Twin XL Size Mattresses

Shop Twin XL Mattresses

Twin XL mattresses measure 38-inches by 80-inches. Twin XL size mattresses are also known as twin long and are the same width as twin size but are 5-inches longer.

Two Twin XL mattresses side-by-side makeup a split king size. Twin XL is a great bed size for dorm rooms, kids rooms, guest bedrooms and for taller sleepers and growing teens.

Narrower than a full size by 16-inches, but measuring 5-inches longer than a full, the Twin XL size is a great value for the price. Couples will not be comfortable on this size, as it does not provide enough space for two people.
