noun which may take the genitive case particle 'no', na-adjective
fairly wide; quite large; relatively spacious
Describes something as being on the wider or more spacious side, often implying a moderate degree rather than extreme width. Used attributively with の or as a na-adjective.
この部屋は広めなので、家具をたくさん置ける。
This room is fairly spacious, so we can put a lot of furniture in it.
広めのズボンを買った。
I bought pants that are on the wider side.
広い means 'wide' or 'spacious' as a simple adjective. 広め adds the nuance of 'somewhat' or 'relatively', indicating a moderate degree.
Formed from the adjective stem 広 (hiro) + the suffix め (me), which indicates a tendency or moderate degree. The kanji 広目 is a less common variant.
