UK Double Mattresses

The UK double (135 x 190cm) is Britain's traditional couples' size: room to share, in a footprint that suits most bedrooms.

Why choose a double?

  • It's the long-standing UK standard for two people sharing.
  • It fits comfortably where a king would dominate the room.
  • Most mattress ranges include a double, so the choice is wide.
  • Double sheets and duvets are stocked everywhere, at every price.

Allow at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm; double sheets and a 200 x 200cm double duvet fit.

How big is a UK double mattress?

135 x 190cm, or 4ft 6in wide by 6ft 3in long.

Is a double big enough for a couple?

It works, and it's the traditional couples' size in the UK. Each person gets about 67cm of width, which is less than a single bed each, so if your room and budget stretch to a king you will notice the difference.

What size room do I need for a double bed?

As a minimum, allow around 60cm of walkway around the sides and foot of the bed: about 2.6m x 2.8m of floor space. A room of roughly 3m x 3m takes a double comfortably.

What bedding fits a double mattress?

Double fitted sheets and a double duvet (200 x 200cm).

Should I choose a double or a king?

If two of you share the bed every night and the room allows, a king adds 15cm of width and 10cm of length, usually for a modest step up in price. The double wins where space is tight.
