A full-size mattress is a mid-size mattress that is larger than a twin size and smaller than a queen size. This type of mattress is typically 54 in wide and 75 in long.
Full-size mattresses are a good option for people who sleep alone but prefer extra space to stretch out while sleeping. They may also be a good option for couples who do not need as much sleeping space or who have limited floor space.
However, people who are tall and couples who prefer to stretch out while sleeping may prefer a larger mattress.
The following table lists the dimensions of common mattress sizes:
| Twin | 38 x 75 in |
|---|---|
| Twin XL | 38 x 80 in |
| Full | 54 x 75 in |
| Queen | 60 x 80 in |
| King | 76 x 80 in |
| Split king | 76 x 80 in |
| Cal king | 72 x 84 in |
Here we answer some common questions about these mattresses.
Is a full mattress the same as a queen?
No, a full mattress is not the same as a queen mattress.
At 54 in wide and 75 in long, a full mattress is somewhat narrower and shorter than a queen mattress, which is 60 in wide and 80 in long.
How wide is a full-size mattress?
A full-size mattress is 54 in wide.
Can I put a full-size mattress on a bunk bed?
No. Bunk beds typically hold twin-size mattresses, which measure 38 x 75 in. Full mattresses are 54 x 75 in and will be too wide to fit on the bunk bed frame.
Full-size mattresses are a good option for people who have a full-size bed frame, like to stretch out while sleeping on their own, or prefer cuddling with partners.
Most, if not all, companies offer this size of mattress. People can choose from several types of mattresses, such as hybrid and foam, as well as different firmness options, heights, and warranty terms.
