How to confirm the correct sizes for your car
Before buying blades, you can check several reliable methods to confirm the exact sizes for your vehicle:
- Consult the owner’s manual or a stamped blade size label on the current blades
- Check a parts retailer’s listing for your exact year, make, and model
- Measure the existing blades: use a flexible tape and follow the curvature along the blade edge
If in doubt, many auto parts stores will verify sizes in person and can install aftermarket blades to fit your car.
Alternative confirmation methods
Use your vehicle’s VIN when ordering, consult the owner’s manual, or check the original blade packaging for size stamps to ensure an exact match.

For the 2018 Nissan Altima, plan for 26" driver-side front blades and 17" passenger-side front blades, with an 11" rear blade if your car has one. Always verify sizes using the owner’s manual, current blades, or retailer listings, as regional variations and trim differences can occur.
