How to Measure

Step 1

MEASURE THE INSIDE WIDTH of the opening width at the top, middle, and bottom of window opening. Use the narrowest measurement when ordering.

ROLLER SHADES Measure the exact width of the opening where the roller shade will be installed, to the nearest, lowest 1/8".

Step 2

MEASURE HEIGHT of opening on left, center, and right. In most cases, you will use the largest measurement when ordering.

Wall-to-wall or ceiling-to-floor measurements should be treated as an inside mount measurement.

Extra Step

MEASURE THE WINDOW ON THE DIAGONAL. If the two diagonal dimensions are not exactly the same, it may be more appropriate to specify an outside mount shade for optimal light control and privacy. Outside mount is recommended for windows greater than 1/2" out of square. Measure the top of the window opening front to back to verify depth variances.

PLEASE NOTE: Inside mount measurements represent the exact window opening, do not add or subtract from your measurements. The factory will make the necessary deductions to ensure a proper fit.

MINIMUM DEPTH: You will need this much unobstructed depth, including cranks, handles, locks, etc., to inside mount the window treatment. Depth requirements for all products can be found on pages 8-10 of the Spec Guide.

FLUSH MOUNT: For the face of your treatment to be flush with the wall or window frame, your frame depth must be the same or greater than the Flush Mount depth required.

Step 1

MEASURE THE WIDTH of the area you wish to cover. Measure across the top, center and bottom of the window. Use the largest measurement when ordering. We recommend adding overlap to reduce light leakage around the blind. 

ROLLER SHADES Finished roller shade sizes are based on tip-to-tip measurements. When ordering an outside mount shade, determine the width you desire the fabric to be and add for the tip-totip measurement. See Roller and Solar Shades section for additional information. 

Step 2

Decide if the headrail will be installed on or above the window molding. You will need a flat surface area. Measure the height of the area you wish to cover and provide exact dimensions.

PLEASE NOTE: Outside Mount (OM) measurements represent the exact blind size needed. No allowances will be made by the factory. 

MINIMUM MOUNTING SURFACE: You will need this much unobstructed flat space to outside mount the window treatment. OM flat mounting surface requirements can be found on pages.
