I was reading the Grammarly Blog, and I was frustrated by the formulaic offerings on how to write different types of essays. I was particularly concerned with how formal their advice is, and considering I am a grammar nerd who believes that grammar is not merely the formal rules of a language, but also a frame for a worldview, I thought there was more at stake than simply being able to produce readable work. A good compare-and-contrast essay should also explain why it is a very useful tool.  That is, you may get assigned such an essay in high school or University, but did you know that gaining self-clarity and communicating that to others is a moment of human development? Thus learning the tricks of the academic trade is not a mere skill that gets you to a degree, but it may also help you become a better person.

 One of the key jobs of academic work is to clear up the confusion between ideas, methods, and concepts that closely resemble one another. A compare-and-contrast essay identifies the similarities and differences between two or more subjects. It is an appropriate tool for showing what separates and unites related ideas or concepts and is important to use if the subjects are often confused for each other or unjustly lumped together. 

Compare-and-contrast essays have a lot in common with other essay types, but differ in many ways, too—an object-lesson statement in comparing and contrasting. By seeing the differences and similarities, the reader better understands each of the subjects by using the other subject as a frame of reference. In other words, a compare-and-contrast essay considers two subjects together to provide the proper contrast to highlight and clarify ideas.

Here, I want to explain how to write a compare-and-contrast essay, including some advanced tips and examples. You will find explanations on how to structure your points and how to frame your thesis. To start with, let’s take a broader look at why comparison essays are so useful. 

Purpose of a compare-and-contrast essay

Let’s say you want to write an essay about how great renewable resources are, but you spend a lot of your time explaining how fossil fuels work. To truly understand why renewable resources are so amazing, your reader needs a little background on their alternative, fossil fuels—but the essay’s attention is divided so equally that it is as if there are two topics. That’s when compare-and-contrast essays function at their best. If two topics relate to each other or define each other, you can better explain them both by showcasing their similarities and differences. That goes double for topics that are often conflated or confused for each other; it helps readers when someone points out exactly what’s the same about them and what’s different. 

Unlike argumentative essays or persuasive essays, compare-and-contrast essays deal with multiple topics instead of focusing on one. The downside is that they don’t describe the individual subjects in as much as much depth as single-topic essays. They’re also a common assignment for college essays since they show the instructor how well you grasp both subjects. 

How to write a compare-and-contrast essay 

When writing a compare-and-contrast essay, it helps to be clear about two things: what your thesis is (the subject matter) and how you plan to structure it. 


First things first: You need to choose which subjects you’re comparing, and what is the point of the comparison. This isn’t always easy, especially if you have to pick the subjects on your own. 

As helpful inspiration, here are some compare-and-contrast essay example topics:

  • Opposing options for a certain category 
    • fossil fuels and renewable resources
    • Android phones and IOS phones 
  • Related works of arts or cultural movements
    • 1984 and Brave New World
    • ’80s punk rock music and ’90s grunge music
  • People who are similar, connected or associated with each other
    • Mohandas Ghandi and Nelson Mandela
  • The state of affairs at different time periods
    • Toronto in the 1700s and Toronto now
    • the Civil Rights Movement before and after President Obama
  • Two different but related places  
    • North America and Western Europe
  • Opposing theories or beliefs
    • Newtonian gravity or the Special Theory of Relativity
    • evolution and creationism
  • Opposing viewpoints or opinions
    • Capitalism and Communism
  • Topics that are often confused with each other
    • fascism and despotism

Once you’ve settled on your subjects, you can begin generating ideas. It helps to first list all the similarities and differences between your subjects. When you see them all written down, you can start formulating connections and decide what structure to use for your compare-and-contrast essay. If you’re stuck, try making a Venn diagram. This is a visual aid that helps you understand which characteristics your subjects share, and which ones are exclusive. 

Looking at your lists, you can then decide on the thesis. To do so, ask yourself a few questions: What are you trying to show in your compare-and-contrast essay? What do you want your reader to take away? Remember to place your thesis in a context that the reader cares about. If you want your reader to understand the difference between Thomas Edison and Elon Musk so that they better appreciate the revolutions Edison began, then you may want to talk about the fundamental differences and significance of Edison’s work in his context and demonstrate that this was more important than the work that Elon Musk is doing. 


Briefly, your compare-and-contrast essay should follow a simple format of beginning, middle, and end: 

  • Introduction: where you explain your thesis or what your essay will discuss
  • Body: where you actually list the similarities and differences of your subjects; the largest section
  • Conclusion: where you wrap up and summarize your points

The introduction, usually one or two paragraphs, should include a thesis statement and some foreshadowing for the reader to know what to expect for the rest of your essay. You can write your introduction following the same guidelines as other essay types, though be sure to mention all your subjects. 

It’s the body where compare-and-contrast essays get tricky. Do you write about both subjects at the same time, or switch back and forth? Let’s talk deeper on this below. 

How to structure a compare-and-contrast essay

The hardest part of structuring a compare-and-contrast essay is knowing when to talk about which subject. Essentially, you have three options: 

  • block method (subject by subject): You discuss one subject in full and then move on to the next subject.
  • alternating method (point by point): You discuss one subject’s take on a certain aspect and then another subject’s take immediately afterward, followed by a new aspect.
  • similarities and differences: You discuss all the similarities between your subjects and then all the differences, or vice versa (differences first and then similarities).

No matter which option you choose, you have to pay particular attention to topic sentences. Paragraphs in compare-and-contrast essays can get complicated, so it’s crucial to have a good topic or introduction sentence for each paragraph to make the flow of ideas clear. 

Block method (subject by subject),

The block method is usually divided into paragraphs: a paragraph about one subject and then a new paragraph about another subject. Take the compare-and-contrast essay example When Nothing Lies Beyond the Mask: Comparing Moby Dick and The Raven. In the first paragraph after the introduction, the author talks only about Ahab from Moby Dick, but in the next paragraph talks only about the narrator from The Raven. Each subject gets its own paragraph. 

Using the block method, you can go back and forth like this for pages, covering as many topics as you need. This approach is best for giving each subject its own attention but tends to slightly weaken the connection between the two. 

Alternating method (point by point)

As another option, you can break paragraphs up by a specific topic and issue, and in each paragraph discuss both or all subjects. Let’s look at another compare-and-contrast essay example, The Reality of Science Fiction: Comparing Clarke to Cruise. Here, both subjects are discussed in the same paragraph, one right after another. 

This approach works best when you want to emphasize the connection between your subjects, or lack thereof. In our example above, the author wishes to highlight just how different the aliens of Arthur Clarke are from those of other authors, particularly H. G. Wells. To emphasize this, the essay author juxtaposes the two points right next to each other in the same paragraph. 

Similarities and differences

The third option is quite similar to the alternating approach, with each subject being discussed side by side in the same paragraph. However, the paragraphs aren’t divided by different topics, but instead by what the subjects have in common and what they don’t. 

Take a look at the compare-and-contrast essay example Government by the People, for the People has Perished from the Earth, which compares the dystopias of George Orwell’s 1984 and Yevgeny Zamyatin’s We. The first paragraph after the introduction discusses what the governments in the two books have in common, but the next paragraph explains how they differ. 

This method works best if you want to focus on a particular similarity or difference between your subjects, or if you want to build up to a powerful conclusion or reveal at the end. To be honest, I like the reveal at the end; it makes a stronger impact. However, if the person who is reading your work reads your work often, then don’t overuse it.

The writing process for compare-and-contrast essays

Want to know how to write a compare-and-contrast essay step by step? The writing process is the same as all essay writing, although adapted specifically for drawing comparisons:


Brainstorming — As mentioned above, this should involve listing all the similarities and difficulties; creating a Venn diagram is a useful method. 

Preparation — Looking at your brainstorming lists, decide which structuring method would best get your point across: block, alternating, or similarities/differences. 

Drafting — Here you write your rough draft; this is the longest and toughest phase. But if you have thoroughly done your planning, drafting can go quite smoothly. Hannah Arendt, one of the most prolific writers of the twentieth century, says: “Sometimes I [formulate ideas easily]; sometimes I don’t.”But in general… I never write until I can, so to speak, take dictation from myself.” 


Revising — Does the structure you’ve chosen work? With the first draft finished, you can more easily identify any areas that need to be fixed, revised, or rewritten from scratch. Unlike proofreading below, revising consists in working on the overall structure, and making certain ideas within the article transition smoothly to create a kind of flow. Your reader should experience getting to the end of your essay without feeling like they have had to labour through it.  

Proofreading — Finally, you want to make sure you corrected all the spelling and grammatical mistakes in your draft. 

Tips for writing compare-and-contrast essays 

Beyond knowing the full process for crafting a compare-and-contrast essay, it helps to learn a few tips to ensure it shines.

In other words, choose topics that have plenty in common, otherwise, your essay will be all contrasting and no comparing. Typically, subjects in compare-and-contrast essays share a strong connection, such as two people in the same profession or two products in the same category. 

Without this unifying thread, the reader is left wondering, “What’s the point of comparing these two things?” Not only will it confound your audience, but you’ll also struggle more to come up with points when writing. Solve these problems before they start by smartly choosing your subjects at the beginning. 

Write for clarity

Essays with only one subject can be confusing enough—imagine how complicated it gets with two or more subjects. One of the biggest obstacles with compare-and-contrast essays is communicating clearly so your reader knows which points relate to which subject, and what conclusion the entire essay is building toward. 

But when you’re in the heat of a writing session, it can be difficult—and distracting—to stop and evaluate your work for clarity.

There are online tools to help with clarity, such as Grammarly and the spelling and grammar checker in a word processing program. But these tend to be formulaic, and are based on algorithms. I do not recommend those tools. I recommend taking a break after the drafting process, and coming back to your writing again with a reader hat on. Then read your writing out loud. Your ear will help you to catch awkward phrasings and points of the essay that need revision. Take a break, and come back again as many times as needed, or as time allows.
