monospace.verbatim.font.width length monospace.verbatim.font.width Width of a single monospace font character 0.60em Specifies with em units the width of a single character of the monospace font. The default value is 0.6em. This parameter is only used when a screen or programlisting element has a width attribute, which is expressed as a plain integer to indicate the maximum character count of each line. To convert this character count to an actual maximum width measurement, the width of the font characters must be provided. Different monospace fonts have different character width, so this parameter should be adjusted to fit the monospace font being used.
