The main difference between a twin vs. twin XL mattress is in their bed dimensions. The twin-size mattress measures 38 inches in width and 75 inches in length, perfect for short sleepers. It's also an excellent space-saving option that allows you to move around and add more furniture to your room.

On the other hand, the extra five inches of a twin XL can make a world difference for taller sleepers. The twin XL has a dimension of 38 inches in width and 80 inches in length. It can accommodate taller heights and provides extra space to move around during sleep. Despite being a bigger option, a twin XL is still ideal for smaller rooms because it has the same width as a twin.


Finding the right mattress is key to restorative sleep. A twin bed is ideal for kids ages 5 to 12 and adults under 6 feet. However, if your height is over 6 feet, you may need to opt for a twin XL bed instead. The twin XL mattress is long enough that your feet won't hang off the mattress.

Keep in mind that pillows also play a significant role in a comfortable sleep, and they take up quite a bit of space. If you are the type to sleep with plenty of pillows, a twin XL could be the perfect option.

On the other hand, the twin XL bed is five inches larger than the standard twin, so it can accommodate tall sleepers. However, this may take up too much room to allow for bigger furniture or appliances. 

Take note that you need adequate space to move around freely. So, before you decide which size is the best for your needs, make sure to measure your bedroom.
