The Definitive Advice Guide to UK Bed Sizes

Confused about Bed Sizes?

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

Choosing the right bed and mattress size is one of the most important decisions you can make when updating your bedroom. It is important to remember that bed and mattress sizes can differ between countries. It is also important to check the size of bed frames before buying as these will vary depending on the type of bed. But for standard dimensions, here are the most accurate UK bed and mattress sizes:

Super King Bed Size

What measurements is a super king size bed and mattress?

Standard super king beds and mattresses are 180 centimetres wide and 200 centimetres long. In imperial dimensions, this equals 6 feet in width and 6 feet 6 inches in length.

As the largest bed and mattress size available, especially if you have children — you can expect the children to want to climb into bed at some point. It’s the rules!

King size beds are also excellent options if your partner is a bit of a wriggler and disturbs you with their movements at night!

Recommended for: 2 persons and those who value space.

King Size Bed

King Size Bed Measurements.

What measurements is a king size bed and mattress?

In metric dimensions, a standard king size bed and mattress is 150cm wide and 200cm long. This is equal to 5 feet wide and 6 feet 6 inches long in imperial measurements.

Queen size is an American term for kingsize beds and is slightly smaller than the UK size, 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.

It is also worth noting that on some websites, the term ‘wide double beds’, is a Japanese equivalent of the king size bed.

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.

Recommended for: 2 persons and tall people.

Double Bed Size

Double Bed Size.

What measurements is a double bed and mattress?

A standard double bed and mattress are 135cm wide and 190cm. In imperial dimensions, this is equal to 4 feet 6 inches wide and 6 feet 3 inches long.

A standard double is a useful choice for couples although it can be quite cosy. If you like more room then an upgrade to a kingsize bed or larger would be recommended providing you have space.

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.

However, in the UK, it is actually smaller than a standard double bed.

Remember in this guide measurements are the UK standard bed measurements, avoiding confusion.

Recommended for: 2 persons and a small to the average-sized bedroom.
