Mattress Size Chart
TWIN - 39" X 74"
A twin size mattress is the smallest mattress available and is best suited for one child or one adult. The dimensions of a twin size mattress are approximately 39 inches wide by 74 inches long.
FULL - 54" X 74"
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 5’5”. Full beds are 54 inches wide by 74 inches tall. A full size mattress is a great choice for growing children, plus the added space allows for parents to lie down while tucking their kids in for the night.
QUEEN - 60" X 80"
Queen size mattresses provide more width than a full size mattress, which adds additional comfort for two sleepers. Queen mattresses are the most popular mattress size today. With the dimensions of 60 inches wide by 80 inches long, the queen size mattress is a good choice guest rooms or couples that like to sleep closer together.
KING - 76" X 80"
King size beds are best for couples that want the maximum amount of sleeping space. King size mattress dimensions are approximately 76 inches wide by 80 inches long, making a king mattress almost the same size as two twin XL beds. This bed size is also preferable if you have children, dogs or cats that will be sharing your bed. Since king mattresses are much longer and wider, the box springs are split, making it easier to navigate around stairs and tight corners.
Fun Fact: If you purchase a “split king” bed with an adjustable base, you are actually ordering two twin XL beds.
