The 2017 Subaru Forester typically uses a 26-inch driver-side front wiper and a 17-inch passenger-side front wiper, with a 12-inch rear wiper.
These sizes reflect the common factory specifications for US-spec Foresters of that year. Wiper blade sizes can vary by region, trim, or aftermarket replacements, so it’s wise to confirm against your vehicle’s manual or by checking the label on the driver's door jamb or the packaging of the blades you’re purchasing.
Front wiper blade sizes
To ensure proper coverage and wipe quality, use the standard front blade lengths listed below. Some vehicles may tolerate slight length variations, but sticking to the recommended sizes helps prevent streaking or interference with the hood or cowl.
- Driver-side front blade: 26 inches
- Passenger-side front blade: 17 inches
Using the correct front blade lengths is important for a clear view during rain or snow. If your windshield has any unusual curvature or clearance issues, consult a parts guide or dealer for a precise fit.
Rear wiper blade size
The rear window on the 2017 Forester typically uses a single blade, commonly about 12 inches in length for US-spec models. Always verify to account for regional differences or aftermarket variants.
- Rear blade: 12 inches
Ensure the rear blade matches the vehicle’s mounting style and length. If your model uses a different rear blade size, check the owner’s manual or Subaru parts catalog for the exact specification.
How to verify the correct size
Ways to confirm the right sizes include checking the current blades for length markings, consulting the owner’s manual, or using the door jamb sticker that lists part numbers and blade lengths. If buying aftermarket blades, opt for models labeled as compatible with 2017 Subaru Forester front sizes of 26" and 17" and rear size of 12".
Buying tips and alternatives
Many brands offer universal mounting or adapters to fit a range of blades. When in doubt, purchase a matched front pair (26" and 17") plus a 12" rear blade, and ensure the product specifies compatibility with 2017 Forester models. Popular brands include Bosch, Rain‑X, Valeo, and ACDelco.
Summary
For a 2017 Subaru Forester, the standard setup is 26" driver-side front, 17" passenger-side front, and 12" rear. Always double-check with your owner's manual or the door jamb label, as regional variations can occur. When in doubt, bring the current blades to a parts counter or consult Subaru’s official parts catalog to confirm exact replacements.
