Sizeable or Sizable Quick Answer

Both mean fairly large, considerable, or substantial.

Both sentences are correct.
If you are writing for an American audience, sizable is usually the better choice. For British English, sizeable is generally preferred.
The Origin of Sizeable or Sizable
Both sizeable and sizable come from the noun size. The word size has a long history and ultimately comes from Old French sise, referring to an established measure or amount.
The adjective sizeable developed from size with the suffix -able, meaning something that can be described by the base word.
The spelling difference developed because English spelling has never been completely standardized across all English-speaking regions.
American English often favors shorter or simplified spellings, while British English sometimes retains forms that include additional letters.
In this case, American English commonly uses sizable, dropping the second e from sizeable. British English generally keeps the e, giving us sizeable.
Importantly, this is a spelling difference rather than a difference in meaning. Both forms describe something that is fairly large or significant.
