Is a Small Double Bed a Good Investment? Value Explained

A small double bed is a good investment when the room is between roughly 2.4m and 3m wide, or when the bed will be used mainly by one adult who wants more space than a single provides. At 120cm wide by 190cm long, it gives a solitary sleeper a generous surface while leaving walking space and room for storage that a standard double would swallow. For two adults sharing every night, it is a compromise, and whether that compromise is worth making depends on the room rather than the bed.

The question is really about value rather than size: what you gain in floor space, flexibility and resale appeal against what you give up in sleeping width. Here is how that balance works out in practice.

The dimensions that matter

UK bed sizes are standardised, and the gaps between them are smaller than people assume.

• Single: 90cm by 190cm
• Small double: 120cm by 190cm
• Double: 135cm by 190cm
• King: 150cm by 200cm

A small double is sometimes called a three quarter bed, because it sits roughly three quarters of the way between a single and a king in width. The important numbers are the 30cm it gains over a single and the 15cm it gives up against a standard double.

That 15cm is not trivial for two people. Split between two sleepers it is 7.5cm each, which is about the width of a hand. It is noticeable if you both move in your sleep, and less noticeable if you do not.

The length is identical to a single and a double at 190cm, so a small double is no better or worse for taller sleepers. Anyone over roughly 185cm should be looking at a king size for the extra 10cm of length rather than any of the 190cm sizes.

Where the value actually comes from

The case for a small double rests on what the freed floor space lets you do.

In a room 2.7m wide, a standard double leaves around 67cm on each side if centred. That is technically walkable but tight, and it rules out a bedside table on one side or any furniture along the wall.

Swap to a small double and you gain 15cm, which splits into an extra 7.5cm each side. That is often the difference between fitting a slim bedside cabinet and not fitting one. In a room where the door swings inward or the wardrobe doors open towards the bed, it can be the difference between the room working and the room being awkward.

The gain is greater if the bed sits against one wall, as it often does in a single occupancy room. There the full 15cm goes into one walkway, and the room reads noticeably more open.

Who a small double genuinely suits

Be honest about the primary user, because that determines whether the compromise pays off.

A single adult who wants room to spread out. This is the clearest case. A small double is a considerable upgrade on a single without the footprint of a double, and it is the size most people in this position wish they had chosen.

Teenagers. Gives them space to grow into without redesigning the room, and leaves floor for a desk.

Guest bedrooms. Accommodates a couple occasionally while leaving the room usable for other purposes the rest of the time. For occasional use, the 15cm matters far less than it would nightly.

Box rooms and second bedrooms in terraced houses. Many UK second bedrooms are between 2.4m and 2.7m wide, which is exactly the range where a small double works and a double does not.

Flats and shared houses. Where every square metre is accounted for, and where the bed needs to reach the room up a narrow stair.

Where it is less suitable: couples who share the bed every night and both sleep restlessly, and anyone significantly taller than average who needs the extra length a king provides.

The resale and letting argument

This is often overlooked but matters if you move or let the property.

A second bedroom that can accommodate a double bed is generally described as a double room, which affects how the property is presented. A small double bed lets you demonstrate that a room takes more than a single, without cramming a standard double in so tightly that the room looks unusable in photographs.

For landlords, small doubles are a practical choice in student and professional lets, because they meet tenant expectations of a double room while leaving space for a desk and wardrobe, which are usually required.

What it costs you in bedding

A practical point worth knowing before you buy. Small double bedding, at 120cm by 190cm, is less widely stocked than single, double and king. You will find it, but the choice of designs is narrower and you may not always find a matching set in a pattern you like.

Two workarounds are common. Some people use double duvets on a small double, which gives generous overhang and works well for a single sleeper. Others buy fitted sheets in small double and everything else in double.

Mattress availability is good across all types, from pocket sprung to memory foam, so this is not a limiting factor. Our modern mattresses UK range covers the 120cm size across the main constructions.

Choosing the right small double frame

Since the point of the size is efficiency, the frame should support that.

Consider storage. In a room small enough to warrant a small double, storage is usually short. An ottoman or drawer base recovers the wardrobe space you are unlikely to have. This is where a small double often justifies itself financially: it replaces both a bed and a chest of drawers.

Keep the headboard modest. A tall headboard in a compact room makes the ceiling feel lower. Around 90cm to 100cm total height is a sensible ceiling.

Skip the footboard. It adds up to 10cm to the length and visually cuts the room in half. In a room where you chose a smaller width to save space, giving length back to a footboard makes little sense.

Check external dimensions. Upholstered frames add padding beyond the mattress size. A 120cm mattress can sit in a frame measuring 130cm or more externally, which erodes the space you were trying to save.

Choose a frame that assembles in the room. Especially relevant in flats and terraced houses with tight stairs.

Our small double fabric beds UK sale range covers upholstered options in this size, and there are timber equivalents among the small double wooden beds UK selection.

Furnishing the space you gain

The 15cm you save only counts if you use it deliberately. Plan what goes into that space before the bed arrives.

On the side you gain, a bedside cabinet of around 35cm to 40cm wide will usually fit where nothing fitted before. Choose one with a drawer rather than open shelving, since visible clutter in a small room undoes the sense of space you have just created.

At the foot of the bed, the saved width sometimes allows a narrow chest to sit against the side wall instead of blocking the walkway. Measure the swing of any drawer fronts before committing.

If the room has an alcove, that is usually the best place for hanging storage, since a wardrobe set into a recess does not project into the room. A slim mirror on the opposite wall then carries daylight across the extra floor you have opened up, which reinforces the effect.

Making the decision

Measure before you decide anything else. Mark out both a 135cm and a 120cm footprint on the floor with masking tape and walk the room. Open the door. Open the wardrobe. Stand where you would dress.

If the 135cm layout leaves under 60cm on the access side, or blocks a door or drawer, the small double is the better buy. If both fit comfortably and two adults will sleep there nightly, choose the double.

The value of a small double is not that it is smaller. It is that in the right room it gives you a functional bedroom rather than a room with a bed in it, and that difference is felt every day.

If you are planning the whole room rather than just the bed, viewing frames, storage and bedside pieces together makes the proportions much easier to judge. You can browse the full modern collection at Furniture in Fashion, with free delivery to most UK mainland postcodes.

Frequently asked questions

How wide is a small double bed in the UK?
120cm wide by 190cm long. That is 30cm wider than a single and 15cm narrower than a standard double, with the same length as both.

Can two adults sleep comfortably in a small double?
For occasional use, yes. For nightly sharing it is a compromise, since each sleeper has around 7.5cm less width than in a standard double. Restless sleepers will notice it.

Is small double bedding easy to find?
It is less widely stocked than other sizes, so the choice of designs is narrower. Many people use small double fitted sheets with a double duvet.

What size room suits a small double?
Roughly 2.4m to 3m wide. Below that, a single is more practical. Above it, a standard double will usually fit without compromising the layout.

Does a small double add value to a property?
It helps demonstrate that a second bedroom takes more than a single without the room appearing overcrowded, which is useful when selling or letting.
