Bed sizes in the UK

It's often difficult to figure out what size bed and mattress is best for your family. For a bed with two people sleeping in it is it better to get a double or a king? Is double too small? Why not a super king? Should you get a single or a small double for your child?

Usually it's recommended to get the biggest size of bed for a particular room. However, we think it's important to use past experience to figure out which size bed to buy. In general people are more disappointed by getting a bed that is too small rather than too large. It's important to leave at least 2 feet on all sides of the bed so that navigating your room is not too difficult. All doors and drawers near the location of your bed should also be measured to make sure they don't collide.

It is important to note that any time a shop speaks of the size of the bed it is safe to assume it is actually the size of the mattress. The physical size of the bed frame will usually be slightly larger. For example a UK king size bed frame which is 5'0" x 6'6" accommodates a mattress of that size and the actual frame is larger.

What size is a Small double bed (also known as a 4ft bed or a queen bed)?

The EU 120cm x 190cm, EU 120cm x 200cm or UK Small double bed (4'0" x 6'3") is suited for young adults and single adults with a small room. It can also be used for children. While two people can sleep in a small double in a pinch, it will not be comfortable and is not recommended for a long term arrangement.

Sometimes a small double bed is also referred to as a 4ft bed as this is the size of mattress that fits on a small double bed. A queen sized bed may also refer to a small double size. However, the queen size mattress is not a standard in UK. If buying a queen size bed frame or queen mattress we recommend UK customers double check that their bed and mattress work together.
