1)  Measure the height inside of the window frame. 
 
2) Measure the depth of the window frame where the posts will be mounted (inside top and bottom of window frame).
  • If there are shades, blinds, etc. mounted in the frame that may interfere with the guard or if the depth of the window frame measures less than 3/4 inches, the guard will need to be mounted on the outside of the window frame (on the window trim or wall). Add at least 1-1/2 inches to the inside window frame height measurement. The extra 1-1/2 inches is the width of both end posts.
