Twin for bunks and kids, twin XL for the dorm
A twin is 38 by 75 inches and a twin XL is 38 by 80. Most college dorm beds are twin XL, so a twin cover will not close over a dorm mattress.
Bunks and daybeds take thinner mattresses, often 6 to 8 inches. Several covers here are cut for that depth on purpose: a loose cover on a thin mattress bunches under the sheet and wears at the folds.

| Linenspa Zippered Waterproof Mattress Encasement | 12" | $19.10 |
| SureGuard Mattress Encasement | 6-8", 9-12", 13-16", 17-20" | $47.97 |

Questions
Questions about twin and twin XL encasements
What does a twin bed bug encasement cost at Bed Bug Blocker?
From $18.99 for the Utopia Bedding Zippered Mattress Encasement at the twin size, at our latest update, and up to $91.99 across the 21 twin covers on this page.
Will a twin cover fit your pillow-top mattress?
Measure your twin mattress from the bottom seam to the top of the pillow-top. The deepest twin cover here is the Four Seasons Essentials Six-Sided Zippered Mattress Encasement, made for 9-24" deep mattresses.
Do you need a twin box spring cover too?
If your twin bed stands on a box spring, yes: it has more places to hide than the mattress. A twin platform bed or slatted frame needs only the mattress cover.
