How Wide Is a Double Bed in cm?
A double bed in the UK is 135 cm wide and 190 cm long, which converts to 4 ft 6 in by 6 ft 3 in. This guide explains where that width sits within the British range, from the 90 cm single through to the 180 cm super king, and why the frame always takes up more floor space than the mattress specification suggests. We look at what 135 cm means in practice for two sleepers, which is roughly 67.5 cm each and narrower than a single mattress, along with the imperial conversions that cause confusion and the occasional 137 cm listing. There is also guidance on room widths and walkways, matching bedding sizes and sheet depths, how frame style changes the footprint, and the two signals that suggest moving up to a king.
