The Bed And Mattress Size Guide
In the UK, bed sizes are measured according to the size of the mattress they hold, which is a standard measurement. Most modern mattresses sold in the UK (and Ireland) are constructed using imperial dimensions but are generally sold in their approximate metric equivalents:

What size is a single mattress?
Suitable for both children and adults. A single mattress measures in at 90cm wide and 190cm long. In imperial dimensions, this is equal to 3 feet wide and 6 feet 3 inches long. Single (3’0”) mattresses are wider than ‘small singles’ and provide a good amount of room for a single sleeper. This is the most common size for children’s beds, including bunk beds. For growing children, a single mattress can account for any growth spurts, from toddler right up through to teenage years.
Best for: 1 person
What size is a small double (queen) mattress?
In metric dimensions, a small double mattress is 120cm wide and 190cm long. This equals to 4 feet wide and 6 feet 3 inches long. A ‘small double’ (4’0”) mattress (also known as a ‘Queen’ or a ‘Three Quarter’) is wider than a single mattress but smaller in width than a double. It provides plenty of space for one or enough room for two (although two adults may find it a little ‘cosy’). Great for smaller bedrooms and guestrooms where a standard double won’t quite fit.
Best for: 1 person and small bedrooms
What size is a double mattress?
Measured in metric units, a standard double mattress is 135cm wide and 190cm long. Converted to imperial units, this equates to 4 feet 6 inches wide and 6 feet 3 inches long. A standard double mattress (4’6”) is designed to sleep two adults comfortably. This is the most common and widely available size for all bed types in the UK.
Best for: Comfortably fit 2 people and for small to average sized bedrooms
What size is a king size mattress?
Measured in metric units, a king size mattress is 150cm wide and 200cm long. Converted to imperial units, a king size bed and mattress is 5 feet wide and 6 feet 6 inches long. A standard ‘King Size’ (5’0”) mattress includes a longer length than the standard ‘double’ mattress - 6’6” instead of 6’3”. A king size mattress will provide plenty of room for two adult sleepers, but is ideal for larger bedrooms with more space available.
Best for: 2 people wanting that extra space and those people taller than 190cm
