A double bed in the UK measures 135cm wide by 190cm long, which converts to 4ft 6in by 6ft 3in. That is the standard mattress size, and it has been consistent across British manufacturers for decades. The bed frame itself will be larger, usually adding between 5cm and 20cm to each dimension depending on the design.<\/p>\n
Split between two sleepers, 135cm gives each person 67.5cm of width. For context, a standard single mattress is 90cm wide, so two adults in a double each have less room than they would in a single bed. That single fact explains most of what follows.<\/p>\n
The 135cm by 190cm figure describes the mattress. When you are measuring a room, the frame is what matters.<\/p>\n
A slim metal frame might add only 4cm to the width. A wooden frame with substantial side rails typically adds 8cm to 12cm. An upholstered frame with padded sides can add 15cm or more, and a wing headboard design adds width at the head end specifically. Length increases in the same way, particularly where there is a footboard.<\/p>\n
Divan bases are the closest match to mattress size, usually within 2cm. This is why divans remain popular in genuinely tight rooms even though the styling is less distinctive.<\/p>\n
Always check the listed external dimensions rather than assuming. Every double bed at Furniture in Fashion<\/a> states the overall frame measurements alongside the mattress size for this reason.<\/p>\n The working guideline is 60cm of clear floor on each side you use for access, and preferably at the foot as well. Applied to a double, that means a room of about 2.7m by 3m accommodates the bed with usable walkways on both sides.<\/p>\n You can fit a double into a smaller room by pushing one long side against a wall. That gives one clear 60cm walkway and turns the bed into a single access design, which works for solo sleepers and is a common arrangement in box rooms.<\/p>\n Do not forget the door. A standard internal door needs about 76cm of clear arc, and a wardrobe door needs roughly its own width in floor space. These two constraints determine bed placement in small bedrooms far more often than the bed’s own dimensions do.<\/p>\n Bed height is the dimension people rarely check and often regret. Total height depends on frame, base and mattress depth combined, and the range across the market is wide.<\/p>\n Low platform frames can put the mattress top at around 40cm from the floor. Traditional divans with a deep mattress reach 65cm or higher. For most adults, a mattress top between 50cm and 60cm feels natural, allowing you to sit with feet flat on the floor and knees at roughly a right angle.<\/p>\n Height affects the room visually too. A lower bed leaves more visible wall above it and makes a low ceilinged bedroom feel taller. A higher bed feels more substantial but can dominate a small space and makes bedside table height harder to match.<\/p>\n It depends heavily on the mattress rather than the size alone. On an older open sprung mattress, two people at 67.5cm each will feel every movement the other makes, because the springs are linked. On a good pocket sprung or hybrid mattress, the same width feels considerably more spacious because motion transfer is much reduced.<\/p>\n Sleeping style matters too. Two people who sleep on their sides in similar positions manage a double comfortably for years. If one person sleeps on their front with an arm out, or moves frequently, the width becomes the limiting factor quickly.<\/p>\n If you are staying with a double and finding it tight, a mattress upgrade is usually the cheaper and more effective fix than a size change. Our modern mattresses UK sale<\/a> range includes pocket sprung double options that make a measurable difference to partner disturbance.<\/p>\n The next size up in the UK is a king at 150cm by 200cm. That adds 15cm of width, which splits to 7.5cm each, plus 10cm of length. The length increase is often the more significant gain for taller sleepers.<\/p>\n A king needs a room closer to 3m by 3.4m to keep both walkways clear. If your bedroom is under 3m in either direction, a double with proper circulation will feel better than a king with 40cm walkways.<\/p>\n Staircases matter as well. Older terraced and semi detached properties frequently have turns that a king headboard cannot navigate. Doubles are easier to get upstairs, and flat packed designs easier still.<\/p>\n At double size, the frame becomes the main piece of furniture in most bedrooms, so material and proportion carry real weight.<\/p>\n Fabric upholstered frames soften a room and absorb sound, which suits bedrooms with hard floors and minimal soft furnishings. Our modern double fabric beds UK sale<\/a> range covers everything from low slung minimal designs to tall buttoned headboards.<\/p>\nWhat room size a double needs<\/h3>\n
