A bed is only the right bed if it's the right size — for you, your partner and your room. This guide covers every standard UK bed size with exact dimensions, who each size suits, and the measuring checks to do before you order.

How to choose the right size
Measure the room first. Allow at least 60cm of walking space on each open side of the bed and at the foot. For an ottoman bed, remember the storage lid needs clearance to open — end-lift designs need free space at the foot of the bed.
Think about length as well as width. King and super king beds are 10cm longer than doubles (200cm vs 190cm) — worth knowing if anyone in the bed is over 6ft tall.
Couples: bigger is usually better. A double gives each person about 67cm of width — less than a single bed each. If the room allows it, a king size is the single biggest comfort upgrade most couples can make.
Do UK sizes match EU and US sizes?
No — they're close but not interchangeable. A UK king (150×200cm) sits between a US queen and US king, and EU sizes run longer than UK equivalents. Always buy a mattress in the same sizing standard as your bed frame.
