Where Should I Hang My Drapery Rod?
If there are 12 inches or more between the top of your window molding and the ceiling or crown molding, hang the drapery rod at the halfway point.
If there are less than 12 inches between the window molding and ceiling or crown molding, hang the drapery rod directly below the ceiling or crown molding. This will help make the ceiling look higher.
If your ceiling is low, regardless of the space between the window molding and ceiling, hang the rod right at the ceiling. This, coupled with the vertical line of the drapery, will make the ceiling look higher.
If your window moldings are pretty, don’t cover them up — make them the focal point. Hang the rod at the very bottom of the molding, or even just below the molding at the top of the window frame.
