International Mattress Sizes - US, Canada, UK, EU, Australia, Asia

Last Updated November 4, 2026
Mattress sizes change from country to country, and the names don't line up: a "king" in the US, the UK, Australia and China is four different beds. This international mattress size guide lists the standard sizes in the US and Canada, the UK, Europe, Australia and Asia in centimeters and inches, with the closest US size for each, so you can compare beds, frames and sheets before you buy or move.
Quick answer
The US and Canada use inch sizes: a queen is 60 x 80 inches (152 x 203 cm) and a king is 76 x 80 inches (193 x 203 cm). The UK, Europe, Australia and most of Asia use centimeter sizes, usually 190, 200 or 203 cm long. The same name can mean very different beds: a UK king (150 x 200 cm) is about the size of a US queen, while 180 x 200 cm (UK super king, the common European and Chinese large size) is the closest thing to a global size. Always compare exact measurements, not size names.
Key Takeaways:
- The US and Canada use the same mattress sizes; Canadians often call a twin a "single" and a full a "double".
- UK mattress sizes are slightly narrower and shorter than US sizes. A UK king (150 x 200 cm) is closer to a US queen than to a US king.
- European mattresses are usually 200 cm long, 10 cm longer than UK singles and doubles. The European 180 x 200 cm size and the UK super king are identical.
- Don't shop by size name alone when buying internationally: a "king" in the US, UK, Australia and China is four different sizes.
- 180 x 200 cm is the most widely shared size: it's the UK super king, a standard European size, the usual Chinese 1.8 m bed and the South Korean large king.
- Many sizes outside the US vary by a centimeter or two between makers, so check the exact measurements before you buy sheets or a frame.
International Mattress Size Comparison Chart
Queen and king are the names that cause the most confusion. This chart shows what each one means in different parts of the world. Sizes are width x length; sizes marked "about" vary by maker.
| Region | Queen | King | Largest common size |
|---|---|---|---|
| US & Canada | 152 x 203 cm (60 x 80 in) | 193 x 203 cm (76 x 80 in) | King is the widest; California king, 183 x 213 cm (72 x 84 in), is the longest |
| UK & Ireland | No queen; the UK king fills that role | 150 x 200 cm (59.1 x 78.7 in) | Super king, 180 x 200 cm; emperor, about 200 x 200 cm, is less common |
| Europe | Names vary; most stores list centimeters only | Often 160 x 200 cm (63 x 78.7 in) | 180 x 200 cm and 200 x 200 cm |
| Australia | 153 x 203 cm (60.2 x 79.9 in) | 183 x 203 cm (72 x 79.9 in) | Super king, about 203 x 203 cm, is less common |
| China | 1.5 m bed: 150 x 200 cm (59.1 x 78.7 in) | 1.8 m bed: 180 x 200 cm (70.9 x 78.7 in) | 2.0 m bed, about 200 x 200-220 cm |
| Japan | About 160 x 195 cm (63 x 76.8 in) | About 180 x 195 cm (70.9 x 76.8 in) | King |
| South Korea | 150 x 200 cm (59.1 x 78.7 in) | 160 x 200 cm (63 x 78.7 in) | Large king, 180 x 200 cm |
| Singapore & Malaysia | 152 x 190 cm (59.8 x 74.8 in) | About 183 x 190 cm (72 x 74.8 in) | King |
| India | 60 x 72-78 in (152 x 183-198 cm) | 72 x 72-78 in (183 x 183-198 cm) | King |
Good to know
Countries that measure in centimeters set round metric sizes, like 90 x 200 cm, so their inch conversions come out as decimals (35.4 x 78.7 inches). US sizes are round numbers in inches instead, which is why a US queen works out to 152.4 x 203.2 cm. In the tables below, centimeters are rounded to the nearest whole number and inches to one decimal place.
US and Canada Mattress Sizes
The US and Canada share the same mattress sizes. Even though Canada uses the metric system, mattresses there are still made to US inch measurements, so US sheets and frames fit Canadian beds. The only real difference is the names: Canadians often call a twin a "single" and a full a "double".
| US size | Centimeters (W x L) | Inches (W x L) | Also called in Canada |
|---|---|---|---|
| Twin | 97 x 191 cm | 38 x 75 in | Single |
| Twin XL | 97 x 203 cm | 38 x 80 in | Twin XL or single XL |
| Full | 137 x 191 cm | 54 x 75 in | Double |
| Queen | 152 x 203 cm | 60 x 80 in | Queen |
| King | 193 x 203 cm | 76 x 80 in | King |
| California King | 183 x 213 cm | 72 x 84 in | California king |
38 x 75"
Twin Mattress
The twin mattress, known as a single in Canada, is the smallest standard size. It suits small apartments, children's bedrooms and bunk beds.
38 x 80"
Twin XL Mattress
The twin XL mattress is as wide as a twin but 5 inches longer. Taller sleepers like the extra legroom, and it's the usual size in college dorms.
54 x 75"
Full Size Mattress
The full size mattress, called a double in Canada, is 16 inches wider than a twin. It's a roomy choice for one adult who wants more space.
60 x 80"
Queen Mattress
The queen mattress is the most popular size in the US and Canada. It fits most couples and also suits single sleepers who like room to stretch out.
76 x 80"
King Mattress
The standard king size mattress is the widest standard size in North America. With enough bedroom space, it gives couples, kids and pets plenty of room.
72 x 84"
California King Mattress
The California king mattress trades 4 inches of width for 4 extra inches of length, so it's the pick for tall sleepers.

UK Mattress Sizes
UK mattress sizes started out in feet and are now sold in centimeters. Singles and doubles are 190 cm long, while kings and super kings are 200 cm long. UK beds are a little narrower than their US namesakes, and the names don't match: a UK king is about the width of a US queen. Ireland uses the same sizes.
| UK size | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Small Single (2'6") | 75 x 190 cm | 29.5 x 74.8 in | None; 8.5 in narrower than a twin |
| Single (3') | 90 x 190 cm | 35.4 x 74.8 in | Twin: 2.6 in narrower, about the same length |
| Small Double (4') | 120 x 190 cm | 47.2 x 74.8 in | None; between a twin and a full |
| Double (4'6") | 135 x 190 cm | 53.1 x 74.8 in | Full: about 1 in narrower, about the same length |
| King (5') | 150 x 200 cm | 59.1 x 78.7 in | Queen: about 1 in narrower, 1.3 in shorter |
| Super King (6') | 180 x 200 cm | 70.9 x 78.7 in | None; 5.1 in narrower than a king |
| Emperor (approximate) | About 200 x 200 cm | About 78.7 x 78.7 in | King: about 2.7 in wider, 1.3 in shorter |
75 x 190 cm
Small Single Mattress
The most compact UK size. It's a good fit for small rooms, bunk beds and young children.
90 x 190 cm
Single Mattress
The standard bed for one person and the most common size for kids' and teenagers' bedrooms.
120 x 190 cm
Small Double Mattress
Gives a solo sleeper more room without taking much more floor space. Two people can share it, but it's a tight squeeze.
135 x 190 cm
Double Mattress
A popular size for couples in the UK, and the closest UK match to a US full (just under an inch narrower).
150 x 200 cm
King Mattress
Gives couples more width and a bit of extra length than a double. It's close to a US queen, not a US king, so don't assume bedding will transfer.
180 x 200 cm
Super King Mattress
The most popular large size in the UK. It's about 5 inches narrower than a US king and about the width of a US California king.
200 x 200 cm
Emperor Mattress
The largest UK size, but it isn't fully standard: some makers use other lengths. Bedding is harder to find, so check the exact size first.
Tip
Some UK stores also sell European sizes, so check whether a listing says 190 or 200 cm long before you order sheets. Comparing a UK super king with a US king? Our super king vs king guide walks through the difference.
European (EU) Mattress Sizes
Continental Europe keeps it simple: mattresses are sold by their exact size in centimeters, and the standard length is 200 cm. Names like single, double or king are shorthand that changes from store to store, so the centimeters are what matter. The four sizes below are the most common.
| EU size | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| EU Single | 90 x 200 cm | 35.4 x 78.7 in | Twin XL: 2.6 in narrower, 1.3 in shorter |
| EU Double | 140 x 200 cm | 55.1 x 78.7 in | Full: about 1 in wider, 3.7 in longer |
| EU King | 160 x 200 cm | 63 x 78.7 in | Queen: 3 in wider, 1.3 in shorter |
| EU Grand King | 180 x 200 cm | 70.9 x 78.7 in | None; 5.1 in narrower than a king |
| Also sold: narrow single | 80 x 200 cm | 31.5 x 78.7 in | None; 6.5 in narrower than a twin XL |
| Also sold: wide single | 100 x 200 cm | 39.4 x 78.7 in | Twin XL: 1.4 in wider, 1.3 in shorter |
| Also sold: small double | 120 x 200 cm | 47.2 x 78.7 in | None; between a twin XL and a full |
| Also sold: extra-wide double | 200 x 200 cm | 78.7 x 78.7 in | King: 2.7 in wider, 1.3 in shorter |
90 x 200 cm
EU Single Mattress
The same width as a UK single but 10 cm longer, which makes it a better fit for taller sleepers.
140 x 200 cm
EU Double Mattress
Wider and longer than a UK double, and sized between a US full and a US queen. A comfortable option for couples who don't need a large bed.
160 x 200 cm
EU King Mattress
Sits between a US queen and a US king in width. A good choice for couples who want more space without going up to the largest size.
180 x 200 cm
EU Grand King Mattress
A large size that matches the UK super king exactly, so bedding made for one will fit the other. Some stores also sell 200 x 200 cm.
Good to know
Many European double beds hold two single mattresses side by side, for example two 90 x 200 cm mattresses on a 180 cm frame, so each sleeper can choose their own feel. You'll also see 190 cm and 210 cm lengths in some countries and stores.
Australia Mattress Sizes
Australian mattress sizes are close to US sizes but not identical, with small differences in width and length. Australia also has a size you won't find in the US: the king single. Some sizes vary by a centimeter between makers, so the ranges below are approximate.
| Australian size | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single | 92 x 187-188 cm | 36.2 x 73.6-74 in | Twin: about 2 in narrower, 1 in shorter |
| Long Single (single XL) | 92 x 203 cm | 36.2 x 79.9 in | Twin XL: about 2 in narrower, same length |
| King Single | 106-107 x 203 cm | 41.7-42.1 x 79.9 in | None; about 4 in wider than a twin XL |
| Double | 138 x 187-188 cm | 54.3 x 73.6-74 in | Full: about the same width, 1 in shorter |
| Queen | 153 x 203 cm | 60.2 x 79.9 in | Queen: practically the same |
| King | 183 x 203 cm | 72 x 79.9 in | None; California king width, 4 in shorter |
| Super King (less common) | About 203 x 203 cm | About 79.9 x 79.9 in | None; about 4 in wider than a king |
92 x 187 cm
Single Mattress
Close to a US twin but slightly narrower and a touch shorter. A good fit for children's bedrooms and small spaces.
92 x 203 cm
Long Single Mattress
Adds length for taller sleepers while keeping the single's width. It's the Australian take on a US twin XL.
106 x 203 cm
King Single Mattress
Wider than a single but narrower than a double. A popular choice for older children and teenagers who want more room.
138 x 187 cm
Double Mattress
About the width of a US full but slightly shorter. Works well for single adults who want extra space.
153 x 203 cm
Queen Mattress
The most popular size for couples, just like in the US, and practically the same size as a US queen.
183 x 203 cm
King Mattress
The same width as a US California king but 4 inches shorter, and about 4 inches narrower than a US king.
203 x 203 cm
Super King Mattress
A square bed that gives couples the most space in every direction. It's less common, so bedding can be harder to find.
Good to know
New Zealand shares many Australian sizes, but its king and super king are different: a New Zealand king is narrower (about 165 x 203 cm), and a New Zealand super king is about the size of an Australian king. Check the centimeters if you're comparing the two.
Asia Mattress Sizes
Asia doesn't have one mattress standard. Sizes vary by country, and many sellers list their own measurements, so treat the tables below as common sizes rather than fixed rules. We've broken it down into China and East Asia (including Japan and South Korea), Southeast Asia, and India.
China & East Asia
In mainland China, beds are usually named by their width in meters (a "1.5 m bed" or "1.8 m bed") rather than queen or king, and most are 200 cm long, matching European lengths. Exact sizes vary by maker.
| China size (approximate) | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single (0.9 m) | 90 x 190-200 cm | 35.4 x 74.8-78.7 in | Twin or twin XL: 2.6 in narrower |
| Small Double (1.2 m) | 120 x 200 cm | 47.2 x 78.7 in | None; between a twin XL and a full |
| Queen (1.5 m) | 150 x 200 cm | 59.1 x 78.7 in | Queen: about 1 in narrower, 1.3 in shorter |
| King (1.8 m) | 180 x 200 cm | 70.9 x 78.7 in | None; 5.1 in narrower than a king |
| Large King (2.0 m) | 200 x 200-220 cm | 78.7 x 78.7-86.6 in | King: about 2.7 in wider |
- Single: about the width of a UK or EU single. At 200 cm long it matches the EU single; 190 cm versions match the UK single.
- Small double: the same width as a UK small double, but 10 cm longer. Best for one person who wants extra space, though it can fit two in a pinch.
- Queen (1.5 m): the same size as a UK king. It's slightly narrower and shorter than a US queen, so US bedding won't always be a clean fit.
- King (1.8 m): matches the EU 180 x 200 cm size and the UK super king, so bedding made for either will fit.
Japan
Japanese mattresses are usually 195 cm long (some makers use 200 cm), and widths vary by a few centimeters between brands. Japan also has a semi-double size between a single and a double.
| Japan size (approximate) | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single | 97 x 195 cm | 38.2 x 76.8 in | Twin: same width, 1.8 in longer |
| Semi-Double | 120 x 195 cm | 47.2 x 76.8 in | None; between a twin and a full |
| Double | 140 x 195 cm | 55.1 x 76.8 in | Full: about 1 in wider, 1.8 in longer |
| Queen | 160 x 195 cm | 63 x 76.8 in | Queen: 3 in wider, 3.2 in shorter |
| King | 180 x 195 cm | 70.9 x 76.8 in | None; 5.1 in narrower and 3.2 in shorter than a king |
South Korea
South Korean mattresses are 200 cm long, but the names are shifted compared with China: a Korean king is 160 cm wide, and the 180 cm size is called a large king. The super single is a popular size for one sleeper.
| South Korea size (approximate) | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single | 100 x 200 cm | 39.4 x 78.7 in | Twin XL: 1.4 in wider, 1.3 in shorter |
| Super Single | 110 x 200 cm | 43.3 x 78.7 in | None; 5.3 in wider than a twin XL |
| Queen | 150 x 200 cm | 59.1 x 78.7 in | Queen: about 1 in narrower, 1.3 in shorter |
| King | 160 x 200 cm | 63 x 78.7 in | Queen: 3 in wider, 1.3 in shorter |
| Large King | 180 x 200 cm | 70.9 x 78.7 in | None; 5.1 in narrower than a king |
Hong Kong and Taiwan have their own local sizes, so check the exact measurements with the seller there.
Southeast Asia (Singapore & Malaysia)
Singapore and Malaysia share the same sizes, based on feet: 3, 3.5, 5 and 6 feet wide by about 6 feet 3 inches (190 cm) long. That makes them shorter than Chinese, European and US queen and king sizes.
| Singapore & Malaysia size | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single | 91 x 190 cm | 35.8 x 74.8 in | Twin: 2.2 in narrower, about the same length |
| Super Single | 107 x 190 cm | 42.1 x 74.8 in | None; about 4 in wider than a twin |
| Queen | 152 x 190 cm | 59.8 x 74.8 in | Queen width, 5.2 in shorter |
| King (approximate) | 182-183 x 190 cm | 71.7-72 x 74.8 in | None; California king width, 9.2 in shorter |
- Single: close to a UK single in both width and length.
- Super single: wider than a standard single but narrower than a queen, so it's popular with solo sleepers who want more room. It's about the width of the Australian king single, just shorter.
- Queen: the same width as a US queen but about 13 cm (5 inches) shorter, so US queen sheets will be loose at the ends.
- King: about the width of a US California king but 9 inches shorter, so bedding won't transfer between the two.
India
India stands out because mattresses are usually made and sold in inches, and listings often give the length first (for example, "72 x 36 inches"). Lengths of 72, 75 and 78 inches are all common, so the ranges below vary by maker. You may also see 48-inch-wide mattresses listed as "diwan" size, after the daybed-style diwan.
| India size (approximate) | Centimeters (W x L) | Inches (W x L) | Closest US size |
|---|---|---|---|
| Single | 91 x 183-198 cm | 36 x 72-78 in | Twin: 2 in narrower |
| Double (diwan) | 122 x 183-198 cm | 48 x 72-78 in | None; between a twin and a full |
| Queen | 152 x 183-198 cm | 60 x 72-78 in | Queen width, 2-8 in shorter |
| King | 183 x 183-198 cm | 72 x 72-78 in | None; California king width, 6-12 in shorter |
- Single: close to a US twin in width. The length varies, so check the exact dimensions before buying bedding.
- Double or diwan: sits between a single and a queen in width, a handy size for one sleeper or a guest bed.
- Queen: the same width as a US queen, but 2 to 8 inches shorter, so US queen fitted sheets will be loose at the ends.
- King: the same width as a US California king but shorter, and 4 inches narrower than a US king.
How to Convert Mattress Sizes Between Centimeters and Inches
One inch is exactly 2.54 centimeters. To turn centimeters into inches, divide by 2.54; to turn inches into centimeters, multiply by 2.54. For example, a 160 x 200 cm mattress is 160 / 2.54 = 63 inches wide and 200 / 2.54 = 78.7 inches long.
2.54 cmin 1 inch
78.7 in200 cm, the European length
74.8 in190 cm, the UK single and double length
203 cm80 in, the US queen and king length
Tip
Always write sizes as width x length, and check which order a listing uses. Most countries put width first, but some sellers (especially in India) put the length first.
Buying a Mattress or Bedding in Another Country
Whether you're moving abroad, buying sheets online from another country or furnishing a vacation home, a few checks save you from a mattress that doesn't fit its frame or sheets that won't stay on.
-
Measure what you have
Measure the mattress width, length and depth with a tape measure. Write the numbers down in both centimeters and inches.
-
Compare numbers, not names
A queen or king in one country can be a very different size somewhere else. Match the exact measurements, and allow for a centimeter or two of difference between makers.
-
Check the bed frame
Frames are sized to local mattresses. A US queen (152 x 203 cm) on a European 160 x 200 cm frame would leave a gap at the sides and hang over the end, so plan on a new frame or a new mattress.
-
Plan your bedding
A fitted sheet that's an inch or two too big usually works; one that's too small won't stay on. Check the pocket depth too, since mattress thickness varies. Our bed sheet size guide lists US sheet sizes.
-
Moving to or from the US?
Bringing a mattress overseas is rarely worth it, because local frames and sheets won't match. Many people buy a mattress in the local size after they move.
