How Wide Are Bed Sizes?

UK bed widths run from 90cm for a single to 180cm for a super king, with a small double at 120cm, a double at 135cm and a king at 150cm in between. Width does almost all the work in deciding what fits a British bedroom, because length only varies between 190cm and 200cm across the entire range. This guide sets out every width in centimetres and feet, then divides each one to show what two sleepers actually get. It explains why frame width always exceeds mattress width, sometimes by 15cm on an upholstered design, and gives the full room width needed for one and two walkways at every size. It also covers how leg height, headboard proportion and bedding tone change perceived width in a small room....

What Are Bed Widths?

UK bed widths run from 75cm for a small single through single at 90cm, small double at 120cm, double at 135cm, king at 150cm and super king at 180cm. This guide sets out every standard size with its length, then translates each width into space per sleeper so you can judge what will actually feel comfortable. We explain the gap between mattress width and real frame footprint, which is where most bedroom planning mistakes begin, and match each width to realistic room dimensions including bedside furniture allowances. There is also detail on the correct duvet and fitted sheet size for every width, how access and stair turns become harder as beds get wider, and which width suits master bedrooms, second bedrooms, box rooms, children's rooms and loft conversions....

What Are the Widths of Beds?

Standard UK bed widths run in five steps: 90cm for a single, 120cm for a small double, 135cm for a double, 150cm for a king size and 180cm for a super king. Below those sit cot beds at around 70cm and short singles that share the 90cm width but lose length. This guide sets out every width in centimetres and feet, explains why length matters just as much, and shows how the shared 190cm length of singles, small doubles and doubles compares with the 200cm length of king frames. It also covers the clearances to leave around a bed, the masking tape test that reveals awkward layouts, which duvet and fitted sheet sizes pair with each width, and the access checks that stop a bed arriving too wide for the stairs. There is a section on imported widths such as queen, Emperor and Continental sizes, plus advice on planning wardrobes and drawers around the width you choose....
