some fields end up producing a lot of figures and schematics.

My thesis had many full-page figures of atomic force microscopy experiments with much more explanation on subsequent pages.

As they say, a picture paints a thousand words and a dissertation can really benefit from having many schematics to highlight the important aspects of your findings.

References and citations

The recommended PhD dissertation word count from an institution or university does not include citations, references, or other thesis parts such as summary of abbreviations, table of figures, et cetera.

However, these components of your dissertation can take up many pages and add to the overall thickness of your PhD dissertation.

University formatting rules

University formatting rules will also dictate how you many pages your words take up.

I often get roasted on my YouTube channel for having doublespaced lines and wide margins. Unfortunately, this layout was dictated by my university before printing.

PhD dissertations often end up going into long-term storage and therefore, need to adhere to archival and standardised formatting rules.

Deep in the depths of the University of Newcastle, there is a copy of my thesis on a shelf. The formatting and binding rules mean that my thesis looks like everyone else’s.

Universities will often have their own requirements for PhD dissertation cover colour, quality, and type of paper. Even the quality of the paper can change the thickness of the PhD dissertation significantly.

PhD by publication

It is becoming increasingly common to submit a number of peer-reviewed papers bound together with supplementary information in between instead of a PhD dissertation.

The benefits of this to the researcher and university are:

• More early career peer-reviewed journals for career advancement
• an easier review process – they have already been peer-reviewed
• an early focus on publishing means better research outcomes for the researcher, supervisor, and Department.
• No mad rush at the end to finish a thesis
• continually writing peer-reviewed papers throughout your PhD helps with timely analysis and communication of results

Even though this option has been available to PhD students for a number of years, I have only known a handful of students actually submit their PhD via publication.

Nonetheless, having this option will suit some research fields better than others and lead to a more productive PhD.

Wrapping up

This article has been through everything you need to know about the length of a PhD dissertation and the common lengths of PhD dissertations for various fields.

Ultimately, there is no predefined length of a PhD.

A PhD thesis is as long as it needs to be to convince your examiners that you have contributed significantly enough to an academic field to be awarded the title of Dr of philosophy.

Mathematical and analytical theses tend to be shorter and can be as short as 50 pages (with one of the shortest being only 14 pages long). At the other end of the spectrum, PhD students in anthropology and history tend to produce the longest dissertations.

How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

When you’ve finished writing and revising your literature review, don’t forget to proofread thoroughly before submitting. Not a language expert? Check out Scribbr’s professional proofreading services !

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Numbers in your thesis: Should you use words or numerals?

Even experienced writers find it tricky to decide how to handle numbers within the body of their thesis. To make matters worse, many style guides use very different formats. What is a student to do? This article provides tips that will help you handle this issue within your writing. These tips are based on the APA guidelines related to numbers.

The basic rules

Numbers can be written either as words (e.g., one hundred) or numerals (e.g., 100). The basic rule is to use words for numbers from zero through nine, and then numbers from 10 onwards. This is true for both cardinal numbers (e.g., two, 11) and ordinal numbers (e.g., second, 11 th ). However, there are some exceptions:

• Use numerals for numbers from zero to nine that are followed by a precise unit of measurement or grouped together with a number that is ≥ 10.

• Use words for any number that is used to start a sentence, with the exception of years.

• Use words for common fractions and set expressions.

Writing percentages

With percentages, the standard is to use numerals and “%” (not “percent”).

The main exception is if you are using a percentage to begin a sentence. In this case, use words to express the entire percentage.

Reporting results that include numbers

If your thesis includes quantitative research, you probably have data to report. Statistics, mathematical functions, ratios, and percentages are all written using numerals. This is true regardless if they are included within a table or as part of the actual text. Keep the following guidelines in mind:

• Report most statistics to two decimal places (such as  M  = 5.44).
• Report statistics that could never exceed 1.0 to three decimal places (such as  p  < .001).
• Report percentages and degrees of freedom as whole numbers (such as 73%).
• Italicize values that are not Greek letters (such as  M ,  SD ,  p , and  F ).
• Include spaces before and after =, >, and <.

Writing numbers that are accompanied by measurements

If a number comes immediately before a unit of measurement, use numerals.

Also use numerals for precise ages, times, dates, scores, points on a scale, and amounts of money.

Writing long numbers

Longer numbers follow specific rules:

• Use a period to indicate a decimal point.
• Starting with 1,000, use commas to separate every three digits.
• Starting with a million, use a combination of numerals and words.

Consistency may not be obvious

One of the main reasons why writing numbers is complicated is that consistently applying the rules may lead to a text that actually seems very  in consistent. Consider the following paragraphs:

These texts may look awkward because so many different number formats have been used, but don’t be deceived – the above guidelines have all been followed.

If you are not required to strictly follow a particular style (such as APA), you may have some flexibility to modify the guidelines presented in this article. Just be sure to apply any modifications you make throughout your entire document.

Word limits and requirements of your Degree Committee

Candidates should write as concisely as is possible, with clear and adequate exposition. Each Degree Committee has prescribed the limits of length and stylistic requirements as given below. On submission of the thesis you must include a statement of length confirming that it does not exceed the word limit for your Degree Committee.

These limits and requirements are strictly observed by the Postgraduate Committee and the Degree Committees and, unless approval to exceed the prescribed limit has been obtained beforehand (see: Extending the Word Limit below), a thesis that exceeds the limit may not be examined until its length complies with the prescribed limit.

Extending the Word Limit

Thesis word limits are set by Degree Committees. If candidates need to increase their word limits they will need to apply for permission.

Information on how to apply (via self-service account) is available on the ‘ Applying for a change in your student status’  page. If following your viva, you are required to make corrections to your thesis which will mean you need to increase your word-limit, you need to apply for permission in the same way.

Requirements of the Degree Committees

Archaeology and anthropology, architecture and history of art, asian and middle eastern studies, business and management, clinical medicine and clinical veterinary medicine, computer laboratory, earth sciences and geography, scott polar institute, engineering, history and philosophy of science, land economy, mathematics, modern and medieval languages and linguistics, physics and chemistry, politics and international studies, archaeology and social anthropology.

The thesis is not to exceed 80,000 words (approx. 350 pages) for the PhD degree and 60,000 words for the MSc or MLitt degree. These limits include all text, figures, tables and photographs, but exclude the bibliography, cited references and appendices. More detailed specifications should be obtained from the Division concerned. Permission to exceed these limits will be granted only after a special application to the Degree Committee. The application must explain in detail the reasons why an extension is being sought and the nature of the additional material, and must be supported by a reasoned case from the supervisor containing a recommendation that a candidate should be allowed to exceed the word limit by a specified number of words. Such permission will be granted only under exceptional circumstances. If candidates need to apply for permission to exceed the word limit, they should do so in good time before the date on which a candidate proposes to submit the thesis, by application made to the Graduate Committee.

Biological Anthropology:

Students may choose between two alternative thesis formats for their work:

either in the form of a thesis of not more than 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The limits include all text, in-text citations, figures, tables, captions and footnotes but exclude bibliography and appendices; or

in the form of a collection of at least three research articles for the PhD degree and two research articles for the MSc or MLitt degree, formatted as an integrated piece of research, with a table of contents, one or more chapters that outline the scope and provide an in-depth review of the subject of study, a concluding chapter discussing the findings and contribution to the field, and a consolidated bibliography. The articles may be in preparation, submitted for publication or already published, and the combined work should not exceed 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The word limits include all text, in-text citations, figures, tables, captions, and footnotes but exclude bibliography and appendices containing supplementary information associated with the articles. More information on the inclusion of material published, in press or in preparation in a PhD thesis may be found in the Department’s PhD submission guidelines.

Architecture:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MSc or MLitt degree. Footnotes, references and text within tables are to be counted within the word-limit, but captions, appendices and bibliographies are excluded. Appendices should be confined to such items as catalogues, original texts, translations of texts, transcriptions of interview, or tables.

History of Art:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MLitt degree. To include: footnotes, table of contents and list of illustrations, but excluding acknowledgements and the bibliography. Appendices (of no determined word length) may be permitted subject to the approval of the candidate's Supervisor (in consultation with the Degree Committee); for example, where a catalogue of works or the transcription of extensive primary source material is germane to the work. Permission to include such appendices must be requested from the candidate's Supervisor well in advance of the submission of the final thesis. NB: Permission for extensions to the word limit for most other purposes is likely to be refused.

The thesis is for the PhD degree not to exceed 80,000 words exclusive of footnotes, appendices and bibliography but subject to an overall word limit of 100,000 words exclusive of bibliography. For the MLitt degree not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography and appendices.

The thesis for the PhD is not to exceed 60,000 words in length (80,000 by special permission), exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

The thesis for the MPhil in Biological Science is not to exceed 20,000 words in length, exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

For the PhD Degree the thesis is not to exceed 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices. It is normally expected to exceed 40,000 words unless prior permission is obtained from the Degree Committee. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size. The Degree Committee do not consider applications to extend this word limit.

For the Doctor of Business (BusD) the thesis will be approximately 200 pages (a maximum length of 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices).

For the MSc Degree the thesis is not to exceed 40,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices.

The thesis is not to exceed 80,000 words including footnotes, references, and appendices but excluding bibliography; a page of statistics shall be regarded as the equivalent of 150 words. Only under exceptional circumstances will permission be granted to exceed this limit. Candidates must submit with the thesis a signed statement giving the length of the thesis.

For the PhD degree, not to exceed 60,000 words (or 80,000 by special permission of the Degree Committee), and for the MSc degree, not to exceed 40,000 words. These limits exclude figures, photographs, tables, appendices and bibliography. Lines to be double or one-and-a-half spaced; pages to be double or single sided.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes and equations, but excluding appendices, bibliography, photographs and diagrams. Any thesis which without prior permission of the Degree Committee exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words for the PhD degree and the MLitt degree, including footnotes, references and appendices but excluding bibliography. Candidates must submit with the thesis a signed statement giving the length of the thesis. Only under exceptional circumstances will permission be granted to exceed this limit for the inclusion of an appendix of a substantial quantity of text which is necessary for the understanding of the thesis (e.g. texts in translation, transcription of extensive primary source material). Permission must be sought at least three months before submission of the thesis and be supported by a letter from the supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

The thesis is not to exceed, without the prior permission of the Degree Committee, 80,000 words for the PhD degree and 60,000 words for the MSc or MLitt degree, including the summary/abstract.  The table of contents, photographs, diagrams, figure captions, appendices, bibliography and acknowledgements to not count towards the word limit. Footnotes are not included in the word limit where they are a necessary part of the referencing system used.

Earth Sciences:

The thesis is not to exceed, without the prior permission of the Degree Committee, 275 numbered pages of which not more than 225 pages are text, appendices, illustrations and bibliography. A page of text is A4 one-and-a-half-spaced normal size type. The additional 50 pages may comprise tables of data and/or computer programmes reduced in size.

If a candidate's work falls within the social sciences, candidates are expected to observe the limit described in the Department of Geography above; if, however, a candidate's work falls within the natural sciences, a candidate should observe the limit described in the Department of Earth Sciences.

Applications for the limit of length of the thesis to be exceeded must be early — certainly no later than the time when the application for the appointment of examiners and the approval of the title of the thesis is made. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit of length will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes, bibliography and appendices. The Degree Committee points out that some of the best thesis extend to only half this length. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size.

The thesis is not to exceed 80,000 words for the PhD and EdD degrees and 60,000 words for the MSc and MLitt degrees, in all cases excluding appendices, footnotes, reference list or bibliography. Only in the most exceptional circumstances will permission be given to exceed the stated limits. In such cases, you must make an application to the Degree Committee as early as possible -and no later than three months before it is proposed to submit the thesis, having regard to the dates of the Degree Committee meetings. Your application should (a) explain in detail the reasons why you are seeking the extension and (b) be accompanied by a full supporting statement from your supervisor showing that the extension is absolutely necessary in the interests of the total presentation of the subject.

For the PhD degree, not to exceed, without prior permission of the Degree Committee, 65,000 words, including appendices, footnotes, tables and equations not to contain more than 150 figures, but excluding the bibliography. A candidate must submit with their thesis a statement signed by the candidate themself giving the length of the thesis and the number of figures. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words or go below 60,000 words for the PhD degree and not to exceed 60,000 words or go below 45,000 words for the MLitt degree, both including all notes and appendices but excluding the bibliography. A candidate must add to the preface of the thesis the following signed statement: 'The thesis does not exceed the regulation length, including footnotes, references and appendices but excluding the bibliography.'

In exceptional cases (when, for example, a candidate's thesis largely consists of an edition of a text) the Degree Committee may grant permission to exceed these limits but in such instances (a) a candidate must apply to exceed the length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be supported by a letter from a candidate's supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement of the Degree Committee for the Faculty of English that thesis must conform to either the MHRA Style Book or the MLA Handbook for the Writers of Research papers, available from major bookshops. There is one proviso, however, to the use of these manuals: the Faculty does not normally recommend that students use the author/date form of citation and recommends that footnotes rather than endnotes be used. Bibliographies and references in thesis presented by candidates in ASNaC should conform with either of the above or to the practice specified in Cambridge Studies in Anglo-Saxon England.

Thesis presented by candidates in the Research Centre for English and Applied Linguistics must follow as closely as possible the printed style of the journal Applied Linguistics and referencing and spelling conventions should be consistent.

A signed declaration of the style-sheet used (and the edition, if relevant) must be made in the preliminary pages of the thesis.

PhD theses MUST NOT exceed 80,000 words, and will normally be near that length.

A minimum word length exists for PhD theses: 70,000 words (50,000 for MLitt theses)

The word limit includes appendices and the contents page but excludes the abstract, acknowledgments, footnotes, references, notes on transliteration, bibliography, abbreviations and glossary.  The Contents Page should be included in the word limit. Statistical tables should be counted as 150 words per table. Maps, illustrations and other pictorial images count as 0 words. Graphs, if they are the only representation of the data being presented, are to be counted as 150 words. However, if graphs are used as an illustration of statistical data that is also presented elsewhere within the thesis (as a table for instance), then the graphs count as 0 words.

Only under exceptional circumstances will permission be granted to exceed this limit. Applications for permission are made via CamSIS self-service pages. Applications must be made at least four months before the thesis is bound. Exceptions are granted when a compelling intellectual case is made.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, in all cases including footnotes and appendices but excluding bibliography. Permission to submit a thesis falling outside these limits, or to submit an appendix which does not count towards the word limit, must be obtained in advance from the Degree Committee.

The thesis is not to exceed 80,000 for the PhD degree and 60,000 words for the MSc or MLitt degree, both including footnotes, references and appendices but excluding bibliographies. One A4 page consisting largely of statistics, symbols or figures shall be regarded as the equivalent of 250 words. A candidate must add to the preface of their thesis the following signed statement: 'This thesis does not exceed the regulation length, including footnotes, references and appendices.'

For the PhD degree the thesis is not to exceed 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

Criminology:

For the PhD degree submission of a thesis between 55,000 and 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

There is no standard format for the thesis in Mathematics.  Candidates should discuss the format appropriate to their topic with their supervisor.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, including footnotes and appendices but excluding the abstract, any acknowledgements, contents page(s), abbreviations, notes on transliteration, figures, tables and bibliography. Brief labels accompanying illustrations, figures and tables are also excluded from the word count. The Degree Committee point out that some very successful doctoral theses have been submitted which extend to no more than three-quarters of the maximum permitted length.

In linguistics, where examples are cited in a language other than Modern English, only the examples themselves will be taken into account for the purposes of the word limit. Any English translations and associated linguistic glosses will be excluded from the word count.

In theses written under the aegis of any of the language sections, all sources in the language(s) of the primary area(s) of research of the thesis will normally be in the original language. An English translation should be provided only where reading the original language is likely to fall outside the expertise of the examiners. Where such an English translation is given it will not be included in the word count. In fields where the normal practice is to quote in English in the main text, candidates should follow that practice. If the original text needs to be supplied, it should be placed in a footnote. These fields include, but are not limited to, general linguistics and film and screen studies.

Since appendices are included in the word limit, in some fields it may be necessary to apply to exceed the limit in order to include primary data or other materials which should be available to the examiners. Only under the most exceptional circumstances will permission be granted to exceed the limit in other cases. In all cases (a) a candidate must apply to exceed the prescribed maximum length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be accompanied by a full supporting statement from the candidate's supervisor showing that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement within all language sections of MMLL, and also for Film, that dissertations must conform with the advice concerning abbreviations, quotations, footnotes, references etc published in the Style Book of the Modern Humanities Research Association (Notes for Authors and Editors). For linguistics, dissertations must conform with one of the widely accepted style formats in their field of research, for example the style format of the Journal of Linguistics (Linguistic Association of Great Britain), or of Language Linguistic Society of America) or the APA format (American Psychology Association). If in doubt, linguistics students should discuss this with their supervisor and the PhD Coordinator.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, both excluding notes, appendices, and bibliographies, musical transcriptions and examples, unless a candidate make a special case for greater length to the satisfaction of the Degree Committee. Candidates whose work is practice-based may include as part of the doctoral submission either a portfolio of substantial musical compositions, or one or more recordings of their own musical performance(s).

PhD (MLitt) theses in Philosophy must not be more than 80,000 (60,000) words, including appendices and footnotes but excluding bibliography.

Appendices are relevant to the material contained within the thesis but do not form part of the connected argument. Specifically, they may include derivations, code and spectra, as well as experimental information (compound name, structure, method of formation and data) for non-key molecules made during the PhD studies.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted prior to and including October 2017.

A PhD thesis must not exceed 80,000 words, and will normally be near that length. The word limit includes appendices but excludes footnotes, references and bibliography. Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis.
