How Big Is a Single Bed in cm?

A UK single bed measures 90cm wide by 190cm long, and this guide explains what those centimetres mean once a bed is actually in the room. We place the single alongside every other British size, from the 75cm small single up to the 180cm super king, and show why frame dimensions always exceed mattress dimensions by five to ten centimetres. There is guidance on the smallest room a single fits, positioning under windows and sloping loft ceilings, and how much width two children sharing really need. We also cover drawer bases and cabin frames that recover floor space, why slatted bases matter in cold box rooms, how mattress depth sets the total bed height, and the strict depth limits that apply to bunk bed mattresses....
