Quick answer: Use “compared to” when highlighting similarities between different things (often metaphorical), and use “compared with” when examining both similarities and differences for analytical purposes. In modern usage, “compared to” is more common and widely accepted for most situations.
These two phrases trip up even experienced writers because the distinction feels subtle and, honestly, most native speakers use them interchangeably without consequence. However, if you’re writing formally—academic papers, professional reports, or polished manuscripts—knowing the difference separates careful writers from careless ones. I’ve corrected this exact error countless times in cover letters and published articles, and once you understand the rule, you’ll spot it everywhere.
Comparison Table: Compared To vs. Compared With
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Compared to | Used to suggest likeness or similarity between different things; often metaphorical or poetic | “She compared his voice to velvet.” |
| Compared with | Used to examine similarities AND differences; analytical, side-by-side comparison | “Compared with last year’s figures, profits are down 12%.” |
When to use “compared to”
The rule: Use “compared to” when you’re pointing out resemblances between things that are fundamentally different, especially in metaphorical or figurative language. This is the phrase poets, novelists, and romantic writers reach for because it emphasizes similarity rather than analysis.
Think of “compared to” as the phrase for creative, imaginative comparisons. When Shakespeare wrote “Shall I compare thee to a summer’s day?” he wasn’t conducting a statistical analysis of his beloved versus meteorological data—he was celebrating similarity and beauty.
Real-world examples:
Error in an email: “My new job is stressful compared with a roller coaster.”
Fix: “My new job is stressful compared to a roller coaster.” (You’re highlighting similarity between two different things—a job and an amusement ride—not analyzing them side by side.)Error in a wedding toast: “Your love is steady compared with a lighthouse.”
Fix: “Your love is steady compared to a lighthouse.” (This is metaphorical; you’re drawing a poetic parallel, not conducting an analytical comparison.)Error in a LinkedIn bio: “My approach to leadership is collaborative compared with a symphony orchestra.”
Fix: “My approach to leadership is collaborative compared to a symphony orchestra.” (You’re suggesting likeness between leadership style and musical ensemble, not measuring them against each other.)
According to the Wikipedia entry on “Compared to What”, the very title of this famous song highlights how comparison requires a reference point—when we say something is “compared to” something else, we’re establishing that reference to illuminate similarity.
When to use “compared with”
The rule: Use “compared with” when you’re placing two similar things side by side to examine both their similarities and differences, typically in analytical, scientific, or statistical contexts. This is the phrase researchers, data analysts, and business professionals use when they need precision.
“Compared with” signals that you’re doing serious evaluation work. You’re not just saying two things are alike—you’re measuring them against each other to draw conclusions about performance, quality, quantity, or effectiveness.
Real-world examples:
Error in a resume: “Increased sales by 40% compared to the previous quarter.”
Fix: “Increased sales by 40% compared with the previous quarter.” (You’re presenting measurable data and analyzing performance across two time periods—this is analytical, not metaphorical.)Error in a research paper: “The treatment group showed improvement compared to the control group.”
Fix: “The treatment group showed improvement compared with the control group.” (This is scientific comparison examining differences between two similar groups.)Error in a business report: “Our customer satisfaction scores are higher compared to our main competitor.”
Fix: “Our customer satisfaction scores are higher compared with our main competitor.” (You’re conducting competitive analysis, measuring similar metrics across similar entities.)
The distinction matters because “compared with” invites scrutiny. When you use it, you’re telling your reader: “I’ve examined these things carefully, and here’s what I found.” It’s the phrase of accountability and precision.
How to remember the difference
Here’s the memory trick I teach every junior editor I mentor: “To” is for poetry, “With” is for work.
If you’re writing something creative, emotional, or imaginative—use “compared to.” If you’re writing something analytical, professional, or data-driven—use “compared with.”
Another way to think about it:
- “Compared to” = You’re saying Thing A is like Thing B (similarity focus)
- “Compared with” = You’re measuring Thing A against Thing B (analysis focus)
Try this test: Replace your comparison phrase with “like.” If it sounds natural, use “compared to.” If it sounds wrong or too casual, use “compared with.”
- “She compared his voice like velvet” → Sounds natural → “compared to” ✓
- “Profits are down like last year” → Sounds wrong → “compared with” ✓
Common mistakes and exceptions
The biggest mistake: Assuming the distinction matters in casual conversation. It doesn’t. If you’re texting a friend or writing a social media post, use whichever sounds natural. Native speakers swap these constantly, and nobody cares.
The exception that breaks the rule: When the comparison is passive (using “compared” as a participle), many style guides now accept both interchangeably. For example:
- “Compared to last year, we’re doing better.” ✓
- “Compared with last year, we’re doing better.” ✓
Both work here because the sentence structure is different—you’re not actively comparing; you’re describing a state of comparison.
US vs. UK differences: There’s no significant regional variation here. Both American and British English recognize the distinction, though both also accept casual interchangeability. The Chicago Manual of Style, AP Stylebook, and Oxford Style Manual all acknowledge the traditional difference while noting that strict adherence isn’t always necessary.
When you MUST be precise: Academic writing, scientific publications, legal documents, and formal business reports. In these contexts, reviewers and editors will catch “compared to” when you mean “compared with,” and it undermines your credibility. I once saw a graduate student’s thesis delayed because their committee flagged inconsistent comparison language throughout 200 pages.
The modern reality: Language evolves, and “compared to” is increasingly used for all purposes. Major publications like The New York Times and The Guardian use “compared to” even in analytical contexts. If you’re writing for the web or general audiences, “compared to” is safer because it’s more familiar to readers.
However—and this is crucial—if you’re writing for an audience that values precision (academics, scientists, lawyers, senior executives), use the traditional distinction. It signals that you respect their standards.
Frequently Asked Questions
Can I always just use “compared to” and be safe?
In casual writing and most modern contexts, yes. “Compared to” is more common and widely accepted. However, in formal academic or scientific writing, using “compared with” for analytical comparisons shows greater precision and may be expected by your audience.
Is “compared against” a valid alternative?
Yes, “compared against” works well when you’re emphasizing opposition or contrast, particularly in technical or competitive contexts. For example: “The algorithm was tested compared against three industry standards.” It’s slightly more forceful than “compared with.”
What about “in comparison to” versus “in comparison with”?
The same rules apply. “In comparison to” suggests similarity (often metaphorical), while “in comparison with” suggests analytical examination. However, these phrases are even more interchangeable than “compared to/with,” and the distinction matters less.
Why do some grammar guides say the difference doesn’t matter?
Because language is descriptive, not prescriptive. While traditional grammar distinguishes between the two, actual usage shows significant overlap. Major style guides now acknowledge that the distinction is subtle and that consistency within a document matters more than rigid adherence to the rule.
Understanding the meaning of words requires looking at both their historical usage and their current application—and in this case, both phrases have legitimate places in modern English.
