The only difference between the two of them is their length.  But these five inches of difference in length can make a big difference depending on who has to sleep on it. Whether this mattress is for a child or your guests, can be an important point to consider. Let us look at the main difference between twin and twin XL mattresses for making an informed choice.

One of the first things that we consider while choosing a bed is its size. A regular twin size mattress measures 38 x 75 inches. This mattress is what we usually buy after a child outgrows his crib. Ideal for a child’s room, this mattress can last till your child reaches high school.

A twin XL mattress measures 38 x 80 inches and is ideally suited for guest rooms. We can also use it for college dorm rooms.

While the width of the two mattresses is the same, twin XL dimensions has extra length, which is useful as it can accommodate taller people as well.


The twin mattress is slightly cheaper than the twin XL mattress. The same goes for all the other accessories like the bed frame, spring and other parts. So, if budget is a consideration, you can opt for a twin mattress.

Twin XL has its advantages in spite of being a bit more expensive. It is better to opt for a twin XL if you feel your child will outgrow a twin mattress very soon. This way you avoid the expenditure of upgrading to a bigger bed.

Comfort and length

When it comes to comfort twin and twin XL mattresses are quite similar. They are both 38 inches in width which gives ample space to the person who is sleeping on it. The twin bed is perfect for a small child as it gives him ample space to relax comfortably on his bed and enough space around it as well.

The twin XL mattress suits an older child or an adult perfectly as it gives extra 5 inches in length for him to be able to sleep without feeling cramped or having his feet hanging in the air.

Room size

The correct room size for a twin bed is 7 x 10 feet. If you want to fit two of these in the room, the room size should be at least 10 x 10 feet. You must take into consideration that there should be at least two feet of space around the bed for your child to be able to move around comfortably.

Children also need space to play and to put other pieces of furniture in their room, so make allowance for that as well.

A twin XL mattress takes a little more space in the room as compared to a twin mattress. So, opt for this one only if you have the room for the extra length of this bed.


Accessories like sheets, pillow covers and comforters for both these beds are readily available, and there is not much of a difference when it comes to prices.

Things to consider

  • Measure the dimension of your room before you go shopping for the new mattress. We often overestimate the size of the room and can end up buying the wrong size of the mattress.
  • Shop for your bed when the ‘back to school’ sales are on. You will be able to get the best deals for your twin or twin XL bed around this time.
  • Labor Day weekend is an excellent opportunity to shop for your new mattress.

Final verdict on twin vs twin XL

The first thing to consider while choosing between twin and twin XL mattresses is who will be sleeping on it. If it is for a small child, a twin mattress is your best bet. If it’s for an older child or a guest bedroom, opt for twin XL mattress. The additional length is worth the space lost in the room.
