Commensurate With or To uses the standard preposition with when you describe a matching degree, amount, or quality in English. The word commensurate works as an adjective meaning proportionate or equivalent in size, amount, quality, degree, or importance. Writers sometimes hesitate between commensurate with and commensurate to, but the usual construction is commensurate with.
English dictionaries, including Oxford and Cambridge, show this pattern, while commensurate with something appears as a formal collocation. In my experience with English learning and formal writing, this standard and established choice makes a difficult prepositional puzzle easier to understand. The modern English pattern gives you a clear path when the right preposition feels uncertain.
The pattern works in an email, article, report, résumé, academic paper, business document, or standard English text. “Her salary is commensurate with her experience” means her pay matches her level of experience. You can also show correspondence between value and importance, quality, or amount with this construction. Dictionaries, modern dictionary sources, and historical dictionaries provide useful context for historical usage and current meanings. Some people may use commensurate to, yet commensurate with remains the safer option for natural English and correct English. This simple signpost can help prevent a wrong choice that weakens your message. The details, nuances, and confusion surrounding these tricky pairs can seem perplexing, but clear guidance removes much of the dilemma.
Quick Answer: Is It “Commensurate With” or “Commensurate To”?
Commensurate with is the standard expression in modern English.
Use commensurate with when you mean that something appropriately corresponds to another thing in amount, quality, size, degree, importance, or level.
The salary should be commensurate with your experience.
The response should be commensurate with the level of risk.
The punishment should be commensurate with the offense.
Oxford lists commensurate (with something) as the standard pattern and defines it as matching something in size, importance, quality, and similar measures.
Commensurate to can be found in English, particularly in older or less common usage. Collins also records to as an alternative in its dictionary entry. Still, commensurate with is the construction to choose when you want the clearest standard usage.
| Expression | Standard modern usage | Example |
| commensurate with | Yes | The salary is commensurate with experience. |
| commensurate to | Less common | The salary is commensurate to experience. |
| proportionate to | Yes | The response was proportionate to the risk. |
| equivalent to | Yes | The amount is equivalent to the original cost. |
The easiest rule is simple: use “commensurate with.”
What Does “Commensurate With” Mean?
Commensurate with means appropriately matching or corresponding to something else.
The comparison doesn’t necessarily mean that two things are exactly equal. Instead, it suggests that their degree, size, amount, quality, importance, or value is suitably related.
For example:
The salary is commensurate with her experience.
This means her salary appropriately reflects her experience. It doesn’t necessarily mean that her years of experience and her salary have a mathematically exact relationship.
Cambridge defines commensurate as being suitable in amount or quality compared with something else. Its American definition also describes the word as matching in degree.
Simple Definition of Commensurate
In plain English, commensurate can often mean:
- matching
- corresponding
- proportionate
- appropriate in relation to something
- suitable in amount or degree
- comparable in level
For example:
The workload increased without a commensurate increase in staff.
Here, the sentence suggests that the staff should have increased appropriately as the workload grew.
That relationship is the heart of the word.
Why Is “Commensurate With” the Standard Phrase?
The reason becomes clearer when you look at how dictionaries present the word.
Oxford gives the construction commensurate with something and defines it as matching something in size, importance, or quality. Cambridge likewise lists commensurate with something as a formal collocation and provides examples involving salary, duties, wages, service, and policy.
A Canadian government language resource states the rule directly: “The adjective commensurate uses the preposition with.”
So, while English has historical variation, modern standard usage strongly favors commensurate with.
The Basic Grammar Pattern
The most common structure looks like this:
Subject + be + commensurate with + noun or noun phrase
Examples:
- The salary is commensurate with experience.
- The benefits are commensurate with the position.
- The punishment was commensurate with the offense.
- The response should be commensurate with the threat.
- The resources were commensurate with the project’s scope.
You can also use commensurate directly before a noun:
The company provided a commensurate increase in staffing.
Here, commensurate means appropriately corresponding to something already mentioned or understood from context.
“Commensurate With” Meaning in Different Contexts
The phrase becomes easier to understand when you see how widely it applies.
Salary and Compensation
This is probably the most familiar context.
Job advertisements frequently describe compensation as being commensurate with experience. Cambridge itself uses this pattern in its definition.
The company offers a salary commensurate with your qualifications and experience.
The phrase means that the compensation should reflect the person’s relevant background, skills, or responsibilities.
You might also see:
- pay commensurate with experience
- compensation commensurate with qualifications
- wages commensurate with responsibilities
- benefits commensurate with seniority
Effort and Results
The phrase can also describe a relationship between effort and an outcome.
The reward should be commensurate with the effort required.
This doesn’t promise a fixed mathematical ratio. Instead, it suggests that the reward should reasonably correspond to the amount or difficulty of the effort.
Risk and Response
Businesses, governments, and organizations often use commensurate with when discussing risk.
The security measures should be commensurate with the level of risk.
The idea is straightforward: a minor risk might call for modest precautions, while a serious risk may justify stronger measures.
Punishment and Offense
The expression also appears in legal and disciplinary contexts.
The penalty should be commensurate with the seriousness of the violation.
Again, the meaning isn’t necessarily “exactly equal.” It means the consequence should correspond appropriately to the seriousness of the action.
Responsibility and Authority
Workplace writing often uses the phrase to connect responsibilities with compensation, authority, or resources.
Her compensation should be commensurate with the responsibilities of the position.
The underlying idea is balance. Greater responsibility may reasonably call for a corresponding level of compensation or authority.
Is “Commensurate To” Correct?
This question needs a little more nuance than a simple yes-or-no answer.
Commensurate to does occur in English. It isn’t an invented expression. Historical dictionary evidence includes examples using to, and Collins lists to as an alternative preposition in its entry for commensurate.
However, that doesn’t make both constructions equally common or equally useful in modern standard writing.
Oxford’s American dictionary gives commensurate with something as the established pattern. Cambridge does the same.
Therefore, if you’re choosing between the two today, commensurate with is the better default.
Why You May See “Commensurate To”
One reason for the variation may be interference from other expressions.
English commonly uses:
- proportionate to
- equivalent to
- equal to
- relative to
- corresponding to
Because these expressions use to, writers may naturally produce commensurate to by analogy.
There’s also a historical reason. Older English sources contain examples of commensurate to, including an 1828 American dictionary example.
That historical evidence matters because it shows that to isn’t simply a modern typo. Nevertheless, modern usage favors with strongly enough that writers should normally use the established form.
Commensurate With vs. Proportionate To
This is one of the most useful comparisons to remember.
Both expressions describe a relationship between two things. The prepositions simply differ.
The salary is commensurate with experience.
The salary is proportionate to experience.
Both sentences can communicate a similar idea.
| Word | Usual construction | Example |
| commensurate | with | Pay is commensurate with experience. |
| proportionate | to | Pay is proportionate to experience. |
| equivalent | to | The amount is equivalent to the original cost. |
| consistent | with | The evidence is consistent with the findings. |
| corresponding | to | The increase corresponds to the demand. |
This difference explains why commensurate to can feel tempting. English doesn’t use one universal preposition for every word that describes comparison or correspondence.
The solution isn’t to follow the meaning alone. Learn the established collocation.
Commensurate With vs. Commensurate To: Key Difference
The main difference is usage and standardness, not a reliable difference in meaning.
Consider these sentences:
The salary is commensurate with her experience.
The salary is commensurate to her experience.
A reader can understand both. The first sentence follows the standard dictionary pattern and sounds more natural in contemporary formal English.
The second sentence may appear in actual writing, especially in older or less common usage. But it isn’t the construction most style-conscious writers would choose.
Less Preferred vs. Standard Examples
| Less common construction | Standard construction |
| The salary is commensurate to experience. | The salary is commensurate with experience. |
| The penalty was commensurate to the offense. | The penalty was commensurate with the offense. |
| The response was commensurate to the threat. | The response was commensurate with the threat. |
| Benefits should be commensurate to responsibilities. | Benefits should be commensurate with responsibilities. |
| Resources must be commensurate to the project’s scope. | Resources must be commensurate with the project’s scope. |
When there’s no special historical or stylistic reason to preserve to, changing it to with is usually the cleanest choice.
How to Use “Commensurate With” in a Sentence
Once you understand the pattern, using it becomes straightforward.
Commensurate With + Noun
The simplest structure places a noun after with.
The reward was commensurate with the effort.
The penalty was commensurate with the violation.
The salary is commensurate with experience.
Commensurate With + Noun Phrase
You can also follow with with a longer noun phrase.
The response should be commensurate with the seriousness of the situation.
The resources should be commensurate with the project’s long-term requirements.
This construction works well when the comparison needs more detail.
Be Commensurate With
The phrase frequently appears with forms of be:
- is commensurate with
- are commensurate with
- was commensurate with
- were commensurate with
- should be commensurate with
- must be commensurate with
- needs to be commensurate with
For example:
The compensation should be commensurate with the employee’s responsibilities.
The resources must be commensurate with the project’s scale.
Salary Is Commensurate With Experience
This particular pattern deserves attention because it appears so often in employment writing.
Salary is commensurate with experience.
It means that the employer intends to determine or adjust compensation according to the candidate’s relevant experience.
You might also encounter:
Compensation is commensurate with qualifications and experience.
The starting salary will be commensurate with relevant experience.
The position offers benefits commensurate with seniority.
Oxford specifically uses “Salary will be commensurate with experience” as an example of the standard construction.
15 Examples of “Commensurate With”
Here are practical examples across several contexts:
- The salary should be commensurate with your experience.
- The reward was commensurate with the effort required.
- The penalty should be commensurate with the offense.
- The response must be commensurate with the level of risk.
- Her authority was commensurate with her responsibilities.
- The benefits were commensurate with the position.
- The price should be commensurate with the product’s quality.
- Staffing levels should be commensurate with the workload.
- The investment should be commensurate with the expected return.
- The resources weren’t commensurate with the project’s scope.
- The training requirements were commensurate with the job’s demands.
- The compensation was commensurate with the employee’s qualifications.
- The response wasn’t commensurate with the seriousness of the problem.
- The fee should be commensurate with the service provided.
- The level of oversight should be commensurate with the potential risk.
Notice the recurring idea: one thing corresponds appropriately to another.
Common Mistakes With “Commensurate”
Using “To” Automatically
The biggest mistake is assuming that commensurate works like proportionate.
You might remember:
proportionate to
Then write:
commensurate to
But the established modern pattern is:
commensurate with
That small preposition makes a noticeable difference in polished writing.
Confusing “Commensurate With” and “Commensurate To”
The two constructions can communicate essentially the same relationship. However, commensurate with is much more firmly established in contemporary standard usage.
If you’re unsure, don’t overthink it.
Choose “with.”
Misunderstanding the Meaning
Another mistake is treating commensurate as a strict synonym for equal.
That’s too narrow.
Cambridge explains the word in terms of being suitable in amount or quality compared with something else and also describes it as matching in degree.
For example:
The resources are commensurate with the project’s needs.
This doesn’t necessarily mean the resources and needs have identical numerical values. It means the resources are suitably matched to those needs.
Using “Commensurate” When a Simpler Word Works Better
Commensurate is useful, but it has a distinctly formal tone. Both Cambridge and Oxford label the adjective as formal.
Sometimes a simpler phrase sounds better.
Instead of:
The compensation should be commensurate with your contribution.
You could write:
The compensation should match your contribution.
Or:
The compensation should be proportionate to your contribution.
The best choice depends on your audience.
Synonyms for “Commensurate With”
No synonym fits every sentence perfectly. Still, these alternatives can help you avoid repetition.
| Alternative | Typical meaning |
| proportionate to | Corresponding in size or degree |
| corresponding to | Matching or relating to something |
| matching | Being equal or suitably similar |
| equivalent to | Having the same value or effect |
| in keeping with | Suitable or consistent with |
| consistent with | Agreeing with or not conflicting with |
| appropriate to | Suitable for a particular situation |
| in proportion to | Increasing or decreasing relative to something |
For example:
The response should be commensurate with the risk.
Could become:
The response should be proportionate to the risk.
Both work. The second may sound slightly more direct.
Commensurate With in Formal and Professional Writing
Commensurate with has a strong place in professional English because it expresses a relationship precisely without requiring a long explanation.
You’ll commonly encounter it in:
- Job advertisements
- Business reports
- Contracts
- Academic writing
- Government documents
- Legal writing
- Corporate policies
- Professional evaluations
Cambridge’s examples include salary, duties, wages, service charges, and government policy.
That range shows how flexible the phrase can be.
A Workplace Example
Imagine an employee takes on twice as many responsibilities but receives no corresponding increase in compensation or authority.
A formal report might say:
The employee’s compensation is not commensurate with the expanded scope of the role.
A simpler version would be:
The employee’s compensation doesn’t match the expanded role.
Both are grammatical. The first sounds more formal and analytical.
A Practical Case Study: Salary and Experience
Consider two job advertisements.
Advertisement A:
Salary commensurate with experience.
Advertisement B:
Salary commensurate to experience.
The first follows the standard dictionary construction. Oxford gives almost exactly this pattern as its example.
The second is understandable and has historical and dictionary evidence behind the broader use of to. However, it isn’t the form most modern professional writers should default to.
This distinction matters because grammar isn’t always a simple question of “possible” versus “impossible.” Some constructions exist in real English but remain less conventional than others.
How to Remember “Commensurate With”
A simple memory trick can save you from the confusion:
Commensurate goes with “with.”
Think of with as connecting two things that belong together.
- salary with experience
- duties with rank
- response with risk
- penalty with offense
- resources with needs
Oxford and Cambridge both support this standard pattern.
If you’re writing under pressure, that one rule is usually enough.
Commensurate With or To? At-a-Glance Comparison
| Feature | Commensurate With | Commensurate To |
| Standard modern pattern | Yes | Less common |
| Meaning | Matching or corresponding appropriately | Generally conveys the same basic relationship |
| Found in dictionaries | Yes | Yes, in some sources |
| Common professional choice | Yes | Less common |
| Common in formal writing | Yes | Much less common |
| Best default for modern writing | Yes | Usually replace with with |
| Example | Salary is commensurate with experience. | Salary is commensurate to experience. |
The important distinction is that commensurate to isn’t simply meaningless or impossible. Historical and modern dictionary evidence demonstrates that it exists.
Still, standard contemporary references overwhelmingly present commensurate with as the normal construction.

FAQs:
Is “commensurate with” grammatically correct?
Yes. Commensurate with is the standard construction used in modern English. Oxford and Cambridge both give commensurate with something as the normal pattern.
Is “commensurate to” grammatically correct?
Commensurate to appears in English, including historical usage, and some modern dictionaries acknowledge to as an alternative. However, commensurate with is the stronger default for contemporary standard writing.
What does “commensurate with” mean?
It means matching or corresponding appropriately to something in size, amount, quality, importance, or degree.
For example:
The salary is commensurate with experience.
The salary is intended to reflect the person’s relevant experience.
Should I say “salary commensurate with experience”?
Yes. Salary commensurate with experience is a standard professional expression. Oxford uses essentially this exact construction in its dictionary example.
What is another way to say “commensurate with”?
Depending on context, you can use proportionate to, matching, corresponding to, equivalent to, appropriate to, or in keeping with.
However, these alternatives aren’t always interchangeable. Choose one based on the exact relationship you’re describing.
Is “commensurate with” formal?
Yes. Major dictionaries classify commensurate as a formal adjective.
It’s especially common in professional, legal, academic, corporate, and administrative writing.
Is “commensurate” the same as “equal”?
Not always. Commensurate usually means appropriately corresponding in size, amount, quality, importance, or degree. It can imply proportion rather than exact numerical equality.
Conclusion:
When choosing between commensurate with or to, use commensurate with in standard English. It means that something matches or corresponds appropriately to another thing. For example, you can say, “The salary is commensurate with experience.” Although commensurate to appears in some sources, commensurate with is the more common and accepted choice in modern writing.
