Full Size Bed Dimensions & How They Stack Up to Other Mattress Sizes
Do you live by yourself, or are you squeezed into a tiny apartment with your partner? Does your growing child need a new bed?
These are all situations that favor a full size bed, a popular pick among solo sleepers, couples who live in small spaces, and growing children. That's because a full bed is roomier than a twin size bed yet doesn’t take up as much space as a queen size bed.
But how big, exactly, is a full size mattress, and will it work in your bedroom and your life?
Full size mattress dimensions
Full bed dimensions ride that line between not too big and not too small. Full size beds measure 54 x 75 inches. Standard full size beds have the same measurements as double beds, so you'll often see these two terms used interchangeably.
While full XL mattresses are much less common than standard full mattresses, at times, it is possible to find this size. It measures 54 x 80 inches, making it 5 inches longer than a standard full.

Deciding if a full size mattress is right for you
In order to determine if a full size mattress is right for you, consider the following:
- Who is sleeping in the bed
- Desired comfort level
- Bedroom size
- Body size
- Motion isolation
Who will sleep in the bed
Because a full size mattress is only 54 inches wide, it doesn’t provide adequate space for most couples. In a full size bed, each person will only have 27 inches of space for themselves. That said, if you’re not physically large and don’t mind snuggling, it could be just fine. Additionally, because they’re not especially long, full size beds aren’t a great option for tall folks. A full size bed is just barely over 6 feet in length, so you’re looking at feet hanging over the edge of the bed if you’re a few inches over 6 feet.
Desired comfort level
For solo sleepers, take your sleep position into account—a softer mattress is ideal for side sleepers, a medium firm mattress is good for back sleepers, and a firmer mattress is best for stomach sleepers.
Your room size
If you’re working with somewhat limited space, a full mattress could be right up your alley. For example, if you live in a one-bedroom apartment with a diminutive bedroom or you’re looking to fill a kids’ bedroom, a full mattress could be a good fit. The minimum recommended room size for a full size bed is 10 x 10 feet.
If you have a small bedroom with a full size bed, you may want to avoid nightstands because they take up serious real estate. A platform bed can incorporate storage, so that may be something to consider. Getting creative with wall shelving can also help maximize your space.
Your body size
While full mattresses may be good for heavier individuals, they may not provide enough space for heavier couples. (Learn about the best mattress for heavy people.) However, full XL beds may give extra room to taller people, as their length extends an additional 5 inches for added comfort and personal space.
You’ll be happy to know that full size mattresses are less expensive than their larger counterparts. For instance, full size beds are usually 10%-15% less than queen size mattresses of the same style and brand. A full size innerspring mattress will be the most affordable type of mattress since it tends to run less expensive than other mattress types.
Whether you’re buying a full mattress or another size, if you sleep hot, you may want to skip memory foam since it can trap heat. Innerspring and latex mattresses sleep the coolest, resulting in improved sleep.
For full mattresses and beyond, a memory foam mattress is the best at reducing motion isolation, while on an innerspring mattress, you may feel yourself or your partner moving around, which can disturb sleep.
Full size mattress vs. other mattress sizes
When getting a mattress for a single sleeper or smaller bedroom space, there are a lot of mattress sizes that you can consider. Before finding the right mattress, it's important to consider which size may suit your lifestyle the best.
Double vs. full size
Full size beds and double mattresses are the same. They both measure 54 x 75 inches.
Full XL vs. full size
As the less common version of the full mattress, a full XL measures 54 x 80 inches. If you can track down a full XL mattress, you’ll find that it’s a great option for taller teens or adults and could work nicely in a dorm room if there’s enough space to fit it. The extra length and legroom will ensure that even small sleeping spaces feel comfortable for tall people.
Twin & twin XL vs. full size
Twin and twin XL mattresses are just a little bit smaller than full size mattresses. These are the perfect first "big kid bed" for children, can fit in small spaces, and work well in a child's room. These are also the bed sizes most commonly found in college dorm rooms or in bunk beds.
Even if you're a single adult looking to save some extra space in your apartment, though, it's probably best to opt for a full size. Twin beds will feel cramped for adults and likely be uncomfortable. A full mattress will leave you with plenty of space as a solo sleeper.
Queen vs. full
While a full mattress offers plenty of room for solo sleepers and a cozy situation for couples, a queen mattress provides even more space with 6 additional inches in width. A queen size mattress measures 60 x 80 inches. This size is perfect for a small primary bedroom or a guest bedroom. It's one of the most popular mattress sizes amongst young adults.
A full mattress is an excellent choice for smaller rooms, but a queen will likely be too large and overwhelm a smaller room. Also, full size beds are great for children, but queen mattresses will simply be too big for them.
King vs. full
King size mattresses are the largest on the market right now. There are even multiple different types, including the standard king, split king, and California king mattress. These have plenty of sleeping space for couples and are perfect for large bedrooms.
Single sleepers may find that king size beds have a little too much space. A full size bed will be the perfect new mattress for adults that are sleeping solo.
