• To guarantee the best fit for your window, use the following steps:
• Inside Mount: Measure the precise dimensions of your window. For instance, if the window is 23" by 72", subtract 0.25-0.5 inches from the width for the blinds, without altering the height.
• Outside Mount: Increase the width and height by at least 4" for better coverage. In this case, the blinds should be 27" wide and 76" long.
• Fabric will be 0.8" less in width than the total shade width for either type of mounting.
