100 Percent Cotton Twin XL Sheets

100 Percent Cotton Twin XL Sheets — The Dorm Bed Deserves Real Cotton

Twin XL is the standard size for many dorm beds across the country, and it is often the first bed a young adult sleeps in away from home. A dorm bed gets slept in hard and washed in shared machines, so the cotton you choose matters. 100% cotton twin XL sheets soften with every wash. For a full breakdown of what twin XL sheets actually are and how they differ from standard twin, read our guide on what are twin XL sheets.

Twin XL vs. Twin: The Five Inches That Matter in 100 Cotton Twin XL Sheets

A standard twin fitted sheet is 39" x 75". A twin XL fitted sheet is 39" x 80": the same width, five inches longer. A standard twin fitted sheet will not fit a twin XL mattress. For exact pocket and sheet dimensions before you buy, read our guide on twin XL fitted sheet dimensions.
