What are the dimensions of a full-size bed?

A full-size bed measures 54 inches wide and 75 inches long. The full-size bed, also called a double or standard bed, was a popular choice in the 1960s when homes had smaller bedrooms.

Many couples find that a full-size bed is too small for both people to sleep comfortably. A full-size mattress only allows each person about 27 inches of sleeping space. Therefore, most couples prefer to purchase a queen-size bed, which is 60 inches wide and 80 inches long, or a king-size bed, which is 76 inches wide and 80 inches long. Most full-size beds are purchased for children's bedrooms or guest bedrooms.
