How Many Inches Is a Full Size Bed?

A full size bed is one of the most popular mattress sizes for teens, solo adults, and guest rooms, sitting right between a twin and a queen in overall space.

Quick Scoop

Standard full size bed dimensions: 54 inches wide × 75 inches long.

Also known as a “double” bed in many listings.

Great for: solo sleepers who want extra room, growing teens, and guest rooms.

Room size sweet spot: often recommended for rooms around 10 ft × 10 ft.

Exact Dimensions in Inches

For most mattress brands in North America, a full size bed is:

Width: 54 inches
Length: 75 inches

So if you’re measuring your room or shopping for sheets, that’s the key number: 54" × 75".

Do note:

Some manufacturers may be off by an inch or so, but 54×75 is treated as the industry standard.

Mattress thickness is not standardized; many full mattresses range roughly from 8 to 14 inches deep , so your fitted sheets may need “deep pockets” for thicker models.

Mini Guide: Is a Full Size Right for You?

Think of a full as the “upgrade from twin” when you want more stretch-out room without committing to the footprint of a queen.

A full size bed tends to work well if:

You’re a solo sleeper who wants extra space to roll around.

You’re furnishing a guest room and want something more generous than a twin.

Your bedroom is on the smaller side (around 10×10 ft), where a queen might feel cramped.

Two adults can technically share a full, but it will feel cozy to tight , since each person gets only about 27 inches of width.

Little “Story” Example

Imagine you’re planning a guest room makeover in a 10×10 room.
You want space for a small desk and maybe a dresser, but you also don’t want your guests squeezed into a tiny twin.
A queen starts to dominate the room and makes it harder to move around.
So you pick a full size bed (54" × 75") , which gives your guests a genuine “real bed” feel while still leaving walkways clear and room for a chair and side table.
