How to Measure and Order Custom RV Shades for Perfect Fit

The reported 25-inch and 72-inch material widths are not confirmed order widths. Fabric width, complete shade width, window opening and inside-valance clearance are different measurements. The 49-inch and 36-inch window heights also do not by themselves establish drop from the chosen mounting point. Identify the shade style and manufacturer, mounting location, obstructions and the order form's measurement definitions before selecting finished dimensions.

Irvine's manufacturer measuring guidance uses different methods for different products. Its pleated-shade guide adds 2 inches total to measured window width and drop, and says the shade should be 1/2 inch narrower than the inside of the valance. This is not an instruction to add 2 inches to every side or to use fabric width as window width. For an identified Slow-Rise roller shade, the same support page instead starts with inside-valance width near the top, subtracts 1 inch, and measures drop from the inside top or mounting position to the bottom of the window frame. The roller-shade diagram shows those reference points. Do not transfer either method to an unidentified Valu-Line or other shade system.

With the measurements given, exact finished order dimensions remain unconfirmed; the earlier inside/outside-mount sizes should not be treated as approved specifications. Record the selected style, quantity, mounting position, confirmed finished width/drop and exact current fabric/color code for each window. A night shade and a day/night shade may require different fabric selections. Verify the actual available fabric and final specifications before ordering rather than assuming any color change, fit, return eligibility or replacement outcome is guaranteed.
