What You'll Need

  • Metal tape measureMore accurate than cloth tape
  • Pen or pencilTo note each measurement
  • PaperOr the notes app on your phone

Before you measure

  • Use a metal tape measure

    Cloth and plastic tapes stretch, so the numbers can be off.

  • Measure to the nearest 1/8"

    Write down the exact number. If you have to round, round down.

  • Check the window depth

    Inside mounts need a minimum depth for the brackets. Each guide lists it.

  • Don't make deductions

    Give us the actual size of the opening. We adjust the shade so it fits and moves freely.
