Measure the glass, not the frame
Measure the visible glass of each pane: width and height in inches, inside the frame or beading. If a window has two sashes, like most double-hung windows, measure each sash's glass separately.
Turn it into square feet
Width × height ÷ 144 = square feet for one pane. Add up every pane you want filmed. Or use the calculator below and send the total with your estimate request.
