Breaking up sections of a document by typing individual characters to form a line is a time-consuming and potentially error-prone method. Instead of doing that, learn the two ways Microsoft Word has for inserting different styles of horizontal lines.

Inserting a Line Using AutoFormat

The quickest and easiest method for inserting a line into a Word document involves the application's AutoFormat feature, where typing just a few characters instantly creates the type of line that you're interested in. To get started, first place your cursor in the location that you'd like to insert a line.

Next, type three of a particular character and hit the Enter or Return key. Your line will automatically be created in the spot chosen. The following characters can be used to create a line via AutoFormat. Reference the accompanying screenshot below to see what each of these line types actually looks like in Word.

  • Plain single line: Three hyphens (---)
  • Plain double line: Three equal signs (===)
  • Broken/dotted line: Three asterisks (***)
  • Bold single line: Three underline symbols (___)
  • Wavy line: Three tildes (~~~)
  • Triple line w/thick center: Three number signs (###)

  5. A basic horizontal line should now appear in your document. Double-click on the line if you'd like to edit its appearance.

  6. If you chose to double-click, the Format Horizontal Line dialog should now be displayed. From here you can modify the width, height, and color of your line as well as adjust its alignment.
