Usage

ダブル functions as a noun modifier (ダブル〜) across many contexts: hotel rooms (ダブルルーム), coffee (ダブルショット), ice cream (ダブル = two scoops), and more. Note that the verb form ダブる (to overlap, to be duplicated) is a separate word with a different meaning — it refers to things overlapping or a student repeating a year.
