Full mattress dimensions and shopping guide
A Full, also called a Double, is approximately 54 inches wide and 75 inches long. It gives one sleeper about 16 inches more width than a Twin while keeping the same nominal length. It can suit a guest room or a single sleeper who wants more space to turn.
Full vs Queen: choose width and length together
A Queen is about six inches wider and five inches longer than a Full. Two people sharing a Full have about 27 inches of nominal width each, so compare a Queen or King if personal space is a priority. Measure the complete bed frame and walking paths before selecting the larger size.
