There are three heights at which you can hang the heading of your curtain. These are at ceiling height, just above the window frame or flush with the window reveal. This choice should be based on the amount of space you have in your home, making it larger or adding warmth.
Therefore, for standard drapes that hang on either side of a window creating a frame, the typical height at which to install the drapery rod is halfway between the top of the window and the ceiling. This applies if there are more than 12 inches between the window trim and ceiling. For a cathedral ceiling, try to leave approximately 4 to 6 inches above the window trim as a guideline. If your ceiling is low, consider installing the rod as close to the ceiling or crown moulding as possible. In a small room, hanging drapery panels as high as possible will give the illusion of extra height.
