Vinyl Attention: How to Measure for Inside Mount: The blind you order will be the exact size with no deductions. To ensure a proper fit, measure the width of your window at the top, middle, and bottom. For a 32.5" wide blind, your window should measure between 32.75" to 33.5" wide, allowing for a snug fit with minimal light gaps. Next, measure the height from the top of the window to the windowsill on the left, middle, and right sides, and use the largest height measurement when placing your order.
