If you are planning a window treatment for your large or extra-large window, you might be wondering “What is the maximum width of blinds and shades for windows?” The maximum width depends on the type of blind or shade that you are going to choose for your windows. For example, if you choose Day and Night Blackout Cordless Cellular Shades, they may have the maximum width of up to 72 inches. On the other hand, Sheer Horizontal Room Darkening Shades may measure up to 96 inches wide. In the case of Essential 1 Inch Cordless Privacy Mini Blinds, the width options vary from 18 to 72 inches. However, you always have the option to choose a custom size for each of these products. What Width Should You Choose for Blinds and Shades? The width of your window blinds and shades would vary greatly, depending on the size and shape of the window frame. Some types of blinds, like Sheer Light Filtering Blinds and Shades Zebra Elegance, can be made in size ranging from 12 to 94 inches wide. Note: For maximum insulation and privacy, you need to add a few inches to width along each side. For example, if your window frame measures 90 inches, you should choose a 94 inches wide covering, which will add 2 inches to each left and right sides. How to Cover Extra-Wide Windows However, for extra-wide windows, you need to use multiple blinds and shades. Or you may consider a different type of window treatment. Some options for covering very wide windows include panel track blinds, drapes, and shutters. It’s a good idea to measure your windows carefully and precisely. You also need to consider your specific needs and preferences when choosing window treatments. How to Measure the Width of Blinds and Shades Measurement To measure the width of your window blinds or shades, you will need a steel measuring tape, a pencil, and a piece of paper, and follow these steps: Measuring Width for an Inside Mount: If you want to mount the blinds or shades inside of your window’s frame, measure the width from the inside of the frame at the top, middle, and bottom. Record the smallest of the three measurement values as your actual width. Measuring Width for an Outside Mount: If you want to mount the blinds and shades outside the window frame, measure the width of the area that you want to cover. Add 2-3 inches to each side (left and right) of the area to ensure proper coverage, privacy, and light control. Round the Value to the Nearest 1/8 Inch: Round your width measurement value to the nearest 1/8 inch. For example, if your measurement is 35 3/4 inches, round it up to 35 7/8 inches. Record the Width: Write down on a piece of paper the final width measurement of the window frame you have obtained. However, you should double-check your measurements to ensure accuracy before ordering your blinds or shades for windows. Note: Do keep in mind that different types of window blinds and shades have specific measurement requirements. So, make sure to follow the manufacturer’s instructions.
