Double Bed Size & Dimensions Guide

Double mattress dimensions are typically 53 inches wide by 75 inches long or 135 cm wide by 191 cm long. However, you should check with the manufacturer as double bed dimensions can vary slightly. For more information on mattress sizes, check out our Mattress Size Guide and shop double mattresses.

When comparing a double mattress size to a queen, the difference comes down to dimensions and space. A double mattress, also known as a full size mattress or double bed mattress, typically measures 53 inches wide by 75 inches long (a double bed size in feet is usually 4.4 feet wide by 6.25 feet long), making it ideal for solo sleepers, smaller bedrooms, or anyone looking to save space without sacrificing comfort. A queen mattress, on the other hand, measures 60 inches wide by 80 inches long (or 5 feet wide x 6.67 feet long), offering extra width and length that’s perfect for couples or anyone who prefers more room to stretch out.

A double bed fits comfortably in a room that is at least 9 feet by 9 feet, though 10 by 10 feet or larger gives you more space to move around. With double bed dimensions of 53 inches wide by 75 inches long, aim to leave at least 24 inches of clearance on the sides and foot of the bed for comfortable movement. If your room is smaller, a twin mattress at 38 inches by 75 inches may be a better fit. If you have more space available, consider upgrading to a queen mattress.

A double mattress uses full size or double size bedding, so bed sheets, duvet covers, and mattress protectors labelled as "full" or "double" will fit a standard 53 by 75 inch mattress. In Canada, both terms are used interchangeably so either label works when shopping. Avoid queen size bedding as it will be too wide and long, resulting in excess fabric that bunches or hangs unevenly. Explore Casper bedding designed to fit your double mattress perfectly.
