What Size Is a Single Bed?

A single bed in the UK is 90cm wide by 190cm long, which is 3ft by 6ft 3in. That is the standard single mattress size, and once a frame is added the overall footprint typically reaches 95cm to 100cm wide and 195cm to 205cm long depending on the headboard depth.

There is also a small single, sometimes called a cot bed size or 2ft 6in bed, at 75cm by 190cm. At the other end, a long single at 90cm by 200cm suits taller sleepers, though it is less commonly stocked. If a listing simply says single without qualification in Britain, assume 90cm by 190cm.

Single Bed Sizes in Context

Placed alongside the other UK sizes, the single is the narrowest standard option. Small single: 75cm by 190cm. Single: 90cm by 190cm. Small double: 120cm by 190cm. Double: 135cm by 190cm. King: 150cm by 200cm.

The 190cm length runs through all of these except king and super king, which is genuinely useful. It means a single mattress and a double mattress are the same length, so a room deep enough for one is deep enough for the other. Only the width changes, which simplifies planning considerably.

It is worth noting that a single at 90cm gives one sleeper more width than each person gets on a double bed, where two people share 135cm and take 67.5cm each. Single beds are often thought of as small, but for one person they are more generous than a shared double.

Where Single Beds Work Best

Children’s bedrooms are the most common use, and the size suits them for years. A single gives room to grow while leaving floor space for play, a desk and storage, which matters far more in a child’s room than mattress width.

Box rooms and third bedrooms are the second natural fit. Many UK third bedrooms are under 2.5m in one direction, and a single bed is often the only option that leaves the room genuinely usable. Positioned along one wall, it leaves a clear floor area and room for a wardrobe.

Guest rooms benefit from two singles rather than one double, because the arrangement flexes. Two singles side by side with a gap suit friends or siblings, and some frames can be pushed together to form a wider sleeping surface for a couple. In a room that also serves as a study, a single leaves space for a desk under the window.

Bunk beds and mid sleepers use single mattresses, so the same 90cm by 190cm bedding applies. If you are buying for a bunk, check the maximum mattress depth the frame allows, since a deep mattress on a top bunk reduces the effective height of the safety rail. Our modern bunk beds UK sale range lists depth limits alongside dimensions.

Room Size and Layout for a Single

A single bed needs surprisingly little. A room of 2m by 2.5m can take a single with walking space on one side, and 2.4m by 2.7m gives comfortable clearance on both sides plus room at the foot. Because the footprint is compact, the layout choices matter more than the measurements.

Placing the long side against a wall is the standard approach in a small room, and it works better with a single than a double because a 90cm reach across the bed to change bedding is easy. This frees the rest of the floor for a desk, a chest of drawers or open play space.

Placing the head of the bed against the wall with both long sides free suits rooms where the bed will be used as seating during the day, and it makes bedding changes simplest of all. In a shared children’s room, two singles along opposite walls with a shared chest between them is the most efficient arrangement.

Under a window, keep the headboard low so light and the window catch stay accessible. In a loft room, put the bed where the ceiling is lowest, since you only need sitting height. Our modern single wooden beds UK sale range includes low profile designs suited to both situations.

Choosing a Single Bed Frame

Metal frames are the lightest visually, with slim uprights that barely interrupt a sightline. In a small room, that matters more than it sounds, since a bulky frame can dominate a 2m wall.

Wooden frames bring warmth and are the most common choice for children’s rooms, with painted finishes that suit a changing scheme and natural grain that works in a guest room. Fabric frames add softness and a padded headboard for reading, which appeals in a teenager’s room. Our modern single fabric beds UK selection covers headboard heights from low to generous.

Storage is where single beds punch above their weight. Ottoman lift up singles and divan bases with drawers turn the area under a compact bed into useful capacity, which is often the only storage a box room can offer. Guest beds with a pull out second mattress underneath double the sleeping capacity of a small room without doubling the footprint.

Check slat spacing of around 7cm or less if you are using a foam or hybrid mattress, and confirm there is a central support rail on any frame with a slatted base. Even at 90cm, slats without central support will flex over time.

Mattresses and Bedding for Singles

Single mattresses come in the same constructions as larger sizes: open coil, pocket sprung, memory foam and hybrid. For a child, a firmer, medium support mattress with a washable cover is practical. For a guest room used occasionally, a mid depth pocket sprung mattress offers comfort without needing frequent rotation.

Rolled mattresses are especially convenient in this size, arriving compressed and expanding in the room, which solves access problems in narrow staircases and loft hatches. Check the recommended expansion time before making up the bed.

Bedding is widely available. Single fitted sheets measure 90cm by 190cm, with depth stated separately. Single duvets are usually 135cm by 200cm, giving sensible overhang on both sides. One standard pillow at 50cm by 75cm suits the width, and a single square cushion in front is enough styling for a bed this size.

Furnishing Around a Single Bed

The advantage of a single is what it leaves behind, so plan that space deliberately. A narrow bedside table keeps the walkway clear, and wall mounted lighting frees the surface entirely. In a child’s room, a low bookcase doubles as a bedside surface and keeps books within reach.

For clothing, a two door wardrobe or a tall narrow chest suits the smaller floor area better than a wide low unit. Our modern wooden chest of drawers UK sale range includes narrow designs that fit alongside a single bed without crowding it.

A mirror positioned to catch daylight makes a small single bedroom feel considerably larger, and a rug beside the bed defines the sleeping area in a room that has to do several jobs.

Making a Single Bed Work Over Time

A single bed often has to serve a room for years while the person using it changes considerably, so it pays to think past the immediate need. For a child moving out of a cot bed, a low frame with a rounded profile is easier to climb into and less punishing if they roll out. The same 90cm mattress will still fit when they are a teenager, so the frame is usually what dates first rather than the size.

Rooms change too. A single bed placed lengthways against a wall frees the centre of the floor, which suits younger children who play on the ground. Later, pulling the bed away from the wall and adding a bedside surface on both sides makes the room feel more grown up without any change in footprint. A day bed or one with a trundle underneath adds a second sleeping place for visitors, which is useful in a house with only two bedrooms.

Consider the mattress separately from the frame. Children are lighter, so a firmer surface that feels supportive to an adult can feel hard to a small child, while a soft mattress compresses too much as they grow. A medium tension mattress covers the widest range of weights and tends to remain suitable as they get taller. Whichever you choose, check that the slats or platform give even support across the full 190cm, since gaps that are too wide shorten the life of any mattress.
