As the table shows, the main difference between twin and twin XL sizes is the length. 

A twin XL bed is 80 inches in length, 5 inches longer than the twin. This means that the twin XL, in the same length as a queen mattress, is usually ideal for taller people. It can provide them with additional space, so that they can keep their legs straight whenever necessary. In other words, a twin bed best fits children and single adults that are lower than 6 feet. 

Another essential factor that makes a twin mattress different from a twin XL is the cost. The twin can help you save the most space at the lowest price, and the wide availability of this size also save a lot on bedding essentials and bed frames,etc. All while, a twin XL mattress commonly costs higher than a twin bed, as well as its bedding accessories.

The following is a simple summary on the pros and cons of a twin or twin XL mattress.

Considerations for Choose the Best Mattress Size

Budget and availability 

Though these two sizes are at an affordable price tag, twin mattresses generally cost less than twin XL. The accessories for a twin XL mattress is not as widely available as a twin, and they tend be more expensive. If you’re on a tight budget, we could recommend you to choose a twin size mattress.

Height and comfort 

Due the extra 5’’ on length, a twin XL bed offers more space for taller sleepers to place their legs comfortably. With this consideration, a twin XL is better for adults taller than 6 feet or growing teenagers, seeing that the longevity of a mattress is typically more than 7 years. And a twin is best for children, teenagers or adults who are less than 6 feet.

Bedroom dimensions

The recommended minimum room size for twin mattress is 7 feet by 10 feet, and the twin XL, 8 feet by 10 feet. Both of them are suitable for most rooms but a twin XL might make your room look more compact with its longer length.

Sleep positions

Both twin and twin XL size mattresses are narrow and that's why they are best for kids, teens and petite sleepers. If you're a combination sleeper who like to sprawl on the bed, a full size mattress might ensure you're comfortable and supported.
