How to measure screen door width

How do I measure for the correct patio screen door width so that the bug flap operates properly? I'm guessing that the screen door width should reach to about half the width of the stile of the fixed door. I just want to make sure so that I dont't order the wrong size.

Hi Jim;

The width of the screen door is usually identical to the width of the sliding patio door panel.
