Before you start measuring, decide where above your window opening you want to mount your shade. You will need at least 1" of flat vertical space above the window to mount the brackets. The shade can be installed directly above the window opening, or higher up to give the appearance of a larger window and to have more clear space in the window when the shade is raised.
If you have trim around the window, you can mount the shade above the trim, directly on the trim (if you have the required minimum flat space for the brackets), or to the sides of the trim if you do not have enough mounting space above the window or on the trim itself. See the directions below for how you'd like to install your shade.
If you do not have sufficient vertical space for mounting the brackets, please see our inside mount instructions or consider a different product.
