Mattress Sizes and Dimensions
TWIN – 39″ x 75″
Twin size is generally made to accommodate one child or one adult sleeper. On occasion when you need to lay with your child it should accommodate, but will be a bit crowded. If you are a taller adult you may want to consider a twin-XL which will give you added length. (see below). Twin (also referred to as ‘single’) is great for smaller guest spaces, bunkbeds, and daybeds.
TWIN XL – 39″ x 80″
Twin-XL size (Extra-Long) is 5 inches in length longer than the standard twin. This size is great for taller youth or adults. Twin-XL is the same length as a queen or king, In fact two of them side by side equals a king.
FULL – 54″ x 75″
Full size or also known as a ‘double/standard’ was commonly used for two adults 30 – 40 years ago when the homes and bedrooms were built much smaller. Now it is usually purchased for single person use and sometimes smaller guest rooms. It is a tight fit for two adults and the same length as a twin. Two adults sleeping on a full size is equivalent to each person sleeping on a crib mattress (27 inches of sleep space). Most people with a sleeping partner opt for the queen size. Full can sometimes be special ordered in extra long.
QUEEN – 60″ x 80″
Queen size is the most popular size sold. Ideal for two adults who don’t want a king size in order to save living space. Also great for those who just like to spread out.
KING – 76″ x 80″
King size is the same length as a queen but much wider (16 inches). If you have the space it offers the most room for couples. King size beds are also great if you have kids or pets who like to share your bed.
CALIFORNIA KING – 72″ x 84″
California King size mattresses are 12″ wider than a Queen bed but they add 4″ in length. This may be a better choice for taller adults. The approximate California king width measurement per person is 36″.
