The front wiper blades are typically 26 inches on the driver’s side and 16 inches on the passenger side, with a 12-inch rear blade for the 2020 Subaru Forester. These dimensions are standard for most models from that year, but it’s wise to verify for your specific vehicle.
This article breaks down the exact blade sizes, how to verify them for your exact car, and practical tips for replacement and maintenance to keep your windshield clear in all weather conditions.
Front wiper blade sizes
To ensure full coverage and effective clearing, the Forester uses two front blade lengths: a 26-inch blade on the driver’s side and a 16-inch blade on the passenger side. When shopping, you’ll often see these sold as a two-blade set labeled for Subaru Forester 26"/16".
- Driver’s side front blade: 26 inches
- Passenger’s side front blade: 16 inches
Note: While these are the typical sizes, some trims or aftermarket replacements may vary slightly in connector style. If in doubt, check the current blades again or confirm with Subaru’s parts site or your vehicle VIN.
Rear wiper blade size
The Forester’s rear wiper blade is usually 12 inches in length. This size is common across 2013–2021 Forester models, including the 2020 version, but always confirm if you’re replacing with an aftermarket part.
- Rear wiper blade: 12 inches
When replacing, ensure you select the correct rear blade connector style for your model, and consider a winter-ready blade if you live in very cold or snowy conditions.
How to verify your exact sizes
Because blade sizes can vary by trim, production run, or aftermarket modifications, use these quick methods to confirm the right blades for your specific Forester:
- Check the owner's manual wiper section for the official sizes.
- Inspect the current blades for any size markings when you remove them.
- Consult Subaru’s official parts site or a dealer with your VIN for an exact match.
After obtaining the correct sizes, replace the blades by releasing the wiper arm, removing the old blade from its connector, attaching the new blade, and reseating the arm carefully.
Maintenance and replacement tips
Front blades typically should be replaced about every 12 months, or sooner if you notice streaking, skipping, or chattering. In winter regions, consider winter or all-weather blades to improve performance in snow and ice, and inspect the wiper arms for stiffness or damage.
Summary: For a 2020 Subaru Forester, the standard front blade sizes are 26 inches on the driver’s side and 16 inches on the passenger side, with a 12-inch rear blade. Always verify with your manual or dealership for any trim-specific differences.
