Is a Twin XL Size Mattress Right For Me?
The twin XL mattress is the same width as its standard twin size counterpart but offers 5 extra inches in length.
The twin XL is an ideal option for taller sleepers such as growing children or college students.
As a general rule of thumb, your bedroom space should be at least eight feet by 10 feet in order to be comfortable.
What Size Is a Twin XL Size Mattress?
The size of a twin XL mattress is 38 x 80 inches. This is opposed to a standard twin size mattress, which measures 38 x 75 inches. Twin XL dimensions are generally the same throughout the mattress industry, so you can expect a twin XL mattress to have the same measurements and fit bedding and bed frames made for a twin XL bed.
The twin XL mattress size is not considered to be an upgrade from the standard twin bed. Instead, it’s a variation of the twin mattress. The XL twin mattress size features five inches of additional length to accommodate taller sleepers, but the mattress is not any wider than a standard twin mattress. Sleepers looking to graduate from a twin mattress to a more spacious bed should upgrade to a full mattress or a queen size mattress.
A full size bed is an upgrade from the twin mattress XL size. Full size beds are recommended for single adult sleepers. While a couple could sleep on a full size bed in a pinch, we recommend couples consider a queen size bed or a larger mattress, like a king or California king mattress.

Frequently asked questions.
Who should sleep on a twin XL mattress?
The twin XL size mattress is made for single sleepers who are more than six feet tall. This includes teens, college students, and adults who want to conserve space.
Many parents buy twin XL mattresses for children too. Twin mattresses are often used as a toddler mattress, and it’s not uncommon for kids to sleep on them until they reach adulthood. If you expect your child to grow taller than six feet, it’s a good idea to invest in a twin XL mattress from the start.
The Purple twin XL mattress is covered by a 10-year warranty, so it’s guaranteed to provide restful sleep and no-pressure relief throughout childhood, adolescence, and beyond.
A few additional reasons to choose an XL twin size mattress include: Affordability: Tall sleepers can save a lot of money by opting for a twin XL. The next bed size for tall sleepers is the queen mattress, which comes with a higher price tag.
Transportability: If you’re moving between houses or apartments a lot (e.g. college students), you’ll probably prefer a twin XL to a full size or queen size bed. A twin XL mattress is much easier to maneuver through doorways.
Doubling Up (Split King): If you want an extra spacious bed or would like to reduce motion transfer, you can put two twin XL mattresses together to form a split king. You can also buy two twin XL mattresses to use with a split king bed frame.

Which is longer: twin XL mattress or full size mattress?
A twin XL mattress is five inches longer than a full size mattress. Compare the twin XL size mattress dimensions and the full size mattress dimensions below:
Twin XL mattress: 38 x 80 inches
Full mattress: 54 x 75 inches
The full mattress is a larger mattress lengthwise, but it is shorter than the twin XL. This can be a bit frustrating to shoppers who think that they are getting a bigger mattress by upgrading to a full size.
Why is mattress sizing so confusing? It’s because the size twin XL mattress wasn’t always a member of the mattress family. It only became popular in the 70s when more adults needed slimmer beds to fit into college dorms and apartments. That’s why the Twin XL is often called the “dorm bed.”
If you’re under six feet tall and want a more spacious mattress, a full mattress will suit you just fine as a single sleeper. But if you’re taller than six feet, you may want to upgrade to a queen mattress to maximize vertical and horizontal sleeping space.
Queen size mattress dimensions measure 60 x 80 inches, so you’ll get the same length as a twin XL and a considerable increase in width as well.

What size of bed frame do I need for twin XL mattress?
You will need a twin XL bed frame for a twin XL mattress. A twin mattress bed frame is not compatible with a twin XL mattress because twin and twin XL are different bed sizes.
If you have a resizable bed frame that features an adjustable length and width, you can use this frame for your twin XL bed.
You can also put two twin XL mattresses together and they will fit on a king size bed frame or a split king bed frame.
There are a number of bed frames you can use to support a twin XL mattress, including:
Box spring
Bunkie board
Bed platform
Slatted base
Adjustable bed frame
Check the mattress warranty that comes with your twin XL mattress for more information about support requirements. The warranty should also include bed frame guidelines so you can get the most supportive frame for your twin XL mattress.
The Purple twin XL mattress is not made for use with a box spring. Box springs tend to lose their support over time and are easily infested by mites and bacteria.
Purple beds are best supported by a Purple Bed Frame™. Purple offers three different bed frames made specifically to complement the look and feel of your Purple Mattress™. They’re guaranteed to protect the warranty and maximize the life of the mattress.
Purple offers a bed frame for all preferences and budgets, including:
Purple Platform Bed: A discreet, affordable, and super supportive bed frame.
Purple Foundation: An upholstered foundation for stylish and durable support.
Purple PowerBase: Purple’s adjustable base, featuring zero-gravity mode.

What size are two twin XL beds together?
When you put two twin XL beds together, they have the same dimensions as a king size mattress (king size bed dimensions are 76 x 80 inches).
Two twin XL mattresses put together are normally referred to as a split king. Split king mattresses are commonly used on split king adjustable bed frames. This allows each partner to adjust their side of the bed to their liking.

Are split king beds comfortable?
Yes! Split king beds are very comfortable. They offer the most spacious sleeping experience for couples of all sizes, and they accommodate adjustable bed frames so sleepers can further customize their comfort.
The combination of a split king mattress and an adjustable base, such as the Purple PowerBase, is considered one of the most luxurious beds you can buy.
When you sleep on a split king Purple PowerBase, you can customize your comfort by adjusting the mattress to your favorite position. You can also choose from Purple’s presets, like zero-gravity mode. This mode suspends your body in a tension-free position that mimics the feel of free-floating (which works best when paired with a Purple mattress).
Not everyone who chooses a split king has an adjustable bed frame. Some opt for a split king to enjoy:
Transportability: If you and your partner move often but still want to enjoy the luxury of a king size mattress, a split king makes it easier to move from place to place.
Versatility: Do you want your guest room to accommodate couples, kids, and family friends? A split king can easily be separated and put back together to make your guests feel comfortable.
Motion Isolation: Light sleepers often choose a split king to minimize the motion transferred across the mattress when a partner changes position or gets into bed. Because the mattresses are separate, very little motion is transferred from one side of the bed to the other.

What is the difference between a twin XL and a twin mattress?
A twin XL mattress and twin mattress have the same width, but the twin XL is five inches longer than the standard twin size. Take a look at the difference between the twin and twin XL mattress size in inches:
Twin mattress: 38 X 75 inches
Twin XL mattress: 38 X 80 inches
Another difference is that twin XL mattresses normally cost a bit more than twin mattresses.
The two bed sizes are very similar and are often mistaken for being the same, but it’s important to recognize the differences. For example, twin and twin XL mattresses require different bedding and bed frame sizes.
Both can be used with a bunk bed frame, but most bunk beds are intended for use with only one mattress size. Mixing up the sizes can be a costly mistake, so make sure you measure your bunk bed frame before purchasing a twin XL mattress.
