Twin XL Mattresses
Similar to a twin mattress in terms of size, the twin XL mattress also measures 38 inches in width, but features an additional 5 inches of length, making it 80 inches long. This extra length makes twin XL beds a great option for anyone who wants the convenience and practicality of a standard twin size mattress, with a little bit more leg room.
How big is a twin XL mattress?
A Twin XL mattress is 38 inches wide by 80 inches long. You can combine two twin XL mattresses on a standard king size bed frame to create a king size bed.
Who Should Sleep On A Twin XL Bed?
The compact size is great for growing kids or single individuals who need the 80 inches of bed length.
Because of their narrow width, twin XL mattresses are best for smaller rooms; especially kids rooms or college dorms.
The second smallest standard mattress size, use the twin XL for high quality comfort at a great value.
