38 inches by 74.5 inches
Twin beds are the most common mattress size for single sleepers. Great for making the most of a small space. Twin-size mattresses are also used in bunk beds.
38 inches by 79.5 inches
The same length as a King and Queen-sized mattress, the Twin XL is a great choice when taller individuals will use the mattress. A Twin XL is the same width as a standard twin mattress but features a few extra inches of length. Two Twin XLs side-by-side equals one king-sized mattress.
53 inches by 74.5 inches
Often called a double mattress. While used in the past by couples, it is more commonly used today by a single adult. This size provides enough space for an individual to spread out without compromising floor space. Since a full mattress can accommodate 1-2 people, it's a great option for guest bedrooms.
60 inches by 79.5 inches
The most commonly purchased and popular mattress size. A perfect choice for couples or one person who likes to stretch out. If your master bedroom is on the smaller side, a standard queen is recommended.
76 inches by 79.5 inches
The same length as a Queen mattress but wider. A king mattress gives two adult sleepers plenty of room to spread out comfortably. This is the perfect option for couples co-sleeping with children or pets because of the generous width. Our customers tell us the extra space helps them sleep better. King size mattresses are rapidly overtaking Queen size mattresses in popularity.
72 inches by 83.5 inches
One of the longest beds available. A California King is 4 inches longer but 4 inches narrower than a standard king mattress. Best for very tall individuals, or when you want to maximize sleeping space, but the bedroom is too narrow for the width of a King.
Queens tend to be the perfect choice for couples. While full or double mattresses are large enough for two individuals, it might feel a little crowded if you tend to spread out or need personal space. It all depends on your personal preference and what kind of sleepers you both are.
While a King and California King offer plenty of space for two and possibly even three people, these sizes might seem small compared to the Alaskan King. An Alaskan King mattress is 9 feet by 9 feet. To put that into perspective, a standard California King is about 6 feet by 7 feet.
Taller people and individuals 6 feet tall and above prefer King and California King mattresses. The King is an excellent choice for tall couples as it allows the perfect combination of width and length. The Cal King offers a bit more length than the King but is a few inches narrower. Beyond the common sizes, extreme options such as the Alaskan King give you plenty of space, regardless of your height.
