Various Mattress Sizes And The Room Sizes You Should Have Them

Most of us can’t decide on which size of mattress to choose and which one will suit us. You may be choosing the right material or may like a bigger mattress but do remember the size of your room. It is most important to know which mattress will fit in which room. After deciding on these aspects you can buy the one that suits you the best.


Here are a few things you have to check before buying a mattress:

1) Crib:

Conventional crib mattresses are made specifically for newborns and cribs. The ideal size of a full-size crib mattress should be 28 5/8″ wide by 52 5/8″ long, thickness should not be more than 6″. Sizes will vary, but it’s fine as long as they’re close to those measurements and suit your crib without being too little or too thick. These mattress sizes will be well fitted in most toddler beds once your infant outgrows the crib.

The ideal room size for the crib is 7′ by 10′, which is the same as the size of a twin bed.

2) Twin:

Twin beds are most typically used for bunk beds. They can also be found in different combinations such as a twin over full or twin over queen if there are numerous sleepers on the bottom.

This one may be a perfect solution for standard height couples who want to share a room but not a bed. It’s perfect for couples that require their separate sleeping quarters; it improves their sleep quality, eliminates movement disturbances, and makes some couples simply happy.

This bed requires a room that is 7′ x 10′ or 10′ x 10′ for two twin beds in the same room.

3) Short twin:

Short twins are often used in motor homes. Because motorhomes and campers are much smaller than your home, everything, including the beds, will be smaller. The ideal measurement of short twins is 34″ × 75″. You also can choose according to your room size.

This bed should be placed in a room that is 7′ x 10′ in size.

4) Twin XL:

Twin XL is specially designed for extra-large rooms. If you are taller than a normal person then this is the best option for you. These are 39 x 80 inches in size, which gives you an extra 6 inches in length. It also provides space for your pet at the foot of the bed.

The ideal room size for this one is 7′ × 10′

5) Full:

Full-size mattresses are 54 x 74 inches, which is 16 inches wider than a twin. These are often used in hotels. Two tiny people can easily sleep on it, yet if you move about a lot while sleeping, your companion may not enjoy the size of the bed. These are perfect for older kids who have outgrown their twin beds. Parents can also easily cuddle up next to their children when tucking them in for the night because of the size. A futon folds down into a bed, and is also available in this size.

The room size should be 10′ × 12′ to place it.

6) Full XL:

These come in 54″ × 80″ sizes. These are specially designed for taller individuals. Couples also can sleep on it. Each one has approximately 27 inches of sleeping space.

Room size should be 10′ × 12′ – 10′ × 16′.
