Quick answer: Use compared to when highlighting similarities between fundamentally different things (e.g., “She compared his voice to thunder”). Use compared with when juxtaposing two similar things to analyze both their similarities and differences (e.g., “Compared with last year’s revenue, this year’s is higher”). While you might search for a compared to or with synonym to vary your writing, mastering this specific distinction is the hallmark of polished, professional prose.
Writers frequently stumble over whether to use “compared to” or “compared with” in formal documents, resumes, and academic papers. The confusion stems from the fact that both phrases involve evaluating two items side by side, leading many to search for a generic compared to or with synonym rather than learning the actual grammatical rule. The human brain naturally seeks patterns, and because both phrases begin with “compared,” we default to the more common “to” out of habit. This cognitive shortcut is exactly what copy editors are trained to catch. In my decade of experience as a veteran copy editor, I have seen this subtle error undermine otherwise stellar cover letters, weaken data-driven business reports, and create unintentional ambiguity in academic manuscripts. Mastering this distinction is not just about pedantic rule-following; it is about ensuring your reader instantly grasps whether you are drawing a poetic metaphor or conducting a rigorous, side-by-side analysis. When you get this right, your writing sharpens in precision, authority, and meticulous attention to detail.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Compared to | Used to highlight similarities or liken two fundamentally different things. | “The editor compared the manuscript’s pacing to a runaway train.” |
| Compared with | Used to juxtapose two similar things to examine both their similarities and differences. | “Compared with the Q3 report, the Q4 earnings show a 15% increase.” |
When to use compared to
Rule: Use “compared to” when you are asserting a likeness or metaphorical similarity between two things that are not in the same category. This phrase is your go-to tool for figurative language, analogies, and illustrative examples. While you might be tempted to look for a compared to or with synonym to avoid repetition, precision here matters far more than variety. According to Synonym, a synonym is a word or phrase that means exactly or nearly the same as another, but in grammar, choosing the correct comparative phrase prevents logical confusion. If you swap these terms carelessly, you risk making your metaphors sound like flawed data analysis. If you write “Compared with a breath of fresh air,” you inadvertently imply that the policy and the fresh air are two measurable entities on the same spectrum, which sounds absurd. Precision in metaphorical language ensures your reader stays immersed in your message rather than stumbling over a logical hiccup.
- Email error: “Compared with a breath of fresh air, this new policy is welcome.”
- Email fix: “Compared to a breath of fresh air, this new policy is welcome.” (A corporate policy and fresh air are fundamentally different categories; you are highlighting a metaphorical similarity, not measuring air quality).
- Resume error: “Compared with a well-oiled machine, I streamlined the department’s workflow.”
- Resume fix: “Compared to a well-oiled machine, I streamlined the department’s workflow.” (You are likening your workflow to a machine to emphasize efficiency, not statistically analyzing two separate machines).
- Text message error: “This movie was boring, I’d compare it with watching paint dry.”
- Text message fix: “This movie was boring; I’d compare it to watching paint dry.” (You are drawing a vivid, relatable analogy about the passage of time).
- Cover letter error: “Compared with a seasoned navigator, I can guide your team through this merger.”
- Cover letter fix: “Compared to a seasoned navigator, I can guide your team through this merger.” (You are establishing a metaphorical role for yourself, not claiming you are literally a ship’s captain).
When to use compared with
Rule: Use “compared with” when you are placing two items of the same class or category side by side to weigh their specific differences and similarities. This is the language of data analysis, performance reviews, and objective evaluation. The cultural resonance of the phrase “compared to what?” reminds us that any comparison must have a logical anchor to be meaningful. According to Compared to What, this famous 1960s protest song title highlights how demanding a clear baseline is essential for any valid critique or evaluation. In professional writing, “compared with” provides that exact baseline, signaling to your reader that a direct, apples-to-apples assessment is underway. In data-driven fields like finance, marketing, or science, using “compared to” for a direct analysis can subconsciously signal to a meticulous reader that the writer is not detail-oriented. Using “compared with” demonstrates that you understand the rigorous nature of the data you are presenting.
- Email error: “Compared to the Q3 budget, our Q4 spending is down 10%.”
- Email fix: “Compared with the Q3 budget, our Q4 spending is down 10%.” (You are juxtaposing two similar financial periods to analyze a specific, measurable difference).
- Resume error: “Compared to my previous role, this position requires advanced data modeling.”
- Resume fix: “Compared with my previous role, this position requires advanced data modeling skills.” (You are weighing two similar professional experiences to highlight a specific skill gap or growth area).
- Text message error: “Compared to your old phone, this new model has a much better battery.”
- Text message fix: “Compared with your old phone, this new model has a much better battery.” (Two phones are being directly evaluated against each other on specific hardware metrics).
- Performance review error: “Compared to last year’s metrics, your customer retention has improved.”
- Performance review fix: “Compared with last year’s metrics, your customer retention has improved.” (You are conducting a direct, period-over-period business analysis).
How to remember the difference
Memory trick: The “O” and “W” rule.
- ComparEd tO is for Outside categories (metaphors and likening different things).
- ComparEd With is for Weighing similar things (analyzing two items in the same category).
Editor’s insight: Beyond the mnemonic, I teach my clients a simple substitution test. If you can seamlessly replace the phrase with “likened to,” use “compared to.” If you can replace it with “measured against” or “evaluated alongside,” use “compared with.” This quick mental swap prevents 99% of the errors I see in client manuscripts. For example, you would say “likened to a runaway train” (so, compared to), but you would say “measured against last year’s budget” (so, compared with). This trick works universally across all forms of professional writing and requires no memorization of complex grammatical terminology.
Common mistakes and exceptions
The most frequent mistake I see is using “compared to” for statistical or direct analysis, which makes the writing feel slightly informal, imprecise, or even careless. For example, “Compared to last year, sales are up” is widely tolerated in casual business writing or quick Slack messages. However, “Compared with last year, sales are up” is the technically correct choice for formal reports, investor decks, and academic papers where precision is non-negotiable.
Another common exception involves the phrase “in comparison to” versus “in comparison with.” These follow the exact same grammatical rules: use “in comparison to” for metaphors and “in comparison with” for direct juxtaposition. Writers often mistakenly believe that adding “in” changes the rule, but it does not. The underlying logic of category matching remains identical.
Note on US vs. UK English: Both American and British style guides (including the Chicago Manual of Style, AP Stylebook, and Oxford Style Manual) uphold this distinction. Historically, the rule was taught more rigidly in British English, while American English has shown more flexibility. However, modern usage trends show “compared to” increasingly swallowing “compared with” in casual contexts across the globe. As a professional writer or editor, holding the line on “compared with” for direct analysis signals strong editorial control and respect for your reader’s intelligence.
One final edge case: When the comparison is passive or inverted, the rule still applies. For instance, “The new software, when compared with the legacy system, offers superior security.” The proximity of the words does not change the fundamental need for “with” when evaluating two similar systems. Furthermore, this specific distinction is frequently tested on standardized exams like the GMAT and SAT. Test-makers deliberately include “compared to” as a trap answer in sentences that clearly require a direct, analytical juxtaposition, knowing that untrained writers will select it out of habit.
Frequently Asked Questions
Is “compared to” ever correct for similar items? In casual, everyday speech, yes, most readers will not consciously notice the error. However, in formal writing, resumes, or professional emails, you should strictly use “compared with” when analyzing two similar items side by side to maintain absolute precision and professional credibility.
Can I just use a synonym instead of worrying about this rule? While finding a compared to or with synonym like “versus,” “against,” or “relative to” can work in some contexts, it often subtly changes the nuance or tone of the sentence. Mastering the correct comparative phrase is always safer, more elegant, and more precise than guessing a substitute that might not fit the grammatical structure.
What about the phrase “as compared to”? “As compared to” is generally considered wordy, clunky, and redundant by professional editors. It is almost always better to simply delete the “as” and use “compared to” or “compared with,” depending on the rule above, to make your sentences tighter and more impactful.
Does this rule apply to the noun form “comparison”? Yes, the underlying logic remains identical. You typically make a “comparison of” two things or a “comparison between” two items. However, when using the verb form in a sentence, the “to” versus “with” distinction remains the primary mechanism for maintaining logical clarity and preventing reader confusion.
