A standard single bed in the UK is 90cm wide, which works out at roughly 3ft. The mattress measures 90cm by 190cm, and the bed frame itself usually sits between 95cm and 100cm wide once the side rails and any headboard uprights are accounted for. If you are measuring a room and planning around a single bed, allow around one metre of width rather than exactly 90cm.<\/p>\n
That 90cm figure is consistent across almost every British bedding and mattress manufacturer, which is why single fitted sheets, duvets and mattress protectors sold here fit interchangeably. It is worth knowing that the width refers to the mattress, not the frame, because this is where most measuring errors happen.<\/p>\n
British bed sizing settled into imperial measurements long before metric labelling arrived, and the single bed was based on a 3ft width. When the industry moved to centimetres, 3ft translated to 91.44cm, which was rounded to a clean 90cm. The length followed the same pattern: 6ft 3in became 190cm.<\/p>\n
This matters when you are shopping because you may still see both sets of figures used side by side. A bed listed as 3ft, a bed listed as 90cm and a bed listed as a standard single are all describing the same thing. Occasionally you will find frames labelled as small singles at 75cm wide, which are made for very tight rooms and children’s bedrooms, and these need their own bedding.<\/p>\n
The gap between mattress width and overall frame width is the detail that catches people out. A slim metal single frame may add only 4cm or 5cm in total. A padded fabric frame with deep side panels can add 10cm or more, and a wooden frame with chunky posts can add a similar amount.<\/p>\n
If you are fitting a bed into an alcove, between a wall and a wardrobe, or into a box room where every centimetre counts, ask for the external frame dimensions rather than the bed size. Our product listings give the full external measurements, so you can compare a slimline design against a more substantial one before committing. Browsing our range of single fabric beds UK sale<\/a> gives a clear sense of how much the upholstery adds to the footprint.<\/p>\n Width alone does not tell you whether a single bed suits a room. You also need circulation space. As a working guide, allow at least 60cm along one long side of the bed for comfortable access, and 70cm to 75cm if that route is the main path in and out of the room. A door that opens inwards needs its full swing clear of the bed frame.<\/p>\n In a typical UK box room measuring around 2.1m by 2.6m, a single bed placed against the long wall leaves a usable walkway and enough depth at the foot of the bed for a slim chest of drawers. Push the bed into a corner and you gain floor area but lose easy access to one side, which makes changing the bedding harder. That trade off is usually acceptable in a child’s room and less so in a room used by an adult every day.<\/p>\n Single beds earn their place in guest rooms, children’s rooms, loft conversions and any room where the layout leaves an awkward run of wall. Two singles positioned with a shared bedside table between them create a flexible guest room that suits both a couple travelling with a child and two separate visitors.<\/p>\n Loft rooms with sloping ceilings often only work with a single, because the low eaves side needs to sit at the head or foot rather than along the sleeping edge. Measure the ceiling height at the point where you will sit up in bed rather than at the highest point of the room.<\/p>\n For a room that doubles as a study or a hobby space, a single frame with built in storage frees up the floor. Our modern single wooden beds UK<\/a> include designs with drawer bases that hold spare bedding without adding a separate cabinet.<\/p>\n Single duvets in the UK measure 135cm by 200cm, which gives an even overhang on both sides of a 90cm mattress. Fitted single sheets are cut to 90cm by 190cm with a skirt depth that varies by brand, so check the depth if you have a mattress deeper than about 25cm.<\/p>\n A common mistake is buying a double duvet for a single bed on the assumption that more is better. The extra fabric pools on the floor, drags off during the night and makes the bed look untidy when made. Stick to single sizing and add a throw across the foot of the bed if you want more visual weight.<\/p>\n Width is only one part of the comfort equation. Mattress depth affects how high the bed sits, and total sitting height matters more in a small room than most people expect. A low platform frame with a 20cm mattress may put the top of the mattress at around 45cm from the floor, which suits younger children and low ceilinged rooms.<\/p>\n A divan style base with a deeper mattress can push that height past 60cm, which feels more substantial but reduces headroom under a sloping ceiling and can make a small room feel busier. If the bed sits under a window, check that the mattress top does not block the sill or the opening.<\/p>\n In a 90cm wide bed, the area under the mattress is one of the most useful storage spaces in a small bedroom. Drawer bases give quick access to bedding and out of season clothing. Lift up bases give a deeper single compartment, which suits bulkier items such as spare duvets and suitcases.<\/p>\n If under bed storage is not an option because of a low frame, look upwards instead. A tall narrow chest of drawers takes far less floor space than a wide low one and stores the same volume. Our modern chest of drawers UK sale<\/a> selection includes slim designs made for narrow wall runs beside a single bed.<\/p>\n Once a room measures around 2.4m across, a small double at 120cm wide becomes worth considering. That extra 30cm makes a noticeable difference to an adult sleeper, though it eats into the walkway and the space for bedside furniture.<\/p>\n The decision usually comes down to who sleeps in the room and how often. A guest room used a handful of times a year benefits from the extra floor space a single provides. A room used nightly by a teenager or an adult usually benefits from the extra mattress width instead. Measuring both options on the floor with masking tape before buying gives a far clearer answer than working from a drawing.<\/p>\n A 90cm bed can look lost against a long wall. Two square pillows behind a standard pillow fill the headboard width and give the bed presence. A headboard that extends slightly wider than the mattress has the same effect.<\/p>\nHow Much Floor Space a Single Bed Really Needs<\/h3>\n
