Use the Adjust Lines Within Margins dialog box (Master Guides & Grid > Adjust) to change the number of grid lines that fit within the margins of a master page. Many of the controls in this dialog box are also in the Text Settings tab; changes are reflected in both locations.

Use the Adjust Lines Within Margins dialog box to adjust grid settings for a master page.

• The Lines per page field displays the number of lines on a page. This value updates as you make changes.
• Click + or – next to a field to increase or decrease the number of lines on the page in one-line increments. For example, if the Lines per page value is 50, the Font Size value is 12 pt, and vertical font scaling is 100%, when you click + next to Font Size, the Lines per page value increases to 51 and the Font Size value decreases to 11.765 pt.

• The increment bar displays a percentage (from 0 to +1) to indicate the fraction by which a grid pattern does not fit on the page. If the grid increments align perfectly, the increment bar displays 0. If the grid increments do not align perfectly with the page, an estimate of the fraction displays in the increment bar.

• Click Reset to restore the values in all fields to the state they were in before you displayed the dialog box.
