The standard front wiper blade lengths for the 2020 Toyota Tundra are 26 inches on the driver’s side and 18 inches on the passenger side. If your truck has a rear window wiper, the rear blade is typically 12 inches.
For more detailed guidance, blade lengths can vary by market, trim, or aftermarket replacements. Replacing the front wipers in matched pairs helps ensure even wear and consistent performance. The rear wiper, when present, is a shorter blade and is less commonly replaced unless required by a specific model configuration.
Front wiper blades
Front blades come in two different lengths to follow the curvature and coverage of each side. Use the sizes listed below when shopping for OEM or aftermarket replacements.
- Driver-side blade: 26 inches
- Passenger-side blade: 18 inches
Replacing both front blades in a paired set is recommended to maintain balanced wiping across the windshield and to optimize performance in rain, snow, or mist.
How to verify and replace front blades
To confirm the exact size for your truck, check the owner's manual, the blade packaging, or the part numbers in a local parts diagram. When replacing, choose a 26" driver-side and an 18" passenger-side blade compatible with your wiper arm style (hook, pin, or side-molded adapter).
Rear window wiper (if equipped)
Not all 2020 Tundra trims include a rear window wiper. If yours does, the rear blade is smaller than the front and is typically around 12 inches in length.
- Rear blade: 12 inches
As with the front blades, verify the rear blade size by checking the owner’s manual or the blade packaging to ensure a proper fit for your specific model and wiper arm configuration.
Summary
The 2020 Tundra uses 26-inch driver-side and 18-inch passenger-side front wipers, with a possible 12-inch rear blade if your model is equipped with a rear wiper. Always confirm sizes on your specific vehicle via the manual or a reliable parts diagram, and replace blades in matched pairs for best results.
