Inside mount window treatments are installed inside the window frame or casing – they provide a sleek, clean look which can showcase your window size and moldings. If you’re interested in measuring for inside mount blinds, follow these steps:

• 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 1/2“ 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.

Outside mount window treatments are mounted on the window molding, wall, or ceiling above your window. Outside mount blinds or shades can make your windows appear wider and longer while also providing better light control and privacy options. You may be required to install an outside mount if your windows do not have sufficient mounting depth.

Follow these simple steps to measure your windows for an outside mount window treatment:

• Measure the exact width of area to be covered. Be certain the measurement overlaps the window opening by at least 1 1/2” on each side to ensure privacy and light control.
• Measure exact height to be covered, including desired overlap (usually from top edge of molding to bottom edge, or to top of sill). If there is no sill, measure to where the blind is to reach.
• The factory does not make deductions for an outside mount.
