Have you ever stopped while writing and wondered whether to use sizable or sizeable? You’re not alone.
The words mean the same thing, but the spelling changes based on region.
Many writers worry about choosing the wrong version, especially in business or academic writing.
This guide gives you a quick answer and explains when to use each spelling with confidence.
Sizable or Sizeable – Quick Answer
Both sizable and sizeable are correct.
- Sizable is the American English spelling.
- Sizeable is the British English spelling.
They mean the same thing: large in size, amount, or importance.
Examples:
- The company made a sizable profit this year. (American English)
- The company made a sizeable profit this year. (British English)
There is no difference in meaning. Only the spelling changes based on region.
The Origin of Sizable or Sizeable
The word comes from size, which entered English from Old French assise, meaning “a fixed amount” or “measurement.”
Over time, English speakers added the suffix:
- -able (American preference)
- -eable (British preference in some words)
In early English writing, spelling was not fixed. Many words had several variations. As dictionaries became standard in the 18th and 19th centuries, spelling rules began to split between British and American English.
Noah Webster, who shaped American English spelling, preferred simpler forms. He often removed extra letters. That is why American English uses:
- color (not colour)
- favor (not favour)
- sizable (not sizeable)
British English kept many older spellings, including forms like sizeable.
Both forms have existed for centuries. Today, each is correct in its own regional context.
British English vs American English Spelling
The difference between sizable and sizeable follows a larger spelling pattern.
American English often drops the extra “e” in certain adjective forms.
Examples of Similar Differences:
| American English | British English |
|---|---|
| sizable | sizeable |
| sizable profit | sizeable profit |
| likable | likeable |
| usable | useable |
| sizable growth | sizeable growth |
Notice something important:
Not all words follow the same rule. For example:
- manageable (same in both)
- changeable (same in both)
English is not always fully consistent. That is why checking your audience matters.

|---|---|---|
| Meaning | Large | Large |

Both are professional. The choice depends on your audience.
Which Spelling Should You Use?
Choosing between sizable or sizeable depends on who is reading your writing.
If Your Audience Is in the United States:
Use sizable.
It matches American spelling rules and looks natural to US readers.
If Your Audience Is in the UK or Commonwealth Countries:
Use sizeable.
Countries like the UK, Australia, New Zealand, and Canada often prefer British spelling.
If Your Audience Is Global:
Choose one style and stay consistent.
Many global companies prefer American English because it is widely used online. However, consistency is more important than the specific choice.
Switching between sizable and sizeable in the same article can look careless.
Common Mistakes with Sizable or Sizeable
Here are frequent errors writers make:
1. Mixing Both Spellings in One Document
