Full bed dimensions
A US Full mattress is nominally about 53–54 × 75 inches (134.6–137.2 × 190.5 cm). The one-inch width variation is real, so measure the finished mattress before choosing a frame or fitted sheet.

Full and Double are US synonyms
In current US retail use, Full and Double generally describe the same mattress class. The name does not settle whether a finished product is 53 or 54 inches wide.
Standard Full is not an 80-inch bed
A standard Full is nominally 75 inches long. Full XL adds about five inches of length, while Queen adds both width and length.

Bedding fit
Use the mattress measurements, not only “Full.”
Applicable market labels include Full, Full/Queen. These labels do not guarantee a particular finished sheet, duvet, comforter, blanket, or bedspread dimension.
For a fitted sheet, also measure mattress depth, topper, pad, and extra pocket allowance. For top bedding, choose the side and foot coverage you want.
