Full Bed vs. Double Bed: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 22, 2023
A full bed and a double bed are terms that refer to the same bed size, typically measuring 54" x 75".

Key Differences

A full bed is commonly understood to be a mattress that measures approximately 54 inches in width and 75 inches in length. A double bed is essentially the same size as a full bed, and the terms are often used interchangeably.
Historically, the term "double bed" was more prevalent, implying that it was double the width of a twin bed. Today, the term "full bed" is more frequently used, though it signifies the same dimensions as the double bed.
When shopping for bed linens or frames, you might find both terms used by manufacturers and retailers. Whether labeled as a full bed or a double bed, they will fit the same sized mattress and offer similar sleeping space.
For single sleepers, a full bed or double bed offers ample space. However, for couples, it might be a bit cozy since each person gets only 27 inches of space, which is less than a twin bed per person.
Both the full bed and the double bed are smaller than a queen-size bed, which provides more width for sleepers. Regardless of the terminology, the space offered by a full or double bed remains the same.
