Remember, she determined that the rod will be hung 104 inches from the floor. She subtracts 2 inches that the drapery rings will occupy below the rod and adds a modest 3-inch puddle, so her draperies need to be 103 inches long (104 – 2 + 3). To summarize: The window is 54 inches wide, including the window frame. The rod is 102 inches wide total.
