Twin XL Bed Sheets

Twin XL bed sheets cut to the full 38 × 80 in. dorm-length mattress — five inches longer than a standard twin, and the exact size university residence halls, adjustable king halves and homecare beds all use. Our twin XL bed sheets are 100% combed long-staple cotton in a 300 thread count percale, with a 16 in. deep pocket, full-perimeter elastic and one 20 × 30 in. standard pillowcase in the 3-piece set.

Why twin XL bed sheets exist as a separate size

Move-in day, and the sheets are five inches short. It happens every August, because a twin XL looks like a twin until the fitted sheet is on it — 38 inches wide either way, but 80 long instead of 75. Nearly every university residence mattress is twin XL, and so is each half of an adjustable king base, and neither will take a standard twin sheet. Twin XL bed sheets exist because those five extra inches change the buy completely.

Twin XL bed sheets — designed for shared laundry

Fabric priorities for a bed that gets washed in a shared laundry on whatever cycle is free: fast drying and resistance to creasing rather than maximum thread count. 300 TC combed long-staple cotton hits that sweet spot — substantial enough to last a full academic year, light enough to dry between class changes.

Twin XL bed sheets size guide

The 16 in. pocket is worth checking against dorm-topper depth — many university residence beds carry a 2–4 in. memory-foam topper on the mattress, and a shallow pocket will not clear the combined depth. Measure before ordering.

Where twin XL bed sheets are used

• University residence halls — nearly every dorm mattress is twin XL
• Adjustable king bases — each half is a twin XL cut
• Guest daybeds and bunk tops
• Homecare and hospital beds
• Bunk beds where the mattress is longer than standard twin

Twin XL vs Twin — a five-inch mistake

Twin and twin XL share a 38 in. width but differ by five inches in length. A standard twin bed sheet on a twin XL mattress rides up and leaves the mattress exposed at the foot; a twin XL sheet on a twin bunches at the corners. Always confirm the mattress length before ordering.

How to care for your twin XL bed sheets

• Machine wash warm (or hot for shared laundry loads)
• Tumble dry low
• Skip fabric softener — reduces breathability
• Iron warm only if desired; percale takes a press well
• Buy two sets: laundry day and bed-making day rarely coincide

Frequently asked questions

What size is a twin XL bed sheet?

A twin XL bed sheet fits a 38 × 80 in. mattress — five inches longer than a standard twin. The flat sheet is 66 × 102 in.; one standard pillowcase is included.

Are dorm bed sheets the same as twin XL?

Yes — nearly every university residence hall mattress is 38 × 80 in. twin XL. If your dorm asks for “extra-long twin” or “dorm sheets,” this is the size.

Do twin XL bed sheets fit an adjustable king base?

They fit each half. A full adjustable king needs two twin XL fitted sheets (or our Split King bed sheets set which contains both).

How deep are twin XL fitted sheet pockets?

16 in. on our set. Check the dorm mattress plus any topper depth before ordering — if the total exceeds 16 in., choose the deep-pocket option.
