Mattress size is an integral and underrated part of bedroom decoration. Many people get confused when trying to differentiate between twin vs full mattresses since they’re very similar in size. That’s why we’ve created this guide to help you learn exactly how you can differentiate between twin vs full mattresses, why you might need one more than the other, and what each kind is best for.
Since it is wider than a twin mattress, full mattresses are able to provide a little extra space to sleepers who need it. Here’s everything you need to know about twin vs full mattress sizes - happy shopping!
Mattress Dimensions: Twin vs Full
One of the main differences between a twin and a full size mattress is their actual mattress dimensions.
A standard twin mattress comes in at 38 inches by 75 inches, with a surface area of 2,840 square inches. Many mattress companies also offer a twin XL, which is slightly larger at 38 inches by 80 inches, and a surface area of 3,040 square inches.
Full mattresses on the other hand, come in at 53 inches by 75 inches, with a significantly larger surface area of 3,957 square feet. A few mattress companies also offer full XL mattress sizes, which are five inches longer than the standard option.
How To Choose Between A Twin vs Full Mattress
The mattress dimensions of a twin vs full mattress might not be the only thing you need to take into account when you’re trying to choose between the two. Other reasons you might opt for a twin bed or full bed include your bedroom size, costs, what you’re planning to use your mattress for, and the availability of accessories.
Bedroom Size
Your bedroom size has an obvious impact on how you choose between a twin vs full mattress size. Small bedrooms that have dimensions of less than 10 feet by 10 feet are better off using a twin since they just don’t have enough space for a bigger bed. This is why they work particularly well for children’s rooms, or studio apartments that lack too much free space.
For full beds, a room that is 10 feet by 12 feet or larger will work best. These sizes are a popular choice for spare rooms that need to be used as guest bedrooms or small bedrooms in general.
When you’re choosing your mattress while factoring in your bedroom size, it’s worth keeping in mind that most interior designers recommend you ensure there’s a minimum of two feet between your bed and any other piece of bedroom furniture in your room.
A cramped bedroom doesn’t just look bad, it’s also more likely to be uncomfortable. Stuffy bedrooms can cause you to overheat at night, and even lead to poorer sleep, so be sure to pin down the right mattress size for your space - the best mattresses stay comfortable no matter what their size is.

Cost
If you’re on a tight budget for a new mattress, then it’s important to know twin beds are probably the most cost-effective choice available. Here’s an example of the price difference between the different Puffy mattresses:
| Twin | Full | |
| Puffy Cloud | $599 | $899 |
| Puffy Lux | $899 | $1,299 |
| Puffy Royal | $1,249 | $2,149 |

Many mattress companies (including Puffy) offer financing options that allow you to split up your payment. This is a good option if your needs are more in line with a full mattress, but you just don’t have the finances for it as of yet.
Bedding & Accessories
Another factor to keep in mind when you’re trying to pick the right mattress size is bedding. Both twin and full-size mattresses are standard and easy to find in your local home store.
Bedding for sizes such as full-XL might be slightly more challenging to find since they’re not really a standard size. It’s also worth remembering that bedding and any sleep accessories you might want for your bedroom are going to be more expensive in larger sizes, so if you need to be on a tighter budget, a smaller option might be more suitable for you.
Uses
Twin beds are most commonly used for children graduating to a ‘big kid bed’ after sleeping on smaller, crib-size mattresses. Twin beds can be a really versatile option for a child’s room, and they’re also compact enough to be stacked for bunk beds. Even a great mattress will need changing after 12 years, so this is the perfect choice for growing children.
Full mattresses are ideal for single sleepers, or couples on a tight budget. If you find yourself pressed for space in your first home, a full mattress is a comfortable option that will still allow you to have some breathing room. Full mattresses also work great in college dorm rooms, or in guest rooms.

If you’re trying to decide between a full vs twin bed, a few things to keep in mind include cost, availability of bedding and accessories, bedroom size, and usage. Both twin-sized mattresses and full-sized mattresses are equally comfortable options, so choosing what’s right for your unique needs is more important.
