Measure the Window
Take accurate measurements of the window on which the rod will be mounted. Measure the length of the window as well as the width. Curtains come in a variety of lengths, so the rod must be hung at the correct height for the curtain length used.
Mount the Brackets
Most curtain rod sets come with the hardware needed to mount the brackets to the wall. Use the right type of wall anchor for the type of wall in your home. The weight of the curtains that will hang on the rod are also a consideration.
Secure the Rod
Most brackets that come with curtain rods contain a small screw that is used to secure the rod in place. Tighten these screws against the rod to ensure the rod doesn't slide back and forth in the brackets.
