It’s important to know what mattress size works best for your needs when shopping for a new mattress Mattress sizes vary from country to country – especially in a Europe since it’s made up of many different small countries – so it’s important to understand the differences between American and European mattress sizes. In this section, we discuss the common European mattress sizes and compare them to American standard sizes.
Single/Twin
A European single or twin mattress is 90 cm (36 inches) wide and 200 cm (78 inches) long. It’s slightly less wide and a few inches longer than an American twin mattress This mattress size is suitable for a tall-ish, average-sized person. Read our Emma mattress review for an example of a brand that makes an EU single.
Single Extra Long
This size is the same width as a single or twin mattress, but the length is extended to 220 cm (82 inches). It’s still smaller than a US twin mattress when it comes to width, but it’s much longer. It’s even longer than a California king bed! This size is ideal for taller people who need extra legroom but definitely not for those who roll around a lot while sleeping (because well, they’ll fall).
Small Double
A small double mattress is 120 cm (48 inches) wide and 200 cm (78 inches) long. It’s smaller than a US full-size mattress and three inches longer. This bed size is good for one person, but it can also be enough for two people with smaller body types.
Double
A double mattress is 140 cm (54 inches) wide and 200 cm (78 inches) long. It’s basically an American full size bed that’s three inches longer. If you’re sleeping alone, this bed will have plenty of room. This bed size is also suitable for couples. You can also get a double XL size, which is similar to a Full XL mattress.
King
A European king size mattress is 160 cm (63 inches) wide and 200 cm (79 inches) long. It’s three inches wider and one inch shorter than a US queen size mattress. We recommend this size for two average sized people to share or one hefty individual. Most couples will be able to sleep comfortably on this mattress.
Grand King
A grand king size mattress is 180 cm (71 inches) wide and 200 cm (79 inches) long. It’s close to being the same width as a California king mattress, but its length is closer to a standard king mattress. A grand king mattress can accommodate couples as well as parents who co-sleep with a child or pet.
UK King
A UK king size mattress is 152 cm (60 inches) wide and 198 cm (78 inches) long. The size of a UK king mattress is similar to that of a US queen mattress except that it’s two inches shorter. Queen-size beds are the most popular choice in the US – see our queen vs. full article – because they are ideal for couples and it’s extremely easy to find bed frames and bedding in this size.
UK Super King
A UK super king size mattress is 183 cm (72 inches) wide and 198 cm (78 inches) long. The UK super king is the same width as a California king bed and is six inches shorter. This bed size is great for couples, but we don’t recommend it you’re significantly taller than average.
