Both spellings are correct, and “labelled or labeled” is a question of region, not right and wrong. “Labeled” with one l is the American standard, while “labelled” with two l’s is the standard in British, Australian and Canadian English, so pick the form your reader expects.
Key Takeaways
- Both “labeled” and “labelled” are correct spellings — neither one is a misspelling.
- “Labeled” with one l is the American English standard, and “labelled” with two l’s is the British, Australian and Canadian standard.
- Both forms mean the same thing: the past tense of “label”, to attach a tag or name to something, or to categorize it.
- British English doubles a final consonant after a single vowel before -ed and -ing; American English usually does not.
- Pick one variant and use it consistently in a document — do not mix labeled and labelled in the same piece.
Which Spelling Is Correct?
Both spellings are correct. This is one of the rare spelling questions where neither answer is wrong, because the difference is regional rather than a matter of error.
“Labeled” is the standard spelling in American English. “Labelled” is the standard spelling in British, Australian and Canadian English. A reader in New York expects one l, and a reader in London expects two — neither is looking at a mistake.
That is why spellcheckers can be misleading here. A checker set to American English will flag “labelled” as wrong, and a checker set to British English will flag “labeled” as wrong. The flag says more about the checker’s settings than about the word itself.
What Does Labeled Mean?
“Labeled” means marked with a label, or described and categorized in a particular way — the past tense and past participle of the verb “label”.
The literal sense is physical: “She labeled each jar by hand.” The figurative sense is just as common: a person can be labeled reliable, a product can be labeled organic, and a file can be labeled urgent.
The meaning is identical for “labelled”: “The bottle was labelled Poison.” says the same thing with two l’s. The spelling changes; the meaning does not.
Why Does British English Double the L?
British English doubles a final consonant after a single vowel before -ed and -ing; American English usually does not. That single pattern explains the whole difference.
In British spelling, “label” ends in one l after one vowel, so the l doubles when an ending is added: labelled and labelling. American spelling keeps one l: labeled and labeling.
The pattern shows up across the same family of verbs:
| Spelling | Region | Example | Source |
|---|---|---|---|
| labeled | American English | “She labeled each jar by hand.” | Quillbot |
| labelled | British, Australian, Canadian | “The bottle was labelled Poison.” | Grammarly |
| labeling | American English | “I am labeling the boxes now.” | Quillbot |
| labelling | British, Australian, Canadian | “He was labelling each file.” | Grammarly |
The same rule gives travelled and traveled, cancelled and canceled, modelled and modeled, and fuelled and fueled. Once the pattern is clear, the whole family of words becomes predictable.
The split is history, not logic: American spelling was simplified in the 1800s by dictionary makers who dropped doubled consonants they saw as unnecessary, while British spelling kept the older rule.
Which Form Should You Use?
Use the form your reader expects. For readers in the United States, that means “labeled” with one l.
The site’s audience is American, so “labeled” is the recommended form here. A US reader will read it as normal and will not pause over it. Using “labelled” for that same reader is not wrong, but it looks British, and it can distract from the sentence.
For readers in the UK, Australia or Canada, the advice flips: use “labelled” with two l’s, because that is what those readers expect.
When the audience is mixed or unknown, match the rest of the document. If the document already uses American spellings like “color” and “organize”, use “labeled”. If it uses “colour” and “organise”, use “labelled”. Consistency with the surrounding text matters more than either choice on its own.
Spelling guides on Activemyhouse follow the same principle: match the spelling to the reader, and keep the rest of the document in the same variety of English.
How to Stay Consistent
Consistency is the one real rule in this whole question. Pick one variant and use it in every place it appears in a document.
A short checklist makes that easy:
- Decide the audience first: American readers get “labeled”, British, Australian and Canadian readers get “labelled”.
- Set the spellchecker to match that variety before you start writing.
- Search the finished document for both forms and fix any that slipped in.
- Check the -ing forms too: labeling goes with labeled, and labelling goes with labelled.
- Apply the same variety to related words: travelled, cancelled and modelled in a British document; traveled, canceled and modeled in an American one.
A document that switches between “labeled” in one paragraph and “labelled” in the next looks careless, even though both spellings are correct. The error is not the spelling itself; it is the mixing.
What About Labelling and Labeling?
The -ing forms follow the same rule, and they are where mistakes most often appear. “Labeling” with one l is American, and “labelling” with two l’s is British. The same goes for the noun forms, such as “the labeling of the boxes” or “the labelling of the files”.
One edge case deserves a note: when writing for an international audience, pick the variety of the largest audience and stay with it. A single consistent choice reads better than a document that tries to satisfy two spellings at once.
Frequently Asked Questions

No, “labelled” is not spelled wrong. It is the standard spelling in British, Australian and Canadian English. It only looks wrong to an American spellchecker, which is set to a different variety of English.

Yes, “labeled” with one l is the American spelling. It is the standard form in the United States, and it is the recommended form for an American audience.
What is the difference between labeled and labelled?
There is no difference in meaning — only region: “labeled” is American English, “labelled” is British, Australian and Canadian English. Both mean the past tense of “label”.
Should I use labeled or labelled in the US?
Use “labeled” in the US. It is the standard American spelling, and American readers expect it. “Labelled” is correct but reads as British to an American audience.
