Some Popular Questions About Mattress Sizes

What mattress size should I get?

Twin mattresses are ideal for smaller individuals, or solo sleepers in small spaces, like a dorm, studio, or loft. Twin XL mattresses are five inches longer and the same width (38”) as a twin mattress, so they are better suited for taller individual sleepers in tighter spaces. A full, also called a double, is ideal for individual sleepers with more space or smaller couples who like to sleep close together. A queen mattress is the most popular mattress size. It gives individual sleepers lots of space and, for most couples, the right balance of space and intimacy. A king-size mattress is perfect for couples who like to spread out in their own space, or those that also sleep with a pet or child. A California king, four inches taller and narrower, suits taller couples who like their own space or those that sleep with a pet or child.

Can two people share a full bed?

Couples commonly share full/double mattresses, but whether or not it’s comfortable depends on the size of the individuals and the amount of space each requires to sleep well.

The term “full” is generally used interchangeably with “double.” The standard size of a twin or double mattress is 54” x 75”.
