Window curtain measurement diagram with width length and drop annotations

How to measure your window for curtains

Width: Measure the curtain rod, then add 6 inches on each side for fullness.

Length: Measure from the rod down to the floor, sill, or wherever you want the panel to break.

Drop: For a tailored look, hem at floor + 0 to 1 inch. For a puddle finish, add 2 inches.
