Fit vs Fitted: The Quick Answer

If you’re in a hurry, use this rule:

• Use fit as the past tense in American English
• Use fitted as an adjective describing tailored clothing
• Both fit and fitted can work as past tense in British English

Examples:

• The shirt fit perfectly yesterday.
• She wore a fitted dress.
• The tailor fitted the jacket. (UK usage)

The difference comes down to grammar vs description.

What Does “Fit” Mean?

The word fit has multiple roles. It can be a verb. It can be an adjective. It can describe size, suitability, or compatibility. Context determines meaning.

“Fit” as a Present Tense Verb

When used as a verb, fit means something is the correct size or suitable. This is the most common everyday usage.

Examples:

• These shoes fit perfectly.
• The table fits in the corner.
• This plan fits our schedule.
• The key fits the lock.

Notice something important. Fit doesn’t always refer to clothing. It also applies to:

• Objects
• Plans
• Ideas
• Spaces
• Roles

This makes fit extremely flexible in English.

“Fit” as Past Tense (American English Rule)

Here’s where confusion starts. The verb fit is irregular. In American English, the past tense stays fit, not fitted.

Correct (US English):

• The jacket fit well last year.
• The lid fit tightly.
• The shoes fit perfectly yesterday.

Incorrect (US English):

• The jacket fitted well last year.

However, British English allows fitted as past tense. Both versions exist globally. That’s why you’ll see both online.

What Does “Fitted” Mean?
