Is Your Window a Square?

Before deciding on which mount you will use, measure your window to be sure it is square. Measure diagonally from the two top corners to the two bottom corners. If the two measurements are significantly different, the window is off-kilter and you should choose the Wall Mount.

Time to Measure

Once you have chosen the mounting option that works best for your window, it's time to measure your windows to determine hardware length. Keep in mind that if you have chosen the Wall Mount option, you will need to add 6 inches to the length of your rods. Also, depending on what style you choose, finials can add up to 4 inches on each end of the rod, so you want to make sure there is enough clearance to allow for your finials.

The Layered Look

To create a layered window treatment, you will need hardware that can accommodate two panels. Our Double Add-On Kit comes in all the same sizes and finishes as our rods.

Guide to Window Panels

Choose Your Look

Curtains should always be long enough to reach the windowsill, but how much farther they extend is a personal decision. There are two options for displaying your window treatments: to the sill (or just below the sill) and to the floor. For deeply recessed windows, you'll want the window panel to be at sill length, or just below. If the width of your mounting measurement is less than 88", we recommend at least two panels. If your measurement exceeds 88", additional panels will be required for total coverage.

Roman Shades

If you are installing a Roman shade, remember that the mounting rod is 1 3/8" wider than the fabric. When measuring, add 1 3/8" to overall width of shade to ensure it will fit inside the window frame. For example, a 22" roller shade measures 23 3/8" with mounting hardware.

Important Safety Tips

Do not place cribs within 18 inches of curtain panels, curtain pulls or curtain cords. Keeping cribs away from windows is your best option to ensure safety.
