The choice between different from vs different than is more nuanced than a simple correct-or-incorrect rule.
Both expressions describe something as not being the same. However, different from is the safest and most broadly accepted choice, especially in direct comparisons.
“My approach is different from yours.”
Different than is also established in American English. It often sounds natural when a complete clause follows:
“The experience was different than I expected.”
Sentence structure, audience, and editorial expectations can all affect the best choice.
Quick Answer
Use different from as your default, especially before a noun, pronoun, or noun phrase:
“This phone is different from my old one.”
Use different than naturally before a full clause:
“The phone was different than I thought it would be.”
You can often rewrite the sentence with from what:
“The phone was different from what I expected.”
Both forms are standard in American English, but conservative writing usually favors different from.
Why People Confuse Them
Traditional school rules often teach that only different from is acceptable. However, American speakers regularly use different than, including in carefully edited writing.
Writers also connect different from with the related verb phrase differ from:
“The two plans differ from each other.”
At the same time, than appears throughout comparative structures:
“The second plan is more expensive than the first.”
This makes both of the following patterns feel logical:
“The second plan is different from the first.”
“The result is different than we predicted.”
The disagreement is mostly about preferred style and sentence structure, not education or intelligence.
Key Differences At A Glance
| Comparison Point | Different From | Different Than |
|---|---|---|
| Core meaning | Not the same as | Not the same as |
| Status in US English | Standard | Standard |
| Safest default | Yes | Not always |
| Common following structure | Noun, pronoun, or noun phrase | Full clause |
| Before a noun phrase | Strongly preferred | Common in American usage |
| Formal-writing preference | Usually preferred | Accepted but sometimes challenged |
| Spoken American usage | Common | Common |
| Best practical use | Direct comparison | Clause or awkward alternative |
| Editorial risk | Very low | Higher with traditional readers |
| Example | “This version is different from mine.” | “It was different than I expected.” |
The forms share the same central meaning. Their main difference involves structure, convention, and editorial preference.
Meaning and Usage Difference
Different is an adjective meaning not the same, unlike, or distinct.
In different from, from normally functions as a preposition. It works especially well before nouns, pronouns, and noun phrases:
“Her answer was different from mine.”
“This design is different from the original.”
“His priorities are different from his manager’s priorities.”
In different than, than may introduce another comparison element or a complete clause:
“Her answer was different than I expected.”
“The city looks different than it did last year.”
“The project developed differently than we had planned.”
Direct comparisons usually favor different from:
“She is different from her sister.”
However, different than also occurs before noun phrases in American English:
“She is different than her sister.”
That sentence is established American usage, but different from her sister has wider editorial acceptance.
You can use different from before a nominal clause beginning with what:
“Her answer was different from what I expected.”
It also works with a how clause:
“The building looks different from how I remembered it.”
The two expressions do not have sharply different definitions. Their naturalness depends mainly on what follows them.
Tone, Context, and Formality
Different from sounds neutral in conversation, schoolwork, business communication, academic writing, and professional documents.
Formal:
“The revised policy is different from the previous policy.”
It is also the lowest-risk option for international readers and strict editorial settings.
Different than sounds natural in American conversation and can appear in professional prose:
“This place feels different than the last one.”
It often provides a clean connection before a clause:
“The outcome was different than analysts predicted.”
A conservative editor might revise that sentence to:
“The outcome was different from what analysts predicted.”
Neither version is automatically clearer in every context. Follow the publication’s required style when one exists.
The related adverb differently regularly takes than:
“The meeting went differently than we expected.”
That construction does not determine which form must follow the adjective different.
Which One Should You Use?
Use the following decision process.
When a noun, pronoun, or noun phrase follows, choose different from as the default:
“Your priorities are different from mine.”
“The new laptop is different from the older model.”
When a complete clause follows, different than often sounds natural:
“The event was different than we had imagined.”
“The neighborhood looks different than it did before.”
You may also rewrite the clause with what or how:
“The event was different from what we had imagined.”
“The neighborhood looks different from how it looked before.”
For a strict teacher, examination, editor, or publication, use different from or rewrite the sentence.
The related-verb test can also help. When differs from preserves the meaning, different from is usually a strong choice:
“Her situation differs from mine.”
“Her situation is different from mine.”
When One Choice Sounds Wrong
A mechanical substitution can produce an incomplete or malformed sentence.
Awkward:
“The movie was different from I expected.”
Natural:
“The movie was different than I expected.”
Also natural:
“The movie was different from what I expected.”
Another option is:
“The movie was different from how I expected it to be.”
Before a direct noun comparison, different than may sound controversial to traditional readers:
“Her personality is different than her sister’s.”
This is established in American usage, but the following version is safer:
“Her personality is different from her sister’s.”
Do not transfer the than pattern to the verb differ:
Incorrect:
“Her opinion differs than mine.”
Correct:
“Her opinion differs from mine.”
The phrase more different than can be correct because than follows the entire comparative phrase:
“The two results were more different than we expected.”
Common Mistakes
Mistake: Declaring “different than” universally incorrect
Overstated: “Different than is always wrong.”
Better guidance: “Different than is established in American English, particularly before clauses.”
Mistake: Using “different than” automatically
Acceptable but higher-risk: “This version is different than the original.”
Safer: “This version is different from the original.”
Mistake: Placing “different from” directly before a finite clause
Awkward: “The trip was different from we expected.”
Correct: “The trip was different than we expected.”
Correct rewrite: “The trip was different from what we expected.”
Mistake: Writing “differs than”
Incorrect: “The final version differs than the draft.”
Correct: “The final version differs from the draft.”
Mistake: Ignoring the required editorial style
Natural everyday wording: “The result was different than expected.”
Conservative alternative: “The result was different from what we expected.”
Mistake: Creating an awkward rewrite only to avoid “than”
Clear: “The event was different than I thought it would be.”
Do not replace a clear standard sentence with confusing or unnatural wording.

FAQs
Is “different than” grammatically incorrect?
No. American English has used different than for centuries, and it often works naturally before a clause: “The result was different than we expected.”
Is “different from” always the better choice?
It is the safest default, especially before nouns and pronouns. However, different than may produce a smoother sentence before a full clause.
Can “different than” be used in formal writing?
Yes, although some editors prefer different from. Follow the required house style and consider rewriting: “different from what we expected.”
Should I use “different from” before a noun?
Usually. “This version is different from the original” has broader editorial acceptance than “different than the original.”
Why is “different than I expected” acceptable?
In that structure, than introduces the comparison clause I expected. Using from requires another word: “different from what I expected.”
Is “different to” correct in American English?
American speakers may understand it, but it is chiefly associated with British usage. For US writing, choose different from or different than.
Conclusion
Both different from and different than are standard in American English. Use different from as the safest default, particularly before nouns and pronouns:
“The new version is different from the old one.”
Use different than naturally before a clause:
“The result was different than we expected.”
You can also write:
“The result was different from what we expected.”
As a memory aid, use different from wherever differs from would preserve the intended comparison.
