UK bed sizes run from a toddler bed at 70 x 140cm to a super king at 180 x 200cm. The four everyday sizes are the single (90 x 190cm), double (135 x 190cm), king (150 x 200cm) and super king (180 x 200cm). Every size is below in centimetres, feet and inches, with who it suits and the room it needs.
These are mattress sizes. A bed frame is always bigger than the mattress it holds, so measure your room against the frame size on the product page, not the name of the size.

UK bed size chart
| Size | Mattress size | Feet and inches | Sleeps |
|---|---|---|---|
| Toddler or cot bed | 70 x 140cm | 2ft 3in x 4ft 7in | One small child |
| Shorty | 75 x 175cm (some junior beds take 70 x 160cm) | 2ft 6in x 5ft 9in | One younger child |
| Small single | 75 x 190cm | 2ft 6in x 6ft 3in | One child or teenager |
| Single | 90 x 190cm | 3ft x 6ft 3in | One child, teenager or adult |
| European single | 90 x 200cm | 3ft x 6ft 6in | One taller sleeper |

| European small double | 120 x 200cm | 4ft x 6ft 6in | One taller adult |
| Double | 135 x 190cm | 4ft 6in x 6ft 3in | Two adults |
| European double | 140 x 200cm | 4ft 7in x 6ft 6in | Two adults |
| King | 150 x 200cm | 5ft x 6ft 6in | Two adults, with more room |
| Super king | 180 x 200cm | 6ft x 6ft 6in | Two adults, with the most room |
Width comes first, then length. The feet and inches are the traditional names and they're rounded (200cm is nearer 6ft 7in than 6ft 6in), so measure in centimetres.
The frame is bigger than the mattress. Our Henley Solid Oak Bed shows by how much. The single takes a 90 x 190cm mattress and the frame is 103cm wide and 200cm long. The king takes a 150 x 200cm mattress and the frame is 164cm wide and 209cm long.
Toddler, shorty and small single
Toddler or cot bed, 70 x 140cm. The first bed after the cot, low to the floor and small enough for the tightest room. Our Toddler Bed with Safety Rails, White, Pink or Gruffalo is 144cm long and 74cm wide.
See toddler beds and kids' mattresses, or read the toddler bed size guide.
- Shorty, 75 x 175cm. The common UK shorty mattress is 15cm narrower and 15cm shorter than a single, for a younger child in a small room. If your frame takes that size, see shorty mattresses. Shorty isn't one fixed size, though. Our own shorty beds take a smaller 70 x 160cm mattress, and the size is on each product page.
- Small single, 75 x 190cm. As long as a single and 15cm narrower. Some cabin beds, trundles and narrow frames take it, so check the product page. See small single mattresses.
Our kids' bed size guide compares the children's sizes in more depth.
Single and European single
- Single, 90 x 190cm. The standard bed for one person, from a child's first full-size bed to a teenager's room or a guest room. It suits a box room, with one side against the wall. See single beds and single mattresses, or the single bed size guide.
- European single, 90 x 200cm. The same width with 10cm more length. It's common on beds made in Europe and suits taller teenagers and adults. See European single beds and European single mattresses.
Small double and double
- Small double, 120 x 190cm. Also called a 4ft or three-quarter bed. It's roomy for one and snug for two, at 60cm each, so it suits a teenager or a guest room too small for a double. See small double beds and small double mattresses, or the small double bed guide.
- European small double, 120 x 200cm. The same width, 10cm longer. See European small double mattresses.
- Double, 135 x 190cm. The usual choice for two adults, with 67.5cm each, and it fits most main bedrooms. See double beds and double mattresses, or the double bed size guide.
- European double, 140 x 200cm. 5cm wider and 10cm longer than a UK double, so the two aren't interchangeable. See European double mattresses.
King and super king
King, 150 x 200cm. 15cm wider and 10cm longer than a double, which gives two adults 75cm each and more legroom for anyone tall. Allow about 3m of wall. See king size beds and king size mattresses.
Super king, 180 x 200cm. The biggest standard UK size, with 90cm each, the width of a single bed. It needs a large main bedroom. See super king beds and super king mattresses.
The Sloane Ottoman Bed shown comes in single, double, king and super king. Our king size bed dimensions guide has real frame sizes for both.
What about queen size?
Queen isn't a standard UK bed size. When a UK shop says queen it usually means a small double, 120 x 190cm, and the National Bed Federation's Bed Advice guide lists queen as another name for that size. In the United States a queen is 60 x 80 inches, about 152 x 203cm, which is closest to a UK king. If a bed or bedding is labelled queen, go by the centimetres.
What you gain with each size up
| Moving from | Extra width | Extra length | Width each for two |
|---|---|---|---|
| Single to small double | 30cm | None | 60cm |
| Small double to double | 15cm | None | 67.5cm |
| Double to king | 15cm | 10cm | 75cm |
| King to super king | 30cm | None | 90cm |
Will it fit my room?
Take the frame size from the product page and add walking space. As a rule of thumb, allow about 70cm wherever you need to walk: one side and the foot for a bed against a wall, both sides and the foot for a bed two people share. These examples use real frames.
| Bed | Frame, width x length | Floor to allow |
|---|---|---|
| Single | 100 x 202cm | About 1.7 x 2.7m |
| Small double | 128 x 202cm | About 2 x 2.7m |
| Double | 145 x 202cm | About 2.9 x 2.7m |
| King | 160 x 212cm | About 3 x 2.8m |
| Super king | 198 x 213cm | About 3.4 x 2.8m |
The first four are our Simple Pine Bed Frame, Single to King, and the super king is the Sloane Ottoman Bed. The single and small double figures assume one side against a wall. Mark the frame out with masking tape, and check that doors and drawers still open. If storage is the squeeze, ottoman beds keep bedding under the mattress.
Choosing the mattress size
Match the mattress to the bed, not the name. Every product page gives the mattress size the bed takes. UK and European sizes aren't interchangeable: a 190cm mattress in a 200cm frame leaves a 10cm gap at the end. Our PocketBalance Mattress comes in single, small double, double, king and super king.
Browse all mattresses and mattress protectors, or see our UK mattress sizes guide. For a bunk bed, high sleeper or trundle, read the kids' mattress guide first, because depth matters as well as size.
