The driver-side blade is 26 inches and the passenger-side blade is 20 inches for most 2020 Subaru Outback models.
This guide explains the standard sizes, how to verify fit, and the best replacement options, including blade types and reputable brands.
Standard blade sizes for the 2020 Outback
These sizes cover the most common configurations on 2020 Outbacks. If your vehicle has a different setup, consult the manual or the parts label on the blade itself.
- Driver-side blade: 26 inches
- Passenger-side blade: 20 inches
Using these measurements, you can shop for replacements by filtering for 26" and 20" blades in retailers or OEM Subaru parts catalogs.
Blade types and compatibility
Wiper blades come in several designs. The 2020 Outback can accommodate conventional frame blades, beam blades, or hybrid blades. Each design has its own benefits in terms of visibility, noise, and longevity.
- Conventional frame blades: Widely available and affordable; available in 26" and 20" for this model.
- Beam blades: Modern design with superior contact and durability in rain and snow; common sizes include 26" and 20".
- Hybrid blades: Combine frame durability with beam performance; also offered in 26" and 20" options.
Regardless of design, ensure you select the exact length combination—26 inches on the driver side and 20 inches on the passenger side—to ensure proper fit and clear wipe coverage.
Brands and where to buy
Popular, reliable options include Bosch, Rain-X, Valeo, Anco, and Subaru OEM blades. When shopping, look for the exact size pairing (26" driver, 20" passenger) and confirm that the blade attachment type matches your Outback's wiper arms (most likely a J-hook on 2020 models).
How to replace quickly (optional)
Replacing a blade is typically a two-step process: lift the wiper arm, rotate or unclip the old blade, and slide in the new blade until it clicks. Always perform the replacement when the wiper arms are in a resting position to prevent injury or blade misalignment.
Summary
For a 2020 Subaru Outback, the standard wiper blade sizes are 26 inches on the driver side and 20 inches on the passenger side. Choose from conventional, beam, or hybrid designs from reputable brands, and verify fit by cross-checking with the owner's manual or the retailer's listing. Properly matched blades improve visibility in rain and snow and maintain safe driving conditions.
