Bayonet. Most replacement blades include an adapter for it, so check the adapter chart in the package.

Can I use a wiper blade one size longer or shorter?

Stick with the listed sizes. A longer blade can hit the windshield frame or the other blade, while a shorter one leaves an unwiped gap. If your old blades don’t match our sizes, measure them end to end.

How often should I replace my wiper blades?

Most drivers change them every 6 to 12 months. Swap them sooner if they start to streak, chatter, or miss spots.
