Before you start measuring, decide where above your window opening you want to mount your blind. You will need at least 1 3/4" of flat vertical space above the window to mount the brackets. The blind 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 blind is raised.
If you have trim around the window, you can mount the blind 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 enough mounting space above the window or on the trim itself. See the directions below for how you'd like to install your blind.
If you do not have sufficient vertical space for mounting the brackets, please see our inside mount instructions or consider a different product.
