gtroff
uses two dimensions with each line of text, type size and
vertical spacing. The type size is approximately the height of
the tallest glyph.21 Vertical spacing is the amount
of space gtroff
allows for a line of text; normally, this is
about 20% larger than the current type size. Ratios smaller than
this can result in hard-to-read text; larger than this, it spreads the
text out more vertically (useful for term papers). By default,
gtroff
uses 10 point type on 12 point spacing.
The difference between type size and vertical spacing is known, by typesetters, as leading (this is pronounced ‘ledding’).
