3.1.3 Font spacing and pitch

You probably first heard the word pitch in connection with typewriters.
Typewritersnormally use monospaced spacing:they give eachcharacter the
same amount of space on the line.
Abouthalf the fontsavailable for laser printers usemonospaced spacingtoo.
Pitch is always expressed as so many characters per inch. Ten-pitch, for
example, means afont with ten characters in each inch of the line.
Typesetters for centuries have used two special sizesof type for most text.
Elitecharacters are 10 pointshigh and print 12characters per inch. Andpica
charactersare 12 pointshigh and pitched at 10characters to the inch. You’ll
often run across these monospaced font sizes inthe laser printing world.
ideally each character inaword should nestleagainst its neighbors sothey
appear evenly spaced. Butadjacent round characters are apt to look too far
apart, while flat-sided characters may appear too close.

Realtypesetters equip certain characters with kerns, letter parts that extend
out to overlap adjoining letters. In this word TJ!PCJthe Jis kerned closely
