Mattresses come in a variety of sizes to meet every need. Here is a review of each.
A twin is 39" x 75" and is most commonly used for a child's bed or occasionally in a guest room.
- Twin Extra Long (Twin XL)
A twin extra long is 39" x 80", 5" longer than a standard twin. These are often used in college dorms to accommodate any sized student. Bedding may be harder to find and available only a limited variety of styles.
Full size beds are built for two people, but they are only a little bit wider than a twin. This won't leave much elbow room for 2 adults. Also, a Full bed is only 75" long which may be too short for some adults. But, this size is a good option for a guest room or as a child's step-up mattress. Approx. width per person: 27"
- Full Extra Long (Full XL)
This is the same width as a full BUT has the length of a queen and king!! This is a much better option for bedroom space without giving up the queen length. 54"x80"
Again ... bedding may be a bit more challenging to find!
A queen mattress is 60" x 80" and the primary bed size in America, queen beds are 6" wider (and 5" longer) than a full size bed, making them much more comfortable for two adults, though it is less space for each adult than in a twin bed. However, it's a good choice for guest rooms and smaller master bedrooms. Standard pillows or slightly larger queen size pillows can be used. Approx. width per person: 30"
King beds are 76" x 80" and growing in popularity. A king is about 16" wider than a queen bed. Both are about 80" long. The king is the only bed to give each person the same width as a twin bed. In fact you can push 2 extra-long twin beds together to be the same size as a king bed. This is a good way to have a versatile guest room (use 2 twins separately or push together to make a king bed for couples). A king bed comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 38"
- California King (Western King)
A california king is 72" x 84" and is 12" wider than a queen bed as well as 4" longer. This is often a better option for taller adults. Bedding may be labeled either "California King" or "Western King". A california king bed set comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 36"
There are other, specialized sizes available as well. such as full extra long and custom sized.
