To measure your Window Screen, you can use a traditional tape measure, or for added convenience, you can use a measure app available on most smartphones. These apps utilize your device's camera to measure objects and distances, allowing you to easily measure the width and height of your door. However, for precise measurements, especially for larger doors, a tape measure may be more accurate. Measure to the nearest 1/8 of a inch for a perfect fit.

To Measure your undamaged existing Window Screen accurately, Measure at the corners Outside edge to Outside edge across the top and down the side. Measure to the nearest 1/8th inch. GOLDEN RULE - Measure twice to ensure order accuracy.

If you don't have an old screen to measure, do not despair! If other windows of your home have the same size window, then simply pop out one of those screens and measure it. If no other windows have screens to measure:

Step1: Find the lip and measure up.
The “Lip” of your window is what will hold your window screen in place. Place the end of the tape measure behind the lip and measure vertically up to the window screen channel. You will want to find the measurement and then add an 1/8 of an inch.

Step 2: Measure the horizontal screen channel.
When you measure the horizontal screen channel, you will want to find your measurement and then subtract an 1/8 of an inch.
