What Is the Width of a 3/4 Bed?

The Width You Are Asking About

A 3/4 bed is 120cm wide, which is 4ft. It is more commonly sold in the UK as a small double, and it measures 120cm by 190cm, sharing the same length as a standard single and a standard double.

The name comes from its position between a single and a double. At 120cm it is wider than a 90cm single but narrower than a 135cm double, sitting roughly three quarters of the way toward the wider size in older imperial reckoning.

Where a 3/4 Bed Fits Among UK Sizes

Set against the other UK sizes, the small double slots neatly into a gap that a lot of British bedrooms need filled. A single is 90cm by 190cm. A small double or 3/4 bed is 120cm by 190cm. A double is 135cm by 190cm. A king is 150cm by 200cm.

The 15cm difference between a small double and a standard double sounds trivial on paper. In a narrow box room it can be the difference between a bedside cabinet fitting and not fitting, or between a walkway you can use and one you have to shuffle down sideways.

Why This Size Exists in UK Homes

Many British houses were built long before modern bed sizes settled into their current form. Victorian and Edwardian terraces, post war semis and 1960s estates all commonly include a second bedroom that is genuinely awkward: too big to be a study, too narrow for a comfortable double.

The small double was the practical answer. It gives a guest or a teenager considerably more room than a single without demanding the floor space a double needs. It is also a sensible size for a single adult who simply likes room to spread out.

The trade off appears when two adults share it every night. At 120cm, each person has 60cm, which is narrower than a single bed’s width each. For occasional guests that is fine. For nightly sharing, most couples eventually want the extra 15cm of a double or more.

Frame Width and Real Floor Space

As with every bed size, the 120cm figure is the mattress. The frame adds to it. Metal small double frames often add 8cm to 10cm overall. Wooden frames add roughly 10cm to 16cm. Upholstered fabric frames add the most, commonly 16cm to 20cm.

So a small double frame will usually occupy between 128cm and 140cm of width. Compare that against your available wall run, then subtract 1cm to 2cm for skirting boards, which stop the frame sitting flush against the wall.

For access, allow 60cm of clear walkway on any side you use. A small double against one wall with single sided access can work in a room around 195cm wide. With access on both sides you want about 255cm. Those figures are what make the size so useful in tight rooms.

Our modern small double fabric beds UK sale range lists frame widths alongside mattress size, which makes checking against a tight alcove straightforward.

Choosing a Frame at This Size

Because small doubles usually go into smaller rooms, frame choice affects the room more than it would in a large bedroom.

Avoid footboards where you can. A footboard adds length and creates a visual stop at the end of a narrow room, which makes the space read as shorter than it is. An open frame with no footboard keeps the floor line continuous.

Consider headboard height carefully. A tall solid headboard in a small room takes up a lot of visual weight. Slim panelled or open slatted headboards are lighter and let the wall behind stay visible.

Storage frames earn their keep at this size. An ottoman small double opens to reveal the whole 120cm by 190cm footprint, which in a box room may be more storage than any wardrobe you could fit alongside. Check ceiling clearance so the lid opens fully.

Metal frames are worth a look in rented properties and box rooms because they are slim, light and easy to move. Our modern small double metal beds UK range covers the size in a range of finishes.

Mattresses and Bedding for a 3/4 Bed

Mattresses are made in small double, though the range is smaller than for singles and doubles. Pocket sprung construction is worth prioritising if two people will share, because the independent spring response reduces the roll together effect that becomes more noticeable on a narrower mattress.

Edge support matters here more than at any other size. With sleepers only 60cm apart from the centre line, both are close to the mattress edges. A mattress that softens at the perimeter effectively reduces the usable width, so reinforced edges keep the full 120cm sleepable.

Bedding is the practical catch. Small double duvets and fitted sheets exist, but the choice is much narrower than for standard doubles, and some designs are only made in the mainstream sizes. Confirm you can get the bedding you want before ordering the bed. Some people use double bedding on a small double, accepting a longer drop at the sides, which works for duvets though not for fitted sheets.

Furnishing a Small Double Bedroom

The point of a small double is the space it leaves over, so use that space deliberately. Narrow bedside cabinets around 30cm to 40cm wide fit where wider ones will not, and taller designs give drawer volume without extra footprint. Our modern wooden bedside cabinets UK sale range includes slim options suited to tight gaps.

Where a bedside table will not fit at all, a wall mounted shelf and a wall light do the same job with no floor cost. That single substitution often makes a box room feel considerably less crowded.

For clothing, measure the remaining wall run first. Sliding doors remove the clearance a hinged wardrobe door needs, which is frequently the deciding factor in a narrow room. Our modern 2 doors wardrobe UK sale options include compact widths that suit second bedrooms.

A mirror on the wall facing the window makes a genuine difference to how light a narrow room feels, and it costs no floor space at all. Browse our modern wall mirrors UK selection for options in a range of proportions.
