Mattress Size guide

Mattress dimensions should match the size of the bed frame, so keep that in mind when choosing the right mattress for you.

Small single

A small single mattress is a great option for children’s bedrooms. Since children are much smaller than adults, the 2’6 x 6’3 (75cm x 190cm) bed is the ideal size mattress and frees up more space for play.


The single bed size is 3’0 x 6’3 (90cm x 190cm), which makes it perfect for a smaller adult room.

Small double

Also known as a queen size, this double bed is a great option for a small guest bedroom. Slightly larger than a single bed, the small double mattress measures 4’0 x 6’3 (120cm x 190cm) and is a lovely space-saver.

Standard double

A common bed and mattress size in most households, the standard double bed is a popular UK bed and mattress size. Measuring 4’6 x 6’3 (135cm x 190cm),  the double bed is affordable and great for couples with a smaller bedroom.


Out of all the bed frames, king size beds are the most chosen frame for master bedrooms. Coming in at 5’0 x 6’3 (150cm x 200cm), they allow for added comfort thanks to the extra stretching room, meaning that you get the restful sleep that you need.

Super king

The largest of all the bed sizes, the super king size bed is an excellent option for large rooms where you want to make an impact. This UK bed measures a whopping 6’x 6’6 (180cm x 200cm) making it the largest of the mattress sizes.

What size should a kids bed and mattress be?
