Queen-size names a bed — and the sheets, blankets, and mattress that fit it — made for two people, larger than a standard double (or “full”) bed and smaller than a king-size bed. Shops use it as a size label, the way they use small and large for clothes. Nobody means “a bed for a queen.” It is everyday American shopping language that has spread; you will hear it in furniture stores and on packaging. People also write queen size as two words, and they talk about a queen-size bed or queen-size sheets.

加大雙人（床、床單尺寸）。賣場也常直接說 queen size；比雙人小一號的是標準雙人，再大一號才是特大／king size。
