Hello, yes these shades are available in custom sizes so we could cut a half inch off. We do recommend you ordering it the correct size and not cutting it yourself because this will void the warranty. Let us know if you plan to use for inside or outside mount. Inside mount comes with a 1/2-inch deduction made to the width, this is an industry standard
