* Checking your owner's manual: This is the most reliable source.
* Looking at the existing wipers: The size should be printed on the wiper arm or the wiper blade itself.
* Using an online wiper size finder: Many websites allow you to input your vehicle's year, make, and model to determine the correct wiper size. Be sure to use a reputable site.
Don't rely solely on this information. Always double-check before purchasing new wipers. Slight variations can exist depending on trim level or regional specifications.
