how bigis a twin xl

A Twin XL mattress is typically about 38 inches wide and 80 inches long (roughly 96.5 cm by 203 cm).

Quick Scoop

• Standard Twin XL size: about 38" wide x 80" long.

• That’s the same width as a regular twin, but 5" longer for taller sleepers.

• In many dorms and college housing, Twin XL is the default bed size.

• Two Twin XL mattresses placed side by side equal the size of a standard king (76" x 80").

How it compares

• Twin: about 38" x 75" (shorter by 5").

• Queen: about 60" x 80" (same length, much wider).

• King: 76" x 80" (exactly two Twin XLs side by side).

TL;DR: If you’re tall or dealing with a dorm/compact room, a Twin XL gives you extra legroom without taking up as much floor space as a full or queen.
