Mattress Size

Twin 39" x 75" (also known as single)

Most common for children’s rooms, daybeds, trundle units and hideaways.

Twin Extra Long (Twin XL) 39" x 80"

Is generally used in college dorm rooms and is 5" longer than a standard twin. Bedding may be harder to find and available only a limited variety of styles. Approx. width per person: 39"

Pros: Standard fare in college dorms. Longer length is good for taller teens and adults. Easy to make.

Cons: Bedding can be more difficult to find.

Full 54" x 75" (also known as Double)

Full size beds are only 15" wider than Twin beds. This won't leave much elbow room for 2 adults (each will have only 27" of width vs. 39" in a Twin bed). 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"

Pros: Fits into smaller rooms. Sheets are less expensive than queen or king size. Also have the option of using Queen size sheets, which will have more drop length.

Cons: Many people find a Full is too narrow for 2 adults with only 27" in width for each person. And, it may be too short for some.

Queen 60" x 80"

Currently the dominant size bed in America, Queen Beds are 6" wider (and 5" longer) than a Full size bed. These added inches can make all the difference in comfort, but each adult still has 9" less than the width of a standard Twin bed. However, it's a good choice for guest rooms and smaller master bedrooms. Can use standard pillows or the slightly larger queen size pillows. Approx. width per person: 30"

Pros: A better fit for 2 adults. The 80" length comfortably accommodates most adults. Bedding is easy to find.

Cons: At only 30" of wide for each person (only 3" wider than a Full) many people find a Queen is still too narrow for comfortable sleeping for a couple. Note that some bedding is sold as "Full/Queen" and may not perfectly fit either size, so check the measurements before purchasing.

King 76" x 80" (Also known as Eastern King)

King beds are growing in popularity. King is about 16" wider than a Queen bed. Both are about 80" long. The Eastern 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 an Eastern King. 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). An Eastern King bed comes with one mattress and two half-width box springs to be more manageable when moving. Approx. width per person: 38"

Pros: This is the widest standard bed available. Roomy enough for 2 large adults. The 80" length comfortably accommodates most people. Sheets are easy to find and are generally labeled simply "King&q
