How To Measure Aluminum Windows For Screens. Measure window screens ‘width’ (for windows with screen channel) put the end of a metal measuring tape from left to right and hold it as straight as possible. We arrange a visit from our trained technicians to provide advice and take measurements of.
Take a small tape measure to get the window screen measurement. To find the height, measure from the sill to the inside of the trim at the top of the window. Record this number as the width.
Run a metal tape measure from side to side in three places:

If the top or bottom edges of the window frame are slanted to allow water to drain, take the measurement at the narrowest point of the window. Measure it from there to the edge of the other side. This will be your recorded height which includes the lip size.
