Standard lengths

How to measure
- Decide where the rod goes: at least 4 to 6 inches above the frame.
- Measure from the top of the rod to the floor.
- Take off half an inch for curtains that float just above the floor, add about 1 inch to just touch it, or 6 to 8 inches to puddle.
- Check how the curtain hangs: rings, grommets and tabs change where the fabric starts.
