4 Choose a line spacing option from the Line spacing pop-up menu that appears when
you click the text below the line field.
Line spacing pop-up
menu: Click the text
below the Line field
and choose a line
spacing option.
Line field: Type a value
(or click the arrows)
to specify the space
between lines of text
in a paragraph.
Standard line spacing (Single, Double, Multiple): The space between lines is
proportional to font size. Use this when the relative distance between ascenders
(parts of letters that extend to the top of the line) and descenders (parts of letters that
extend below the line) should remain fixed. Single sets line spacing to single-spaced,
and Double sets it to double-spaced. Use Multiple to set line spacing values between
single and double, or greater than double.
At Least: The distance from one line to the next will never be less than the value you
set, but it may be larger for larger fonts to prevent overlapping text lines. Use this
when the distance between lines should remain fixed, but overlap is not desired if the
text gets large.
Exactly: The distance between the baselines.
Between: The value you set increases the space between the lines, instead of
increasing the height of the lines. By contrast, double-spacing doubles the height of
each line.
Setting the Spacing Before or After a Paragraph
You can increase or decrease the spacing before or after paragraphs.
To adjust the amount of space before or after a paragraph:
1 Select the paragraphs or text box you want to change.
2 Click Inspector in the toolbar, click the Text button, and then click Text.
3 Drag the Before Paragraph or After Paragraph sliders to achieve the look you want, or
specify a precise value (for example, 5 pt) in the adjacent fields.
If you set the the After Paragraph spacing to a different value than the Before
Paragraph spacing of the subsequent paragraph, the higher value will be used. For
example, if the first paragraph has an After Paragraph value of 12 points and the
following paragraph has a Before Paragraph value of 14 points, the spacing between
paragraphs will be 14 points.
