What is a Full-Size Mattress?

Full mattresses are 75 inches long and 54 inches wide and are perfect for single sleepers who love to have a little extra space. Full-size mattresses, also known as a double beds, are ideal for guest rooms; the extra inches in width give you some extra space and will not cost you a fortune. They can also be used by couples who like to cuddle and sleep. However, it is not the best option for couples out there. 

Pros

  • Spacious enough for a single person
  • The extra space can easily accommodate a small pet
  • Multiple options for accessories and bedding 
  • Cheapest mattress size for adult single sleepers 

Cons

  • It cannot accommodate a couple comfortably
  • Shorter than a twin XL, so not suitable for tall individuals 
  • It cannot fit in a narrow bedroom
  • More expensive than a twin XL mattress

What is a Twin XL Mattress?

A twin XL is 80 inches long and 38 inches wide and offers additional legroom compared to a standard twin, making it suitable for single sleepers who are tall and do not need extra width space.

Pros

  • Its longer than a full mattress making it comfortable for taller people
  • Cheaper than a full-size mattress
  • It can easily fit in narrow bedrooms such as dorm rooms
  • Cost-effective, especially for children in their growing years.

Cons

  • Fewer accessories compared to a twin or full mattress
  • A twin XL occupies more space and costs more than a twin mattress 

Twin XL vs Full Mattress: Things to Consider Before Buying

Who is Using the Mattress 

Both twin XL and full mattresses are great options for a single person, but not ideal choice for couples. If you have a pet, you might want extra space on the bed which is possible with full size mattresses but not with twin XL beds. 

Size of the Bed 

The bed size required for a twin XL mattress is 38.5” x 75.5,” and for a full mattress, 54.5” x 75.5”. Do check the design, the bed frame, and the brand of the bed before you chose the size. 

Extra Accessories 

The accessories for a full mattress are more commonly available than a twin XL. A twin XL can be accessorized with a single pillow while a full bed can accommodate two pillows or more if you accessorize the same. 

Budget 

While a full mattress is more expensive than a twin XL, its accessories also add to the cost. Twin XL costs around $500, whereas a full-size mattress may cost you an additional $200 compared to the price of a twin XL.

Height of the Person

Another factor while selecting a mattress is the height of the sleeper. If the person is tall, it is only wise to buy a twin XL for the extra inches in length instead of a full mattress. 

Bed Room Size

For a twin XL, the ideal bedroom size is 9 feet by 9 feet, while for a full mattress, the perfect bedroom size is 9 feet by 9.6 feet. This difference restricts the twin XL to narrow bedrooms. 

When it comes to the difference between full and twin XL in terms of bedroom size, the only difference is in the width.
