Mattress Size Descriptions
Twin Mattress 39" x 75" (Also known as single)This is the most common size found in children's rooms, and is used on daybeds, trundle units and hideaways. The width of a twin mattress (39") is the minimal amount of space needed for a single person to lie comfortably each night.
Twin Extra Long 39" x 80" (Also known as Twin XL)Twin XL, or extra long, is the most common mattress size found in college dorms. The additional 5" in length (compared to a twin sized mattress) accommodates taller sleepers. Twin XL mattresses fit comfortably in smaller rooms because they take up minimal space.
Pros: Standard fare in college dorms. Longer length is good for taller teens and adults.
Cons: Bedding can be more difficult to find.
Full Mattress 54" x 75" (Also known as Double)
Full size beds are 15" wider than Twin beds and 5" shorter than a Queen bed. This size is a good option for a guest room or as a child's step-up mattress.
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.
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 Mattress 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".
Cons: This is a very large mattress that may not fit easily up stairs or into smaller rooms. (Check bendability on king size mattresses.) Taller people may prefer the California King instead with its longer length. All bedding is most expensive in king sizes. Needs 3 standard pillows or 2 king pillows for this width.
California King Mattress 72" x 84" (Also known as Western King)
California King is 12" wider than a Queen bed but adds 4" in length. This may be a better choice for taller adults. This size is sometimes known as the "Western King". 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"
Pros: A California King size mattress is roomy in width for 2 adults. Also, it is the longest standard bed available at about 84", and is ample for most taller people.
Cons: This is a very large mattress that may not fit easily up stairs or into smaller rooms. Sheets are plentiful on the West Coast but may be a bit more difficult to find in other parts of the country, so try looking for them online if you're not on the West Coast. Needs 3 standard pillows or 2 king pillows for this width. All bedding is most expensive in king sizes. You can also buy this size mattress as a Split Cal King. This will allow to deliver Cal King size mattress to the facilities where doors do not allow to bring one piece Cal King mattress in.
