Yes, a queen bed is bigger than a double. In UK terms a standard double mattress measures 135cm by 190cm, while a queen measures 150cm by 200cm. That makes a queen 15cm wider and 10cm longer. The complication is that 150cm by 200cm is exactly what British retailers call a king size, so in the UK the words queen and king often describe the same mattress.
This is why the question causes confusion. Queen is an American size name that has drifted into UK conversation through furniture catalogues, streaming television and imported bedding. When someone in Britain asks for a queen bed, they almost always mean what a UK retailer lists as a king.
The UK and the United States developed their bed sizing separately, and the labels never aligned. In the US, a queen is 60in by 80in, which is roughly 152cm by 203cm. That is very close to a UK king at 150cm by 200cm, but not identical, and the difference is enough to matter for fitted sheets.
Meanwhile a US full or double is 54in by 75in, roughly 137cm by 191cm, which sits close to a UK double at 135cm by 190cm. So the double comparison translates reasonably well across the Atlantic, while the queen comparison does not translate at all cleanly.
The practical consequence is simple: buy bedding in the same system as the mattress. Imported queen sheets on a UK king mattress will either strain or wrinkle, and neither is comfortable. When shopping UK ranges, look at the centimetre measurements rather than the name, since dimensions never lie.
On paper, 15cm sounds minor. Shared between two adults it works out at roughly 7.5cm each, about the width of a hand. In practice that margin is more noticeable than the number suggests, particularly for people who turn frequently during the night or who sleep with an arm out.
A double gives each person around 67cm of width. That is narrower than a standard single mattress at 90cm, which surprises many people when they first do the sum. Moving to a queen or UK king lifts each person to about 75cm. It does not reach single bed generosity, but it noticeably reduces the sensation of negotiating for space.
The extra 10cm of length matters separately, and it matters most for anyone approaching or over six feet. A 190cm double leaves very little room once a pillow is in place, and feet against a footboard is a common complaint. A 200cm mattress removes that problem for most adults.
A double remains a sensible size in plenty of UK homes, and it is not simply a compromise. In a room measuring around 3m by 3m or less, a double leaves usable floor space and proper walkways where a wider bed would not. Access to a wardrobe or a window should never be sacrificed for mattress width.
Doubles suit single sleepers who want room to spread out, guest rooms used occasionally, and second bedrooms that double as a study or hobby space. Bedding is the most widely available of any size and generally the most affordable, which is a genuine advantage if you like changing schemes.
Older properties with narrow doorways and turning landings also favour doubles for practical reasons. Getting a 150cm mattress up a tight Victorian staircase is achievable with a rolled mattress, but a 135cm one is simply easier. Our range of modern double fabric beds UK sale covers plenty of designs that work well in these more compact rooms.
Two adults sharing every night is the clearest reason to go wider. Sleep is easily disturbed by a partner shifting position, and additional width reduces that disturbance more effectively than most other changes. If either person is tall, the longer mattress makes the case stronger still.
The deciding factor is the room, not the preference. Add the frame width to the 150cm mattress, then allow at least 60cm of clear floor on each side you need to walk down and 70cm where a wardrobe or drawer opens. If those figures fit comfortably within your wall to wall measurement, the larger bed will work.
Marking the footprint on the floor with masking tape is a genuinely useful test. Live with the outline for a couple of days and notice whether you are stepping around it. If you are, the double is the better answer. Those going ahead will find our modern king size fabric beds UK sale and king size wooden beds UK ranges both list frame and mattress dimensions separately, which makes that measurement check straightforward.
This trips up more people than the naming does. The size quoted on a bed is the mattress size. The frame footprint is larger, and how much larger depends entirely on the design.
A slim metal or minimal wooden frame might add only 5cm on each side. A deeply upholstered frame with a padded surround can add 15cm or more. Across a bed that is 30cm of extra width, which can be the difference between a comfortable walkway and a squeeze. Ottoman bases sit somewhere in between but need clearance for the lid to open.
Always check the external dimensions on the product page rather than assuming. Also check the headboard height against your wall, particularly if there is a radiator, window sill or picture rail to clear. If space is genuinely tight, a low profile frame or a bed with no footboard opens the room up considerably.
Moving from a double to a king means replacing bedding. A double duvet is generally 200cm by 200cm, while a king duvet is around 225cm by 220cm. Using a double duvet on a king bed leaves the sides short, which is the usual reason one person wakes up uncovered.
Pillows change too. Two standard pillows sit fine on a double. On a king, two standard pillows leave a gap in the middle, so most people use two king size pillows or three standard ones. It is a small detail but it changes how complete the bed looks.
Mattress depth affects fitted sheets. Deep pocket sprung and hybrid mattresses can exceed 30cm, and a standard depth fitted sheet will keep pulling off the corners. Check the depth and buy the matching sheet rather than fighting it every week.
Once the bed size is settled, the surrounding furniture determines whether the room feels calm or crowded. On a double, a single bedside cabinet on the access side often works better than two, leaving the other side clear. On a king, a matching pair either side creates a symmetry that makes the width look intentional.
Where floor space is limited, look for slim depth cabinets or wall mounted shelves instead of full units. Vertical storage is more efficient than horizontal in small UK bedrooms: a tall narrow chest holds as much as a wide low one while occupying less floor.
Our modern bedside cabinets UK sale selection includes narrow options designed for exactly this situation, and the wider bedroom furniture UK sale range makes it easier to match finishes across bed, cabinets and drawers so a smaller room reads as coordinated rather than assembled piecemeal.
Answer three questions honestly. Does more than one adult sleep in the bed every night. Is either sleeper over about five foot ten. Does the room measure enough to take a 150cm mattress plus frame plus proper walkways.
Two or three yes answers point towards a queen or UK king. One or none points towards a double. This is a more reliable guide than aspiration, because a bed that fits the room properly improves daily life more than one that technically fits but blocks the wardrobe.
In practice, yes. UK retailers rarely use the term queen, and a mattress described as queen in Britain will usually be 150cm by 200cm, which is a UK king size.
Using UK dimensions, a queen or king is 15cm wider and 10cm longer than a double: 150cm by 200cm compared with 135cm by 190cm.
It will fit the bed but hang short at the sides. A king size duvet is the correct match for a 150cm wide mattress.
No. The frame is built to the mattress dimensions, so a 150cm mattress will not sit in a 135cm frame. Frame and mattress sizes must match.
A double is usually the better fit in rooms around 3m by 3m or smaller, since it leaves proper walkways and access to wardrobes and windows.
