The driver's-side wiper blade on most Subaru Outback models is 26 inches. The passenger-side blade is typically 16 inches, though some older generations used different lengths. Always verify for your exact year and trim.
Wiper blade sizing can vary across generations and markets. To ensure you buy the right fit, check your owner's manual, inspect the blade currently installed, or measure the blade yourself before purchasing replacements.
How to confirm the correct size
Use these steps to confirm the correct length before buying a replacement blade.
- Check the owner's manual or Subaru's official parts pages for your model year; the specification is listed there.
- Examine the blade that is currently installed: many blades have the length stamped on the blade near the connector.
- Remove the blade and measure it: place a tape measure at the center of the blade's mount and extend to the tip of the blade to get the full length in inches (do not measure the arm).
If you are replacing both front blades at once, the typical setup for many Outbacks is a 26-inch driver-side blade and a shorter passenger-side blade (commonly around 16 inches), but verify for your specific year and trim.
Summary
In most Subaru Outback models, you should expect a 26-inch wiper blade on the driver's side, with the passenger side around 16 inches. Always confirm with your exact year to ensure a perfect fit.
