In most current Acura MDX models the driver-side wiper blade is 26 inches and the passenger-side blade is 18 inches. Older MDX generations used smaller combinations, such as 22 inches on the driver side and 19 inches on the passenger side. Always verify the exact sizes for your specific year and trim.
Wiper sizes by MDX generation
First generation MDX (2001–2006)
The following sizes were commonly used on the original MDX models. Use these as a baseline but confirm for your exact vehicle.
- Driver-side blade: 22 inches
- Passenger-side blade: 19 inches
These sizes reflect the typical setup for early MDX models before later redesigns standardized larger blades.
Second generation MDX (2007–2013)
As the MDX grew in size and market expectations shifted, blade lengths changed to accommodate wider windshields.
- Driver-side blade: 26 inches
- Passenger-side blade: 18 inches
This generation commonly used a 26/18 inch pairing, though some late-year variations can occur depending on trim and regional specs.
Third generation MDX (2014–2020)
With the 2014 redesign, many MDX models settled on a standard large-driver configuration paired with a mid-size passenger blade.
- Driver-side blade: 26 inches
- Passenger-side blade: 18 inches
Most 2014–2020 MDX vehicles align with the 26/18 inch pattern, providing consistent coverage across models.
Fourth generation MDX (2022–present)
The latest generation generally follows the established large-driver format while keeping the passenger blade compact enough for good visibility.
- Driver-side blade: 26 inches
- Passenger-side blade: 18 inches
Current MDX models typically use a 26/18 inch pairing, though regional variations or trims may exist. Checking the owner’s manual or current blade packaging is recommended.
How to confirm the exact size for your MDX
To ensure you buy the correct blades for your specific MDX, use these steps:
- Consult the owner's manual or the current blade packaging for the exact lengths.
- Measure the existing blades end-to-end if you don’t have the manual handy.
- Enter your vehicle’s year, make, and model into an auto parts retailer’s lookup tool to see matched sizes.
Once you have the correct sizes, consider the blade type (standard, hybrid, or silicone) and any regional weather considerations to maximize performance.
Summary
Across its generations, the Acura MDX generally uses a 26-inch driver-side wiper and an 18-inch passenger-side wiper for modern models, while older generations used smaller combinations such as 22/19 inches. Always verify the exact sizes for your year and trim to ensure proper fit and optimal visibility.
