fixed-pitch fonts See font, monospaced.
font The complete set of a given size of type, including
characters, symbols, figures, punctuation marks,
ligatures, signs, and accents. To fully describe a font, you
must specify seven characteristics:
1) typeface
2) spacing (proportional or monospaced)
3) type size (12 point, 14 point, etc.)
4) scale factor (character height/width ratio)
5) type style
6) character weight
7) character proportion (normal, condensed, expanded)
font, landscape A font printed parallel to the long edge of a page.
font, monospaced Also called fixed-pitch fonts. Every character, regardless
of horizontal size, occupies the same amount of font
pattern space. All monospaced fonts use specific pitch
size settings. Monospaced fonts are sometimes used
when strict character alignment is desired (tables, charts,
spreadsheets, etc.).
font name See typeface.
font pattern The matrix of pixels which represents a character,
symbol, or image.
font, portrait A font printed parallel to the short edge of a page.
font, proportional A font in which the width of a character cell varies with
the width of the character. For example, [i] takes less
space to print than [m]. Using proportional fonts generally
increases the readability of printed documents, giving
text a typeset appearance.
