For cathedral ceilings leave approximately four to six inches above the window trim as a guideline.
Curtain rod above window trim.
The higher the rod the closer to god 2 extend your curtain rod so that it s at least 7 10 past the edge of the window.
When you hang the curtain rod high it will make the window appear taller.
No matter what the ceiling height the minimum distance from the top of the window casing to the curtain rod is two inches.
Hanging curtain rods high above the window frame adds height to the wall and works best with long panels or drapes.
Wall mounted rods are usually installed four inches above the window.
If that s the case i recommend hanging the rod about two feet above the window.
When installing curtain rods hang the rod so that it extends at least 3 or 4 inches beyond the window on each side which allows your curtains to overlap both the window and the wall to prevent light from leaking in around the window s edges.
Standard curtain rod placement 1 measure 2 inches to the right and left of the top corners of the window frame trim.
The precise placement of yours depends on a few factors ceiling height curtain length trim molding style etc so i can t give you a hard and fast measurement for where your rod should always go but generally we like to hang ours about 3 4 below the ceiling or if there s crown molding 3 4 below the bottom edge of the crown.
In general windows with plenty of wall space on either side can afford a longer rod and larger finials.
Your curtains may hang from the pole using a sleeve rings or eyelets.
Don t scrimp on length.
But for the rest of us.
Mark with chalk or a pencil.
See in the photo below how the rod keeps going well past where the window stops.
To find your ideal placement measure down from the ceiling to the top of the trim at the left corner of your window.
A rule of thumb from architectural digest is that curtains should be hung between 4 to 6 inches above the window frame so install your curtain rod accordingly.
This applies if there are more than 12 inches between the window trim and ceiling.
