Curb or Kerb: Which Is Correct?

Updated 2026-10-03 · Which One Is Correct editorial team

Quick answer: The short answer is that both curb and kerb are correct, but they belong to different dialects of English. Curb is the standard spelling in the United States and Canada, while kerb is the preferred form in the United Kingdom and other Commonwealth countries.

The Short Answer

Both curb and kerb are correct spellings, but they serve distinct regional purposes in the English language. You should use curb if you are writing for an American audience and kerb if you are targeting British readers.

People often confuse these terms because they sound identical and refer to the exact same physical object, which is the raised edge of a sidewalk. The difference is purely orthographic, stemming from historical spelling variations that never fully converged into a single global standard.
