Most 2018 Ford F-150s use 20-inch front wiper blades on both sides, with an 11-inch rear blade if the truck is equipped with a rear window wiper. Exact sizes can vary by cab configuration and trim, so it's best to confirm using the owner's manual or by comparing to the blade currently installed.
Front wiper blades
The front blades on most 2018 F-150s are 20 inches long on both the driver and passenger sides. Some specials or aftermarket setups may use different lengths, but 20 inches is the standard for factory-equipment blades.
- Driver-side front blade: 20 inches
- Passenger-side front blade: 20 inches
These sizes cover the majority of 2018 F-150 pickups. If your truck has a non-standard configuration, verify by measurement or the owner's manual.
Rear wiper blade (if equipped)
Not every 2018 F-150 has a rear window wiper. If yours does, the rear blade is typically 11 inches long.
- Rear wiper blade: 11 inches
If your vehicle does not have a rear wiper, you can ignore this size entry.
How to confirm your exact size
If you want to be sure you buy the correct blades, use one of these verification methods before purchasing:
- Consult the owner's manual for blade size specifications for your trim and cab configuration.
- Measure the blade currently installed by removing it and measuring its length with a ruler or tape.
- Use an auto parts retailer's lookup tool by entering your vehicle's year, make, model, and cab (e.g., 2018 Ford F-150 SuperCrew) to confirm the recommended blade sizes.
Verification ensures you get the right sizes for your exact truck, and helps avoid mismatched or ill-fitting blades.
Summary
For most 2018 Ford F-150 pickups, you should use 20-inch front wiper blades on both sides and, if equipped, an 11-inch rear blade. Always verify against the owner’s manual or an official parts lookup for your specific cab configuration to ensure the correct fit.
