Ligatures
Ligatures occur when two or more letterforms are joined
as a single glyph. The most common English combinations
usually begin with the letter “f.” The word “firefly” has two
opportunities for ligatures: “fi” and “fl.” In the example to
the right, the two individual letters are replaced with a
single letterform. The bulb of the “f” combines with the
dot in the “i,” creating a unique letterform that replaces
two characters. Common ligatures are fl, fi, , , , .
Kerning
Kerning adjusts the space between individual letters. A well-
kerned font reduces the amount of visually awkward gaps
between letters. Turn auto-kerning on in your presentation
software. Common letters that need to be kerned manually
are capital letters: A, R, T, V, W, Y.
Look at the word “WAR”. It is not kerned. You can see how
the slant of the “W” is parallel with the slant on the “A” but
there’s a large gap between the two letters. Compare this
with the slide on the opposite page where the word “
WAR”
is properly kerned.
Letterspacing
Letterspacing—also called tracking—refers to the amount
of space between letters that affects the overall density of
a word. The slide on the opposite page with the word
“spacious” has loose letterspacing.
