What Is a Small Double Bed Size?

A small double bed—often referred to as a "three-quarter bed"—is a compact yet comfortable option ideal for smaller bedrooms or guest rooms. In the UK, the standard small double bed size measures 120cm wide x 190cm long (approximately 4 feet wide x 6 feet 3 inches long).

Smaller than a standard double (135cm wide), but larger than a single (90cm), it strikes the perfect balance for solo sleepers wanting more space or for tighter layouts where a full-size double may feel overwhelming.

Small Double vs Double: What’s the Difference?

The main difference is width. A standard double bed is 15cm wider, which may not sound like much, but can make a difference in sleeping comfort for two adults. If space allows and two people will sleep in the bed regularly, consider a full double or king instead.

However, for solo use, a small double bed provides plenty of space while saving crucial floor area—perfect for rooms under 3m wide.
