When writing an essay, preparing a report, or comparing two products, you may wonder whether to use “compared to” or “in comparison with.” Both expressions are correct in English, but they differ slightly in structure, tone, and how naturally they fit into a sentence. Understanding these differences will help you choose the right expression for everyday conversations, academic writing, and professional communication.
Quick Answer
Both “compared to” and “in comparison with” are correct English expressions. They introduce comparisons, but they are used in slightly different ways.
| Expression | Meaning | Main use |
| Compared to | When considering one thing in relation to another | Everyday English, essays, reports, and direct comparisons |
| In comparison with | When examining similarities or differences between two things | Formal writing, analysis, and detailed comparisons |
Examples:
- Compared to: Compared to last year, our sales have increased significantly.
- In comparison with: In comparison with last year, this year’s sales have increased significantly.
Both sentences are grammatically correct and communicate essentially the same idea. The first expression is generally more concise, while the second often sounds more formal or analytical.

Meaning and Definition
Meaning of Compared To
“Compared to” means considering one person, object, situation, or result in relation to another to identify similarities, differences, or relative qualities.
People commonly use it to explain how something has changed or how two things differ in size, quality, cost, performance, or other characteristics.
For example:
Compared to my old phone, this one has a much better camera.
The sentence explains the new phone’s camera quality by using the old phone as a reference point.
Definition of Compared To
Compared to is a comparative expression consisting of the past participle of the verb compare and the preposition to. It introduces a reference point against which something is evaluated or described.
It can appear at the beginning of a sentence, within a sentence, or after a noun phrase.
Examples:
- Compared to other candidates, Maya has more experience.
- This model is inexpensive compared to its competitors.
- The current results are better compared to those from last month.
The expression can function in both formal and informal contexts. In some sentences, particularly those involving measured differences, “compared with” may be the more traditional choice.
Meaning of In Comparison With
“In comparison with” means when something is examined or considered alongside another thing to identify similarities or differences.
It often introduces a reference point in a discussion, report, or analysis.
For example:
In comparison with the previous model, the new design uses less energy.
The sentence compares the energy consumption of two models.
Definition of In Comparison With
In comparison with is a prepositional phrase that introduces the person, object, situation, or standard against which something is compared.
The phrase commonly appears at the beginning of a sentence or within a larger sentence. It is especially useful when presenting observations, evidence, or analytical conclusions.
Examples:
- In comparison with other applicants, he has extensive experience.
- The second proposal appears more practical in comparison with the first.
- In comparison with urban areas, some rural communities have fewer public transportation options.
The phrase does not change its form according to tense or number. Its function is to establish a relationship between the things being discussed.
Main Difference
The main difference between “compared to” and “in comparison with” is their grammatical structure and typical style, not their basic meaning. Both can describe similarities and differences, and both can be used in formal writing.
| Feature | Compared to | In comparison with |
| Grammatical structure | Past participle phrase | Prepositional phrase |
| Basic meaning | Evaluated in relation to something else | Considered alongside something else |
| Tone | Direct and concise | Often more formal or analytical |
| Everyday conversation | Very natural | Correct, but sometimes less conversational |
| Academic writing | Appropriate | Appropriate |
| Reports and analysis | Common | Useful for introducing comparisons |
| Sentence position | Beginning, middle, or end | Often at the beginning or middle |
| Correctness | Correct | Correct |
Consider these examples:
- Compared to: Compared to the old system, the new system is faster.
- In comparison with: In comparison with the old system, the new system is faster.
Both sentences communicate the same central idea. The choice depends on the sentence’s rhythm, context, and intended tone.
One related distinction is worth understanding: “compared to” and “compared with” are also both correct. Some traditional style guides prefer “compared to” for likening one thing to another and “compared with” for examining two things side by side. However, modern usage often overlaps, so this distinction is not an absolute grammatical rule.
Which One Is Correct?
Both “compared to” and “in comparison with” are grammatically correct. Neither expression is inherently wrong, and neither is restricted to a single variety of English.
Choose “compared to” when you want a short, direct comparison:
- Compared to last month, expenses are lower.
- This laptop is lighter compared to my previous one.
Choose “in comparison with” when you want to introduce a comparison in a more analytical style:
- In comparison with last month, expenses are lower.
- In comparison with the previous model, the device offers better performance.
For most sentences, either expression can work. However, a shorter construction is often clearer than a longer one when both communicate the same idea.
For example:
- Concise: The new model costs less than the old one.
- Also correct: In comparison with the old model, the new one costs less.
The best choice is the expression that makes the comparison easiest to understand.
Grammar and Usage
Understanding how each expression functions makes it easier to use it correctly.
1. Grammar of Compared To
“Compared to” consists of compared, the past participle of compare, followed by the preposition to.
It commonly appears in these patterns:
Pattern 1: Compared to + noun
- Compared to my brother, I am quite tall.
- Compared to other options, this plan is affordable.
Pattern 2: Adjective + compared to + noun
- This room is small compared to the other one.
- The new version is more reliable compared to the previous version.
Pattern 3: Compared to + noun at the beginning of a sentence
– Compared to last year, our performance has improved.
In this last pattern, the opening phrase establishes the basis of the comparison. The following clause explains what is being compared.
2. Grammar of In Comparison With
“In comparison with” consists of the noun comparison, preceded by in and followed by with.
It commonly appears in these patterns:
Pattern 1: In comparison with + noun
- In comparison with other applicants, Lena has considerable experience.
- In comparison with the original design, the revised version is simpler.
Pattern 2: Adjective + in comparison with + noun
- The apartment is inexpensive in comparison with similar properties.
- The results were impressive in comparison with previous findings.
Pattern 3: In comparison with + reference point, main clause
– In comparison with last year’s figures, this year’s results show steady growth.
The phrase introduces the reference point used to evaluate the subject of the sentence.

3. Tense and Number
Neither expression changes according to the tense of the main verb or whether the nouns are singular or plural.
Examples:
- Compared to last year, sales are higher.
- Compared to last year, sales were higher.
- In comparison with last year, sales have been higher.
- In comparison with previous studies, the findings are consistent.
The tense belongs to the main clause. The expressions themselves do not need to change.
4. Formal and Informal Usage
Both expressions are suitable for formal and informal communication.
However, “compared to” is often more natural in everyday conversation because it is concise. “In comparison with” can be useful when presenting data, explaining research findings, or developing a detailed argument.
For example:
- Conversation: This restaurant is cheap compared to the one we visited yesterday.
- Business report: In comparison with the previous quarter, operating costs decreased.
These are stylistic tendencies rather than strict rules. A business report can use “compared to,” and a conversation can use “in comparison with.”
5. American and British English
Both expressions are used in American and British English. There is no general rule requiring American writers to choose one and British writers to choose the other.
In either variety, clarity, sentence structure, and consistency matter more than selecting one phrase based on nationality.
How to Use Compared To and In Comparison With
Use Compared To for Direct Comparisons
Choose “compared to” when you want to describe how one thing differs from another or how it measures up against a reference point.
Examples:
- Compared to the previous version, the software is easier to use.
- My commute is shorter compared to yours.
- The company hired more employees this year compared to last year.
For especially clear writing, you can also use “than” with a comparative adjective:
- The software is easier to use than the previous version.
- My commute is shorter than yours.
The shorter constructions are often preferable when you only need to state a difference.
Use In Comparison With for Analytical Discussions
Choose “in comparison with” when you want to establish a reference point in a discussion, explanation, or report.
Examples:
- In comparison with the control group, the experimental group showed greater improvement.
- In comparison with the previous budget, the revised plan allocates more money to training.
- In comparison with other proposals, this option offers a balanced approach.
This expression is particularly useful when a paragraph examines multiple factors or develops a formal argument.
Use Either When the Meaning Is the Same
When both phrases fit the sentence naturally, choose the one that best suits your style.
For example:
- Compared to the original estimate, the final cost was lower.
- In comparison with the original estimate, the final cost was lower.
Both sentences are correct. The first is more concise, while the second provides a slightly more formal framing.
Choose a More Precise Construction When Needed
Sometimes neither expression is the clearest choice.
If you are comparing quantities, prices, or measurements, consider using “than,” “relative to,” or “compared with,” depending on the sentence.
For example:
- Less clear: In comparison with last year, the price is cheaper.
- Clearer: The price is lower than it was last year.
The revised sentence makes the relationship between the two prices explicit.
Examples
Examples of Compared To
- Compared to last week, the weather is much warmer.
- This year’s budget is smaller compared to last year’s budget.
- Compared to her classmates, Nina speaks confidently in public.
- The new phone feels lighter compared to my old phone.
- The project finished ahead of schedule compared to our original plan.
- Compared to traditional classrooms, online classes offer greater scheduling flexibility.
- Our customer satisfaction rate has improved compared to the previous quarter.
- The second candidate has more relevant experience compared to the first.
- Compared to driving, taking the train is less stressful for me.
- The town is relatively quiet compared to the nearby city.
Examples of In Comparison With
- In comparison with last week, the weather is much warmer.
- In comparison with last year’s budget, this year’s budget is smaller.
- In comparison with her classmates, Nina speaks confidently in public.
- In comparison with my old phone, the new model feels lighter.
- In comparison with our original plan, the project finished ahead of schedule.
- In comparison with traditional classrooms, online classes offer greater scheduling flexibility.
- In comparison with the previous quarter, our customer satisfaction rate has improved.
- In comparison with the first candidate, the second has more relevant experience.
- In comparison with driving, taking the train is less stressful for me.
- In comparison with the nearby city, the town is relatively quiet.
Examples in Academic and Professional Writing
Both expressions can be used in academic and professional contexts.
- Research: Compared to the control group, participants in the treatment group showed greater improvement.
- Business: In comparison with the previous quarter, revenue increased while operating costs remained stable.
- Education: Compared to the first draft, the revised essay presents a clearer argument.
- Reports: In comparison with the previous reporting period, customer complaints decreased.
- Email: The revised proposal is more affordable compared to the original estimate.
In formal writing, make sure the things being compared are genuinely comparable. For example, compare prices with prices, costs with costs, and performance with performance.
Common Mistakes
1. Assuming One Expression Is Incorrect
Incorrect assumption: “In comparison with” is grammatically wrong.
Correct understanding: Both “compared to” and “in comparison with” are accepted English expressions.
Why the mistake happens: Learners sometimes interpret differences in frequency or formality as differences in grammatical correctness.
Correct example: In comparison with last year, our sales have increased.
2. Using an Awkward or Unnecessarily Long Expression
Awkward: In comparison with the old model, the new model is better in comparison with the old model.
Better: Compared to the old model, the new model performs better.
Why the mistake happens: Writers may repeat the comparison phrase because they want to emphasize the difference.
A comparison generally needs to be stated only once unless the sentence genuinely introduces another comparison.
3. Making an Unclear Comparison
Unclear: Compared to last year, our profits are higher.
This sentence is common and understandable, but its opening phrase technically places the entire current situation alongside last year.
Clearer: Compared with last year, our profits are higher.
Also clear: Our profits are higher than they were last year.
Why the mistake happens: Writers may focus on the comparison phrase without considering the relationship between the subject and the reference point.
The clearest option often uses “than” to state the difference directly.
4. Comparing the Wrong Things
Incorrect or illogical: Compared to the previous manager, the company’s profits increased.
This sentence appears to compare the company’s profits with a person.
Correct: Compared with the previous manager’s results, the company’s profits increased.
Why the mistake happens: An introductory comparison can become misleading if the subject of the main clause does not match the intended comparison.
Make sure the reader can identify what is being compared with what.
5. Treating In Comparison With as a Verb
Incorrect: We in comparison with the two products.
Correct: We compared the two products.
Why the mistake happens: “In comparison with” and “compared with” look similar, but their grammatical functions differ.
Use compare as a verb when describing the act of examining two things. Use “in comparison with” when introducing a reference point.
6. Using a Comparison Phrase When Than Is Simpler
Wordy: The new device is faster in comparison with the old device.
Clearer: The new device is faster than the old device.
Why the mistake happens: Writers sometimes assume a longer phrase sounds more formal or precise.
In many sentences, “than” communicates the intended difference more directly.
Linguistic Insight
The expressions “compared to” and “in comparison with” illustrate how English can express a similar relationship through different grammatical structures.
1. Different Structures, Similar Meanings
“Compared to” uses the past participle compared. It belongs to a pattern in which a participial phrase introduces a reference point.
“In comparison with” uses the noun comparison within a prepositional phrase. Rather than using a participle, it frames the relationship through a noun.
Despite this structural difference, both expressions can introduce the same comparison.
2. The Meaning of Compare to and Compare With
A traditional distinction suggests that compare to emphasizes resemblance, often through a metaphor, while compare with emphasizes a direct examination of similarities and differences.
For example:
- The poet compared her smile to sunshine.
- The researcher compared the two samples with each other.
The first presents a figurative resemblance. The second describes an analytical comparison.
However, contemporary English frequently uses “compared to” for direct comparisons as well. Therefore, the distinction is a useful stylistic guideline, not an absolute rule.
3. Why Both Expressions Exist
English often offers several ways to communicate the same relationship. A participial phrase such as “compared to the previous version” can serve a similar purpose to a longer prepositional phrase such as “in comparison with the previous version.”
The choice reflects differences in sentence structure, emphasis, and style rather than a difference in basic grammatical correctness.
4. Why Learners Find Them Confusing
Learners may encounter both expressions in textbooks, articles, workplace reports, and everyday conversations. They may also encounter style guides that recommend different preferences.
The confusion increases when a traditional distinction is taught as an inflexible rule, even though actual usage allows considerable overlap.
The most reliable approach is to learn each expression’s structure, understand its function, and evaluate the complete sentence rather than judging the phrase in isolation.
Usage Tips
- Choose the shorter option when possible. “Compared to” is often a natural choice for straightforward comparisons.
- Use “in comparison with” for analytical emphasis. It works well when introducing evidence or discussing results.
- Remember that both are correct. Do not reject either phrase simply because it is less common in a particular context.
- Check the sentence’s meaning. Ensure that the two things being compared are clearly identified.
- Consider using “than.” For simple differences in price, size, speed, or quantity, “than” may produce a clearer sentence.
- Follow your style guide. Academic journals, publishers, and workplaces may have their own preferences.
- Avoid unnecessary repetition. One clear comparison is usually enough.
A simple memory aid is to think of “compared to” as the concise option and “in comparison with” as the fuller option. This is a stylistic reminder, not a strict grammar rule.
Expert Suggestion
As a grammar teacher, I recommend choosing your comparison phrase based on the sentence’s purpose rather than trying to memorize a rigid rule.
For students and English learners, practice rewriting sentences with both expressions. This helps you recognize that the core meaning often remains unchanged.
For professional writers and content creators, prioritize clarity and consistency. When comparing data or research findings, identify the exact reference point and use parallel sentence structures where possible.
For example:
- Less direct: In comparison with the previous year, the company experienced a higher rate of growth.
- More direct: The company grew faster than it did the previous year.
Both versions are grammatical, but the second communicates the comparison more efficiently.
The guiding principle is simple: use the expression that makes the relationship between the two things clearest to your reader.
Summary
“Compared to” and “in comparison with” are both correct English expressions used to explain similarities and differences between things.
- Compared to is concise and natural for direct comparisons in everyday and professional English.
- In comparison with is a slightly longer expression that often suits analytical and formal writing.
- Both expressions can be used in American and British English.
- The traditional distinction between “compared to” for resemblance and “compared with” for direct analysis is a useful guideline, but actual usage frequently overlaps.
- Neither expression is inherently incorrect. Choose according to context, sentence structure, and clarity.
When a simple comparative sentence will do, “than” may be the clearest alternative.
