Is there a tutorial to learn how to measure window blinds?

As of 2015, a tutorial that shows how to measure window blinds is available at InteriorDecorExperts.com. This tutorial provides instructions for taking measurements for both inner and outer mount blinds.

Inner mount blinds mount to the inside of a window, leaving the bracket hidden and requiring no extra work to cover it. Outer mount blinds mount to the wall or to the sill on the outside of the window. These types of blinds often hang vertically on long doors and windows. In many cases, a wooden valance covered in fabric that coordinates with the decor of the room hides the bracket.
