Twin VS. Full – What’s The Difference?

All of us who once had to find the right bed for ourselves, and it’s not as easy to do as it may seem at first glance. We have to look at the size of the room, the potential position of the bed. Even the height and the type of mattress must not be overlooked. However, the very first step is finding the right size. After all, it’s not great if you buy a huge bulky bed and it doesn’t fit in your small and cozy room, right?

So let’s discuss the difference between the two smaller bed options available on the market—the Twin and the Full. Let’s have a look at both types of beds, their benefits, disadvantages as well as prices and some room size recommendations.

A Twin Mattress

Twin beds are also known as Single beds, which are intended for one person only. They are mostly used for children’s or teenagers’ rooms. But they’re also a common choice for guest rooms, as they can easily fit into a bedroom of any size – even a very small one. 

Another common place to see twin-sized mattresses are in rooms shared by more than one person, such as bunk beds in kids’ rooms or hostels. Because they’re so conveniently compact, they are are a pretty versatile option. However, this option is only comfortable if you’ll be sleeping alone.


Twin size mattresses are available in a standard twin size and twin XL size. 

Twin size dimensions: 38 x 75 inches.

Twin XL dimensions: 39 x 80 inches. 

As you can see, the twin XL is one inch wider and five inches longer compared to a standard twin bed. It’s a great choice for a teenager who is on their growing spur, or a guest room as it can still fit an adult comfortably. A standard twin is best left for children’s rooms.

Room Recommendation 

It is recommended to plan ahead and choose the best placement for the bed in the room before the purchase. If possible, it’s worthwhile to make a visual layout of the room. This way you can visualize the position of the bed and compare it with other possible options. 

Keep in mind that paying attention to the measurements of the bed and the size of the room is also crucial. You also need to make sure that the bed is not too large or too small for the room. For example, A twin XL bed in a small, fully furnished room may be hard to place. You may even need to move some of the furniture out just so there’s enough space. While a standard twin bed in a master bedroom might get lost. It would aesthetically look too small. 


The price of your twin bed will depend on a few different aspects:

  • The brand

As we all know, labels can cost money. Sometimes, buying a very expensive mattress won’t get you better quality sleep. You might only be paying for the brand’s name. Research your brands, look into the structure of their mattresses and make an informed decision.

  • Materials and type of bed

All-foam mattresses are cheaper to manufacture so they go for a lower price. Latex, however, takes a long time to harvest, manufacture and produce. Therefore, latex mattresses tend to be much more expensive. Do your research, and choose the type of bed that will suit your needs.

Those two points aside, a twin bed can cost anything from $120 to $1000 and more. 

Pros & Cons 


  • Fits children and teenagers perfectly
  • Can be used in guest rooms
  • Can be not that expensive
  • It takes up little space in the room


  • A twin bed is suitable for single sleepers only
  • It might be too narrow for some adults.

Full Mattress

Size-wise, full beds are in between twin beds and queen beds. They’re wider and more spacious when compared to twin mattresses, yet take up less room when compared to queen mattresses. 

Full-sized beds are the most popular among single sleepers who like to have more space (such as restless sleepers). Or young couples who live in smaller apartments. 


Full beds are divided into Full standard (sometimes also called Double) and Full XL beds (which are also called Double XL). The dimensions are as follows:

Full Standard bed: 54 x 75 inches.

Full XL bed: 54 x 80 inches.

Full XL beds come at the same width as Full Standards, but they are 5 inches longer. Compared to twin beds, Full beds are 6 inches wider. 

Room Recommendation 

Same as with twin beds, the most important thing is to make sure that your new Full bed fits in your bedroom well, aesthetically and practically. If you have a room that is big enough, then having a Full-size bed will not cause any problems as there will be enough space to move around. However, if you’re considering cramming a Full-sized bed into a tiny room, you’re better off going for a twin-size instead.


Depending on the aspects mentioned previously, a Full-size bed may cost anything from around $120 to more than $1200. It all comes down to what you’re looking for and how much you are willing to spend. 

Pros & Cons 


  • Fits an adult very comfortably
  • Can fit a couple
  • Prices are very similar to those of twin beds


  • Doesn’t fit in very small rooms

Which is Better: Twin or Full?

It all depends on the situation. If you will not be sharing your bed, and your bedroom is relatively small, then a twin-sized mattress would be a better choice. But if the bed is for a couple or an averagely sized guest room, the Full-sized mattress would provide more comfort. Evaluate the situation, pay attention to the measurements and you will make your choice. 

As for the price, the cost of twin beds and Full beds don’t differ all that much. It’s mainly the size that you would need to pay attention to.
