In this guide, we explain full mattress dimensions, compare them with other mattress sizes, and discuss whether a full-size mattress is the right choice for your bedroom, guest room, apartment, or hotel project.

Is a Full Mattress the Same as a Double Mattress?
Yes. A full mattress and a double mattress refer to the same mattress size.
The term “double mattress” was commonly used because it offered more sleeping space than a single bed. Today, “full mattress” is the more popular term in North America.
Who Should Choose a Full Mattress?
A full-size mattress is a practical option for many sleepers.
Single Adults
A full mattress provides more space than a twin bed, making it suitable for adults who want extra room to move during sleep.
Teenagers
Many teenagers outgrow twin beds, and a full mattress offers additional comfort without taking up too much bedroom space.
Guest Rooms
A full-size mattress is a popular choice for guest rooms because it can comfortably accommodate one adult and occasionally two people.
Apartments and Smaller Bedrooms
Because of its compact footprint, a full mattress fits well in apartments, studios, and smaller bedrooms.
Full Mattress vs Queen Mattress
Many buyers compare full and queen mattresses before making a decision.
Full Mattress
- Width: 54 inches
- Length: 75 inches
- Better for small rooms
- Lower cost
- Ideal for single sleepers
Queen Mattress
- Width: 60 inches
- Length: 80 inches
- More sleeping space
- Better for couples
- Suitable for larger rooms
A queen mattress offers six additional inches in width and five more inches in length, which can provide more comfort for two sleepers.
Full Mattress vs Twin Mattress
A full mattress is significantly wider than a twin mattress.
| Size | Width | Length |
|---|---|---|
| Twin | 38 inches | 75 inches |
| Full | 54 inches | 75 inches |
A full mattress provides 16 inches of extra width, making it more comfortable for adults.
Is a Full Mattress Big Enough for Two People?
A full mattress can accommodate two people, but sleeping space may be limited.
Each person gets approximately 27 inches of sleeping width, which is less than the personal space available on a twin mattress.
For couples who prefer more room, a queen mattress may be a better choice.
Room Size for a Full Mattress
The recommended minimum room size for a full mattress is:

This allows enough space for walking, bedside furniture, and storage.
