1. Thinking One Spelling Is Incorrect

Incorrect belief: Sizeable is always wrong.

Correct: Both sizable and sizeable are accepted spellings.

2. Using Both Spellings Inconsistently

Try not to switch between sizable and sizeable in the same article or document without a reason.

For example, if you choose American English, use sizable consistently. If you choose British English, use sizeable consistently, unless a required style guide specifies otherwise.

3. Confusing the Word with “Size”

Although sizeable contains the word size, it does not simply mean that something has a measurable size. It usually means that the size, amount, or effect is considerable.

Both spellings generally mean fairly large or considerable. They do not necessarily mean enormous.

For example, a sizable donation may be large compared with typical donations, even if it is not the largest donation ever made.
