# Emperor Size Bed

> An Emperor bed in UK shops usually means a square mattress of 200 by 200 cm, often called 6ft 6. It sits above the UK Super King of 180 × 200 cm. Emperor is a marketing size, not a regulated British Standard, so some makers differ. Check sheet availability, frame strength and delivery access.

**Definition.** An Emperor bed in UK shops usually means a 200 × 200 cm mattress. It is a marketing size, not a British Standard.

Also called: emperor bed, 6ft 6 bed, emperor mattress.

Always confirm the centimetres with the maker before buying sheets or a frame.

Ask whether the mattress comes in two halves for easier delivery up stairs.
