Let’s talk a little more mattress sizes. You may not realize it, but the size of your mattress does affect your sleep quality. It can even be one of the more important aspects of a quality nights rest. Having plenty of room for each person means having a little more room than the bodies sleeping on the mattress. If you are too cramped it will derail your night, so make sure you have a sleep surface that is longer and wider than you and your sleep partner with enough room to move around a little, too. Anything that interrupts your night’s sleep is detrimental because it forces you to restart your current sleep stage. If your sleep cycles are constantly interrupted and restarted, this means you’re not obtaining your deepest level of sleep, Stage 4, R.E.M. Sleep.

Twin. A standard twin mattress measures 39″ X 75″. This is the most commonly used size for children’s sleep products like bunk beds. Some single adults prefer a twin size mattress, too. Twin mattresses are often referred to as singles and are the standard size for daybeds.

Twin- XL. A standard twin-xl mattress measures 39″ X 80″. XL is an abbreviation for extra-long and provides an extra 5″ in length to accommodate taller people. These are made to the same length as a queen or king mattress. And are typically used for “twin sized” adjustable mattresses and power bases.

Full. A standard full mattress measures 54″ X 75″. Standard became their name when they were “the standard” for bedrooms of the past, which were much smaller in size. Now they are generally considered too small for two adults to sleep on since they provide less space than two twins. They are sometimes referred to as double or standard beds.

Full XL. A Full XL mattress, measures 54″ X 80″. While not the most popular size, it is used for Adjustable Sleep Systems to maintain the width of the Full but allowing the extra length that would be otherwise lost, when the head and feet portion are raised.

Queen. A standard queen mattress measures 60″ X 80″. This is the new norm of today, providing a good amount of space for two adults to sleep. This is the most popular size sold today.

King. A standard king mattress measures 76″ X 80″. When you have a large enough bedroom, a king size mattress will provide a luxurious amount of space for two adults and the family tag-alongs. A typical king is properly referred to as an Eastern King.

California  King. A standard Californian king mattress measures 72″ X 84″. This mattress offers all the advantages of a king, but is made extra-long for taller people. Sometimes, California Kings take a little longer to arrive, and not all mattress manufacturers offer each model in this size. While many believe California King is the largest size available, it actually offers 32 square inches less of surface area, than the Eastern King.
