Definitions for "Proportional font"
A font that places more characters on a line and requires a different amount of space based on the shape and needs of each character; a proportional font closely resembles printed text.
A proportional font's characters have different widths. Proportional fonts tend to be easier to read than fixed-width fonts. The user may select which proportional font to use as a base font.
Proportional fonts are fonts whose characters take up more or less space depending on the individual character. For example, an "i" will take less space than an "o" will. Proportional fonts are also called variable width fonts. Common examples include Times and Helvetica. Fixed width fonts are fonts whose characters all take up the same amount of space.
