A three quarter bed is 120cm wide, which is just under 4ft, and 190cm long. In UK retail it is almost always sold as a small double, so if you are searching for one, that is the term that will bring up results. The name comes from its position between a 90cm single and a 135cm double: roughly three quarters of the way to a double, hence the shorthand.
To put the width in context, it gives a single sleeper 30cm more room than a standard single, and it gives two sleepers 60cm each, which is narrower than a single bed per person. That is the honest trade off at the heart of this size.
The terminology causes real confusion. In the UK, three quarter and small double describe the same 120cm by 190cm bed. Some older British beds and antique frames described as three quarter are closer to 107cm or 122cm, because sizing was less standardised before the modern retail conventions settled.
To complicate matters, 120cm by 190cm is sometimes labelled a queen in the UK, particularly by importers, whereas in America a queen is a much larger 152cm by 203cm bed. If you are buying from an overseas listing, always check the centimetre measurements rather than trusting the size name.
The practical consequence is bedding. A small double fitted sheet must be cut for 120cm by 190cm. Neither single nor double sheets fit properly, which is the most common frustration people report with this size and the reason it is worth buying bedding at the same time as the bed.
The small double solves a specific and very British problem: a bedroom too narrow for a double but wasted on a single. Second bedrooms in terraced houses, box rooms in newer developments and loft conversions all tend to sit in that range.
It works particularly well for a teenager who has outgrown a single, for a single adult who likes room to spread out, and for a guest room that occasionally needs to sleep two. It is also a sensible choice for a room where the bed has to share space with a desk or a wardrobe, since the 15cm saved against a double is often exactly what a chest of drawers needs.
Where it works less well is as a permanent bed for two adults. At 60cm each, most couples find it tight for regular use. If two people sleep in the room every night and the floor plan allows it, a double or king will serve better. Our modern small double beds UK sale range covers the 120cm size, with double and king frames alongside for comparison.
A 120cm frame typically finishes at 128cm to 140cm wide once the surround is counted, and around 195cm to 205cm long with a headboard. Allow 60cm of clear floor on any side you walk along and the bed needs a room around 2.4m to 2.6m wide for access on both sides.
In practice, many rooms taking a small double will have the bed against one wall, which is perfectly workable. It makes bedding changes slightly harder, and the inside sleeper has to climb out, but it frees a genuine walkway and space for furniture.
Tape the footprint out before ordering. Mark the door swing too, since a 190cm bed in a 2.4m room leaves little margin for a door that opens inwards. And check the loft hatch, stair turn and landing width if the bed is going upstairs, because 190cm components still need to travel that route.
Mattress choice follows the same logic as any other size. Pocket sprung suits sleepers who want responsive support with less motion transfer. Foam contours closely and suits side sleepers. Hybrids sit between the two. Depth is worth watching, since a deep mattress on a 120cm frame can make the bed look narrow and top heavy.
For bedding, buy small double or 4ft fitted sheets specifically. Duvets are more flexible: a double duvet at around 200cm by 200cm works well on a 120cm mattress and gives generous overhang, while a single duvet will look mean. Two standard pillows at 74cm wide come to 148cm, which is wider than the mattress, so many people use one large pillow plus a smaller cushion, or angle two pillows slightly.
If storage is tight in the room, an ottoman base in this size gives back a useful volume beneath the mattress. Pair it with slim storage rather than bulky pieces, and our modern chest of drawers UK sale range includes narrower designs suited to rooms where the bed already takes most of the width.
A 120cm bed can look slightly lost against a wide wall, so the styling job is to give it presence without adding bulk. A taller headboard draws the eye upward and makes the bed read as more substantial. Wall lights either side, rather than table lamps, keep surfaces clear and add symmetry.
Keep bedding simple. Two pillows, a folded throw and one or two cushions is enough on a bed of this width, and more than that starts to swallow the sleeping surface. A throw around 130cm to 150cm wide covers a small double neatly without excess fabric pooling on the floor.
Storage above the bed, in the form of a shelf or a pair of small floating units, uses the vertical space that a narrow room usually has going spare. Similarly, a full length mirror opposite the window adds depth without taking floor, and there are options across our bedroom mirrors UK sale range that suit compact bedrooms.
Because 120cm is a less common size than single or double, check availability of both the frame and the mattress before committing. It is worth confirming the mattress size is stocked in the firmness you want, since the range in a small double is narrower than in a double.
Frame construction matters more on narrower beds than people expect. A 120cm frame with widely spaced slats and no central support leg can flex, which is a common source of noise. Look for a central rail or closely spaced sprung slats, and check the internal rail measurement matches 120cm exactly. You can compare construction across our modern beds UK sale range, and browse the wider bedroom collection at Furniture in Fashion UK if you are furnishing the whole room.
A small double usually sits between a single and a full double on price, and the gap is rarely large enough to be the deciding factor on the frame. Where it does matter is bedding, because 120cm bedding is stocked less widely than single or double, so the choice is narrower and prices are sometimes higher for the same quality.
Factor that in before you decide. If you expect to buy several duvet sets and fitted sheets over the life of the bed, a standard double may work out cheaper to live with, provided the room genuinely takes the extra 15cm of width.
This size suits guest rooms particularly well. It gives a single visitor a genuinely generous bed, and it takes two people at a push for a night or two, which is more than a single can offer. Because it is narrower than a double, you keep enough floor space for a chair, a luggage rack or a small desk, which makes the room usable between visits.
If the room doubles as a study or a home office, the 15cm you save over a double is often exactly what allows a desk to sit against the opposite wall without the room feeling blocked.
At 120cm wide, a centre support rail matters less than it does on a double or king, but it is still worth having on a wooden frame with solid slats. Without one, slats can bow gradually under a heavier mattress, and bowing is the usual cause of a sagging feel through the middle of the bed.
Check the slat spacing too. Gaps wider than about 7cm allow a foam or pocket sprung mattress to dip between them over time, which shortens its life and can invalidate a mattress warranty. Closely spaced slats or a solid platform base are the safer choice for this size.
Yes. In UK retail both terms describe a 120cm by 190cm bed, sometimes also listed as a 4ft bed.
Occasionally, yes. Each person has around 60cm, which is narrower than a single bed, so most couples find it too tight for every night.
Small double or 4ft fitted sheets. A standard double duvet works well over the top, but single and double fitted sheets will not fit the mattress correctly.
A double is 135cm by 190cm, so it is 15cm wider. Both are the same length, meaning the choice is purely about width and floor space.
Often not. Older frames vary, so measure the internal rails before ordering a mattress, since a modern 120cm mattress may not fit an antique frame.
