The 2019 Subaru Legacy typically uses front wiper blades measuring 26 inches on the driver’s side and 16 inches on the passenger side, plus an 11-inch blade for the rear window. You can use Subaru OEM blades or reputable aftermarket replacements that match these sizes.
Front wiper blade sizes
The Legacy’s front wipers come in two sizes to cover the windshield effectively. Confirm the dimensions before purchasing to ensure full coverage and proper fit.
- Driver-side front blade: 26 inches
- Passenger-side front blade: 16 inches
Using the correct front blade sizes helps ensure maximum visibility in rain and snow and prevents streaking or poor contact with the glass.
Rear wiper blade size
The rear window uses a single wiper blade, typically 11 inches in length. This size is common among many Subaru models and fits most aftermarket 11-inch rear blades.
- Rear blade: 11 inches
Replace the rear blade when streaking, skipping, or poor contact with the glass reduces rear visibility.
Choosing blade types and installation tips
Blades come in various designs and materials. Here are practical considerations to help you choose and install the right blades for your Legacy.
- Blade type: beam (frameless) vs. traditional framed designs
- Material: rubber versus silicone; silicone blades often last longer but cost more
- Installation: front blades typically snap or hook into place; rear blades use a different mounting that can vary by trim or market
When replacing, check for proper seating and test wipe coverage to avoid streaks. Replacing both front blades at the same time can provide balanced performance.
Rear wiper replacement specifics
Some Legacy trims use a slightly different rear wiper mounting. Ensure you buy the 11-inch blade designed for the Legacy’s rear arm and follow the instructions in your owner’s manual or the product packaging for a secure fit.
Summary: For a 2019 Subaru Legacy, use front blades 26 inches (driver) and 16 inches (passenger) and an 11-inch rear blade. OEM Subaru blades or reputable aftermarket replacements in these sizes will fit. If in doubt, check the owner's manual or measure your current blades, and consider replacing worn blades promptly to maintain clear visibility in all weather.
