How long is a twin XL bed? An extra long twin mattress is only five inches longer than a standard twin with total dimensions of 38" in width x 80" in length. This makes it a great option for taller single sleepers.

Twin vs. Twin XL

A twin mattress is a great option for children and adults who don't have a sleeping partner. However, for some people, a twin extra long mattress may be more ideal.

The only difference between the two options is length. But how long is an XL twin bed? The answer is only about five inches longer than a regular twin.

Which Size is Best for You?

Before choosing between twin vs twin extra long, here are some important factors to consider:

Cost & Availability – An extra long twin mattress will usually cost between $50 and $150 more than a standard twin. However, extra accessories, like an extra long twin comforter, may cost more and be harder to find.

Height & Sleep Position – For sleepers over six feet in height, an extra long twin air mattress may be preferable. A standard twin is just over six feet, but you have to bear in mind your pillow takes up additional space.

Growing Children – Mattresses should last around 10 years, but kids grow quickly (especially starting in 5th grade). Parents with growing children may want to get a Twin XL and make sure they don't have to buy another mattress any time soon.

Bedroom Dimensions – Both mattresses should be able to fit in any standard bedroom. However, if your bedroom is more of a closet, then a twin XL may not be a good choice.

Can you use a twin bed frame and bedding for a twin XL mattress?

If you want to upgrade your twin mattress to a twin XL size, you'll also need a twin xl bed frame. The extra 5 inches may not seem like much, but it's enough that you'll need new accessories.

Twin XL accessories have been difficult to find in the past, but many companies are seeing the rise in demand for this particular size of mattress. New products (sheets, comforters, frames) are coming out all the time. Especially if you have junior high-age kids who are growing and need more room, consider upgrading their bed for that bit of extra space that will be so important for their development.
