How to Measure Window Screens

Measuring and repairing screens for double hung windows and horizontal sliders.

Measuring Existing Window Screens

The best way to measure for new window screens is by measuring the old screens. Take measurements to the outside edge of the aluminum frames. Measure near the corners as screens are sometimes bowed in near the middle of the frame.

Measure a few of the same size screens (if you have more than one) to see if there are slight differences. Use the most common measurements for your replacement screens.

If measureing a full screen, measure the crossbar position from the bottom of the screen frame to the center of the crossbar.


Half Screens

Half Screens are typically found on windows like double hung windows (left) or horizontal sliders (right).
