Scaling characters
To create characters that are sized correctly and scaled to one another, follow the guidelines
below.
♦ Measure artwork from the height line to the baseline.
♦ Use one standard height to create characters, not to exceed 12" (304.8mm).
♦ Use Arrange > Group to group characters that consist of separate shapes (such as a
lowercase e or an upper case A) to ensure that they are scaled correctly.
♦ Scale characters with rounded tops or bottoms (such as the uppercase O or C) to be
slightly larger than the other uppercase characters. This type of characters should be
scaled to be approximately 2% below the baseline and 2% above the height line.
♦ Scale uppercase and lowercase letters proportionately.
♦ Measure lowercase letters by the height of the x. This is known as the x-height and is
used to verify that all lowercase letters are the same size.
Tip: To make it easier to position characters that should be slightly above the height line or
below the base line, click Layout > Unconstrain to remove the Snap to Guidelines and On-axis
features.
Using Absolute Size to scale characters
The Absolute Size feature can be used to consistently size some characters. This feature is handy
for sizing fonts that consist of all upper case letters without descenders.
To proportionally scale characters, choose Uniform. To scale characters by entering a different
height and width, choose Non-uniform.
Choose Lower Left Corner or Center to Size From. For consistent scaling results, size individual
characters using the same location.
Note: Do not use Absolute Size to scale characters with descenders, such as the lower case letter
y. OMEGA scales characters with descenders using the measurement from the top of the letter
to the bottom of the descender as the height. You must visually scale letters with descenders.
See "Sizing, Slanting, Flipping, and Rotating" for more information on visually sizing
characters.
