Measuring for Vertical or Soft Sheer Verticals

Inside Mount Width
•    Measure the exact width (left to right) of the inside edge of the window frame in three places (top, middle and bottom).
•    Take the smallest of the three measurements to the nearest 1/8 of an inch.
•    The factory will make the correct deduction from the total width to allow for proper installation.  Most manufacturers’ deduct 1/4” from the total width.

Inside Mount Height
•    Measure the exact height (top to bottom) from the top inside edge down to the window sill in three spots across window.
•    Take the smallest of the three measurements.

Outside Mount Width
•    Measure the exact width (left to right) of the wooden or metal window frame (outer edge) OR how wide you want the product to be.
•    For verticals make sure the measurement overlaps the window opening by at least 3" on each side to ensure light control and privacy.
If you want the entire window uncovered when the shade is fully open, you may need to add more than 3" to the width on each side.
Determine if the head rail will be on the molding or above and mark the spot.

Outside Mount Height
•    Measure the top and bottom edge of window frame/trim. If no trim, be sure you provide the height you want the shade to be from top of the head rail to bottom of your desired height.
•    Be sure to allow for coverage for light control and mounting hardware if mounting above window opening to wall surface. You will need 2 inches of surface area to mount above opening.
Measure height to be covered from top of head rail location to top of sill or lower if overlap is desired for light control and privacy. Record measurement, if shade extends to the floor (i.e. to cover a patio door), measure height as described above, and deduct at least ½" for clearance in order for the fabric to clear the floor. Note: The manufacturer makes NO deductions on outside-mount installations.
