The size of a fitter's file refers to the length of the file body.

The specifications of special-shaped files and plastic files refer to the full length of the file.

The fitter should file the body (the distance from the tip of the file to the shoulder of the file). The length is expressed in several specifications of 100-150mm, 200-300mm, and 350-450mm.

The full length of special-shaped files and plastic files is the specification size. The basic dimensions of the file mainly include width and thickness. For round files, it refers to its diameter.
