To find the right wiper blades for your car, you need to know the correct size. The correct wiper blade size depends on your vehicles year, make, and model. You can find the sizing information in your owner's manual or by using a blade size finder tool. Rain-X offers a blade size finder on its website where you can search based on the year, make, and model of your automobile. Other wiper blade manufacturers like TRICO® also offer similar tools. If you're unsure of what blade size you need, you can also try searching for your vehicle blade size online. Once you find the correct measurements, you can purchase vehicle-specific blades or find general blades that match the length required for certain automobiles. There are different types of wiper blades, including conventional blades, beam blades, and hybrid blades. All three types work with all vehicles, and there is no right choice.
