1 Choose Edit > Preferences > Units & Increments (Windows) or InDesign > Preferences > Units & Increments
(Mac OS).
2 To change the origin of the zero point, in the Origin menu under Ruler Units, do one of the following:
• To set the ruler origin at the top-left corner of each spread, choose Spread. The horizontal ruler measures across
the entire spread.
• To set the ruler origin at the top-left corner of each page, choose Page. The horizontal ruler starts at zero for each
page in a spread.
• To set the ruler origin at the center of the spine, choose Spine. The horizontal ruler measures in negative
numbers to the left of the spine and positive numbers to the right of the spine.
3 To change the measurement system used for rulers, dialog boxes, and panels, choose the desired system for
Horizontal and Vertical, or choose Custom and type the number of points at which you want the ruler to display
major tick marks.
If you specify a measurement system other than points, the Increment Every baseline grid value is still displayed in
points. This makes it easier to match text size and leading values, which are displayed in points.
4 To change the value you want used for text size, choose Points or Pixels from the Text Size menu. This option is
especially useful when you’re designing a document for the web.
5 To change the value you want used for stroke weight settings, choose Points, Millimeters, or Pixels from the Stroke
menu. This option is especially useful when you’re designing a document for the web.
6 To change the value you want used for calculating points, specify the desired point size per inch for Points/Inch.
7 Set any of the following Keyboard Increments:
Cursor Key Controls the increment for the arrow keys when nudging objects.
Size/Leading Controls the increment for increasing or decreasing the point size or leading using the keyboard
shortcuts.
