Front wipers are typically 26 inches on the driver’s side and 18 inches on the passenger’s side. If your RDX has a rear wiper, the rear blade is usually 11 inches. Always verify with your owner's manual or a parts diagram for your exact vehicle configuration.
Front wiper blade sizes
The following list outlines the standard front wiper blade lengths for the 2020 Acura RDX. These sizes are commonly used by OEM and aftermarket suppliers.
- Driver-side blade length: 26 inches
- Passenger-side blade length: 18 inches
When shopping for replacements, ensure you select 26" and 18" blades for the driver and passenger sides, respectively. Some aftermarket offerings may vary in packaging but typically match these lengths.
Rear wiper blade size
Not all 2020 RDX models include a rear wiper, but if yours does, the standard rear blade length is typically 11 inches. The exact size can vary with trim or tailgate design, so confirm before purchasing.
- Rear blade length (if equipped): 11 inches
If you’re unsure whether your vehicle has a rear wiper, consult the owner’s manual or check your current blade for length as a quick reference.
How to confirm the correct size for your vehicle
Use one of these verification methods: check the owner’s manual, inspect the blade packaging or label on the blade itself, measure the blade length from the center of the metal frame to the tip, or use an OEM parts finder with your VIN to pull the exact part numbers.
Tips for choosing blades
Consider beam-style blades for better contact over the curved windshield, and opt for silicone or treated blades if you drive in extreme weather. Replace blades as a pair when possible to maintain even wear and consistent performance, and ensure you have the correct adapters if switching brands.
Summary
For a 2020 Acura RDX, plan on front wipers of 26 inches on the driver’s side and 18 inches on the passenger side, with an 11-inch rear blade if your model includes a rear wiper. Always verify the exact sizes using your manual or a credible parts finder, as trims and production changes can alter specifications. Properly sized blades ensure clearer visibility and safer driving in all conditions.
