What’s a Standard Double Bed Size?
A standard double bed in Britain measures 135 cm wide by 190 cm long, or 4 ft 6 in by 6 ft 3 in, and it remains the most widely bought size in the country. This guide explains where the double sits between the 120 cm small double and the 150 cm king, how much sleeping width each person actually gets when two adults share, and why the fixed 190 cm length is the specification taller sleepers should check first. We also cover how much extra floor space a frame adds beyond the mattress footprint, the walkways a double needs to feel comfortable in a typical British bedroom, the correct duvet and pillowcase sizes, and practical storage choices that protect the space you have left around the bed. There is guidance too on the centre support and slat spacing a double frame needs, and the access checks worth making before you order....
