Modeled or Modelled: Which Spelling Is Correct?

Modeled is the standard spelling in American English, while modelled is the usual spelling in British English. Both forms come from the verb model and have the same meaning. The extra l is simply a regional spelling difference, so your choice should match the variety of English you are using.

Quick Answer

Use modeled for American English and modelled for British English. Both are correct. The related forms are modeling in American English and modelling in British English.

Modeled vs. Modelled

What Do Modeled and Modelled Mean?

Both forms are the past tense and past participle of model. Depending on context, the verb can mean creating something based on a model, copying a design, or demonstrating how something should be done.

An architect may have modeled a building after an older design, while a teacher may have modelled a behavior for students.

The meaning stays the same; only the spelling changes.

Why Are the Spellings Different?

The difference comes from American and British spelling conventions, especially the treatment of the final l before -ed and -ing.

American English:
model → modeled → modeling

British English:
model → modelled → modelling

American English normally keeps one l, while British English doubles it. The same pattern appears in traveled/travelled, labeled/labelled, and canceled/cancelled.

When to Use Each Spelling

Use modeled when writing in American English or for a US audience. Common phrases include modeled after, modeled behavior, and modeled a process.

Use modelled when following British English conventions. The same phrases can appear as modelled after, modelled behavior, and modelled a process.

For related forms, keep the same regional pattern:

American English: modeled, modeling
British English: modelled, modelling

Common Mistakes

Mixing the two forms

Both spellings are correct, but switching between modeled and modelled in one article can make the writing look inconsistent.

Assuming one spelling is wrong

Neither form is universally incorrect. The right choice depends on the variety of English.

Forgetting the related form

The same difference appears in modeling/modelling, so the present participle should match your chosen style.

Pronunciation

Modeled and modelled are pronounced the same way in standard English. The extra l changes the spelling, not the pronunciation.
