Twin Mattress. A twin mattress is the smallest possible mattress size, other than a crib-sized mattress. Twin mattress dimensions are approximately 38 inches wide by 75 inches long. Both twin and full sizes are approximately 75 inches long, which may be too short for some adults, especially men.
The full size mattress, also known as a double mattress, is approximately 16 inches wider than a twin mattress, but does not provide enough added room for two people to sleep comfortably. It may be too short for adults taller than 5â5â. Full beds are 54 inches wide by 74 inches tall.
