UK Small Double Mattresses

The UK small double (120 x 190cm) gives a solo sleeper real stretching room, or fits a double bed into a room that a 4ft 6in frame would overwhelm.

Why choose a small double?

  • At 30cm wider than a single, it gives real space to anyone who sleeps alone but likes to spread out.
  • It's 15cm narrower than a standard double, so it suits box rooms and compact guest rooms.
  • Couples can share for occasional stays, making it a practical guest room choice.
  • 4ft is a standard UK size, so frames and bedding are easy to find.

Allow at least 2.4m x 2.8m; small double (4ft) fitted sheets fit, with a standard double duvet.

How big is a small double mattress?

120 x 190cm, or 4ft wide by 6ft 3in long. Some UK retailers also call it a three-quarter or queen bed.

Can two people sleep on a small double?

Yes, though it is snug: each person gets 60cm of width, less than a small single each. Fine for occasional guests, but most couples find a standard double the comfortable minimum for every night.

Who is a small double best for?

Solo sleepers who want more space than a single, and rooms where a standard double would leave too little floor space.

What bedding fits a small double?

Small double (4ft) fitted sheets. A standard double duvet (200 x 200cm) is the right size on top.

What is the difference between a small double and a double?

Width only: 120cm against 135cm. Both are 190cm long.
