A Short Guide to Bed Sizes

Have you ever wondered what the difference is between a kingsize bed, a queen and a double? Not quite sure what mattresses correspond to which size bed? This is a short guide to bed sizes in the UK so you can clear up the confusion and choose the bed that works best for you.


There are two types of single bed: small singles, which are 75 x 190 cms in size, and standard singles, which are 90 x 190 cm in size. Small single beds are pretty much the same as standard single ones but are a little bit narrower. If you’re trying to get a young child to transition from a toddler’s bed to a normal bed, a small single is ideal. Single beds are suitable for children and adults.

There are other reasons, besides transitioning, why you might choose a single bed. It could be going in a small room, possibly in a guest room. Perhaps the bed is for a slightly older child and you want something that will last. A single bed can solve the problem and will continue to serve a child from their younger years and into their teens.


There are two main types of double beds: small doubles, which are 120 x 190 cm in size, and standard doubles, which are 135 x 190 cm in size. A standard double is a useful choice for couples and can be quite cosy, but if both partners like to spread out they may prefer to upgrade to a kingsize bed or larger. 

Now, this is where things start to get confusing. You may see a small double bed referred to as a ‘queen bed’ and some think this is somewhere between a standard double bed and a kingsize one. Not in the UK. It’s actually smaller than a standard double bed. Small doubles are helpful for couples but may be better for single adults who want plenty of space or for teens, especially if you don’t have much space in your bedroom.


Kingsize beds are 150 x 200 cm in size, but you may see a lot of companies refer to them as ‘queen’ beds. This is the American term for kingsize beds, so if you happen to be dealing with a US retailer or are browsing on a US website, be aware of this use of the term. On some sites, you might see the term ‘wide double beds’, a Japanese equivalent of king size.

Kingsize beds are one of the more luxurious options and are especially suitable for couples. This popular bed option spoils each partner with plenty of space. The extra length of a kingsize bed also makes these beds an inviting option for taller people. Of course, if you buy a king size bed, you’ll need a reasonably large bedroom.

Super kingsize

If you really fancy lots and lots of space, you can order a super kingsize bed, which is a whopping 180 x 200 cm in size. Just like standard king sized beds, these won’t fit in a small bedroom and they’re superb for couples, especially if you have children — you can expect the children to want to climb into bed at some point. It’s the rules! Kingsize beds are also excellent options if your partner is a bit of a wriggler and disturbs you with their movements at night!

Note that upgrading to a larger bed isn’t as expensive as you might expect. Now that you have an idea of the different terms for the beds and the sizes of mattress that fit on them, you could treat yourself and go for something a bit more grand.
