Italic was originally developed in the
early sixteenth century as a typeface
based on cursive handwriting. Today’s
italics are still individually crafted type-
faces designed to blend with a specific
roman (upright) typeface.
Oblique (or slanted) type forms,
however, are not designed and
crafted individually but are
mechanically slanted versions of
the roman form from which they
derive.
Pitch refers to the number of characters per horizontal inch (cpi) in a
monospaced typeface. Therefore, the larger the pitch, the smaller the
letter. For example, a ten-pitch typeface
prints ten characters per inch (or 10 cpi)
while a twelve-pitch typeface prints
twelve characters per inch (or 12 cpi).
The example shows ten-pitch and twelve-
pitch Courier.
Stoke weight (light/medium/bold) is the
width (thickness), of the lines (strokes)
that make up a character. The example at
left shows the medium and bold weights
of Palatino.
