How to Find the Size of Your Window Wiper Blades

Consult your vehicle's owner's manual: It will tell you the length, in inches, of each of your vehicle's wiper blades. Skip to the next step if you don't have the vehicle's owner's manual.

Measure the wiper blades with the measuring tape. Since wiper blades are measured in inches, make sure you measurements are taken in inches. Measure each of the blades, as many vehicles use two wiper blades of different lengths.

Find your vehicle on the Rain-X Wiper Blade website, listed as a Reference below. Vehicles are sorted by manufacturer. Once you locate your specific vehicle, you will not only be provided with the length of each of the wiper blades, but also with the specific design of the wiper blades.
