|Inside mount blinds are installed inside the window frame.
- Measure the exact inside width of window frame from one inside edge to the other. Take three measurements, one near the top, one in the center and one near the bottom. Record the narrowest measurement.
- Measure the exact height in three places, left, center and right from top edge of opening to top of sill. Record the longest measurement for horizontal blinds.
- Do not take deductions on inside mount measurements. The factory will take an 3/8“ allowances for operating clearance.
- Measure the window diagonally in two places as shown. If the two diagonal measurements are not the same, we suggest an outside mount application for the best shade performance and appearance.
