The 2020 Honda Odyssey uses two different front-wiper lengths: 26 inches on the driver’s side and 18 inches on the passenger’s side, with an 11-inch rear blade. These sizes are the standard factory specs and are commonly used for replacement blades across most trims.
Wiper blade sizes can vary if aftermarket parts are installed or if certain trim configurations require different connectors. This article outlines the official sizes and how to verify them before you buy blades.
Front wiper sizes
The following list shows the standard front wiper sizes for the 2020 Odyssey, separated by driver and passenger sides.
- Driver's side: 26 inches
- Passenger's side: 18 inches
When replacing, you can choose to replace both blades at once to ensure even wiping performance. If you're unsure, check the length stamped on the blade itself or refer to your owner's manual for confirmation.
Rear wiper size
The rear window uses a single wiper blade, typically sized at 11 inches.
- Rear blade: 11 inches
Be aware that rear blade connectors and mounting styles can vary; confirm compatibility with your vehicle’s rear wiper arm before purchasing.
Blade type considerations
Wiper blades come in several styles, including conventional framed blades and modern beam blades. Both are available for the Odyssey; the choice often comes down to climate, noise preferences, and budget. Ensure you select the correct lengths (26" and 18" for the front, 11" for the rear) and the proper connector type for your wiper arms.
Summary
For a 2020 Honda Odyssey, the standard front wipers are 26 inches on the driver's side and 18 inches on the passenger's side, with an 11-inch rear blade. Always verify sizes before purchasing—check the blade markings, the owner's manual, or the OEM parts diagram for your specific vehicle configuration. Replacing both front blades together is recommended for optimal visibility and even wear, while the rear blade should be matched to a single 11-inch size.
