Measure the same way as you do for other blinds, but keep the following in mind: Chain Lift: Distance from edge of window to fabric on inside/outside mount: 7/8” on chain side, 3/8” on opposite side for a total of 1 ¼”. Spring Lift: Distance from edge of window to fabric on inside/outside mount: ~7/8” on each side for a total of 1 ¾”. Finished product on all inside/outside mount Roller Shades & Solar Shades will be made to your size specifications and will be tip to tip. For shades with chain lifts, the actual fabric width will be 1 ¼” less than the total measurement for inside/outside mount, and for spring lifts, the actual fabric width will be 1 ¾“ less for inside/outside mount.
We recommend adding to the width of your outside mount shades to ensure maximum coverage. For example: If you are ordering an outside mount shade with a chain lift at 64” wide x 60” high and want the actual fabric width to be 64”, then you need to order a size of 65 ¼” wide x 60” high.
