What Are the Measurements of a Small Double Bed?
A small double bed measures 120cm wide by 190cm long, which is 4ft by 6ft 3in, or 48 inches by 75 inches. It is the size UK retailers also list as a three quarter bed, and it exists for a very practical reason: plenty of British bedrooms are too narrow for a standard double but too generous for a single. This guide gives the exact measurements, the frame allowances to expect once side rails and headboards are included, the bedding that actually fits, and honest guidance on which rooms genuinely benefit from the size. We also cover room layout and clearance figures, storage choices for tight spaces, base support and slat spacing, mattress depth and sheet fit, and the access checks worth doing before delivery day. The aim is simple: the bed you order should work in the room you actually have. Every measurement below is given in UK retail terms, so the numbers match what you will see....
