How-To Geek  Monospaced Font  A monospaced font, or non-variable
width font, is a font wherein each character in the font set is
given equal spacing regardless of the size and shape of the
letter. A common monospaced font is Courier (aka the typewriter
font). Monospaced fonts yield text that takes up more space on
the page because there is no mechanism for adjusting the spacing
and fitting the letters closer together based on their shape.
