Choosing the right mattress size is important for a good night’s sleep. We’ll provide an in-depth look at the twin XL size mattress — its size and benefits and how it compares to other mattress sizes. Whether you’re shopping for yourself or your kids, understanding the dimensions of a twin XL mattress will help you make the right choice.

What Are the Dimensions of a Twin XL Mattress?

A standard twin XL mattress measures 80 inches in length and 38 inches in width. It’s 5 inches longer than a regular twin, which measures 75 inches in length. This extra length makes it a good fit for taller individuals who need that extra foot room.

If you’re curious about the thickness, twin XL mattresses can also vary, usually ranging between 5 to 12 inches. They come in a variety of mattress types, including innerspring and memory foam. Innerspring mattresses use a coil system for support, providing a traditional bounce and airflow, which can be beneficial for hot sleepers. Memory foam, on the other hand, was originally developed by NASA to cushion astronauts during takeoff and offers a more contouring support that adapts to your body shape. The dimensions of the bed frame for a twin XL usually match the mattress dimensions but may add a few inches for decorative features.

Twin XL vs. Twin Mattress: What’s the Difference?

Both a mattress in twin size and twin XL mattresses are 38 inches wide, but the twin XL is 5 inches longer. That means that sheets for a standard twin won’t necessarily fit a twin XL mattress. The extra length of the twin XL provides additional comfort for taller individuals, making it an ideal mattress for teenagers and college dorm rooms.

If you’re choosing between a Twin and a twin XL, consider the room size and who will be using the mattress. For kids and smaller rooms, a regular twin might be sufficient. But for teenagers or guest rooms, a twin XL offers that extra length without consuming too much additional space.

Why Choose a Twin XL Mattress?

The twin XL mattress size is particularly beneficial for taller individuals — generally those who are over six feet tall. The extra length ensures that your feet won’t hang off the end of the bed. Think of a teen in a small room or a college freshman living the dorm life. Another advantage is that two twin XL mattresses together make a King bed. This is a good option for couples who have different mattress preferences. Each person can choose the twin XL that suits them, and then they can be placed side by side.

How Do Twin XL Mattresses Compare to Other Sizes?

When shopping for a new mattress, you’ll come across various mattress sizes. Here’s a quick rundown of popular mattress sizes to help you compare. 

• - King Mattress: A king size mattress is significantly wider, measuring 76 inches in width. However, it has the same length — 80 inches — as a twin XL. Two twin XLs equal one king mattress. 
• - Queen Mattress: The queen size mattress is wider than a twin XL at 60 inches but shares the same length — 80 inches.
• - Full Mattress: A full size mattress is 54 inches wide and 75 inches long, making it shorter but wider than a twin XL.

Remember, if you’re considering mattress sizes and dimensions other than the twin XL, you’ll also need to think about room size and whether the mattress will comfortably fit.

Twin XL Size Bedding Accessories

When it comes to twin XL bedding accessories, it’s important to note that options like linens, bed sheets and mattress protectors are less readily available than for a standard twin bed. This is mainly because of the twin XL mattress dimensions. As mentioned, both the Twin and twin XL have the same width as a standard twin — 38 inches — but the twin XL is five inches longer than a twin.

Because of this extra length, standard twin sheets won’t fit a twin XL mattress. That’s why you’ll need to look specifically for sheets and linens labeled for twin XL beds. It may take a bit more effort to find these, but it’s worth it to ensure a good fit, especially if you need those extra five inches for added comfort.

So if you need the extra length that a twin XL offers, investing in the right bedding accessories is essential. Make sure to read the labels carefully. If in doubt, measure the items before making a purchase or ensure there is an easy return policy in place. This will save you time and effort in the long run, ensuring a better fit for your twin XL mattress.

Room Size Requirements for a Twin XL Bed

A twin XL mattress is among the best beds for small bedrooms. It is a good choice for room sizes where you can’t fit a queen or full size bed and situations that call for extra length for taller sleepers. For a twin XL bed, a room that’s at least 8 feet by 10 feet is typically sufficient. This allows for walking space and additional furniture. 

Is a Twin XL Right for Your Kid’s Room?

For older kids and teenagers, a twin XL is often a better choice than a regular twin because of the extra length. It’s a perfect transitional mattress size that can last them into their college years when they’ll need the extra-long sheets for dorm beds.

Choosing the Right Mattress: Final Thoughts

Making the right mattress decision requires considering various factors including size, comfort level and room dimensions. Understanding the specifics of a twin XL mattress can help you make an informed decision. Whether for a child’s room or one half of a king size bed, the twin XL offers versatility and comfort for a variety of situations
