What size are dorm beds?

The majority of dorm rooms are equipped with twin XL beds and mattresses (39 inches wide and 80 inches long), meaning you'll need to find twin XL bedding and accessories. Luckily, Twin XL is a standard bed size so you won't have to look too hard for suitable mattresses, toppers, and other bedding. 

Our guide to this year's best mattresses for college students features twin XL beds for under $500, and you can find even cheaper beds in this year's best cheap mattress guide.
