Twin 39″ x 75″
The smallest one. Perfect choice for kids and small apartments. If you are an adult and want to save some space it can be good for you. Popular in dorms. Not appropriate for taller people.
Twin XL 39″ x 80″
Still one of the smallest mattresses but has a bigger length. Much better for taller people. It’s good for an adult or teenager. Often used in dormitories.
Full 54″ x 75″
A good option for a single person or a couple who don’t have enough space. It’s the smallest size that is appropriate for a couple. It can also be used for a single person if you are rolling over in your sleep, afraid of falling out of your bed or just enjoy the extra comfort, it’s for you.
Can be used for two adults in case you don’t have much space or don’t use it too often (mattress for guests).
Full XL 54″ x 80″
Same as full but made for taller people. Requires more space
Queen 60″ x 80″
Good for two people. One of the preferable sizes. Not using too much space.
King 76″ x 80″
It’s wider than “Queen”. If you have more space in your room… why not? Sometimes our kids want to sleep with us…
California King 72″ x 84″
It’s not that wide but longer. Nice for taller people and those who have pets sleeping near their legs
