What Makes This Result Specific
UK Mattresses And European Dimensions
UK mattresses often use names such as single, double, king and super king. European mattresses are commonly sold by centimetre dimensions such as 90 x 200 cm, 140 x 200 cm, 160 x 200 cm and 180 x 200 cm. The names do not match perfectly. A UK double is 135 x 190 cm, while a common European double is 140 x 200 cm. A UK king is 150 x 200 cm, while a European 160 x 200 cm mattress is often sold as a roomy double or queen-style size.
Length is a major difference. Many UK sizes under king length are 190 cm long, while European mattress sizes are often 200 cm long. That extra 10 cm can be helpful for taller sleepers but may not fit an existing UK frame. Width also matters for fitted sheets, bed bases, headboards and room layout. This converter gives the closest EU direction and warns where the match is not exact.
UK To EU Mattress Size Table
| UK Mattress | UK Dimension | Common EU Direction | Fit Warning |
|---|---|---|---|
| Single | 90 x 190 cm | 90 x 200 cm | EU is usually 10 cm longer. |
| Small double | 120 x 190 cm | 120 x 200 cm | Length differs; check frame end clearance. |
| Double | 135 x 190 cm | 140 x 200 cm | EU is wider and longer. |
| King | 150 x 200 cm | 150 x 200 cm if sold, or 160 x 200 cm | 160 cm may not fit a UK king frame. |
| Super king | 180 x 200 cm | 180 x 200 cm | Strong match in many EU ranges. |
| Emperor or larger | Varies | Usually specialist order | Use exact dimensions only. |
Frame, Sheet And Topper Checks
If you are replacing a mattress inside an existing frame, measure the frame’s internal width and length. A slatted bed frame with side rails may not accept a wider EU mattress even if the bed name sounds similar. A divan base should match the mattress footprint closely. A platform base can sometimes carry a slightly different mattress, but overhang may look poor and can affect support.
For fitted sheets, pocket depth joins width and length as a key measurement. A 140 x 200 cm EU fitted sheet may be too loose on a UK double 135 x 190 cm mattress, and it may still be too shallow if the mattress is deep. Toppers are more forgiving than mattresses because a small difference can sit on top, but straps and corners may still move if the size is far away.
Worked Mattress Examples
| Case | UK Size | EU Direction | Next Check |
|---|---|---|---|
| Replacing a UK double mattress | 135 x 190 cm. | EU 140 x 200 cm is close but larger. | Measure the frame, not only the room. |
| Buying a fitted sheet for UK king | 150 x 200 cm. | Look for exact 150 x 200 cm where possible. | Check pocket depth and topper. |
| Guest room with flexible frame | UK single. | EU 90 x 200 cm may suit taller guests. | Check headboard and footboard clearance. |
| Super king bedding | 180 x 200 cm. | EU 180 x 200 cm is often a direct match. | Still check depth for sheets. |
Depth, Bases And Bedding Layers
Length and width are only the first mattress checks. Depth can decide whether fitted sheets, protectors and toppers work. A UK double and a near EU double might both look close in plan view, but a deep pillow-top mattress can need a much deeper fitted sheet than a slim foam mattress. If you use a topper, add the topper depth to the mattress depth before choosing sheets. If you use a mattress protector with elasticated sides, check whether it is designed for the combined depth or only the mattress itself.
The bed base also matters. Slatted frames can have side rails, centre rails and end boards that restrict the exact space available. A divan base normally expects the mattress footprint to match closely. An adjustable base may need the exact compatible size because the mattress bends with the frame. A platform base may tolerate a small difference, but overhang can affect support and make the bed look unfinished. Measure inside the frame at the top, middle and foot end, because older wooden frames may not be perfectly square.
For couples, compare sleep space as well as room space. Moving from a UK double to an EU 140 x 200 cm mattress gains width and length, but it may require new sheets, protector, bed base and duvet. Moving from a UK king to a 160 x 200 cm EU size can give more width, yet it may block bedside furniture or fail to fit through a stair turn.
Before Importing A Mattress
Mattresses are expensive and awkward to return. Check delivery access, stair turns, lift size, packaging, returns, trial period and whether the mattress can be used on your bed base. Some warranties require a specific slat spacing or base type. If the mattress is rolled, check whether it can be returned after expansion. For rentals and furnished properties, check whether changing size affects existing sheets, protectors, toppers and headboard fit.
