Measuring Instructions
How to Measure for Blinds and Shades
(It's simple!)


General Information

  • Use a steel measuring tape and measure down to the nearest 1/8".
  • Don't be surprised if your windows aren't perfectly square.
  • Measure all windows, even if they appear to be the same size.
  • Decide if you want your blinds installed within the window opening (Inside Mount) or on your wall/trim (Outside Mount). Most people use an Inside Mount for a neater look, but make sure you have enough depth to allow the product to fit. Use an Outside Mount when your opening is too shallow or when your window is significantly out of square.

 Measuring for INSIDE MOUNT: 
Provide the EXACT window opening size. DO NOT TAKE ANY DEDUCTIONS. The factory will deduct approximately 3/8" to 1/2" from the width you designate so your product will not rub against the sides of your window.

Measure in 3 places (top, middle, and bottom) and use the NARROWEST measurement.

Measure in 3 places and use the TALLEST measurement, EXCEPT for privacy sheer blinds (use the shortest measurement).


 Measuring for OUTSIDE MOUNT: 
Specify the EXACT WIDTH and the EXACT HEIGHT you want your product; the factory will make your product the exact size you specify. Include in your measurement room for the mounting brackets, which are up to 2-1/2" tall. Also consider adding a few inches on the sides, top, and bottom for additional privacy as well as to block more light. Be alert of any obstructions like a deadbolt or door knob.
