A twin mattress is one of the most versatile mattress sizes for single sleepers. It’s the perfect mattress size for growing kids, or a snug option for an apartment or guest room.
Are you currently weighing up different mattress size options? This comprehensive guide lays down everything you need to know about the trusty twin bed. From twin mattress dimensions to the key features to look out for when selecting a twin size bed for you or a loved one, you’ll find all the information you need.
Twin Size Mattress Variations
There are three primary types of twin bed mattress sizes. The standard twin mattress size is the most popular.
You can also buy a twin XL mattress size - it’s a common choice for taller sleepers who don’t want their feet hanging off the end of the bed.
The last type of twin mattress variation is a split-king. When you combine two twin XL mattresses, you get a split-king mattress. It’s a favored option for couples who sleep on an adjustable base.
You’ll find a complete breakdown of twin size mattress dimensions for these variations below.
Standard Twin Size Mattress
The size of a twin mattress is 38 inches wide and 75 inches long.
Standard twin size beds are the most common choice for children transitioning from crib to big bed. If you're looking for the best kids mattress, a twin memory foam mattress is a great choice for support and durability.
Twin XL Size Mattress
The twin XL mattress size is 38 inches wide and 80 inches long.
A twin XL mattress is 5 inches longer than a standard twin size mattress. It's the perfect choice for tall teens or adults who don’t toss and turn a lot but need the extra legroom. If you are upgrading your child’s mattress, consider buying a twin XL or full size mattress. Doing so will ensure they don’t outgrow their bed if they shoot up in height.
Split-King Mattress (2 Twin XL’s)
The size of a split-king mattress is 78 inches wide and 80 inches long. This is the combined dimensions of two twin XL mattresses placed side by side.
Split-king mattresses have gained huge popularity with the rise of trending adjustable bases. When an adjustable base is topped with two twin XL mattresses, each side of the bed can be independently controlled with wireless remotes. Separate controls give each side of the bed a unique comfort experience. It’s like having two beds in one!
Types Of Twin Mattresses
You can find a twin mattress in a variety of mattress types. This includes latex mattresses, spring mattresses, memory foam mattresses, and even hybrid mattresses.
A twin memory foam mattress is the best choice for a sleep experience that is both cool and comfortable. Memory foam is ultra-supportive and can help relieve stress from pressure points and support the spine throughout the night.
For additional contouring and more balance, a twin hybrid mattress will deliver on comfort and support. Hybrid mattresses are known to combine the stability and durability of springs with the cozy comfort of luxurious memory foam for a supportive sleep like no other.

When To Use A Twin Size Mattress
There are endless ways to sleep comfy on a twin size mattress. Unless you have a split-king, a twin size mattress is roomy enough for just one sleeper.
Two people on a twin mattress means just 19.6 inches of space each - that’s a tight fit! We’ve listed all the most popular ways to use a twin mattress below.
Kids bedrooms
The biggest fans of twin mattresses are kids. When transitioning from the crib to normal bed, twin size mattresses are a natural choice. Twin beds are also perfect for bunk beds if you have kids who share a bedroom.
Teen Bedrooms
A twin bed mattress in a teen bedroom leaves plenty of floor space for a study desk or an area for your teen to relax. Consider a twin XL when upgrading so you have peace of mind that the bed will be big enough to cater for sudden growth spurts.
Guest Bedroom
If the guest bedroom doubles as a storage room, a smaller bed like a twin size will ensure the room doesn’t feel too cramped. A twin mattress is also great for use as a spare mattress for guests - it beats sleeping on an air mattress any day of the week!
Small Studios or Apartments
Small bedroom spaces can benefit from a twin bed mattress instead of a larger mattress like a full size mattress. A twin mattress can suit adults who don’t toss and turn and like sleeping cozy.
Master Bedroom
A split-king mattress, which is made up of two twin XL mattresses placed side by side, is a great fit for couples who share a master bedroom. When paired with an adjustable base, a split-king gives each sleeper complete control, minimizing disturbance and maximizing comfort.
Dorm Rooms
Space is critical when planning dorm room decor, so a twin mattress is the best suited mattress size when there is limited floor space available.
Vacation Homes
Vacation homes and AirBnb’s can cater for more guests by using twin beds and bunk beds. Twin beds are more efficient and can be a great selling point when guests make a booking.
