Measure the height of existing window. Take your measurements from the window sill to the head jamb. Look at the top of the window, and detect that at that place's another stop that runs horizontally. Information technology's a bit lower than the head jamb, or the very top of the frame. Measure out from the sill to the head jamb on the left, middle, and right sides, and use the smallest number every bit your true measurement.^[four]
- With the window open up, look at the bottom of the frame. The sill is where the sash sits. Don't misfile it with the stool, or the molding on the inside of the window that gives it a finished look. The stool is higher than the sill and, similar the stops, would throw off your measurements.
