When should i compare and contrast, making effective comparisons, comparing and contrasting as a brainstorming tool, structuring your comparisons, other interesting articles, frequently asked questions about comparing and contrasting.

Many assignments will invite you to make comparisons quite explicitly, as in these prompts.

  • Compare the treatment of the theme of beauty in the poetry of William Wordsworth and John Keats.
  • Compare and contrast in-class and distance learning. What are the advantages and disadvantages of each approach?

Some other prompts may not directly ask you to compare and contrast, but present you with a topic where comparing and contrasting could be a good approach.

One way to approach this essay might be to contrast the situation before the Great Depression with the situation during it, to highlight how large a difference it made.

Comparing and contrasting is also used in all kinds of academic contexts where it’s not explicitly prompted. For example, a literature review involves comparing and contrasting different studies on your topic, and an argumentative essay may involve weighing up the pros and cons of different arguments.

As the name suggests, comparing and contrasting is about identifying both similarities and differences. You might focus on contrasting quite different subjects or comparing subjects with a lot in common—but there must be some grounds for comparison in the first place.

For example, you might contrast French society before and after the French Revolution; you’d likely find many differences, but there would be a valid basis for comparison. However, if you contrasted pre-revolutionary France with Han-dynasty China, your reader might wonder why you chose to compare these two societies.

This is why it’s important to clarify the point of your comparisons by writing a focused thesis statement . Every element of an essay should serve your central argument in some way. Consider what you’re trying to accomplish with any comparisons you make, and be sure to make this clear to the reader.

Comparing and contrasting can be a useful tool to help organize your thoughts before you begin writing any type of academic text. You might use it to compare different theories and approaches you’ve encountered in your preliminary research, for example.

Let’s say your research involves the competing psychological approaches of behaviorism and cognitive psychology. You might make a table to summarize the key differences between them.

Behaviorism Cognitive psychology
Dominant from the 1920s to the 1950s Rose to prominence in the 1960s
Mental processes cannot be empirically studied Mental processes as focus of study
Focuses on how thinking is affected by conditioning and environment Focuses on the cognitive processes themselves

Or say you’re writing about the major global conflicts of the twentieth century. You might visualize the key similarities and differences in a Venn diagram.

A Venn diagram showing the similarities and differences between World War I, World War II, and the Cold War.

These visualizations wouldn’t make it into your actual writing, so they don’t have to be very formal in terms of phrasing or presentation. The point of comparing and contrasting at this stage is to help you organize and shape your ideas to aid you in structuring your arguments.

When comparing and contrasting in an essay, there are two main ways to structure your comparisons: the alternating method and the block method.

The alternating method

In the alternating method, you structure your text according to what aspect you’re comparing. You cover both your subjects side by side in terms of a specific point of comparison. Your text is structured like this:

Mouse over the example paragraph below to see how this approach works.

One challenge teachers face is identifying and assisting students who are struggling without disrupting the rest of the class. In a traditional classroom environment, the teacher can easily identify when a student is struggling based on their demeanor in class or simply by regularly checking on students during exercises. They can then offer assistance quietly during the exercise or discuss it further after class. Meanwhile, in a Zoom-based class, the lack of physical presence makes it more difficult to pay attention to individual students’ responses and notice frustrations, and there is less flexibility to speak with students privately to offer assistance. In this case, therefore, the traditional classroom environment holds the advantage, although it appears likely that aiding students in a virtual classroom environment will become easier as the technology, and teachers’ familiarity with it, improves.

The block method

In the block method, you cover each of the overall subjects you’re comparing in a block. You say everything you have to say about your first subject, then discuss your second subject, making comparisons and contrasts back to the things you’ve already said about the first. Your text is structured like this:

  • Point of comparison A
  • Point of comparison B

The most commonly cited advantage of distance learning is the flexibility and accessibility it offers. Rather than being required to travel to a specific location every week (and to live near enough to feasibly do so), students can participate from anywhere with an internet connection. This allows not only for a wider geographical spread of students but for the possibility of studying while travelling. However, distance learning presents its own accessibility challenges; not all students have a stable internet connection and a computer or other device with which to participate in online classes, and less technologically literate students and teachers may struggle with the technical aspects of class participation. Furthermore, discomfort and distractions can hinder an individual student’s ability to engage with the class from home, creating divergent learning experiences for different students. Distance learning, then, seems to improve accessibility in some ways while representing a step backwards in others.

Note that these two methods can be combined; these two example paragraphs could both be part of the same essay, but it’s wise to use an essay outline to plan out which approach you’re taking in each paragraph.

Some essay prompts include the keywords “compare” and/or “contrast.” In these cases, an essay structured around comparing and contrasting is the appropriate response.

Comparing and contrasting is also a useful approach in all kinds of academic writing : You might compare different studies in a literature review , weigh up different arguments in an argumentative essay , or consider different theoretical approaches in a theoretical framework .

Your subjects might be very different or quite similar, but it’s important that there be meaningful grounds for comparison . You can probably describe many differences between a cat and a bicycle, but there isn’t really any connection between them to justify the comparison.

You’ll have to write a thesis statement explaining the central point you want to make in your essay , so be sure to know in advance what connects your subjects and makes them worth comparing.

Comparisons in essays are generally structured in one of two ways:

  • The alternating method, where you compare your subjects side by side according to one specific aspect at a time.
  • The block method, where you cover each subject separately in its entirety.

It’s also possible to combine both methods, for example by writing a full paragraph on each of your topics and then a final paragraph contrasting the two according to a specific metric.

Comparing and contrasting in essays

Essays that require you to compare and contrast two or more subjects, ideas, places, or items are common.

They call for you to highlight the key similarities (compare) and differences (contrast) between them.

This guide contains all the information you need to become better at writing comparing and contrasting essays.

This includes: how to structure your essay, how to decide on the content, and some examples of essay questions.

Let’s dive in.

Compare and contrast definition

What Is Comparing and Contrasting?

Is compare and contrast the same as similarities and differences, what is the purpose of comparing and contrasting, can you compare and contrast any two items, how do you compare and contrast in writing, what are some comparing and contrasting techniques, how do you compare and contrast in college level writing, the four essentials of compare and contrast essays, what can you learn from a compare and contrast essay.

At their most basic, both comparing and contrasting base their evaluation on two or more subjects that share a connection.

The subjects could have similar characteristics, features, or foundations.

But while a comparison discusses the similarities of the two subjects, e.g. a banana and a watermelon are both fruit, contrasting highlights how the subjects or items differ from each other, e.g. a watermelon is around 10 times larger than a banana.

Any question that you are asked in education will have a variety of interesting comparisons and deductions that you can make.

Compare is the same as similarities.

Contrast is the same as differences.

This is because comparing identifies the likeness between two subjects, items, or categories, while contrasting recognizes disparities between them.

When you compare things, you represent them regarding their similarity, but when you contrast things, you define them in reference to their differences.

As a result, if you are asked to discuss the similarities and differences between two subjects, you can take an identical approach to if you are writing a compare and contrast essay.

In writing, the purpose of comparing and contrasting is to highlight subtle but important differences or similarities that might not be immediately obvious.

The purpose of comparing and contrasting

By illustrating the differences between elements in a similar category, you help heighten readers’ understanding of the subject or topic of discussion.

For instance, you might choose to compare and contrast red wine and white wine by pointing out the subtle differences. One of these differences is that red wine is best served at room temperature while white is best served chilled.

Also, comparing and contrasting helps to make abstract ideas more definite and minimizes the confusion that might exist between two related concepts.

Can Comparing and Contrasting Be Useful Outside of Academia?

Comparing enables you to see the pros and cons, allowing you to have a better understanding of the things under discussion. In an essay, this helps you demonstrate that you understand the nuances of your topic enough to draw meaningful conclusions from them.

Let's use a real-word example to see the benefits. Imagine you're contrasting two dresses you could buy. You might think:

  • Dress A is purple, my favorite color, but it has a difficult zip and is practically impossible to match a jacket to.
  • Dress B is more expensive but I already have a suitable pair of shoes and jacket and it is easier to move in.

You're linking the qualities of each dress to the context of the decision you're making. This is the same for your essay. Your comparison and contrast points will be in relation to the question you need to answer.

Comparing and contrasting is only a useful technique when applied to two related concepts.

To effectively compare two or more things, they must feature characteristics similar enough to warrant comparison.

In addition to this they must also feature a similarity that generates an interesting discussion. But what do I mean by “interesting” here?

Let’s look at two concepts, the Magna Carta and my third grade poetry competition entry.

They are both text, written on paper by a person so they fulfil the first requirement, they have a similarity. But this comparison clearly would not fulfil the second requirement, you would not be able to draw any interesting conclusions.

However, if we compare the Magna Carta to the Bill of Rights, you would be able to come to some very interesting conclusions concerning the history of world politics.

To write a good compare and contrast essay, it’s best to pick two or more topics that share a meaningful connection .

The aim of the essay would be to show the subtle differences or unforeseen similarities.

By highlighting the distinctions between elements in a similar category you can increase your readers’ understanding.

Alternatively, you could choose to focus on a comparison between two subjects that initially appear unrelated.

The more dissimilar they seem, the more interesting the comparison essay will turn out.

For instance, you could compare and contrast professional rugby players with marathon runners.

Can You Compare and Contrast in an Essay That Does Not Specifically Require It?

As a writer, you can employ comparing and contrasting techniques in your writing, particularly when looking for ideas you can later apply in your argument.

You can do this even when the comparison or contrast is not a requirement for the topic or argument you are presenting. Doing so could enable you to build your evaluation and develop a stronger argument.

Note that the similarities and differences you come up with might not even show up in the final draft.

While the use of compare and contrast can be neutral, you can also use it to highlight one option under discussion. When used this way, you can influence the perceived advantages of your preferred option.

As a writing style, comparing and contrasting can encompass an entire essay. However, it could also appear in some select paragraphs within the essay, where making some comparisons serves to better illustrate a point.

What Should You Do First?

Before you compare two things, always start by deciding on the reason for your comparison, then outline the criteria you will use to compare them.

Words and phrases commonly used for comparison include:

Comparison words and phrases

In writing, these words and phrases are called transitions . They help readers to understand or make the connection between sentences, paragraphs, and ideas.

Without transition words writing can feel clumsy and disjointed making it difficult to read. ProWritingAid’s transition report highlights all of a documents transitions and suggests that 25% of any sentences in a piece include a transition.

So, how do you form all of this into a coherent essay? It's a good idea to plan first, then decide what your paragraph layout will look like.

Venn diagrams are useful tool to start generating ideas. The, for your essay, you need to choose between going idea by idea and going point by point.

Using a Venn Diagram

A Venn diagram helps you to clearly see the similarities and differences between multiple objects, things, or subjects.

The writing tool comprises two, or more, simple, overlapping circles in which you list down the things that are alike (within the overlapping area) and those that differ (outside the overlapping area).

It’s great for brainstorming ideas and for creating your essay’s outline. You could even use it in an exam setting because it is quick and simple.

Going Subject by Subject

Going subject by subject is a structural choice for your essay.

Start by saying all you have to say on the first subject, then proceed to do the same about the second subject.

Depending on the length of your essay, you can fit the points about each subject into one paragraph or have several sections per each subject, ending with a conclusion.

This method is best for short essays on simple topics. Most university-level essays will go point by point instead.

Going Point by Point

Going point by point, or alternating, is the opposite essay structure from going subject by subject. This is ideal when you want to do more direct comparing and contrasting. It entails discussing one comparison point at a time. It allows you to use a paragraph to talk about how a certain comparing/contrasting point relates to the subjects or items you are discussing.

Alternatively, if you have lots of details about the subject, you might decide to use a paragraph for each point.

Different ways to compare and contrast

An academic compare and contrast essay looks at two or more subjects, ideas, people, or objects, compares their likeness, and contrasts their differences.

It’s an informative essay that provides insights on what is similar and different between the two items.

Depending on the essay’s instructions, you can focus solely on comparing or contrasting, or a combination of the two.

Examples of College Level Compare and Contrast Essay Questions

Here are eleven examples of compare and contrast essay questions that you might encounter at university:

Compare and contrast examples

  • Archaeology: Compare and contrast the skulls of homo habilis, homo erectus, and homo sapiens.
  • Art: Compare and contrast the working styles of any two Neoclassic artists.
  • Astrophysics: Compare and contrast the chemical composition of Venus and Neptune.
  • Biology: Compare and contrast the theories of Lamarck and Darwin.
  • Business: Compare and contrast 2 or more business models within the agricultural industry.
  • Creative writing: Compare and contrast free indirect discourse with epistolary styles.
  • English Literature: Compare and contrast William Wordsworth with Robert Browning.
  • Geography: Compare and contrast the benefit of solar panels with the benefit of wind turbines.
  • History: Compare and contrast WWI to WWII with specific reference to the causes and outcomes.
  • Medicine: Compare and contrast England’s health service with America’s health service.
  • Psychology: Compare and contrast the behaviorist theory with the psychodynamic theory.

So, the key takeaways to keep in mind are:

Have a basis for comparison. The two things need to have enough in common to justify a discussion about their similarities and disparities.

Don’t go back and forth when using the block method. The best way to write your essay is to begin with a paragraph discussing all the facets of the first topic. Then, move on to another paragraph and talk through all the aspects of the second subject.

You can use both alternating and blocking techniques. Combining the two approaches is also an option. You can apply the alternating method in some paragraphs, then switch and use the block method. This method will help you offer a much deeper analysis of the subjects.

Have a reason for comparing the two things. Only select the points of comparison that resonate with your purpose.

Compare and contrast, key takeaways

Comparing and contrasting are essential analytical skills in academic writing. When your professor issues you with such an essay, their primary goal is to teach you how to:

  • Engage in critical thinking
  • See and make connections between words or ideas
  • Move beyond mere descriptions or summaries to developing interesting analysis
  • Get a deeper understanding of the subjects or items under comparison, their key features, and their interrelationships with each other.

The benefits of comparing and contrasting

Ultimately, your essay should enlighten readers by providing useful information.

Compare & Contrast Essays How things are similar or different

Compare and contrast is a common form of academic writing, either as an essay type on its own, or as part of a larger essay which includes one or more paragraphs which compare or contrast. This page gives information on what a compare and contrast essay is , how to structure this type of essay, how to use compare and contrast structure words , and how to make sure you use appropriate criteria for comparison/contrast . There is also an example compare and contrast essay on the topic of communication technology, as well as some exercises to help you practice this area.

writing compare and contrast essay

To compare is to examine how things are similar, while to contrast is to see how they differ. A compare and contrast essay therefore looks at the similarities of two or more objects, and the differences. This essay type is common at university, where lecturers frequently test your understanding by asking you to compare and contrast two theories, two methods, two historical periods, two characters in a novel, etc. Sometimes the whole essay will compare and contrast, though sometimes the comparison or contrast may be only part of the essay. It is also possible, especially for short exam essays, that only the similarities or the differences, not both, will be discussed. See the examples below.

  • Compare and contrast Newton's ideas of gravity with those proposed by Einstein ['compare and contrast' essay]
  • Examine how the economies of Spain and China are similar ['compare' only essay]
  • Explain the differences between Achaemenid Empire and Parthian Empire ['contrast' only essay]

There are two main ways to structure a compare and contrast essay, namely using a block or a point-by-point structure. For the block structure, all of the information about one of the objects being compared/contrasted is given first, and all of the information about the other object is listed afterwards. This type of structure is similar to the block structure used for cause and effect and problem-solution essays. For the point-by-point structure, each similarity (or difference) for one object is followed immediately by the similarity (or difference) for the other. Both types of structure have their merits. The former is easier to write, while the latter is generally clearer as it ensures that the similarities/differences are more explicit.

The two types of structure, block and point-by-point , are shown in the diagram below.





Compare and Contrast Structure Words

Compare and contrast structure words are transition signals which show the similarities or differences. Below are some common examples.

  • both... and...
  • not only... but also...
  • neither... nor...
  • just like (+ noun)
  • similar to (+ noun)
  • to be similar (to)
  • to be the same as
  • to be alike
  • to compare (to/with)
  • Computers can be used to communicate easily, for example via email. Similarly/Likewise , the mobile phone is a convenient tool for communication.
  • Both computers and mobile phones can be used to communicate easily with other people.
  • Just like the computer, the mobile phone can be used to communicate easily with other people.
  • The computer is similar to the mobile phone in the way it can be used for easy communication.
  • In contrast
  • In comparison
  • By comparison
  • On the other hand
  • to differ from
  • to be different (from)
  • to be dissimilar to
  • to be unlike
  • Computers, although increasingly small, are not always easy to carry from one place to another. However , the mobile phone can be carried with ease.
  • Computers are generally not very portable, whereas the mobile phone is.
  • Computers differ from mobile phones in their lack of portability.
  • Computers are unlike mobile phones in their lack of portability.

Criteria for comparison/contrast

When making comparisons or contrasts, it is important to be clear what criteria you are using. Study the following example, which contrasts two people. Here the criteria are unclear.

  • Aaron is tall and strong. In contrast , Bruce is handsome and very intelligent.

Although this sentence has a contrast transition , the criteria for contrasting are not the same. The criteria used for Aaron are height (tall) and strength (strong). We would expect similar criteria to be used for Bruce (maybe he is short and weak), but instead we have new criteria, namely appearance (handsome) and intelligence (intelligent). This is a common mistake for students when writing this type of paragraph or essay. Compare the following, which has much clearer criteria (contrast structure words shown in bold).

  • Aaron and Bruce differ in four ways. The first difference is height. Aaron is tall, while Bruce is short. A second difference is strength. Aaron is strong. In contrast , Bruce is weak. A third difference is appearance. Aaron, who is average looking, differs from Bruce, who is handsome. The final difference is intelligence. Aaron is of average intelligence. Bruce, on the other hand , is very intelligent.

Title: There have been many advances in technology over the past fifty years. These have revolutionised the way we communicate with people who are far away. Compare and contrast methods of communication used today with those which were used in the past.

 
         
 
 

Before the advent of computers and modern technology, people communicating over long distances used traditional means such as letters and the telephone. Nowadays we have a vast array of communication tools which can complete this task, ranging from email to instant messaging and video calls. While the present and previous means of communication are similar in their general form , they differ in regard to their speed and the range of tools available . One similarity between current and previous methods of communication relates to the form of communication. In the past, both written forms such as letters were frequently used, in addition to oral forms such as telephone calls. Similarly , people nowadays use both of these forms. Just as in the past, written forms of communication are prevalent, for example via email and text messaging. In addition, oral forms are still used, including the telephone, mobile phone, and voice messages via instant messaging services. However , there are clearly many differences in the way we communicate over long distances, the most notable of which is speed. This is most evident in relation to written forms of communication. In the past, letters would take days to arrive at their destination. In contrast , an email arrives almost instantaneously and can be read seconds after it was sent. In the past, if it was necessary to send a short message, for example at work, a memo could be passed around the office, which would take some time to circulate. This is different from the current situation, in which a text message can be sent immediately. Another significant difference is the range of communication methods. Fifty years ago, the tools available for communicating over long distances were primarily the telephone and the letter. By comparison , there are a vast array of communication methods available today. These include not only the telephone, letter, email and text messages already mentioned, but also video conferences via software such as Skype or mobile phone apps such as WeChat, and social media such as Facebook and Twitter. In conclusion, methods of communication have greatly advanced over the past fifty years. While there are some similarities, such as the forms of communication , there are significant differences, chiefly in relation to the speed of communication and the range of communication tools available . There is no doubt that technology will continue to progress in future, and the advanced tools which we use today may one day also become outdated.

Compare & contrast essays examine the similarities of two or more objects, and the differences.

Cause & effect essays consider the reasons (or causes) for something, then discuss the results (or effects).

Discussion essays require you to examine both sides of a situation and to conclude by saying which side you favour.

Problem-solution essays are a sub-type of SPSE essays (Situation, Problem, Solution, Evaluation).

Transition signals are useful in achieving good cohesion and coherence in your writing.

Reporting verbs are used to link your in-text citations to the information cited.

Comparing and Contrasting

What this handout is about.

This handout will help you first to determine whether a particular assignment is asking for comparison/contrast and then to generate a list of similarities and differences, decide which similarities and differences to focus on, and organize your paper so that it will be clear and effective. It will also explain how you can (and why you should) develop a thesis that goes beyond “Thing A and Thing B are similar in many ways but different in others.”

Introduction

In your career as a student, you’ll encounter many different kinds of writing assignments, each with its own requirements. One of the most common is the comparison/contrast essay, in which you focus on the ways in which certain things or ideas—usually two of them—are similar to (this is the comparison) and/or different from (this is the contrast) one another. By assigning such essays, your instructors are encouraging you to make connections between texts or ideas, engage in critical thinking, and go beyond mere description or summary to generate interesting analysis: when you reflect on similarities and differences, you gain a deeper understanding of the items you are comparing, their relationship to each other, and what is most important about them.

Recognizing comparison/contrast in assignments

Some assignments use words—like compare, contrast, similarities, and differences—that make it easy for you to see that they are asking you to compare and/or contrast. Here are a few hypothetical examples:

  • Compare and contrast Frye’s and Bartky’s accounts of oppression.
  • Compare WWI to WWII, identifying similarities in the causes, development, and outcomes of the wars.
  • Contrast Wordsworth and Coleridge; what are the major differences in their poetry?

Notice that some topics ask only for comparison, others only for contrast, and others for both.

But it’s not always so easy to tell whether an assignment is asking you to include comparison/contrast. And in some cases, comparison/contrast is only part of the essay—you begin by comparing and/or contrasting two or more things and then use what you’ve learned to construct an argument or evaluation. Consider these examples, noticing the language that is used to ask for the comparison/contrast and whether the comparison/contrast is only one part of a larger assignment:

  • Choose a particular idea or theme, such as romantic love, death, or nature, and consider how it is treated in two Romantic poems.
  • How do the different authors we have studied so far define and describe oppression?
  • Compare Frye’s and Bartky’s accounts of oppression. What does each imply about women’s collusion in their own oppression? Which is more accurate?
  • In the texts we’ve studied, soldiers who served in different wars offer differing accounts of their experiences and feelings both during and after the fighting. What commonalities are there in these accounts? What factors do you think are responsible for their differences?

You may want to check out our handout on understanding assignments for additional tips.

Using comparison/contrast for all kinds of writing projects

Sometimes you may want to use comparison/contrast techniques in your own pre-writing work to get ideas that you can later use for an argument, even if comparison/contrast isn’t an official requirement for the paper you’re writing. For example, if you wanted to argue that Frye’s account of oppression is better than both de Beauvoir’s and Bartky’s, comparing and contrasting the main arguments of those three authors might help you construct your evaluation—even though the topic may not have asked for comparison/contrast and the lists of similarities and differences you generate may not appear anywhere in the final draft of your paper.

Discovering similarities and differences

Making a Venn diagram or a chart can help you quickly and efficiently compare and contrast two or more things or ideas. To make a Venn diagram, simply draw some overlapping circles, one circle for each item you’re considering. In the central area where they overlap, list the traits the two items have in common. Assign each one of the areas that doesn’t overlap; in those areas, you can list the traits that make the things different. Here’s a very simple example, using two pizza places:

Venn diagram indicating that both Pepper's and Amante serve pizza with unusual ingredients at moderate prices, despite differences in location, wait times, and delivery options

To make a chart, figure out what criteria you want to focus on in comparing the items. Along the left side of the page, list each of the criteria. Across the top, list the names of the items. You should then have a box per item for each criterion; you can fill the boxes in and then survey what you’ve discovered.

Here’s an example, this time using three pizza places:

Pepper’s Amante Papa John’s
Location
Price
Delivery
Ingredients
Service
Seating/eating in
Coupons

As you generate points of comparison, consider the purpose and content of the assignment and the focus of the class. What do you think the professor wants you to learn by doing this comparison/contrast? How does it fit with what you have been studying so far and with the other assignments in the course? Are there any clues about what to focus on in the assignment itself?

Here are some general questions about different types of things you might have to compare. These are by no means complete or definitive lists; they’re just here to give you some ideas—you can generate your own questions for these and other types of comparison. You may want to begin by using the questions reporters traditionally ask: Who? What? Where? When? Why? How? If you’re talking about objects, you might also consider general properties like size, shape, color, sound, weight, taste, texture, smell, number, duration, and location.

Two historical periods or events

  • When did they occur—do you know the date(s) and duration? What happened or changed during each? Why are they significant?
  • What kinds of work did people do? What kinds of relationships did they have? What did they value?
  • What kinds of governments were there? Who were important people involved?
  • What caused events in these periods, and what consequences did they have later on?

Two ideas or theories

  • What are they about?
  • Did they originate at some particular time?
  • Who created them? Who uses or defends them?
  • What is the central focus, claim, or goal of each? What conclusions do they offer?
  • How are they applied to situations/people/things/etc.?
  • Which seems more plausible to you, and why? How broad is their scope?
  • What kind of evidence is usually offered for them?

Two pieces of writing or art

  • What are their titles? What do they describe or depict?
  • What is their tone or mood? What is their form?
  • Who created them? When were they created? Why do you think they were created as they were? What themes do they address?
  • Do you think one is of higher quality or greater merit than the other(s)—and if so, why?
  • For writing: what plot, characterization, setting, theme, tone, and type of narration are used?
  • Where are they from? How old are they? What is the gender, race, class, etc. of each?
  • What, if anything, are they known for? Do they have any relationship to each other?
  • What are they like? What did/do they do? What do they believe? Why are they interesting?
  • What stands out most about each of them?

Deciding what to focus on

By now you have probably generated a huge list of similarities and differences—congratulations! Next you must decide which of them are interesting, important, and relevant enough to be included in your paper. Ask yourself these questions:

  • What’s relevant to the assignment?
  • What’s relevant to the course?
  • What’s interesting and informative?
  • What matters to the argument you are going to make?
  • What’s basic or central (and needs to be mentioned even if obvious)?
  • Overall, what’s more important—the similarities or the differences?

Suppose that you are writing a paper comparing two novels. For most literature classes, the fact that they both use Caslon type (a kind of typeface, like the fonts you may use in your writing) is not going to be relevant, nor is the fact that one of them has a few illustrations and the other has none; literature classes are more likely to focus on subjects like characterization, plot, setting, the writer’s style and intentions, language, central themes, and so forth. However, if you were writing a paper for a class on typesetting or on how illustrations are used to enhance novels, the typeface and presence or absence of illustrations might be absolutely critical to include in your final paper.

Sometimes a particular point of comparison or contrast might be relevant but not terribly revealing or interesting. For example, if you are writing a paper about Wordsworth’s “Tintern Abbey” and Coleridge’s “Frost at Midnight,” pointing out that they both have nature as a central theme is relevant (comparisons of poetry often talk about themes) but not terribly interesting; your class has probably already had many discussions about the Romantic poets’ fondness for nature. Talking about the different ways nature is depicted or the different aspects of nature that are emphasized might be more interesting and show a more sophisticated understanding of the poems.

Your thesis

The thesis of your comparison/contrast paper is very important: it can help you create a focused argument and give your reader a road map so they don’t get lost in the sea of points you are about to make. As in any paper, you will want to replace vague reports of your general topic (for example, “This paper will compare and contrast two pizza places,” or “Pepper’s and Amante are similar in some ways and different in others,” or “Pepper’s and Amante are similar in many ways, but they have one major difference”) with something more detailed and specific. For example, you might say, “Pepper’s and Amante have similar prices and ingredients, but their atmospheres and willingness to deliver set them apart.”

Be careful, though—although this thesis is fairly specific and does propose a simple argument (that atmosphere and delivery make the two pizza places different), your instructor will often be looking for a bit more analysis. In this case, the obvious question is “So what? Why should anyone care that Pepper’s and Amante are different in this way?” One might also wonder why the writer chose those two particular pizza places to compare—why not Papa John’s, Dominos, or Pizza Hut? Again, thinking about the context the class provides may help you answer such questions and make a stronger argument. Here’s a revision of the thesis mentioned earlier:

Pepper’s and Amante both offer a greater variety of ingredients than other Chapel Hill/Carrboro pizza places (and than any of the national chains), but the funky, lively atmosphere at Pepper’s makes it a better place to give visiting friends and family a taste of local culture.

You may find our handout on constructing thesis statements useful at this stage.

Organizing your paper

There are many different ways to organize a comparison/contrast essay. Here are two:

Subject-by-subject

Begin by saying everything you have to say about the first subject you are discussing, then move on and make all the points you want to make about the second subject (and after that, the third, and so on, if you’re comparing/contrasting more than two things). If the paper is short, you might be able to fit all of your points about each item into a single paragraph, but it’s more likely that you’d have several paragraphs per item. Using our pizza place comparison/contrast as an example, after the introduction, you might have a paragraph about the ingredients available at Pepper’s, a paragraph about its location, and a paragraph about its ambience. Then you’d have three similar paragraphs about Amante, followed by your conclusion.

The danger of this subject-by-subject organization is that your paper will simply be a list of points: a certain number of points (in my example, three) about one subject, then a certain number of points about another. This is usually not what college instructors are looking for in a paper—generally they want you to compare or contrast two or more things very directly, rather than just listing the traits the things have and leaving it up to the reader to reflect on how those traits are similar or different and why those similarities or differences matter. Thus, if you use the subject-by-subject form, you will probably want to have a very strong, analytical thesis and at least one body paragraph that ties all of your different points together.

A subject-by-subject structure can be a logical choice if you are writing what is sometimes called a “lens” comparison, in which you use one subject or item (which isn’t really your main topic) to better understand another item (which is). For example, you might be asked to compare a poem you’ve already covered thoroughly in class with one you are reading on your own. It might make sense to give a brief summary of your main ideas about the first poem (this would be your first subject, the “lens”), and then spend most of your paper discussing how those points are similar to or different from your ideas about the second.

Point-by-point

Rather than addressing things one subject at a time, you may wish to talk about one point of comparison at a time. There are two main ways this might play out, depending on how much you have to say about each of the things you are comparing. If you have just a little, you might, in a single paragraph, discuss how a certain point of comparison/contrast relates to all the items you are discussing. For example, I might describe, in one paragraph, what the prices are like at both Pepper’s and Amante; in the next paragraph, I might compare the ingredients available; in a third, I might contrast the atmospheres of the two restaurants.

If I had a bit more to say about the items I was comparing/contrasting, I might devote a whole paragraph to how each point relates to each item. For example, I might have a whole paragraph about the clientele at Pepper’s, followed by a whole paragraph about the clientele at Amante; then I would move on and do two more paragraphs discussing my next point of comparison/contrast—like the ingredients available at each restaurant.

There are no hard and fast rules about organizing a comparison/contrast paper, of course. Just be sure that your reader can easily tell what’s going on! Be aware, too, of the placement of your different points. If you are writing a comparison/contrast in service of an argument, keep in mind that the last point you make is the one you are leaving your reader with. For example, if I am trying to argue that Amante is better than Pepper’s, I should end with a contrast that leaves Amante sounding good, rather than with a point of comparison that I have to admit makes Pepper’s look better. If you’ve decided that the differences between the items you’re comparing/contrasting are most important, you’ll want to end with the differences—and vice versa, if the similarities seem most important to you.

Our handout on organization can help you write good topic sentences and transitions and make sure that you have a good overall structure in place for your paper.

Cue words and other tips

To help your reader keep track of where you are in the comparison/contrast, you’ll want to be sure that your transitions and topic sentences are especially strong. Your thesis should already have given the reader an idea of the points you’ll be making and the organization you’ll be using, but you can help them out with some extra cues. The following words may be helpful to you in signaling your intentions:

  • like, similar to, also, unlike, similarly, in the same way, likewise, again, compared to, in contrast, in like manner, contrasted with, on the contrary, however, although, yet, even though, still, but, nevertheless, conversely, at the same time, regardless, despite, while, on the one hand … on the other hand.

For example, you might have a topic sentence like one of these:

  • Compared to Pepper’s, Amante is quiet.
  • Like Amante, Pepper’s offers fresh garlic as a topping.
  • Despite their different locations (downtown Chapel Hill and downtown Carrboro), Pepper’s and Amante are both fairly easy to get to.

How to Start a Compare and Contrast Essay

Compare and contrast essays are often assigned to students because they promote critical thinking, analytical reasoning and organized writing. A compare and contrast essay should look at a subject in a new way, with fresh insight, using the similarities and the differences between two topics or two perspectives on one topic.

Sample Outline

writing compare and contrast essay

Brainstorming Your Topic

Step 1 Understand the structure of a compare and contrast essay.

  • If your instructor has already given you your topic, you may be contrasting two things that could go into the same category, but are different from each other. For example, cats and dogs are both animals, but they are different from each other in many ways. The pro-life view on abortion, and the pro-choice view on abortion could both fit under the category of a human rights issue, but they are two very distinct views or positions.

Step 2 Make a list of similarities and differences.

  • Try to write as many similarities and differences you can think of. For example: cats and dogs are both domesticated animals. But cats have different temperaments than dogs, and cats are known to be indoor pets, while dogs tend to need to be walked and played with outside on a constant basis.
  • Think about at least one or two meaningful differences and similarities between the two subjects. For example, a compare and contrast between abortion rights could lead to meaningful notes like: The pro-life stance views fetuses are full formed humans and are often based in religious beliefs, while the pro-choice stance views fetuses as undeveloped eggs and are often based in scientific beliefs.
  • To focus your list, choose categories (or possible supporting points for your paper) to classify the similarities and differences between the two subjects. For example, for the abortion rights topic, you may choose categories like: legal details, women's rights, scientific stance, and religious beliefs. You can then separate each item on the list into these categories.

Step 3 Create a Venn diagram of your topic.

  • Once you are done listing 10-15 differences and 5-7 similarities, circle the most important items in each list. Then, match at least three opposites from one circle to the other circle.
  • Review the list and look for three different categories that describe these traits. For example, for the abortion rights topic, you may have “scientific studies of the fetus” on the pro-choice side, and “belief in life of the fetus” on the pro-life side. One possible category could then be the debate of the life of a fetus.

Step 4 Answer the 5 W's and H questions.

  • If you're compare and contrasting two historical periods or events, you may ask: When did they occur (the dates and the duration)? What happened or changed during each event? Why are they significant? Who were the important people involved? How did the events occur, and what consequences did they have later in history?
  • If you're compare and contrasting two ideas or theories, you may ask: What were they about? How did they originate? Who created them? What is the central focus, claim, or goal of each theory? How do the theories apply to situations/people/things, etc.? What kind of evidence is used to support each theory?
  • If you're compare and contrasting two pieces of art, you may ask: What does each piece of art describe or depict? What is their tone or mood? What themes do they address? Who created them? When were they created? How do the creators of the artworks describe their own work? Why do you think the artworks were created as they were?
  • If you're compare and contrasting two people, you may ask: Where is each person from? How old are they? What, if anything, are they known for? How do they identify themselves in terms of gender, race, class, etc? Do the two people have any relationship to each other? What does each person do? Why is each person interesting? What are the defining features of each person?

Step 5 Note any gaps in your knowledge or research.

  • Your instructor may also ask for a discussion of more than one similarity and difference between the two topics or two perspectives. Identify any gaps in your knowledge and prepare to do research so you can better compare and contrast the two topics in your essay.

Creating an Outline

Step 1 Compose your thesis...

  • Your thesis should note the key similarities and differences of both subjects. For example: “Dogs and cats are both seen as ideal, domesticated pets, but their temperaments and breeding set them apart.”
  • Your thesis should also be able to answer the question, “So what? Why should anyone care about the positives and the negatives of owning a cat or a dog?” A reader may also wonder why you chose to look at cats and dogs, and not other domesticated pets like birds, reptiles, or rabbits. Your thesis statement is much stronger if you address these questions, and a stronger thesis can lead to a stronger essay.
  • The revised thesis may look like: “Dogs and cats are both considered ideal, domesticated pets, and prove more popular than other domesticated animals like birds or rabbits, but the low maintenance and particular temperament of cats makes them better pets for a variety of households.” A more concise thesis, which allows for a more open discussion of both options, may look like: “Both cats and dogs make excellent domesticated pets, but an appropriate choice depends on the pet owner's lifestyle, finances, and living accommodations.”

Step 2 Organize your paper by the block method.

  • Introduction: Introduce the general topic, then introduce the two specific topics. End with your thesis, which addresses what is going to be covered in the essay.
  • Leads into Aspect 1: Lifestyle, with at least two details. For example, how cats do not have to watched during the day, and are easier to get care if the owner travels or is often not home.
  • Leads into Aspect 2: Cost, with at least two details. For example, how food and healthcare are less expensive for cats and how cats are less likely to cause property damage to the owner's home.
  • Leads into Aspect 3: Living accommodations, with at least two details. For example, how cats do not take up a lot of space and they are less intrusive as they do not require daily walks or constant play.
  • End the paragraph with a transition sentence.
  • Body paragraph 2 will follow the same structure, with three Aspects and two supporting details for each aspect.
  • Body paragraph 3 can follow the same structure as Body paragraph 2 and 3. Or it can be a paragraph that develops the comparison made in the previous two paragraphs. You can use scientific data, crowd sourced feedback, or a personal experience. For example, you may have been in a position where you had to compare and contrast adopting a dog or a cat and made your decision based on your lifestyle, finances, and living situation. This could serve as a personal experience to back up your previous arguments.
  • Conclusion: Contains a summary of your main points, a restating of your thesis, an evaluation of your analysis and any future developments that may sway your compare and contrast to one topic over the other.

Step 3 Use a point by point structure.

  • Introduction: Introduce the general topic, then introduce the two specific topics. End with your thesis, which addresses what is going to covered in the essay.
  • Leads into Topic 1, Aspect 1: Cats, with two details supporting cats in the argument. For example, how cats do not have to watched during the day, and are easier to get care if the owner travels or is often not home.
  • Leads into Topic 2, Aspect 1: Dogs, with two details contrasting dogs to the previous argument. For example, how dogs are pack animals and shouldn't be left alone for long periods of time, and how it can be difficult to find care for a dog when the owner is away.
  • Ends with a transition sentence.
  • Body paragraph 2 will follow the same structure, with a discussion of Topic 1 and Topic 2 in relation to Aspect 2, for example: “Cats are less expensive to own and care for.” There should be two supporting details for each topic.
  • Body paragraph 3 will follow the same structure, with a discussion of Topic 1 and Topic 2 in relation to Aspect 3, for example: “Cats need less special house accommodations than dogs.” There should be two supporting details for each topic.

Writing an Introduction

Step 1 Be assertive and clear.

  • You should also avoid announcing your intentions in a straightforward and formal way. For example, skip statements like “In this paper, I will” or “The purpose of this essay is to”.
  • Instead, your reader should be able to perceive the purpose of your essay through the first two sentences in your beginning paragraph.

Step 2 Create a hook for your first sentence.

  • An interesting or surprising example: This could be a personal experience of when a cat proved to be a better pet than a dog, or a scientific study that shows the differences between cats and dogs.
  • A provocative quotation: This could be from a source you used for your essay or one that feels relevant to your topic.
  • A vivid anecdote: An anecdote is a very short story that carries moral or symbolic weight. Think of an anecdote that might be a poetic or powerful way to start your essay. You can also look through your research for your essay for any note worthy anecdotes.
  • A thought provoking question: Think of a question that will get your reader thinking and engaged in your topic. For example: “Did you always wish you had a cat but ended up with a dog when you were growing up?”

Step 3 Revise your introduction once you complete the essay.

  • The writing process can be an important way to organize your ideas, think through certain points, and refine your thoughts. Writing or revising the introduction once you are done your essay will ensure the introduction matches the body of your essay.

To start a compare and contrast essay, start by making a list of similarities and differences between your subjects. Once you have a clearer idea of how your subjects work in relation to each other, you can work on your introduction. Think about ways to hook or grab your reader’s attention with your opening, like giving a surprising or interesting fact or a vivid anecdote. You can also ask a thought-provoking question or use a provocative quotation. Then, introduce your general topic. Once you give your reader a bit of context, you can discuss your two specific subjects in a bit more detail before stating your thesis. Your thesis should note the main similarities and differences between both subjects. For example, “Dogs and cats are both seen as ideal domestic pets, but their temperaments and breeding set them apart.” To learn how to organize your compare and contrast essay, keep reading!

How to Write a Compare and Contrast Essay

How to Write a Compare and Contrast Essay

  • 5-minute read
  • 9th March 2021

In a compare and contrast essay , you look at the similarities and differences between two subjects. How do you write one, though? Key steps include:

  • Pick two things to compare based on the assignment you were given.
  • Brainstorm the similarities and differences between your chosen subjects.
  • Choose a structure for your essay and plan how you will write it.
  • Write up your comparison and use evidence to support your argument.
  • Revise and proofread your essay to make sure it is perfect.

For more advice on each stage, check out our guide below.

1. Pick Two Subjects to Compare and Contrast

A compare and contrast assignment will ask you, unsurprisingly, to compare and contrast two things. In some cases, the assignment question will make this clear. For instance, if the assignment says “Compare how Mozart and Beethoven use melody,” you will have a very clear sense of what to write about!

Other times, you will have a choice of what to compare. In this case, you will want to pick two things that are similar enough to make a useful comparison.

For example, comparing Mozart and Beethoven makes sense because both are classical composers. This means there will be lots of points of comparison between them. But comparing Mozart to a Ferrari SF90 Stradale would just be confusing: one is a renowned composer and musician, the other is a high-end sports car, so they have very little in common that we could usefully compare.

Wolfgang Amadeus Mozart

At the same time, the things you pick should be different enough that you can find points of contrast. Were you asked to compare the calorific content of two types of fast food, for example, it might not make sense to compare hamburgers and cheeseburgers as they are too similar. But you could compare hamburgers and pizzas since both are forms of fast food but they differ in other respects.

As such, if you need to pick the subjects of your essay, read your assignment question carefully and try to find two things that will produce a helpful comparison.

2. Brainstorm Their Similarities and Differences

The next step is to brainstorm similarities and differences between your chosen subjects. You can do this as a simple list, but you could also use a Venn diagram .

This is a set of overlapping circles, each of which represents one subject. You can then add characteristics to each circle, with anything your subjects have in common going in the overlapping bit in the middle.

Once you’ve listed characteristics, you’ll need to pick out the similarities and differences relevant to your essay. If you were assigned a question, use this to guide your choices. Otherwise, look for features that seem surprising or interesting and plan your essay around these. The key is to pick points of comparison that help us to understand each thing better, or where the similarities and differences show us something that we might not have expected or noticed otherwise.

3. Choose a Structure for Your Essay

As with any essay, you will want to start with a short introduction where you introduce your topic and what you will argue. Beyond this, most compare and contrast essays are structured in one of two ways. Decide which approach to take before you write your essay outline :

  • Divide by subject – Cover each subject in turn, looking at the key features you’ve identified in the previous step. You can then include a final section where you highlight what comparing the subjects tell us.
  • Divide by individual points – Break your essay down into a series of sections. Each section will then focus on one of the key features you’ve identified, explaining the similarities and differences between your chosen subjects.

For instance, if you were comparing two novels, you could write about each novel in turn and then compare them at the end. Alternatively, you could structure your essay so that each section covers an individual idea (e.g., one on structure, one on characters, one on language), looking at how each book uses these things.

In either case, you will want to end on a conclusion where you summarize what the comparison has shown us about the two subjects.

4. Use Supporting Evidence for Your Argument

It is important that you also back up your statements with supporting evidence. In some cases, this will simply involve pointing to the features of each subject that you’re discussing (e.g., citing specific parts of the novels you’re comparing).

However, you can also do extra research to back up your arguments. Were you comparing two countries’ economic performance, for example, you could use statistics from other studies or reports to show the similarities and differences.

5. Proofread Your Compare and Contrast Essay

Once you have a first draft of your compare and contrast essay, take a break. If you have time, leave it overnight. The aim is to come back to it with fresh eyes and reread it, looking for any areas you could improve. After this, you can redraft your essay to make sure your argument is clear, concise, and convincing.

It is also a good idea to have your essay proofread before submitting it. This will ensure your work is error free and help you get the marks you deserve.
