If you are using the Adobe Single-line Composer, setting a narrow range in the Minimum
and Maximum values helps achieve a desired result. However, setting a narrow range may
not be beneficial with the Adobe Paragraph Composer, because it decreases the
difference between a reasonable break and a bad break over a range of lines. If you
change the default values for the Adobe Paragraph Composer, make sure the values you
use can accommodate a generous range.
Note: When specifying word spacing, Minimum should be less than or equal to the
percentage set for Desired, and Maximum should be greater than or equal to the
percentage set for Desired.
Controlling spacing and glyph scaling
You can precisely control the way in which InDesign spaces letters and words and scales
characters, which is especially useful in justified text.
To set word spacing or letterspacing:
1 Choose Justification in the Paragraph palette menu.
2 Do either of the following, and then click OK:
For justified text only, type values for Minimum and Maximum to define a range of
•
acceptable spacing. Word spacing values can range from 0% to 1000%. Letter spacing
can range from 100% to 500%.
Type a value for Desired to set the spacing for the selected paragraphs.
•
Note: Entering a Glyph Scaling value other than 100% for Desired for nonjustified text is
the same as entering a value for Horizontal Scaling.
To set glyph scaling:
1 Choose Justification in the Paragraph palette menu.
2 Type values for Glyph Scaling Minimum, Desired, and Maximum. Then click OK.
Traditionally, x-height is the height of
the lowercase letter x. It is also the
height of the body of lowercase let-
ters in a font, excluding the ascenders
and descenders.
Traditionally, x-height is the height of the
lowercase letter x. It is also the height of
the body of lowercase letters in a font, ex-
cluding the ascenders and descenders.
Before (top) and after (bottom) glyph scaling in justified text
Glyph scaling can help in achieving even justification; however, values more than 3%
from the 100% default value may result in distorted letter shapes. Unless you are
trying to achieve a special effect, it's best to keep glyph scaling to values most people
won't notice, such as 97–100–103.
