Twin XL FAQs

What size is a Twin XL mattress?
A twin XL mattress measures approximately 38" wide by 79.5" long, which is roughly 3,040 square inches or 21.1 square feet of space.
What is the difference between a Twin and a Twin XL?
A standard Twin is 38 x 74.5 inches. A Twin XL is 38 x 79.5 inches, so it has the same width and 5 more inches of length.
Can a Twin XL go on a Twin bed frame?
No. The extra length means it will hang over a standard twin frame. Buy a Twin XL frame, or check that your existing frame lists Twin XL as a supported size.
Is a Twin XL a good size for adults?
It is the better choice over a standard Twin for adults, since an 79.5-inch length matches a Queen. Width is still 38 inches, so it suits one sleeper.
Is a Twin XL the same size as a Full bed?

No. A Twin XL is longer by 5 inches and a Full is 15 inches wider.

Full size dimensions: 53 inches wide by 74.5 inches long.

Do two Twin XL mattresses make a king?
Yes. Two side by side measure 76 x 79.5 inches, the same as a King.
What is a Split King?
A Split King is two Twin XL mattresses on one frame. It has the same footprint as a standard King, and each person can pick their own firmness or adjust their side separately.
Do dorm rooms use Twin XL?
Many do, but not all. Check your school's housing guide for the mattress size before you buy.
