Guidelines For A Perfect Fit

• Measure each window individually, as size variances are common.
• Record width first, then height (also referred to as length) to the nearest 1⁄8".
• Measure width from left to right, height from top to bottom, using a steel tape measure. Do not use a cloth tape.

Select your window fashion type for measuring instructions:

Horizontal Blinds and Fabric Shades, including Innovative Shadings and Solar Shades

Inside mount:

• Inside mount blinds and shades are installed inside the window casing. Minimum depth requirements vary by product and headrail type, or by tube size (for solar shades). Ask your designer or sales associate for details.
• Measure the exact inside width of window casing from one inside edge to the other in three different places. Record the narrowest measurement.
• Measure the exact height in three different places from top edge of opening to top of sill. Record the longest measurement.
• Do not take any deductions for clearance. The factory will take necessary deductions for a perfect fit.
• Measure the window diagonally in two places, as shown. If the two diagonal dimensions are not equal, we recommend an outside mount application for optimal shade function and aesthetics.
• Note on Solar Shades: On Continuous Loop inside mounts, there is a 7⁄8" light gap per side. On Cordless inside mounts, there is approximately 1 9⁄16" total light gap (31⁄32" on control end, 19⁄32" on idle end). For optimal light and glare control, outside mount is recommended.

Outside Mount:

• Outside mount blinds and shades are installed outside the window casing, covering an area larger than the window itself.
• Measure the exact width to be covered. Be sure the measurement overlaps the window opening by at least 1 1⁄2" on each side (3" total overlap) to ensure light control and privacy.
• Measure exact height to be covered, including desired overlap (typically from top edge of molding to bottom edge, or to top of sill if there is one).
• The factory makes NO allowances on outside mount.
