The package allows the to user select any font size (via e.g. \fontsize{...}{...}\selectfont), even those sizes that are not listed in the .fd file. If such a size is requested, LaTeX will search for and select the nearest listed size; anyfontsize will then scale the font to the size actually requested.

Similar functionality is available for the CM family, for the EC family, or for either computer modern encoding; the present package generalises the facility.
