Tape Measure Troubleshooting Guide
My measurements weren’t accepted. What now?
Use a metal tape measure. Fabric tape measures can stretch and give inaccurate measurements.
Use the same tape measure to record all measurements.
Keep the tape measure taut across all measurements.
Compare the measurements entered into your Measure by Indow portal to those written on the Measure Form to verify there are no errors.
Review your width (A & B) and height (C & D) measurements. Typically, the left and right heights (C & D) are within ½” of each other even if the window frame is out of square. It is unusual to see a left height of 35” and a right height of 36” on the same window. The same is true for the top and bottom widths (A & B).
Make sure the “Tape Measure” checkbox is checked.
Once you’ve taken these steps, if the measurements still aren’t accepted, schedule a Measure Support call.
Request Your Measure By Indow Portal
You need to provide your measurement details through Measure by Indow. A link to the self measure form should have been provided in the first email after your order was confirmed. If you can’t find it, don’t panic! Let us know and we can help with your measurements, self measure kits (laser measure kit), consultation to measurement, or anything you need.
