How To Measure Your Windows
Check out our 4 easy steps to measuring your windows and selecting the correct window guard model. You can also download a printable version here. If you have any questions or concerns with your windows or size, contact us. We are here to help make sure you select the correct guard and install with ease.
Step 1
Determine Installation Placement
Measure the depth from the window face to the frame edge to determine inside or outside window frame installation. Guard end posts are 3/4” square and require a minimum of 3/4” depth for installation.
Install inside window frame when depth is grater than 3/4”
Install outside window frame (wall or window molding) when depth is less than 3/4”
Step 2
Measure Window Length
Measure the length of where the guard will be installed. This will be the width for horizontal installs or the height for vertical installs.
Step 3
Measure Window Opening Space (Danger Zone)
Measure the height or width of the fully open window space (Maximum Opening/Danger Zone). The entire window frame for double-hung, double-slider and casement windows should be guarded completely.
Step 4
Select Guard Size
Take your two measurements and use our Window Guard Model Number Sizing Chart to select the guard size you will need for each window.
Install Do's & Don'ts
-
Do's
Window guards should cover the maximum window opening space in single- or double-hung windows. We recommend using window stops if you do not guard the full window.
-
Don'ts
Don't allow more than 4" of open window/screen space. Cover the entire window or use window stops to prevent window panes from exposing more than 4" of open window/screen.
