A twin XL is 38 by 80 inches, the standard dorm size and the size two of make a split king, which is how couples put one model on a pair of independently adjustable bases. Labor Day is a good time to buy two: the same discount applies to each half.
Part of the Labor Day mattress sale. Other sizes: king, queen, California king, twin and full. Shop by type: hybrid, memory foam, latex and Tempur-Pedic.
A Twin XL mattress measures 38" × 80" (3 ft 2 in × 6 ft 8 in). Same width as a Twin (38") but 5" longer. The standard college-dorm size, most universities spec Twin XL frames, and the right pick for tall single sleepers (over 5'6") who outgrow standard Twin length.
What pairs with a Twin XL. Two Twin XL mattresses side-by-side equal a Split King (the right adjustable-base setup for couples with very different sleep preferences, see Split King). Twin XL bedding is harder to find at general retailers; we stock fitted sheets and protectors specifically sized for it.
Room sizing. Minimum bedroom is 7 × 10 ft, same width as a Twin so the room footprint barely changes. The 5" of extra length is the only difference. See the full mattress size chart for every size compared, including the dimensions in feet, inches, and centimeters.
Every Twin XL mattress on this page ships with free next-day white-glove delivery across Los Angeles on orders over $499, an optional $100 same-day upgrade if you order by 4 PM, and the 120-night Love Your Bed comfort exchange so you can swap firmness if it isn't right at home.
Same width (38"), different length: Twin is 75" long, Twin XL is 80" long. Twin XL is the standard size for college dorms (most universities require it), and it's the size that two-of pair up to form a Split King for adjustable bases. Twin XL suits adults up to about 6'3"; taller sleepers should consider a Full or Cal King.
No, the 5-inch length difference means a Twin fitted sheet will be too short. Use Twin XL bedding specifically. We carry Twin XL sheets, mattress protectors, and bedding sets at every showroom and online.
Yes, two Twin XL mattresses placed side-by-side equal the exact dimensions of a standard King (76" x 80"). This is the standard configuration for couples using a split adjustable base where each side can elevate independently. If you go this route, look for Twin XLs designed to pair (the seam down the middle should be flush).
Next-day white-glove delivery is free on orders over $499 anywhere in Los Angeles. Need it sooner? Same-day delivery is a flat $100 when you order by 4 PM. We set up the new mattress, haul away your old one, and recycle it, not landfill.
