Comparing and Contrasting in an Essay | Tips & Examples
Comparing and contrasting is an important skill in academic writing. It involves taking two or more subjects and analyzing the differences and similarities between them.
You might find yourself comparing all kinds of things in an academic essay: historical figures, literary works, policies, research methods, etc. Doing so is an important part of constructing arguments.
When should I compare and contrast?
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.
Making effective comparisons
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 as a brainstorming tool
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.
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.
Structuring your comparisons
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:
- Point of comparison A
- Subject 1
- Subject 2
- Point of comparison B
- Subject 1
- Subject 2
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:
- Subject 1
- Point of comparison A
- Point of comparison B
- Subject 2
- Point of comparison A
- Point of comparison B
Mouse over the example paragraph below to see how this approach works.
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.

Frequently asked questions about comparing and contrasting
- When do I need to compare and contrast?
-
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.
- How do I choose subjects to compare and contrast?
-
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.
- How do I compare and contrast in a structured way?
-
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.
