When displaying a Layout at a 1:1 ratio, one inch displayed does not equal one inch measured on the screen

Description

When the Layout is displayed at a 1:1 ratio, what the screen calls an inch does not equal a measured inch on the screen.

Cause

All display calculations in ArcView use dots per inch of the screen.

Solution or Workaround

1. Measure the width and the height of the portion of the screen that is lit by pixels (the measurement may be 12.5 x 9.0).

   A. Activate the Project window.
   B. Click the Scripts icon.
   C. Click New.
   
   
3. Enter the following line of code.
   
   

   Code:
   System.SetScreenSize Inches(12.5@9.0)

   
   
4. Click the
   
   button to compile the script.
5. Click the
   
   button to run the script.
