Formula

## How to Measure Curtains Curtain length depends on window height, how high above the window you mount the rod, and the desired hanging style. ### Formula **Panel Length = Window Height + Mount Above + Style Extra** **Rod Width = Window Width + 6 inches on each side (12 total)** For fullness, total fabric width should be 2-2.5 times the window width.

48-inch wide window, 60-inch to sill, rod mounted 4 inches above, floor-length curtains.
