Wall mounted rods are usually installed four inches above the window.
Where to place curtain rods above window.
Insert the back curtain rod if you re using a double rod setup.
To find your ideal placement measure down from the ceiling to the top of the trim at.
Ideal position for the curtain rod is 6 inches above the window trim but you may need to adjust this up or down so the curtains end where you want them.
This will allow whatever curtains you chose to cover the window at all times.
Step 3 next measure the window height.
Watch the rod width.
Use a level too especially if you live in an old house with less than perfect walls.
Your curtains may hang from the pole using a sleeve rings or eyelets.
If you re not using a double rod you can skip this step.
For example on a 54 inch wide window you could extend your curtain rods up to 9 inches on each side 54 divided by three equals 18 so your rod can be up to 72 inches long.
For cathedral ceilings leave approximately four to six inches above the window trim as a guideline.
Put the main curtain rod in place.
Go for a curtain rod that is between 8 and 12 inches wider than your window as it will give the illusion that your window is larger than it is.
No matter what the ceiling height the minimum distance from the top of the window casing to the curtain rod is two inches.
Then you can hang your sheer curtain or blackout curtain.
You may need to adjust the height of the pole for different curtain hanging styles.
Hang the curtains and double check to make sure your brackets are still secure.
The one above was made using a couple pieces of cardboard and saved time otherwise spent measuring from the corner of the windows.
Attach curtain rings if they are part of your setup.
When selecting the right curtain rod go for one that is a bit wider than the width of your window.
