Do you know that feeling when your wife shows you two identical dresses and asks, “Which one is prettier?”

Sounds familiar, right?

I felt the same way when I was trying to pick between the Twin and the Twin XL mattresses. They look almost the same, but there are small details that really make them contrasting. Let’s see into all those little details and dissimilarities, shall we?

“Standard twin mattresses (also called “single beds”) are 75 inches long. The Twin XL is 5 inches longer. Regular Twin is perfect for small children, while the extra-long models usually serve to accommodate taller teenagers and adults.”

A Side-by-Side Comparison: Let’s Look at the Dimensions

Twin vs. Twin XL Mattress Sizes

Here’s the deal:

When it comes to Twin vs. Twin XL, the size difference isn’t that significant. However, even a couple of extra inches can make a huge change. So, let’s take a closer look at both of these models.

Twin beds, which are a very popular choice among other models on the mattress market, aren’t that big. The standard size of a Twin mattress is 39 x 75 inches. This might be enough for some sleepers, but it’s most suitable for kids.

“The name “Twin” was given to this bed size because originally these mattresses were designed to be placed side by side, allowing two people to sleep next to each other without lacking the sleeping space.”

The difference between Twin and Twin XL is in the length of each mattress. The extra-long Twin models are 39 x 80 inches, which is perfect for teens and can even accommodate some adults.

You can see now that the difference between these two mattress sizes is quite subtle. Therefore, choosing between them can be tricky. I suggest we look into other details as well.

Finding the Perfect Option: Who Is Going to Enjoy Each Mattress the Most


When looking at the Twin vs. Twin XL comparison (or any other mattresses, actually), you should always keep in mind that one size cannot fit all. A bed can be perfect for some sleepers, but it can also be a real nightmare for others. Therefore, it is important to distinguish for whom each mattress size will be the best choice possible.

Now, let’s start with the Twin. Here’s what you need to know about this model:

  • This size is a perfect option for a child’s bedroom. It is the next step from a crib mattress, so it’s not really suitable for an adult. However, some adults use Twin mattresses to save money.
  • This option is also very reasonably priced, so if you are trying to save some money and don’t want to invest in a larger bed for your small kid, a Twin model would be a great choicebut I would recommend you to choose Twin XL.

“Keep in mind that “standard” sizes are often interpreted differently by different mattress companies and manufacturers. Before you make a purchase, check the measurements of the mattress, just in case.”

The Twin XL is a rather popular option and it is suitable for various purposes and different sleepers:

  • This size is perfect for taller teens and is widely used in their bedrooms.
  • It is great for dorm rooms since this size can accommodate taller sleepers but doesn’t take up too much space.
  • This size can also accommodate taller adults, but keep in mind that it’s quite narrow, so larger sleepers won’t feel comfortable when sleeping on this mattress model.

You can use two Twin XL mattresses to create a King bed for you and your partner, especially if you both have different firmness and comfort preferences. It’s a good trick which is becoming more popular among couples nowadays. 

The Perfect Space: Recommended Room Size

room size for twin mattresses

The good thing about both Twin and Twin XL mattresses is the fact that they can fit in almost any room thanks to their compact size. However, the difference between Twin and Twin XL prevents these models from being equally universal.

Here’s the deal:

You should always take other pieces of furniture into consideration. Despite being rather small, Twin and Twin XL still need some space.

For instance, the recommended room size for a Twin bed is at least 7 x 10 feet. If you need to put two Twin mattresses in one room, the proper size should be at least 10 x 10 feet.  

As for the Twin XL, the room should also be at least 7 x 10 feet. Keep in mind that the extra-long model will occupy a bit more space, so be wise about planning and adding other pieces of furniture.

“The extra-long Twins are a common choice for college dorm rooms and extra guest rooms.”

Let’s get this clear:

The general rule to create a comfortable sleeping space is to leave at least 2 feet of space on each open side of the bed. So, if you need to put two Twin beds in one room, there should be at least 4 feet between them. And if you are planning to make one King bed from two Twins, there should also be 2 feet of space on each open side.

Let’s Talk Numbers: Price and Expenses

Twin vs. Twin XL Prices and Expenses

Price is always an important factor, especially if you have a limited budget. The good news is, with both Twin and Twin XL, you won’t have to spend a fortune to get a new comfortable mattress.

Now, Twin beds are usually very reasonably priced, but this factor depends on the manufacturer. On average, you will pay $100 for a Twin mattress. Although, the prices can vary since there are more expensive models as well.

As for accessories, to get a bed frame for a Twin mattress isn’t a problem at all. Such bed frames are more affordable than the Twin XL ones because they don’t require those extra 5 inches. The sheets and linens for a Twin mattress are also extremely easy to find. They don’t cost that much (on average, $30 for a full set) and come in hundreds of different styles and designs.

“Twin beds are the most popular choice for kids’ rooms or sometimes guest rooms. They are often used for bunk beds as well.”

Now, for the Twin XL, the prices are a bit higher, although the difference isn’t that big. The average cost for a Twin XL mattress is $150 and more. The bed frames for this size are a bit trickier to find because of the added length. As for sheets and other accessories, the range of options is very wide. And it gets better: the prices for the Twin XL bedsheets are also quite reasonable.

The Verdict

Both Twin and Twin XL are quite alike, so choosing between them can be tricky. If I had to make a choice right now, I would’ve chosen the extra-long model since it offers more legroom but doesn’t take up too much space and doesn’t cost too much.

However, you should always take your personal preferences into consideration. If you need a simple but comfy bed for a child, a Twin mattress will be more than enough. You will easily fit it in the room and find the suitable accessories. And if you’re looking for something with more legroom, a Twin XL would be a perfect option that will help you save some money and create a comfortable sleeping space for a taller person. 

In conclusion: Twin size is perfect for children while Twin XL is ideal for adults who are trying to save money or build a King Size bed with 2 Twin XL mattresses.
