UAE Mattress Size Guide: UK vs USA vs EU Sizes
A King mattress in the UAE is not the same bed as a King in London, and neither matches a King in New York. Three sizing systems are in daily use here, on the same websites, sometimes inside the same product page.
This ultimate UAE mattress size guide sets them against each other in centimetres. Get it right first time. If you are earlier in the process, our complete guide to buying a mattress in the UAE covers the whole decision in order.
Why three systems ended up in one market
British sizing arrived with UK retail conventions. European sizing came with EU manufacturing. American sizing came with US brands and with expat shoppers who learned the names before they arrived.
None of the three was adjusted on arrival. A size name therefore records which market a retailer took its vocabulary from. It says nothing about the actual width of the bed.
Mattress size guide: UK vs USA vs EU sizes explained
Five things in that table cause most of the trouble.
150 x 200 and 152 x 203 are the near misses. A UK King and a US Queen are the closest pair across the two systems, which is why retailers map one onto the other. They are not the same bed. Two centimetres of width will not change how you sleep. Three centimetres of length is enough to lift a fitted corner overnight, because sheets grip by tension.
193 x 203 is a US King and appears on no British or European chart. It is wider and longer than anything the UK ladder offers below Emperor.
160 x 200 is the Euro King, often called the IKEA King, and standard across continental Europe. It sits 10 cm wider than a UK King and 20 cm narrower than a UK Super King, which is why a European frame and a British mattress so rarely meet.
180 x 200 is the one genuine match. A UK Super King and a European Grand King are identical. It is also the size most UAE retailers, including us, group under the name King, which is where the confusion lands hardest here.
Length is not constant. UK sizes below King run 190 cm, European run 200, American run 203. Assuming a shared length across a chart is its own source of error.
The trap inside a single product page
On our own site, the collection name and the size option can use different vocabulary for the same bed. Our king size range is 180 x 200, which British retailers sell as a Super King.
> TMS size tip. Always select your mattress using the dimensions in centimetres. At The Mattress Store, a collection name and the individual size option may use different naming conventions for the same bed.
How to measure your bed for the correct mattress size
Measure the frame, not the old mattress. An old mattress may have spread, compressed, or been the wrong size from the start, which is how one mistake gets inherited by the next bed.
Measure the internal dimensions, width and length. Frames are described by the mattress they take rather than by their own outside measurements, so the number in a frame listing is not the number you need.
Measure at the base, not the rim. Some frames narrow toward the top, and a mattress that clears the rim can still bind lower down.
Check the depth the frame allows. A deep mattress inside a high-sided frame sits below the rail and makes the bed awkward to get out of. A shallow one in a low frame sits proud and slides.
Write both numbers down and buy to them, not to the name on your old mattress and not to the name you used in your last country.
Small manufacturing variations can occur, so check the dimensional tolerance specified by the mattress manufacturer. A significantly oversized mattress may bind or overhang, wearing unevenly along an unsupported edge, while an undersized one leaves a gap and moves within the frame.
How to match a bed and mattress size in the UAE
Matching is a different job from measuring, and three constraints decide it.
The room decides more often than the bed does. Leave 60 to 70 cm of clear floor on each side you walk down, and check wardrobe doors and drawers still open fully with the bed in place. In more compact bedrooms, common across Dubai, Sharjah, Abu Dhabi and Al Ain, walkway clearance often determines the practical size. In larger rooms you have more freedom to prioritise sleeping space.
Bedding follows the dimension, not the name. Before committing to an unusual size, check that fitted sheets and a protector in that dimension are easy to buy here. A protector earns its place because fine dust works down into comfort layers, and most manufacturers treat staining as grounds for invalidating a warranty claim.
The base has to suit the mattress, and requirements vary by manufacturer. Englander's warranty, as one example, sets specific support conditions for innerspring mattresses: no resting straight on open slats, a solid platform laid across them instead, and rigid centre support reaching the floor. Always check the conditions for the specific mattress you are buying. Our guide on matching a bed and mattress covers fit in more detail.
Access decides what can arrive. A large mattress does not bend. Take the lift's internal depth and door width, then trace the route from the entrance to the bedroom for the narrowest corner. Roll-packed delivery clears gaps a flat one will not, so ask which applies.
Width per sleeper, the number that matters
On 150 x 200, two people have 75 cm each, less than the 90 cm one adult gets alone in a single. On 180 x 200 they have 90 cm each. On 200 x 200, a metre each.
Length is the other half. If either of you is over about 185 cm, a 200 cm mattress leaves little margin once a pillow is in place.
Which size should you buy?
Two adults with sufficient room, roughly 310 cm wall to wall or more. Consider 180 x 200, which gives each sleeper about 90 cm of width, substantially more personal space than a 150 x 200. How much a partner's movement reaches you also depends on construction, so weigh that alongside width.
Two adults, a smaller bedroom. 150 x 200. The walkway is worth more than the extra 15 cm per person.
A child's bed. 90 x 200 rather than 90 x 190. The extra 10 cm can offer more room for growth and may reduce the need to change sizes later.
An inherited or imported frame. Measure first, then buy to the centimetre. If it is 160 cm internally, a 150 cm mattress leaves a 10 cm gap that swallows bedding and lets the mattress slide.
Where a smaller size is genuinely fine
Sizing up is not automatically the better buy.
Guest rooms. Guests sleep in the bed a handful of nights a year. A 150 x 200 fits rooms a larger bed would swamp, and the reclaimed floor serves better for the other fifty-one weeks.
Second bedrooms carrying a desk or wardrobe. The furniture you use daily beats the mattress width you notice occasionally.
Short leases. A larger mattress is the least portable thing in the flat, and the bedding moves with it.
Any room where the walkway would drop 60 cm below. Edging past a bed every night is the worst outcome, every time.
Before you order
-
Measure the frame internally, at the base, both dimensions.
-
Write the numbers in centimetres.
-
Match those numbers on the product page, not the size name.
-
Check the depth against your frame sides and your sheets.
-
Confirm bedding is available in that dimension here.
-
Confirm any slatted base carries a solid platform, and that a centre leg reaches the floor.
-
Measure the lift, the door width and the tightest corner on the route.
Where to go from here
The whole of this ultimate UAE mattress size guide reduces to one habit: buy to the centimetre figure, never to the word. Measure the frame at the base, leave yourself a walkway, and check the bedding exists before you fall for an unusual size.
Because all sales are final, the size is worth confirming twice. The full mattress collection lists the centimetre figure against every option, and the single, queen, king and super king collections each carry their own dimensions. If your frame is awkward, bring the measurements to one of our showrooms, including City Centre Al Zahia in Sharjah, and we will work it out with you.
Frequently asked questions
What size is a King mattress in the UAE?
UAE retailers use a mixture of UK, European and US sizing conventions. Under UK sizing a King is typically 150 x 200 cm and a Super King 180 x 200 cm. At The Mattress Store some collections group 180 x 200 under King, so always check the dimensions shown on the product page.
Is a UK King the same as a US Queen?
No, they are close equivalents rather than the same mattress. A UK King is 150 x 200 cm and a US Queen is 152 x 203 cm, so the American size is about 2 cm wider and 3 cm longer. Irrelevant for comfort, significant for fitted sheets.
What is the largest mattress size sold here?
Across our range the largest is 200 x 200 cm, which the size option labels UK Emperor and the collection calls Super King. It gives two sleepers a metre each, and fitted sheets at that dimension are still straightforward to buy locally, which is not true of every oversized bed.
How do I measure my bed for a new mattress?
Measure the frame internally, both width and length, at the base rather than the rim. Do not measure your old mattress, since it may have spread or been the wrong size originally. Write both numbers in centimetres and buy to those figures.
