What Is the Size of a Single Bed?

A single bed in the UK measures 90cm wide by 190cm long, which is 3ft by 6ft 3in. Below it sits the small single at 75cm by 190cm, sometimes described as a cabin or narrow single. Both use the same 190cm length, so the difference is width alone.

The single is the most adaptable size in the range. It works for a child, an adult in a small room, a guest room, and a shared room where two beds are needed. This guide covers the measurements, the rooms it suits, and how to make the most of the space around it.

Single and Small Single Measurements

A standard UK single mattress and base measure 90cm by 190cm. A small single measures 75cm by 190cm. Single duvets are commonly 135cm by 200cm, and they work on both widths, with a longer drop on the small single.

Fitted sheets need to match the exact width. A 90cm sheet on a 75cm mattress will not hold its shape, and there is no workaround. If you have a small single, buy sheets specified for 75cm rather than assuming single bedding covers both.

Room Size for a Single Bed

Placed against a wall with a walkway on one side, a single needs a room of about 170cm by 250cm. In the middle of a room with access on both sides, allow around 220cm across. A small single reduces the first figure by 15cm, which is often what makes a box room workable.

The 190cm length is the fixed constraint. In a very short room, that dimension decides where the bed can go, and it usually means placing it along the longest wall or into an alcove. Check for radiators and skirting details at the head end, since either can hold the bed a few centimetres off the wall.

Single Beds for Children

A single at 90cm by 190cm suits a child from around the age of four or five and continues to work into adulthood, which is why it is rarely worth buying a shorter junior bed unless the room genuinely cannot take a full single. The 190cm length accommodates most teenagers comfortably.

Frame height matters more for children than for adults. Lower frames are easier to get into and out of, and less concerning if a young child rolls out. Solid frames with rounded edges and no protruding corners suit rooms where children play on the floor beside the bed. Our modern childrens beds UK sale range includes low profile designs suited to younger children.

Two Singles in One Room

Two singles side by side with a shared walkway need around 250cm of width: 90cm plus 90cm plus a 60cm gap between them, plus frame allowances. In a narrower room, two small singles bring that down to around 220cm.

Where the room cannot take both side by side, the alternatives are bunk beds, which use vertical space, or a single with a trundle, which stores the second bed underneath. Bunk beds keep the floor permanently clear and suit rooms with good ceiling height. Our bunk beds UK sale range covers the standard 90cm width on both levels.

Storage Around a Single Bed

A single leaves more usable wall than any other size except a small single, which is the main reason it works in tight rooms. That said, storage still needs planning. A single with drawers underneath removes the need for a chest, leaving the wall free for a wardrobe.

Where the room is very small, look at height rather than width. A tall narrow wardrobe holds more per square metre than a low wide one, and a slim chest with four or five shallow drawers uses less floor than a two drawer wide unit of the same capacity. Our 1 door wardrobes UK sale suit box rooms where a single has taken most of the floor.

Single Beds in Guest Rooms

In a guest room that doubles as an office or hobby space, a single frees floor area that a double would consume. A daybed with a single mattress reads as seating during the day, and a trundle underneath handles two guests when needed.

The mattress matters more in a guest room than people expect, because a guest bed used a dozen nights a year still needs to be comfortable on each of them. A mid depth pocket sprung single mattress serves better than a thin foam one, and it will not show wear from light use. Our mattresses UK sale range includes single sizes suited to occasional use.

Frame Styles at Single Size

Because a single occupies little floor, frame style is more about the look of the room than about space saving. Metal frames read as the lightest visually and suit rented rooms and older children. Wooden frames are hard wearing and pair easily with existing furniture. Upholstered singles give a softer finish and are comfortable to lean against, which suits a room used for reading or study.

Height is worth considering. A higher frame creates useful under bed space for boxes, while a low frame keeps a small room feeling more open. Daybed styles with a back and sides work in a room that also functions as a sitting space. Our single fabric beds UK sale collection covers both low and higher profiles.

Getting the Details Right

Measure the clear wall run, allow for the frame’s external width rather than the mattress, and mark the footprint on the floor before ordering. In a small room, 5cm either way genuinely decides whether a door opens fully or a drawer pulls out.

Choose bedside furniture in proportion. Alongside a single, a cabinet of 30cm to 35cm wide sits better than a full sized one, and a wall mounted shelf takes no floor at all.

Frequently Asked Questions

What size is a single bed in the UK?
90cm wide by 190cm long, or 3ft by 6ft 3in. A small single is 75cm by 190cm, using the same length but 15cm narrower.

Is a single bed long enough for an adult?
At 190cm it suits most adults up to around 5ft 10in. Taller sleepers may find their feet reach the end, in which case a king size length of 200cm is the alternative, or a single frame without a footboard.

Will single bedding fit a small single bed?
A single duvet works with a longer drop at the sides, but fitted sheets will not. Buy sheets specified for a 75cm mattress width.

What room size does a single bed need?
About 170cm by 250cm with the bed against a wall and a walkway on one side. Access on both sides needs around 220cm of width.

At what age can a child move to a single bed?
Most children move to a full single at around four or five. Since a 190cm single works into adulthood, it usually makes sense to go straight to that size rather than buying a shorter junior bed first.
