Ordering the correct panel sizes for your windows couldn't be easier. First, let's start with the height. We offer four basic sizes. We have a seven-foot, eight-nine and ten-foot panel. Now you're going to see this in inches, an 84, a 96, a 108, and a 120. First thing you do is get yourself a nice one-inch wide steel tape measure. They're easy to use and you get an accurate reading. I like to start from the floor and measure up. Now this window is just about 97 inches. So that's a little over eight feet. I would order a nine-foot panel. If you have a nine-foot window, order a ten-foot panel. That way you have a lot of leeway. When the drapery comes, you can determine how high you're going to hang that depending on what kind of break you want on the floor. You can watch our video on how to hang draperies later. The second part is determining the width. There are two components. Measure the width of the window. This one happens to be 40. Add a little bit to each side. I like to go four or six inches, something like that. Four to six on this side. 40 plus your six and six, 52. That's your rod length. Now here's the rule. For approximately every 50 inches of rod length, order two panels. So two panels will cover this window. You'll have one on this side and one on that side and it can even open and close. But what if your window is larger? What do you do? If you just want a decorative look, one panel on each side will do it. There'll be a lot of glass in between, but the window will look decorated. But what if you want the drapery to open and close? Here's what you do. Measure the full width of the window. Add your six inches on each side. That together is your rod length. Suppose that's a hundred inches. Use the rule. Every 50 inches of rod, two panels. Hundred inches, four panels. Or you could order two double panels. The double panels are a hundred inches each. So you could have two, one hundred inch double panels or four 50 inch panels. This will give you some fullness. So when you close the drapery, it's not just flat. It has some fullness to it. Follow these rules and your draperies will look great every time.
