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 Twin size is ideal for children, single sleepers, or small spaces, while the Twin XL offers extra length for taller individuals, such as college students. A Full mattress provides more width than a Twin, suitable for solo sleepers who want additional room, though it may feel cramped for couples. The Queen size is the most popular choice for couples and taller single sleepers, offering a balance of space and room efficiency. The King size provides maximum space for couples or families, with a width of 76 inches and a length of 80 inches. The California King is 4 inches narrower but 4 inches longer than a standard King, making it ideal for taller individuals or narrow rooms.
Specialty sizes include the Split Queen (30″ x 80″ per half), Split California King (36″ x 84″ per half), RV Queen (60″ x 75″), RV King (72″ x 75″ or 72″ x 80″), and oversized options like the Alaskan King (108″ x 108″). Waterbed-specific sizes such as the Queen Waterbed (58″ x 82″) and King Waterbed (70″ x 82″) are also available. European and UK sizes differ slightly, with the UK Double measuring 55″ x 79″ and the EU King measuring 63″ x 79″. Room size requirements vary: a Queen needs at least 10′ x 10′, a King requires 12′ x 12′, and a Full needs 9.5′ x 10.5′, with at least 2 feet of walking space on each side recommended.
