What is the diameter of a standard curtain rod? The most commonly sought-after sizes and styles feature a 1 and 3/8 inch (in diameter) size curtain rod to a 2-inch curtain rod, typically for windows with a length measuring between 66-120 inches.
What size curtain rod do I need for 72 inch window? A rod that is 48 to 84 inches in length will adequately fit a window up to 72 inches wide. This size is the most common window you will find in many homes.
How do curtain rod sizes work? For most drapery, you should allow approximately one-third of the width of the window for the stack-back. If the drapery fabric is unusually bulky, you may need to add an extra inch or two. Heavier fabrics and wider windows require more of a stack-back than lighter-weight fabrics on narrow windows.
How much wider Should curtain rod be than window? Additionally, be sure to choose a curtain rod that’s wider than your window. This allows curtains to be pulled completely to the side of the window and makes the space feel larger. The rod itself should be 8 to 12 inches longer than the window’s width, which allows for 4 to 6 inches on either side.
