The difference between a small double and a standard double bed comes down to just ten centimetres in width, which does not sound like much until you are standing in a room trying to work out whether it will actually fit. That ten centimetres genuinely changes how a bedroom feels to move around in, so it is worth understanding before you order rather than after the frame arrives.
The actual measurements
A small double, sometimes called a four foot bed, measures 120cm wide. A standard double measures 135cm wide. Both are typically 190cm in length, so the difference is entirely in the width rather than how much legroom you get. For a single sleeper, that extra width on a standard double is a genuine comfort upgrade. For two people sharing, the small double starts to feel noticeably tighter, particularly for taller or larger builds.
When a small double is the right call
Small doubles suit box rooms, guest rooms and any bedroom where a standard double would leave awkward gaps around the wardrobe or door. They are also a common choice for a single adult who wants more room to spread out than a single bed offers, without needing the full footprint of a double. Our small double bed collection covers this size across most of our frame styles, including upholstered and storage options.
If you are choosing a small double specifically for the storage benefit, it is worth looking at our small double mattress range alongside the frame, since not every mattress type is stocked in every size and it is easier to confirm availability before committing to a frame.
When it is worth the extra width
If two adults will be sharing the bed regularly, the standard double is usually worth the extra space even in a smaller room, since the alternative is two people compromising on comfort every night to save a relatively small amount of floor space. Our double bed collection has the widest range of styles overall, simply because it is the most commonly chosen size across the whole range.
It is also worth remembering that if the room genuinely cannot take a standard double, the next step up in comfort is not always a bigger bed. Sometimes it is a better mattress on the small double you already have space for, particularly a hybrid mattress that makes better use of the width available.
Measuring before you decide
The most reliable way to decide is to mark both sizes out on the bedroom floor with tape before ordering anything. Include space for the door to open fully and any wardrobe doors to clear, since these are the measurements people forget most often. If you are still unsure after measuring, our full bed frame collection lets you filter by size directly, which makes comparing the two widths across the same frame style much easier.
