You typed the word, and you stopped. Something about it didn’t feel correct. You deleted it, retyped it, and still weren’t sure. That momentary pause is more common than you might think. One word trips up writers, students, and even professional editors regularly. The good news is that both spellings are right. The real question is not which is correct. It’s a matter of which is right for you.
Both spellings come from the verb “label,” which means to mark, tag, or identify something. When you label a box, you’re writing what’s inside it. When you label an idea, you’re categorizing it.
“Labelled” and “labeled” are simply the past tense forms of that same verb. Neither spelling changes the meaning. A shirt described as “labeled organic cotton” means the same thing as one described as “labelled organic cotton.” The confusion isn’t about meaning at all. It’s about geography.
A Quick Example
Imagine two shipping departments, one in Chicago and one in London, packing identical boxes.
The Chicago team writes: “All boxes have been labeled and are ready to ship.”
The London team writes: “All boxes have been labelled and are ready to ship.”
Same task. Same result. Different spelling, based purely on where each team learned English.
The Real Difference: American vs British English
This comes down to a spelling pattern, not a grammar rule. English has several verbs that double their final consonant in British English but not in American English, especially when adding endings like “-ed” or “-ing.”
“Label” fits that exact pattern.

American English tends to keep spelling simpler and drops the second “l.” British English tends to preserve the doubled consonant, following older spelling conventions.
You’ll see the same pattern in other words, like “traveled/travelled” and “canceled/cancelled.” If you’ve ever wondered why your spell checker flags one of those, this is why.
How to Use “Labeled” Correctly (US English)
“Labeled” is the standard spelling across the United States. You’ll see it in American newspapers, textbooks, business writing, and everyday conversation.
When to Use It
Use “labeled” when:
You’re writing for a US-based audience.
Your company style guide follows American English.
You’re publishing on a platform that defaults to US spelling, like most American blogs or SEO content.
Example Sentences
“The samples were labeled by batch number before testing began.”
“Each folder is labeled with the client’s name for quick reference.”
“She labeled the leftovers so nobody would mix them up.”
Notice the pattern. One “l” before the ending, every time.
How to Use “Labelled” Correctly (UK English)
“Labelled” is the accepted spelling throughout the United Kingdom, as well as in Australia, Canada (in many contexts), and other regions that follow British English conventions.
When to Use It
Use “labelled” when:
You’re writing for a UK, Australian, or broader Commonwealth audience.
Your publication or company follows British English style.
You’re editing academic or formal writing intended for international, UK-based readers.
Example Sentences
“The ingredients were labelled clearly on the packaging.”
“Every wire was labelled before the electrician left the site.”
“The museum labelled each artifact with its country of origin.”
The extra “l” isn’t a typo. It’s the expected form in this variety of English.
Labeling vs Labelling: Same Rule Applies
The spelling pattern doesn’t stop at past tense. It carries over to the present participle form as well.
American English: labeling
British English: labelling
This trips people up constantly, because writers often get the past tense right but forget to apply the same rule to “-ing” forms. If you’re writing “labeled” in American English, stay consistent and use “labeling,” not “labelling,” later in the same document.
The same logic applies in reverse for British English writers.
Which Spelling Should You Use?
The honest answer: it depends on your audience, not on which spelling is “more correct.”
Ask Yourself These Questions
Who is reading this? If most of your readers are in the US, go with “labeled.” If they’re primarily in the UK, Australia, or another British English region, use “labelled.”
Does your organization have a style guide? Many companies specify a preferred English variety. Follow that guide over personal preference.
Are you writing for global SEO? If your audience is mixed, check which spelling gets more search volume for your specific market, then stay consistent throughout the piece.
The One Rule That Always Applies
Whichever spelling you choose, don’t mix the two in the same document. Switching between “labeled” and “labelled” partway through an article looks like a careless mistake, even though both spellings are technically correct on their own.
Pick one. Stick with it. Let your audience’s location guide the decision.
Common Mistakes and Exceptions
A few patterns confuse even among experienced writers.
Mixing different spellings in one document. This is the most common mistake of all. Having an article with both “labeled” and “labelled” is just sloppy writing, even if the majority of people wouldn’t be able to tell the difference.
Assuming that the default setting on a spellchecker is always correct. If you are writing an article for a British audience, but your spellchecker is set to American English, it will flag many correctly spelled British English words as wrong.
Forgetting to change the –ing ending. Writers will often forget to change the –ing ending if they are only thinking about the –ed ending. If you change ‘labeled’ to ‘labelled,’ you should also change ‘labeling’ to ‘labelling.’
Overzealous editing. If you have multiple people editing the same document, it can be easy to have some change spellings, and others change them back. You should always run a consistency check before publishing any document.
Assuming one spelling is more professional than the other. Neither ‘labelled’ nor ‘labeled’ is more professional than the other, but they are both used in different dialects of English.
