Learn how to measure window screens. The DIY way to accurately get screen measurements for windows.

If your existing window screens have at least one side of the width and of the height not bent. Then you can easily measure your replacement screen by measuring the existing window screen.

Measure and write down the width by length.  Verify which type of window you have and determine the thickness of screen frame you need.

Determine if you need tension springs and or pull tabs. Also determine if you need them installed on the side or top / bottom.  Pull tabs generally go on the opposite side of the springs. Some window screen have only pull tabs and no tension springs.

Most noteworthy, keep note that in many homes the window screens sizes will vary from window to window

Steve also explains the challenges people can face when measuring and ordering window screens. A lot of time when you have these window screens and you measure them, you know you might measure it and sometimes it may not fit. You may have to trim it down.

Be advised when you are with measuring window screens not everyone is an expert even the experts. Therefore you will need a chop saw or a hack saw to trim your frames and also the rolling tool to rescreen the screening back into the frame. If you are planning on doing window screens yourself, make sure that you have those tools available and you can do that. Don’t expect to order a window screen and have it fit all the time. Just because if you measure you measure correctly, for some reason, sometimes they just don’t fit.
