The standard front wiper blade sizes for a 2011 Subaru Outback are 26 inches on the driver's side and 17 inches on the passenger side, with an 11-inch blade for the rear window.
In this article, we explain the correct front and rear blade lengths for the 2011 Outback, how to verify them on your vehicle, and practical tips for selecting and installing replacement blades.
Front wiper blades
The Outback uses two different front blade lengths to cover its curved windscreen. Check your current blades if you’re unsure.
- Driver's side blade: 26 inches
- Passenger's side blade: 17 inches
These lengths cover most 2011 Outback models. If your blades differ, measure the blade length or refer to the owner's manual before purchasing replacements.
Rear wiper blade
The Outback’s rear window uses a shorter, single blade.
- Rear blade: 11 inches
11 inches is the typical rear blade size for the 2010–2014 Outback generation; if your car has a different model year, verify the correct length on the blade itself or in the manual.
Tips for choosing and installing blades
To help you shop and install blades more smoothly, consider the following tips.
- Measure or double-check the blade length against the packaging when buying new blades
- Choose a blade type appropriate for your climate (beam blades tend to perform well in rain and snow)
- Replace both front blades at roughly the same time for even wiping performance
- Use the correct adapters if upgrading from OEM to aftermarket blades
Following these guidelines will improve visibility and blade life for your 2011 Outback.
Summary
For a 2011 Subaru Outback, use front blades of 26 inches (driver) and 17 inches (passenger), plus a rear blade of 11 inches. Always verify lengths before purchasing, as some aftermarket options or trim variations may differ. Regular replacement ensures clear visibility in adverse weather.
