Additionally, twin XL beds can also be set up as bunk beds and are great for college dorm rooms, children’s rooms, and other areas that have a limited room size. It is important to know, however, that a twin XL mattress will not fit on a bed frame made for standard mattress sizes since it is a larger mattress overall in length.

Which Size Is Best for You?
If you’re trying to choose between a twin XL vs full size mattress, we’ve outlined the important factors to consider.
At the end of the day, every person has a unique and different sleeping style. Both twin XL mattresses and full beds are popular mattress choices for smaller bedrooms, studio apartments, and other spaces that have a living area that lacks extra space.
We recommend measuring the room before making your decision. Be sure to allot extra space around the mattress so that any sleepers can move and clean around it.
Who is Sleeping in the Bed?
Both twin XL and full mattresses are ideal for single sleepers with the twin XL bed being a better choice in children’s rooms or for teenagers.
Of course, if an individual happens to be taller, then a twin XL mattress might be the better option—and this mattress is also a top pick for college dorms. At the same time, a combination sleeper will likely benefit from the extra space offered by a full bed mattress.
Are you planning to share the bed with a partner, child, or pet? If so, a twin XL is probably too small. A full size mattress may help all of you sleep better due to the additional width. Though keep in mind that some sleepers find a full-size mattress to be too small to share. In this case, it may be best to consider going for a queen or king size mattress to give each person ample room in the bed.
Before shopping, we recommend setting a budget for your mattress purchase. For a twin XL or full-size mattress, expect to spend more money than a regular twin size mattress, especially if you also need to purchase a new bed frame, foundation, or sheets.
Expect a twin XL mattress to be priced between $150-$1,500 and a full size mattress to be priced between $500-$2,000. While these price ranges may be large, they reflect differences in mattress durability, quality, and materials used in its construction.
