For a 2011 Subaru Legacy, the standard front wiper blade sizes are 26 inches on the driver’s side and 16 inches on the passenger side. The sedan typically does not have a rear wiper, while the wagon variant uses a smaller rear blade, around 12 inches. This article explains the sizes, how to verify them, and tips for choosing replacements.
Front wiper blade sizes
The following list covers the typical front blade lengths used on the 2011 Legacy. Always confirm against your exact model and body style, as some trims or aftermarket replacements may vary slightly.
- Driver’s side front blade: 26 inches
- Passenger’s side front blade: 16 inches
These two blade lengths are the standard pairing for most 2011 Legacy sedans. If you’re replacing both blades at once, you’ll often see a two-blade setup marketed as 26"/16".
Rear wiper presence and size
Rear wiper availability and size depend on the body style. The sedan version of the 2011 Legacy generally does not have a rear wiper. If you own a Legacy Wagon, a rear blade is typically required, though it is shorter than the front blades.
- Sedan: usually no rear wiper
- Wagon (rear hatch): rear blade approximately 12 inches
When replacing a rear blade on a Legacy Wagon, measure the current blade or check the owner's manual to ensure you select the correct length, as some model years use slightly different rear blade lengths.
How to verify and replace
To be certain you have the right sizes, verify with the vehicle’s manual or by measuring the blades currently on the car. Here are practical steps to confirm and replace:
- Open the hood and locate the wiper arms. Lift each arm away from the windshield to extend the blade.
- Measure the full length of the blade from end to end for both the driver and passenger sides. If you’re unsure, bring the existing blades to the store when shopping for replacements.
- For the rear blade (if applicable), repeat the measurement on the rear hatch area and ensure the replacement matches the measured length.
- Choose blade types that fit your climate and driving conditions (aero/beam blades are common for Subarus and often deliver better performance in rain and snow).
Once you have the correct sizes, you can install the new blades following the manufacturer’s instructions or have them installed at a shop or auto parts counter. Blades are typically attached via a quick-release adapter; ensure the correct connector is used for your wiper arm.
Tips for choosing blades
Beyond size, consider blade design and quality. Beam blades tend to perform well in a range of conditions, while traditional framed blades can be more affordable. Look for rain-sensing capabilities if your model has such features, and check for warranty coverage. Replacing both front blades at the same time helps ensure even contact and consistent visibility.
Summary
For the 2011 Subaru Legacy, expect 26-inch driver-side and 16-inch passenger-side front wiper blades. The sedan typically lacks a rear wiper, while the Wagon may use a roughly 12-inch rear blade. Always verify against your specific vehicle configuration and consider reputable blade designs to optimize visibility in all weather conditions.
