Line spacing in Word 2003 can help improve readability. In Word paragraph spacing can make documents look cleaner too.
You can use the At Least, Exactly, and Multiple options in the Paragraph dialog box to customize your line spacing. If you select one of these options, you will need to use the At: box to further define your selection.
When you make a line spacing change, it affects only the text in a paragraph that contains the insertion point.
