Twin vs. Twin Xl Mattress Comparison: Which Is Best? Update 07/2024

Choosing the proper mattress size is the first step in the process of finding the right mattress for you. If you’re shopping for a bed for a child or yourself, a twin mattress should be plenty for your needs. Is there a “twin XL” option? When comparing twin XL with regular twin, which is ideal for your needs?

There is only one difference between a regular twin and an XL twin, and that difference is 5 inches. As a result, taller individuals may consider ordering a twin XL. When it comes to width, there is no difference between the two bed sizes (38 or 39 inches), so they are only suitable for single sleepers.

Twin Twin XL
Dimensions 38” wide, 75” long 38” wide, 80” long
Surface Area 2,850 square inches 3,040 square inches
Best For Single sleepers under 6’ tall Single sleepers over 6’ tall
  • Cheaper than Twin XL
  • Accessories, sheets, bed frames, etc. are more widely available
  • 5” extra length accommodates taller people
  • Same length as a Queen mattress
  • Only 75” long; will feel cramped for tall people
  • More expensive (typically ~$100 more than Twin)
  • Can be harder to find accessories in Twin XL size

Twin and twin XL sizes are distinguished by their length. At 38-39 inches broad, both variants are identical in breadth, but the length varies by a full five inches.

It is recommended that singles under the height of 6 feet sleep on mattresses that are the width and length of a Twin.

If you’re a single sleeper over six feet tall, or if your child or teen is growing, the Twin XL mattress measurements (38 inches wide by 80 inches long) are for you.

Table above provides a brief overview, but there are additional considerations to keep in mind when making a purchase.

What’s a Twin Size Mattress?

To put it another way, a twin mattress is equivalent to one single bed, and it has dimensions of 38″ x 74″. To date, the twin mattress is the tiniest and most compact accessible standard size. Bunk beds are a terrific alternative for families with more than one child, as they free up additional floor space for play and other activities.

Adults with smaller living quarters, such as studio apartments, may prefer the smaller size of a twin or single bed for their use as a guest bed.


There is a wide range of price points for a twin mattress, from $100 to $1500. Due to the use of exclusive sleep technology and organic materials, the cost of high-end mattresses is more expensive.

Other Mattress Sizes

You may want to consider other mattress sizes, such as a full or queen mattress in the event that a twin or twin XL mattress is too tiny for your main bedroom.

Full Size

Full-size mattresses are 54 inches wide by 75 inches long, allowing for extra room to spread out in both width and length. Teenagers and college students might both benefit from having a bed that is a full size. They’re also a good option for single adults on a low budget and with a limited amount of area to work with.

Queen Size

Queen mattresses are 60 inches wide by 80 inches long, making them a popular choice for single adults. Queen-sized beds offer plenty of area to spread out, making them ideal for those who sleep in a variety of positions. For couples, queen-sized mattresses are also an excellent choice, albeit they are less spacious than king-sized beds.

King Size

The largest conventional mattress size, the king, is 76 inches wide by 80 inches long. A king-sized bed is ideal for couples since it provides plenty of room for privacy. If you put two XL twin mattresses next to each other, they’ll measure the same. Individually tailored mattresses are also available for couples who like the comfort of their own bed.

California King Size

Compared to a king-sized mattress, the length of a California king mattress is 72 inches by 84 inches, making it slightly longer. For couples who prefer to sleep close together, California king beds are an excellent choice. Split California kings are an option for those who prefer them, but they aren’t as common as the split king.

What’s the Difference Between Twin and Twin XL?

For those who require a smaller bed yet don’t have a lot of space, there are a few options to consider. For a child, a guest room, or a college student, a twin or twin XL bed with luxurious twin bedding is the best option.

A king-sized bed may also be created in the master bedroom using twin and twin XL mattresses, which can be pushed together for couples who like to sleep on different beds. It’s possible to have a twin or twin xl mattress that’s both luxurious and supportive at the same time.

There is a significant size difference between twin and twin XL beds, despite the fact that both mattresses look the same. A twin XL mattress provides a more pleasant night’s sleep, despite the fact that the difference in size may not seem like much.

The size of the twin XL is, in fact, its most notable feature. In the moniker, “XL” refers to the fact that the mattress is longer than a standard twin. Teens and adults prefer twin XL beds because of its extra-long length, whereas conventional twin beds (also known as single beds) are better suited for younger children or those with small quarters.

What is the Size Difference Between Twin & Twin XL Beds?

Despite their similar breadth, the twin XL mattress is longer. Knowing the dimensions of each of these common beds is essential to ensure that you get the correct size bed, as well as to guarantee that luxury sheets and bedding fit your bed appropriately.

The twin XL mattress is only 5 inches longer, but it makes a huge difference in the comfort of the bed. Twin XL is a popular choice for students who live in dorms or modest apartments because of its size. The twin XL bed is exactly half the size of a queen-sized bed, making it ideal for a single person. Twin XL beds are also the same size as king-size beds, so you can fit two of them together.

Will a Twin XL Mattress Fit a Twin Bed Frame?

In spite of the 5″ difference in length between the twin and the twin XL mattress, the conventional twin size bed frame will not fit the twin XL mattress because it is too long. Consequently, mattresses of the exact same size must be used in all enclosed twin-size frames and units (such as bunk beds, daybeds, and loft beds).

Twin-XL mattresses can fit on the standard-sized twin box spring, but they may be uneven and interfere with your sleep if they hang out too far from the box spring’s edge. It is also possible that the mattress will be harmed owing to the additional stress it is under as a result of improper use on a regular basis. Use a twin XL frame with your twin XL mattress for the greatest results.
