What Are The Dimensions Of a Full Mattress? Size, Fit, and Practical FAQs
If you’re asking “What Are The Dimensions Of a Full Mattress?”, you’re usually trying to decide whether this size will fit your room, your bed frame, or your sleeping needs. This guide explains the standard measurements, how a full compares to other mattress sizes, and what to consider before choosing one.
What Are The Dimensions Of a Full Mattress?
In most cases, the standard dimensions of a full mattress are:
- 54 inches wide x 75 inches long
- Approximately 137 cm x 191 cm
This size is also commonly called a “double” mattress, and the terms full and double are typically used interchangeably in many regions.

How Does a Full Mattress Compare to Other Sizes?
Understanding What Are The Dimensions Of a Full Mattress is easier when you see it next to other common mattress sizes.
| Mattress Size | Approx. Dimensions (W x L) | Typical Use |
|---|---|---|
| Twin | 38" x 75" | One child or smaller adult |
| Twin XL | 38" x 80" | Taller single sleeper |
| Full / Double | 54" x 75" | One adult or two smaller sleepers |
| Queen | 60" x 80" | One or two adults |
| King | 76" x 80" | Two adults wanting extra space |

Who Is a Full Mattress Best For?
Knowing What Are The Dimensions Of a Full Mattress helps you decide if it suits:
Single Adults
Many solo sleepers find a full mattress offers room to move without taking up as much space as a queen. It can work well in smaller bedrooms, studios, or shared living setups.
Children and Teens
A full mattress is often chosen for older children or teenagers who have outgrown a twin and want extra width. It can also continue to work into young adulthood.
Couples
A full mattress can technically fit two people, but each person has less individual width than on a queen or king. Some couples find it too narrow for long-term comfort, especially if:
- One or both sleepers move around a lot
- There is a large difference in body size
- Extra space is preferred between sleepers
How Much Room Does a Full Mattress Need in a Bedroom?
When thinking about What Are The Dimensions Of a Full Mattress in relation to your room, consider both the mattress and how you move around it.
A full mattress (54" x 75") usually fits best in:
- Smaller master bedrooms
- Guest rooms
- Apartments or shared housing
To keep the room functional, many people aim to leave clear walking space around at least two sides of the bed and room for other furniture like dressers or desks.
What About Full XL or Other Variations?
You might occasionally encounter references to “Full XL”:
- A Full XL is typically around 54" x 80"
- It has the same width as a full, but adds 5 inches of length
This version is less common but can be helpful for taller sleepers who like the width of a full but need more legroom.
Thickness can also vary widely. Some full mattresses are relatively low-profile, while others are much taller. This affects how high you sit or lie above the floor and may influence how easy it is to get in and out of bed.
Do I Need Special Bedding for a Full Mattress?
Because What Are The Dimensions Of a Full Mattress are standardized at about 54" x 75", most bedding labeled “full” or “double” is designed to fit this size.
Here are a few practical points:
- Fitted sheets: Look for packaging that specifies full or double and check the pocket depth if your mattress is especially thick.
- Duvets and comforters: Many are labeled for full/queen together, which usually provides a bit of overhang on a full mattress.
- Mattress protectors and toppers: Choose standard full size for a snug, secure fit.
