how bigs a full size bed
A standard full (also called double) mattress is about 54 inches wide by 75 inches long (roughly 137 cm by 191 cm).
Quick Scoop
- Width: about 54 inches (4.5 feet).
- Length: about 75 inches (6.25 feet).
- In centimeters: about 137 cm by 191 cm.
- Typical full bed frame footprint: roughly 56–60 inches wide and 76–80 inches long, since frames stick out a bit past the mattress.
