This international mattress size guide covers all global sizes, including the US, Canada, the UK, the EU, Australia, and Asia, with charts for easy comparison.
Key Takeaways:
US and Canada share the same mattress sizes, with the only real difference being that Canadians refer to the twin as a 'single' bed and the full as a 'double' bed.
| US/CANADA MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Twin (single) | 38 x 75 inches | 3.17 x 6.25 feet | 96.52 x 190.5 cm |
| Twin XL | 38 x 80 inches | 3.17 x 6.67 feet | 96.52 x 203.2 cm |
| Full (double) | 54 x 75 inches | 4.5 x 6.25 feet | 137.16 x 190.5 cm |
| Queen | 60 x 80 inches | 5 x 6.67 feet | 152.4 x 203.2 cm |
| King | 76 x 80 inches | 6.33 x 6.67 feet | 193.04 x 203.2 cm |
| California King | 72 x 84 inches | 6 x 7 feet | 182.88 x 213.36 cm |
The twin mattress, also known as a single mattress in Canada, is the smallest standard size available. Twin beds measure 38 inches in width and 75 inches in length, making them ideal for small apartments, children's bedrooms, and bunk beds.
If you need a little extra legroom, the twin XL mattress is the way to go. It offers the same width as the standard twin, but adds an extra 5 inches in length, measuring 38 inches by 80 inches. This size is preferred by taller individuals and is commonly found in college dorm rooms.
The full size mattress, also known as a double mattress in Canada, measures 54 inches in width and 75 inches in length. It's a great choice for single sleepers, especially adults, who want more space than a twin.
The queen mattress is the most popular choice in the US and Canada, offering a comfortable 60 inches in width and 80 inches in length. It's perfect for couples sharing the bed. It also works well for single sleepers who like more room to stretch out.
The standard king size mattress is the largest in the US and Canada, measuring a generous 76 inches in width and 80 inches in length. If you've got enough bedroom space, this size ensures that both you and your partner have ample room for a good night's sleep. The king can also accommodate families who co-sleep.
For those who desire even more length than a king (but at the cost of a little width), there's the California king mattress. It measures 72 inches wide and 84 inches long, and is recommended for couples/families with tall sleepers.
UK mattress sizes are narrower than US sizes, and the names don't always match up. A UK king, for instance, is closer in width to a US queen.
| UK MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Small Single | 29.5 x 74.8 inches | 2.46 x 6.23 feet | 75 x 190 cm |
| Single | 35.4 x 74.8 inches | 2.95 x 6.23 feet | 90 x 190 cm |
| Small Double | 47.2 x 74.8 inches | 3.94 x 6.23 feet | 120 x 190 cm |
| Double | 53.1 x 74.8 inches | 4.43 x 6.23 feet | 135 x 190 cm |
| King | 59.1 x 78.7 inches | 4.92 x 6.56 feet | 150 x 200 cm |
| Super King | 70.9 x 78.7 inches | 5.91 x 6.56 feet | 180 x 200 cm |
| Emperor | 78.7 x 78.7 inches | 6.56 x 6.56 feet | 200 x 200 cm |
The small single is the most compact option, measuring 75 x 190 cm (29.5 x 74.8 inches). It's a good fit for small rooms and bunk beds.
The UK single measures 90 x 190 cm (35.4 x 74.8 inches). It's the standard choice for one person, and the most common size for kids' and teenagers' bedrooms.
At 120 x 190 cm (47.2 x 74.8 inches), the small double gives a solo sleeper more room without taking up too much floor space. It can fit two people, but it's a tight squeeze.
The double measures 135 x 190 cm (53.1 x 74.8 inches) and is the most popular size for couples in the UK. It's close to a US full, just slightly wider.
The UK king measures 150 x 200 cm (59.1 x 78.7 inches) and gives couples more width and a bit of extra length. Worth noting: it's closer to a US queen in width, not a US king, so don't assume bedding will transfer between the two.
At 180 x 200 cm (70.9 x 78.7 inches), the super king is the most popular large-size option in the UK. It's roughly comparable to a US king, though a few inches narrower.
The emperor measures 200 x 200 cm (78.7 x 78.7 inches), making it the largest standard UK size. It's less common and harder to find bedding for, but gives couples the most space of any option on this list.
EU mattress sizes are simpler. There are fewer options, and they tend to be longer than UK sizes while sitting between UK and US widths.
| EUROPEAN MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| EU Single | 35.4 x 78.7 inches | 2.95 x 6.56 feet | 90 x 200 cm |
| EU Double | 55.1 x 78.7 inches | 4.59 x 6.56 feet | 140 x 200 cm |
| EU King | 63 x 78.7 inches | 5.25 x 6.56 feet | 160 x 200 cm |
| EU Grand King | 70.9 x 78.7 inches | 5.91 x 6.56 feet | 180 x 200 cm |
The EU single measures 90 x 200 cm (35.4 x 78.7 inches). It's the same width as a UK single but 10 cm longer, making it a better fit for taller sleepers.
At 140 x 200 cm (55.1 x 78.7 inches), the EU double is wider than a UK double and closer in size to a US queen. It's a comfortable option for couples who don't need a large bed.
The EU king measures 160 x 200 cm (63 x 78.7 inches), sitting between a US queen and a US king in width. It's a good choice for couples who want more space without going up to the largest size.
At 180 x 200 cm (70.9 x 78.7 inches), the EU grand king is the largest standard European size. It's the same dimensions as a UK super king, so bedding made for one will fit the other.
Australian mattress sizes are close to US sizes but not identical. There are a few small differences in both width and length across most sizes. Australia also has a couple of unique sizes you won't find elsewhere.
| AUSTRALIA MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Single | 36.2 x 74 inches | 3.02 x 6.17 feet | 92 x 188 cm |
| Long Single (single XL) |
36.2 x 79.9 inches | 3.02 x 6.66 feet | 92 x 203 cm |
| King Single | 42.1 x 79.9 inches | 3.51 x 6.66 feet | 107 x 203 cm |
| Double | 54.3 x 74 inches | 4.53 x 6.17 feet | 138 x 188 cm |
| Queen | 60.2 x 79.9 inches | 5.02 x 6.66 feet | 153 x 203 cm |
| King | 72 x 79.9 inches | 6 x 6.66 feet | 183 x 203 cm |
| Super King | 79.9 x 79.9 inches | 6.66 x 6.66 feet | 203 x 203 cm |
The Australian single measures 92 x 188 cm (36.2 x 74 inches). It's close to a US twin but slightly wider and a touch shorter. A good fit for children's bedrooms and small spaces.
At 92 x 203 cm (36.2 x 79.9 inches), the long single adds extra length for taller sleepers while keeping the same width as the standard single. It's similar to a US twin XL.
The king single is unique to Australia, measuring 107 x 203 cm (42.1 x 79.9 inches). It's wider than a standard single but narrower than a double, making it a popular choice for older children and teenagers who want more room.
The Australian double measures 138 x 188 cm (54.3 x 74 inches). It's close to a US full in width but slightly shorter in length. Works well for single adults who want extra space.
At 153 x 203 cm (60.2 x 79.9 inches), the Australian queen is the most popular size for couples, just like in the US. It's slightly wider than a US queen and a touch longer.
The Australian king measures 183 x 203 cm (72 x 79.9 inches). It's the same width as a US California king but shorter in length, giving couples plenty of space without going up to the super king.
At 203 x 203 cm (79.9 x 79.9 inches), the super king is the largest standard Australian size. It's a square mattress, giving couples maximum space in every direction.
Asia doesn't have one unified mattress standard. Sizes vary by country and region, so we've broken it down into three separate sections: China and East Asia, Southeast Asia, and India.
Across mainland China, South Korea, and Hong Kong, standard lengths are locked to a long 200 cm (78.7 inches), matching European lengths but varying in width.
| CHINA/EAST ASIA MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Single | 35.4 x 78.7 inches | 2.95 x 6.56 feet | 90 x 200 cm |
| Small Double | 47.2 x 78.7 inches | 3.94 x 6.56 feet | 120 x 200 cm |
| Queen | 59.1 x 78.7 inches | 4.92 x 6.56 feet | 150 x 200 cm |
| King | 70.9 x 78.7 inches | 5.91 x 6.56 feet | 180 x 200 cm |
The single measures 90 x 200 cm (35.4 x 78.7 inches). It's the same size as an EU single, and a bit longer than both the UK and Australian singles.
At 120 x 200 cm (47.2 x 78.7 inches), the small double is the same width as a UK small double but 10 cm longer. It's best for one person who wants extra space, though it can fit two in a pinch.
The queen measures 150 x 200 cm (59.1 x 78.7 inches), which is the same as a UK king. It's slightly narrower than a US queen and a bit shorter, so US bedding won't always be a clean fit.
At 180 x 200 cm (70.9 x 78.7 inches), the king is the largest standard size in China and East Asia. It matches the EU grand king and the UK super king in dimensions, so bedding made for either of those will fit.
Singapore and Malaysia share an identical sizing standard inherited from historical British influence. Their standard length is a compact 190 cm (74.8 inches), making them a bit shorter than China and Euro sizes.
| SOUTHEAST ASIA MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Single | 35.8 x 74.8 inches | 2.98 x 6.23 feet | 91 x 190 cm |
| Super Single | 42.1 x 74.8 inches | 3.51 x 6.23 feet | 107 x 190 cm |
| Queen | 59.8 x 74.8 inches | 4.99 x 6.23 feet | 152 x 190 cm |
| King | 71.7 x 74.8 inches | 5.97 x 6.23 feet | 182 x 190 cm |
The single measures 91 x 190 cm (35.8 x 74.8 inches), close to a UK single in both width and length.
At 107 x 190 cm (42.1 x 74.8 inches), the super single is unique to this region. It's wider than a standard single but narrower than a queen, making it a popular choice for solo sleepers who want more room. It's similar in width to the Australian king single, just shorter in length.
The queen measures 152 x 190 cm (59.8 x 74.8 inches). It's close to a US queen in width but about 10 cm shorter in length, so US bedding may not fit well.
At 182 x 190 cm (71.7 x 74.8 inches), the king is the largest standard size in Singapore and Malaysia. It's similar in width to a US California king but noticeably shorter, so bedding won't transfer between the two.
India stands out because manufacturers natively use Inches rather than centimeters as the baseline design standard. They also offer a unique local variant called the Diwan (a wide single/daybed format).
| INDIA MATTRESS SIZE | DIMENSION IN INCHES (Width x Length) |
DIMENSION IN FEET (Width x Length) |
DIMENSION IN CM (Width x Length) |
|---|---|---|---|
| Single | 36 x 72-78 inches | 3 x 6-6.5 feet | 91.4 x 182.8-198.1 cm |
| Diwan (double) | 48 x 72-78 inches | 4 x 6-6.5 feet | 121.9 x 182.8-198.1 cm |
| Queen | 60 x 75-78 inches | 5 x 6.25-6.5 feet | 152.4 x 190.5-198.1 cm |
| King | 72 x 75-78 inches | 6 x 6.25-6.5 feet | 182.8 x 190.5-198.1 cm |
The Indian single measures 36 x 72-78 inches (91.4 x 182.8-198.1 cm). The width is close to a US twin, but the variable length means you'll want to check the exact dimensions before buying bedding.
The Diwan is a uniquely Indian format, measuring 48 x 72-78 inches (121.9 x 182.8-198.1 cm). It sits between a single and a queen in width, and is traditionally used as a daybed or a seating place as much as a sleeping surface.
The Indian queen measures 60 x 75-78 inches (152.4 x 190.5-198.1 cm). The width matches a US queen exactly, but the length can vary, so US queen bedding may fit on the longer end but not always on the shorter end.
The Indian king measures 72 x 75-78 inches (182.8 x 190.5-198.1 cm). It's the same width as a US California king but shorter in length, and like the other sizes, comes with some length variation depending on the manufacturer.
