Measurement tips:
For inside mount, provide exact window opening’s height and width. There will be visible light gaps of approximately 5/8″ on each side. Inside mounted cassette or valance shades will receive a 1/8″ deduction on width to allow hardware to fit properly.
For outside mount shades, provide the exact size of the shade, not the opening of the window. The fabric is 1 1/4″ narrower overall than the size of the ordered size. We suggest adding at least 2″ to the width and 3″ to the height of the opening for proper coverage.
