The most common mattress sizes in North America include Twin (38″ x 75″), Twin XL (38″ x 80″), Full or Double (54″ x 75″), Queen (60″ x 80″), King (76″ x 80″), and California King (72″ x 84″). The Queen size is the most popular choice for couples, offering a balance of space and room compatibility, fitting well in average 10′ × 10′ bedrooms. For couples seeking more space, the King mattress provides 38″ of personal width per person, compared to 30″ on a Queen, making it ideal for those with a 12′ × 12′ room or larger. The California King, while narrower, offers greater length at 84″, making it suitable for taller individuals or those who prefer extra legroom.
Smaller sizes like the Twin and Twin XL are ideal for children, single adults under 6′ tall, or guest rooms, with Twin XL being better suited for taller teens or college dorms due to its increased length. The Full mattress is appropriate for single adults or smaller rooms, though it may feel cramped for couples. Specialty sizes include the Split Queen (30″ x 80″ per half) and Split California King (36″ x 84″ per half), designed for adjustable bed frames where each side can move independently. Other niche sizes include RV-specific options like the Short Queen (60″ x 75″) and Short King (72″ x 75″), as well as oversized options such as the Alaskan King (108″ x 108″) and Wyoming King, which require custom bedding and are less commonly available.
For room planning, a Queen mattress requires a minimum room size of 10′ × 10′, while a King needs at least 12′ × 12′ to allow for comfortable walking space on all sides. It is recommended to allow 24–30″ of walking space around the bed to accommodate movement and furniture placement. Bed frames also vary in footprint; for example, a Queen mattress typically fits within a 65″ × 84″ frame, while a King fits within an 81″ × 84″ frame. In other regions, bed sizes differ: the UK and Ireland use sizes like Small Single, Double, and King, while European standards include EU Single (90 x 200 cm) and Grand King (180 x 200 cm).

emsk Ever Man Should Know The Mattress Sizes
I'm American and I assume in Europe, bed sizes aren't called "California King", so I'm curious, what are the names for bed sizes in your country?
Malm Bed mattress Sizes
I bought the queen size version and it works just fine with a mattress I got from a third party ... The bed holds up just fine with the mattress and two people on it.
Slightly related, I absolutely love the MALM pull up storage bed and would strongly recommend it to anyone.
