Your bed is the foundation of your bedroom, but what size is best? And what is the difference between a King and a California King mattress? Take a look at this primer on bed sizes, and put those questions to rest! Once you’ve found the ideal mattress, you’ll be ready to pick out your dream bedding.
Twin
Standard Twin mattress size: 39”x75”
About Twin beds: This compact mattress is the smallest of the standard mattress sizes, other than crib mattresses. It’s a popular choice for a child or an individual adult with limited bedroom space.
Twin XL
Standard Twin XL mattress size: 39”x80”
About Twin XL beds: A Twin XL mattress is the same width as a standard Twin, but it is 5 inches longer. A Twin XL accommodates a taller youth or adult, and it is commonly found in dorm rooms. A Twin XL is also known as an extended Twin or an extra-long Twin. Look for Twin XL sheets and bedding to accommodate the extra length; pay attention to the mattress depth as well for the best fit.
Full
Standard Full mattress size: 54”x75”
About Full beds: Also known as a Double, a Full mattress is about 15” wider than a standard Twin. It provides a single sleeper with more space to sprawl out from side to side.
Queen
Standard Queen mattress size: 60”x80”
About Queen beds: The most common size for a master bedroom, the Queen mattress is designed for a couple and provides each person with about 30” of personal space.
King
Standard King mattress size: 76”x80”
About King beds: A King mattress is the same length as a Queen mattress, but it is about 16” wider. A King mattress provides a couple with plenty of personal sleeping space—just be sure to check your bedroom dimensions to make sure that it will fit.
California King
Standard California King mattress size: 72”x84”
About California King beds: Despite what you might think, a California King mattress is not wider than a King. A California King is actually 4” narrower and 4” longer than a standard King. If you are very tall, or if your bedroom is especially long, a California King mattress might be best for you. Keep in mind that you’ll want to look for California King sheets and bedding.
