# Use rulers

Comic Life provides horizontal and vertical rulers to help you lay out text and elements in your document. For script editing only the horizontal ruler is available for you to change and add tab stops. For comic page layouts both rulers are available.

You can set the ruler to use different increments (points, inches, centimeters), and place 0 (zero) at the center of the ruler.

Do one of the following:

- Click in the toolbar, then choose Show Ruler (or Hide Ruler).
- Choose View > Show Ruler (or Hide Ruler) from the View menu at the top of your screen.

When you change a unit setting for rulers in Comic Life, it applies to all documents. You can change the settings at any time, even if you have a document open.

1. Choose Comic Life > Settings (from the Comic Life menu at the top of your screen), then click Rulers at the top of the settings window.
2. Click the Ruler Units pop-up menu, then choose an increment (Points, Centimeters, Millimeters, or Inches).

You can place 0 (zero) at the center of the ruler so that ruler units increase to the left and right.

1. Choose Comic Life > Settings (from the Comic Life menu at the top of your screen) then click Rulers at the top of the settings window.
2. Select the "Place origin at center of ruler" checkbox.
