If your window pole/rod is already in place, please measure the length of the pole/rod (not including the ﬁnals). We suggested to choosing 1.5-2 times of width you need to make your curtains have a wave effect.
If your window pole/rod is not in place, please measure the window from the outside of the trim to the outside of the trim from side to side. With (B) is your width.
We recommend extending hardware out from the edges of your window as much as 6"- 12" on each side when possible. And all headers have bulit-in 150% fullness alreadly. This will help make the area look larger, and will also allow as much natural light as possible when the drapery is open.
If your window pole/rod is already in place, please measure from the top of the rod.
There are 3 types of length to choose as the picture shows:
Sill Length: Just touches window sill
Apron Length: Falls 4-6 inches below window frame
Floor Length: Dusts the floor
If your window pole/rod is not already in place, measure above the window trim, at the point you intend to mount the rod. This is your length.We recommend mounting your rod a minimum of 4 to 6 inches above the window trim if space allows.
