Commensurate With or To? Which Is the Correct Preposition? explains the correct preposition choice and why commensurate with is preferred in English. The phrase commensurate with is the preferred and standard expression in formal English when showing that something is equal, proportional, or appropriately matched with another thing. Many English learners and native speakers find the commensurate with and commensurate to phrases confusing because both appear grammatically possible.
However, the correct preposition is with, and this commonly used form appears in professional writing, academic communication, contracts, and workplace discussions. The meaning of this phrase explains a clear relationship, correspondence, and equivalence between two things. For example, “Her salary is commensurate with her experience” shows that the salary is matched, balanced, and proportional to her skills and background.
When discussing grammatical usage, writers should understand that choosing the right preposition can make or break sentences because these small words have the power to change meanings. The difference between commensurate with and commensurate to creates a common dilemma during the language learning journey. In modern English, commensurate with usage is the accepted usage, while commensurate to usage sounds less natural. Strong grammar skills, clear writing tips, and proper sentence formation help improve communication skills, writing skills, and overall language accuracy. Writers should focus on context, word choice, sentence structure, and correct grammar to create natural English, effective professional communication, and better English usage.

What Does “Commensurate” Mean?
The adjective commensurate means equal in measure, proportion, size, importance, or degree. It describes two things that appropriately match each other.
In simple terms, something is commensurate when it is fair, proportional, or suitable compared to something else.
Plain-English Definition
If one thing is commensurate with another, they match in value, amount, or significance.
For example:
- Higher responsibilities should come with commensurate pay.
- The punishment should be commensurate with the offense.
- Rewards should be commensurate with effort.
In each example, one thing appropriately matches the other.
Origin of the Word
The word commensurate comes from the Latin commensuratus, meaning having a common measure.
Breaking it down:
- Com- = together
- Mensura = measure
That historical meaning explains why the word still refers to things being measured fairly against each other.
Why “Commensurate With” Is Grammatically Correct
English contains thousands of adjective-preposition combinations that have become standard through centuries of usage.
Just as we naturally say:
- interested in
- capable of
- responsible for
- familiar with
we also say:
- commensurate with
This isn’t simply a grammar rule. It’s an established collocation, meaning native speakers consistently pair these words together.
Because dictionaries, universities, legal documents, government publications, and business writing overwhelmingly use commensurate with, it has become the accepted standard.
Think of It This Way
The word with suggests comparison or correspondence.
That perfectly matches the meaning of commensurate, which compares one thing against another.
Is “Commensurate To” Ever Correct?
This is where many writers become confused.
Technically, commensurate to appears in some books, online articles, and older publications. However, frequency alone does not make an expression standard.
Modern grammar references almost always recommend commensurate with instead.
Why Does “Commensurate To” Exist?
Several reasons explain its occasional appearance:
- Writers confuse it with expressions like equal to.
- Some regional writing habits influenced its use.
- Older texts sometimes used different prepositional patterns.
- Informal online writing often spreads nonstandard combinations.
Should You Ever Use It?
If you’re writing:
- academic papers
- resumes
- business emails
- legal documents
- professional reports
- research articles
always choose commensurate with.
It sounds more natural and reflects current standard English.
Commensurate With vs. Commensurate To
| Feature | Commensurate With | Commensurate To |
| Standard English | ✅ Yes | ❌ Generally No |
| Dictionary preference | ✅ Yes | Rare |
| Academic writing | ✅ Preferred | Not recommended |
| Business communication | ✅ Preferred | Avoid |
| Legal writing | ✅ Standard | Rare |
| Natural to native speakers | ✅ Yes | Less natural |
| Common in job advertisements | ✅ Very common | Rare |
The comparison makes one conclusion clear: commensurate with is the expression you should use.
