A 3/4 bed, often called a small double or three quarter sits between a single and a standard double in both size and purpose. It’s wide enough for added comfort but compact enough to suit smaller rooms, making it ideal for guest spaces, teens or solo sleepers in tight interiors. With just the right balance between space and efficiency, it helps maximize room layout without sacrificing rest. Knowing its exact dimensions can make furniture planning more precise and practical.
What size is a 3/4 bed?
A standard bed that falls between a single and a full double is regularly referred to as a 3/4 bed in the UK, offering a smart balance between space-saving design and sleeping comfort. What size is a 3/4 bed? Typically, it measures 120 cm in width and 190 cm in length—or approximately 4 feet by 6 feet 3 inches in imperial units. With around 30 cm more width than a single bed, it offers noticeably more room to stretch out without occupying as much space as a full-size double.
This makes it a popular choice for compact bedrooms, guest rooms, or multipurpose spaces. The added width can make a real difference for solo sleepers, growing teens, or anyone needing a bit more room at night while still keeping floor space open.
Three-quarter bed vs small double: is there a difference?
The terms “three quarter bed” and “small double bed” are frequently used interchangeably in the UK, and for good reason: in most cases, they refer to the same size 120 x 190 cm. However, branding differences or regional preferences can sometimes cause confusion.
In some retail settings, “small double” is used more often in product listings, especially for mattresses and bedding. “Three quarter bed” may appear more in older furniture references or in informal conversation. But in practical terms, they represent the same sleeping surface and require the same size of mattress and bedding.
Standard 3/4 bed dimensions explained
While the sleeping surface of a 3/4 bed is standardized, the overall dimensions can vary slightly depending on the bed frame. Upholstered or wooden frames, storage bases and integrated headboards can all add to the final footprint.
For example:
- A minimal metal frame may only add 2–3 cm around the mattress
- A padded headboard and base may increase the total width to 130 cm or more
- Storage drawers or lift-up ottoman bases may require extra room at the sides or foot of the bed
It’s worth measuring not just the bed itself, but also the space needed to move around it comfortably. Leave at least 60–70 cm of clearance on each side where possible, especially in rooms where the bed is used daily.
How much space does a 3/4 bed need in a room?
While the mattress itself measures 120 x 190 cm, the space required for a 3/4 bed depends on the overall frame design and intended use of the room. In compact bedrooms, this size is often chosen specifically to leave more open floor area. But it still requires thoughtful planning - especially if you’re placing other furniture nearby.
As a rule of thumb:
- A minimum room size of 2 x 2.5 meters allows for basic clearance around the bed
- For shared or guest rooms, aim for at least 2.5 x 3 meters to allow for storage and movement
- If using a 3/4 bed with drawers or an ottoman lift, make sure there’s enough space to fully open them
In narrow or awkwardly shaped rooms, consider a frame with built-in storage or one without footboards to maintain visual openness.
Who is a 3/4 bed ideal for?
The 3/4 size is frequently underestimated, but it fits a surprising range of users.
It’s commonly chosen by:
- Teenagers or young adults transitioning from a single bed
- Solo sleepers who want more space without committing to a full double
- Guest rooms that double as offices or reading nooks
- Couples in small flats who occasionally sleep apart or prefer individual beds
For regular two-person use, a 3/4 bed may feel tight, particularly for taller or restless sleepers. But for occasional use, or in homes where every square inch matters, it’s a smart compromise.
What mattress and bedding fit a 3/4 bed?
A 3/4 size bed requires a 120 x 190 cm mattress, sometimes listed as a small double mattress. Fortunately, many major UK mattress brands carry this size, including in memory foam, pocket sprung, hybrid and orthopaedic options. Always check measurements before buying, especially for upholstered or custom-made frames.
For bedding, standard small double sheets and duvets will fit. Flat sheets labelled for double beds can also be used, though they may need a bit more tucking. When selecting duvets or blankets, consider a full-size double (200 x 200 cm) for more coverage, especially if the sleeper tends to move around.
Is a 3/4 bed right for you? Final thoughts
Choosing a bed size is about more than just fitting furniture, it's also about daily use and comfort. A 3/4 bed, also known as a small double or three-quarter, offers a compact yet comfortable option for one person. It’s well-suited to growing teens, solo adults or anyone furnishing a smaller room without wanting to compromise on sleep space. Its dimensions strike a useful balance between saving room and supporting rest.
