Monospaced versus Proportional
A monospaced font is a font where all characters have the same width. These fonts are often used to emulate typewriter output for reports, tabular work and technical documentation.
In a proportional font the width of each character, including the space character, varies with the shape of the character. Proportional fonts are easier to read and are preferred for publishing applications.
From proportional to monospaced
To change a proportional spaced font into a monospaced font, follow these steps:
•Select the AutoMetrics command (Tools menu) to force the advance width to be the same for all glyphs including .notdef and combining marks. The only exception is (format) control characters (e.g. .null) which are allowed to be zero-width.
•The advance width of combining marks may be collapsed through OpenType glyph positioning (e.g. using an OpenType single adjustment lookup in the mark feature).
•If necessary, change the outlines of glyphs that are too wide.
•In the Properties dialog (Font menu) on the Characteristics tab set Family Kind to 2 (Latin Text) and Proportion to 9 (Monospaced).
