Fabric Double Beds or Fabric Single Beds? How to Decide

The quickest way to decide between a fabric double bed and a fabric single bed is to ask three questions: who will sleep in it, how wide the room is, and how long the bed needs to last. Choose a single for young children, narrow box rooms and twin guest rooms. Choose a double for adults, couples, teenagers who have outgrown a single, and spare rooms that need to welcome visiting couples. If the room sits somewhere in between, a small double is often the sensible compromise.

For most adults with a standard UK bedroom, a double will be the more comfortable long term choice. Our modern double fabric beds UK are a useful reference point while you weigh up the options below.

The Sizes Side by Side

A UK single mattress measures 90 x 190 cm. A standard double measures 135 x 190 cm. The difference is 45 cm of width, while the length is the same. A small double, at 120 x 190 cm, sits between them.

Those are mattress sizes. Fabric beds add padded side rails and a headboard, so the overall frame is larger. Depending on the design, a fabric single might occupy roughly a metre of width, while a double can take up considerably more once wide rails or a winged headboard are included. Always check the external dimensions of the specific bed rather than assuming.

When you plan the room as a whole, it helps to look at the bed alongside wardrobes, drawers and bedside tables. Browsing our modern bedroom furniture UK collection with your room measurements to hand makes it easier to see whether a double leaves enough space for everything else.

Start with Who Sleeps There

For a single adult, both sizes are possible, but most adults find a double noticeably more comfortable. A single gives each sleeper 90 cm of width, which leaves little room to turn over or stretch out. If you sleep alone and the room allows it, a double or small double usually improves sleep quality more than any other bedroom change.

For couples, a double is the practical minimum, and many couples find a king size more comfortable still. Two singles pushed together can work in a guest room, but the gap in the middle makes it an occasional arrangement rather than a nightly one.

For children, a single is generally the right starting point. It leaves floor space for play and storage, and it is scaled to their size. Teenagers are a different matter, which we look at below.

Measure the Width of the Room

Width is usually the deciding factor in UK bedrooms. A common guide is to leave around 60 cm of clear floor on each side of a bed you get in and out of from both sides. In a narrow box room, that rule often makes a double impossible unless one side goes against a wall.

Putting a double against a wall is entirely workable for one person, but it is awkward for two, as one sleeper has to climb over the other. If the room is narrow and the bed is for a couple, it may be better to rethink which room becomes the main bedroom.

A single in a narrow room leaves space for a desk, a chest of drawers or a reading chair. That extra floor can make a small room feel like a usable space rather than somewhere you only sleep.

The Small Double as a Middle Path

If a full double feels too large but a single feels mean, the small double is worth a serious look. At 120 cm wide, it gives one adult generous space and works for two people on occasion. It suits smaller main bedrooms in flats, compact guest rooms and older teenagers.

Our small double fabric beds UK bring the same upholstered styles to a slightly narrower footprint. The main thing to remember is bedding: small double sheets and duvets are available but less widely stocked than standard doubles, so it is worth checking you can find covers you like.

Buying for a Growing Child or Teenager

A single is right for most young children, but it may be outgrown sooner than you think. Teenagers often reach adult height in their early teens, and a single starts to feel cramped. If the room is large enough, moving to a small double or a double at this stage gives a bed they can keep into adulthood or take to their first flat.

If you prefer to stay with a single for space reasons, choose a design that will not look childish in a few years. A fabric single with a simple panel or channel headboard grows with its owner far better than a themed bed. Our modern single fabric beds UK include plenty of grown up designs, and our guide to upholstered single beds for UK children and teenagers looks at this age group in more detail.

Guest Rooms: One Double or Two Singles?

Guest rooms raise a different question, because you are planning for visitors you cannot always predict. A double welcomes couples comfortably and suits single guests too. Two singles suit friends, siblings and visiting children who would rather not share a bed.

If the room is wide enough for two singles with a bedside table between them, that layout is very flexible. If it is not, a double is usually the better all round choice. A fabric bed with a softly upholstered headboard also makes a spare room feel warmer and more considered than a basic frame.

Comfort Beyond the Width

Size is not the only factor in how comfortable a bed feels. The mattress matters at least as much, and a good single mattress can be more restful than a poor double. Whichever size you choose, invest in a mattress that suits your sleeping position and weight.

Frame height plays a part too. A bed that is too low can be hard to get out of, especially for older guests, while a very high bed can feel imposing in a small room. Fabric beds come in a range of heights, so it is worth sitting on the edge of a similar bed if you can, or checking the height from floor to top of mattress.

How Each Size Looks in the Room

Floor space is only half of the picture. A bed also has visual weight, and an upholstered frame carries more of it than a slim metal or wooden one. A double with a tall, wide headboard can make a modest bedroom feel dominated by the bed, even when the measurements technically work. In a smaller room, a double with a lower headboard and visible legs often feels far more comfortable than a bulkier design of the same mattress size.

Singles have the opposite challenge. In a larger room, a single can look lost, particularly against a long wall. A headboard with a little more height, a bedside table and a rug beneath the bed help anchor it. Placing a single lengthways against a wall, with cushions along the side, turns it into a daybed during the day, which works well in studies and multipurpose rooms.

If you are furnishing several bedrooms at once, choosing double and single beds from the same family of headboard shapes and fabrics gives the house a consistent look. Children’s rooms and guest rooms then feel connected to the main bedroom rather than furnished separately.

Bedding and Practical Running Costs

Double bedding is the most widely available size in the UK, so you will find the broadest choice of sheets, duvets and covers. Single bedding is also widely available and quicker to wash and dry. Small double sits in between and needs a little more searching.

If you are furnishing several rooms, keeping to the same size across them simplifies bedding storage and means covers can move between rooms as needed.

A Simple Way to Decide

• Choose a single for young children, narrow box rooms and twin guest layouts.
• Choose a small double for one adult in a modest room, or an older teenager.
• Choose a double for couples, adults who want room to stretch out, and spare rooms that host visiting couples.

Mark out the frame dimensions on the floor before you order and walk around them. If you can open the wardrobe, reach the window and move freely, the size will work. You can see the full range of beds and modern bedroom furniture at Furniture in Fashion.

Frequently Asked Questions

How much wider is a double bed than a single?

A UK double mattress is 135 cm wide and a single is 90 cm wide, so a double is 45 cm wider. Both are 190 cm long. The frame adds extra width depending on the design.

Can two adults sleep on a small double?

Occasionally, yes, but most couples find 120 cm tight for nightly use. A standard double or larger is more comfortable for two people sharing every night.

When should a child move from a single to a double?

There is no fixed age. Many families make the change in the teenage years when a single starts to feel short or narrow, provided the room has space for a larger bed.

Is a double bed too big for a box room?

In many box rooms it is, because there is not enough width to walk around it. A single or a small double placed against one wall usually works better in these rooms.
