The front wipers are 26 inches on the driver side and 19 inches on the passenger side; the rear wiper is 11 inches. Always verify with your owner's manual or by checking your current blades before purchasing.
Front wiper blade sizes
The 2018 Odyssey typically uses two different sizes for the front swept area to maximize visibility from the driver’s seat.
Driver-side blade
26 inches
Passenger-side blade
19 inches
Note: Wiper performance can be affected by the curvature of the windshield and the mounting method. If you replace with a brand other than OEM, ensure compatibility with the wiper arm’s connector.
Rear wiper blade size
The rear wiper blade on the 2018 Odyssey is a single blade measuring 11 inches.
Rear blade
11 inches
Rear blades have a different mounting and connector than the front blades; check the adapter compatibility when shopping.
Tips for choosing wiper blades
When selecting blades, consider blade type, connector compatibility, and climate. The options below cover common considerations.
Blade type
Beam-style (also called flat) blades generally provide more even pressure and better performance across the windshield compared with conventional framed blades.
Connector type
Most Honda vehicles use a hook-style connector for the front blades, but some aftermarket options require adapters. Confirm the connector type on your wiper arms before purchase.
Climate and durability
Winter or all-weather blades with protective coatings or silicone wipers can last longer in extreme temperatures; consider seasonal replacements if you drive in freezing or hot climates.
How to confirm fit for your Odyssey
Always verify by consulting your owner's manual, checking the OEM part number, or using a retailer’s fit guide by year, make, and model. You can also measure your current blades (end-to-end length) and match to the replacement blades' size and connector type.
Summary
For a 2018 Honda Odyssey, plan front wiper blades at 26 inches (driver) and 19 inches (passenger), with an 11-inch rear blade. Confirm through the manual or a trusted parts retailer, and choose blades based on blade type, connector compatibility, and climate for best performance.
