Canceled and cancelled are both correct. American English usually uses one L in canceled, canceling, traveled, and labeled, while British English usually doubles it: cancelled, cancelling, travelled, and labelled. The main exception is cancellation, which has two Ls in both varieties. The form you need depends on your audience and the spelling system you follow.
Canceled or cancelled – the short answer
Use canceled with one L in American English and cancelled with two Ls in British English. The same distinction applies to canceling and cancelling. Neither form is a misspelling, but you should choose one variety of English and use it consistently.
Variety of English
Verb
Past tense
Present participle
For writing aimed at a US audience, use one L. For writing aimed at the UK or an audience that follows British spelling conventions, use two.
The real question is not “Which spelling is correct?” but “Which spelling is right for my audience?”
Why canceled has one L and cancelled has two
The difference comes from how American and British English apply the rule for doubling a final L before suffixes such as -ed and -ing.
British English usually doubles a final L when it follows a single vowel, even when the final syllable is not stressed. That is why travel becomes travelled, cancel becomes cancelled, and model becomes modelled.
American English generally doubles the final L only when the stress falls on the last syllable. Because travel, cancel, and model are stressed on the first syllable, American English usually keeps one L.
That's why these words behave differently:
Word
Stress
American
British
Notice the bottom three: compelled, controlled, propelled are spelled the same everywhere, because the stress is on the final syllable and both rules agree. It's only the first-syllable-stressed words where American and British part ways.
Why cancellation always has two Ls
Cancellation is spelled with two Ls in both American and British English. An American writer therefore uses canceled with one L but cancellation with two, even when both words appear in the same sentence.
The noun follows a separate established spelling pattern from the -ed and -ing forms:
The airline canceled the flight because of bad weather. Passengers received a cancellation notice later that evening.
The two spellings may look inconsistent, but both are standard.
This is the main exception to remember: the noun cancellation keeps two Ls in every variety of English.
The wider family: words that double the L
The cancel/travel pattern extends across many everyday words. For quick reference:
American (one L)
British (two Ls)
In every pair, the word is stressed on an earlier syllable, so British doubles the L and American doesn't.
Words with two Ls in American English and one in British English
A smaller group follows the opposite pattern. In these words, American English uses two Ls where British English commonly uses one.
British (one L)
American (two Ls)
Here British English drops an L that American English keeps. It's the mirror image of cancel, and it catches people who assume “British always doubles.” It doesn't – it depends on where the L sits in the word.
Which spelling should you use?
Choose the spelling that matches your audience, publication, organisation, or required style guide. Neither canceled nor cancelled is universally more correct, but mixing spelling systems in the same document can look inconsistent.
Common situations include:
Writing for a US company or publication? Use American spelling throughout – *canceled*, *traveled*, *labeled*.
Writing for a UK, European, or Commonwealth audience? Use British spelling – *cancelled*, *travelled*, *labelled*.
Writing for an international audience? British spelling is more widely used globally, but consistency matters more than the choice itself.
Preparing for an English exam? Check which variety the exam expects – Cambridge and most UK exams expect British; US-based tests expect American.
The most important rule is simple: pick one variety and stay with it. Using traveled in one paragraph and cancelled in the next is more distracting than choosing either system consistently.

How to check whether a word doubles the L
To check whether an English word needs one L or two, look it up in a dictionary that labels British and American spellings separately. This lets you see whether the forms differ, whether both are accepted, and which one matches the English you are using.
Oxford Dictionary, built by MobiSystems, presents British and American forms so you can compare spellings such as canceled and cancelled or traveled and travelled without relying on memory.

Frequently asked questions
Both spellings are correct. Canceled with one L is the standard American English form, while cancelled with two Ls is standard in British English and in many places that follow British spelling conventions. Choose the form that matches your audience and use it consistently.
British English usually doubles a final L before a suffix such as -ed or -ing when the word ends in a single vowel followed by L. This applies even when the final syllable is unstressed, so cancel becomes cancelled and cancelling.
American English generally doubles the L only when the final syllable is stressed, which is why it uses canceled and canceling.
Cancellation is spelled with two Ls in both American and British English. Although American English uses canceled with one L, the related noun still keeps both: cancellation.
It is the main exception worth remembering.
Canceled is standard in the United States, while cancelled is used in the UK and in many countries and organisations that follow British spelling conventions. There is no single worldwide standard, so the best choice depends on your audience, location, or style guide.
It matters more that you match your audience and remain consistent than whether you choose the American or British form. Neither spelling is wrong, but switching between the two systems in the same piece of writing can look like an editing mistake.
Yes. Oxford Dictionary shows British and American spelling differences, helping you identify which form belongs to each variety of English. It can also help you check related words, definitions, usage examples, and pronunciation when the two varieties differ.
The bottom line
Canceled and cancelled are both correct. American English uses one L, while British English uses two. The same pattern applies to words such as traveled/travelled and labeled/labelled, although cancellation keeps two Ls in both varieties.
Learn the general rule, remember the main exception, and use one spelling system consistently. When you are unsure, a dictionary that shows both British and American forms can settle the question quickly.
