Have you ever tried to use  Adobe® Photoshop® Print Size preview and been bewildered on why it fails? If so, this might help explain things to you.  Adobe® Photoshop® doesn’t know your screen resolution so it uses a default 72 screen resolution setting. 

If you go to your  Adobe® Photoshop® preferences (ctrl+k) and pick the Units and Rulers tab you’ll see a box that reads Screen Resolution. You’ll more than likely, unless someone has changed it, see a 72 in the box.  You need to change the setting, one time, on each of your production monitors.

Take out a tape measure and measure your screen, but don’t include your monitor frame. When measuring don’t measure diagonally; measure either horizontally or vertically. In my case my screen measures 20.5 inches horizontally.
