The width of a single bed in the UK is 90cm. Paired with a 190cm length, that gives the standard single mattress footprint used across British bedding, mattresses and bed frames. In imperial terms it is described as 3ft, and both labels refer to the same bed.<\/p>\n
Alongside the standard single sits the small single at 75cm wide, made for genuinely narrow rooms, and the long single at 90cm by 200cm for taller sleepers. Everything else described as a single in the UK will be 90cm across.<\/p>\n
Bed listings quote two different sets of measurements and they are easy to confuse. The bed size refers to the mattress that fits the frame. The product dimensions refer to the outer edges of the frame itself, including side rails, feet and any upholstered padding.<\/p>\n
A single frame described as 90cm might have an external width of 96cm in a slim metal design or 104cm in a deeply padded fabric design. When you are working with a fixed alcove or a gap between two pieces of furniture, the external figure is the one that decides whether the bed fits.<\/p>\n
Height figures are worth reading too. Headboard height affects how the bed looks against a window or a sloping ceiling, and base height determines how easy the bed is to get in and out of.<\/p>\n
Housing stock across the UK includes a large number of third bedrooms under 7 square metres. In rooms of that size, the difference between a 95cm frame and a 105cm frame changes the layout entirely. Ten centimetres can decide whether a wardrobe door opens fully or whether a chest of drawers sits flush against the wall.<\/p>\n
Chimney breasts, boxed in pipework and stair bulkheads all reduce usable wall length in ways a floor plan rarely shows. Measure the wall you intend to place the bed against at three heights: at the skirting, at mattress level and at headboard level. Older properties frequently vary by several centimetres across those three points.<\/p>\n
The standard single at 90cm by 190cm suits the widest range of rooms and has the best availability of bedding and mattresses. It works for children, teenagers and adults, and it is the size guest rooms are usually built around.<\/p>\n
The small single at 75cm by 190cm saves 15cm of width. That is genuinely useful in a room where a standard single would block a doorway, but bedding choice is narrower and resale appeal is lower. It suits younger children better than adults.<\/p>\n
The long single at 90cm by 200cm keeps the same width but adds 10cm of length, which helps anyone over about six feet tall. Check that the extra length still leaves a walkway at the foot of the bed before choosing it.<\/p>\n
Start with the total room dimensions, then subtract the bed footprint and the access space you need. A single bed against a long wall in a 2.2m wide room leaves roughly 1.15m of clear floor, which is comfortable for a walkway plus a slim piece of storage furniture.<\/p>\n
Drop the room width to 1.9m and the same bed leaves under 90cm, which still works as a walkway but rules out furniture along that side. At that point storage has to go at the foot of the bed, under the mattress or on the wall.<\/p>\n
Marking the footprint on the floor with tape remains the most reliable test. Walk the route, open the door, and open imaginary wardrobe doors before you buy. Our modern beds UK sale<\/a> listings include full external dimensions to make that exercise accurate.<\/p>\n A 90cm mattress takes a single fitted sheet at 90cm by 190cm and a single duvet at 135cm by 200cm. Mattress protectors follow the same sizing, though the skirt depth varies, so check it against your mattress depth if you have chosen something deeper than 25cm.<\/p>\n Rolled mattresses have made single mattresses far easier to get upstairs. They arrive compressed, unroll onto the base and reach full loft within a day or two. For a loft conversion or a house with a tight turn on the stairs, that is often the deciding factor.<\/p>\n Slat spacing affects mattress support and, on some mattresses, the warranty. Gaps of around 7cm or less suit most foam and pocket sprung mattresses. Wider gaps can allow the mattress to sag between slats over time.<\/p>\n Two 90cm beds side by side occupy 180cm plus whatever gap you leave between them. Placed with a shared bedside table in the middle, they need around 220cm of wall, which is close to the space a king size bed would take.<\/p>\n The advantage is flexibility. A guest room set up this way handles two separate visitors, a couple travelling with a child, or siblings sharing a room. It also lets each sleeper choose their own mattress firmness, which is difficult on a shared double.<\/p>\n If floor area is the constraint rather than wall length, bunk beds stack the same two sleeping surfaces into one footprint. Check ceiling height carefully: the top bunk needs enough clearance for an occupant to sit up comfortably. Our modern bunk beds UK<\/a> range lists total heights so you can compare against your ceiling.<\/p>\n Under bed drawers add storage without touching the floor area. On a single, a two drawer base along one side is common, and it holds bedding, towels or clothing that does not need hanging.<\/p>\nBedding and Mattress Compatibility<\/h3>\n
