Curtain rods are generally mounted on the wall above and outside the window molding to allow the curtain or drapery to fabric to fall gracefully. If you have a detailed window frame that you prefer not to cover, you can consider an inside mount, where you hang the curtains within the frame. The brackets should be installed to extend far enough from the wall to clear both the window frame and any blinds that are hanging on the window. First, you measure the width of your window, taking into account whether they’ll be inside mounted, trim mounted, or wall mounted. Of course, if you are using a special style rod such as a double or blackout, you will want to follow the manufacturer’s mounting instructions for specifics. A few tips to keep in mind: Allow 3 to 9 inches on either side of the window frame for the panels to rest comfortably when they are open and also take into consideration any extra wall space that will be needed for decorative finials.
