What size wipers do I need for a 2018 Subaru Crosstrek?
The standard wiper setup for a 2018 Subaru Crosstrek in many markets is a 26-inch driver-side blade and a 16-inch passenger-side blade, with a 12-inch rear blade. Sizes can vary by region or trim, so it’s best to confirm against your owner's manual or Subaru parts catalog.
Front wiper blade sizes
The front windscreen requires two different blade lengths to match the sweep pattern and windshield curvature. Using the correct sizes ensures optimal visibility and even wear across the blade edge.
- Driver-side front blade: 26 inches
- Passenger-side front blade: 16 inches
Front wiper sizes can vary slightly depending on regional specifications or aftermarket options, but the 26"/16" pairing is standard for the 2018 Crosstrek in the United States and many other markets. Always double-check by consulting your manual or a trusted parts supplier.
Rear wiper blade size
The rear wiper on the Crosstrek is a separate measurement and is generally smaller, designed to sweep the rear window without overhang. For the 2018 Crosstrek, the typical rear blade length is about 12 inches.
- Rear wiper blade: 12 inches
Note that some regional versions or trims may use slight variations in rear blade length. If your rear wiper looks misaligned or stretches beyond the glass, verify the exact size with Subaru parts or your dealership.
How to verify and replace
To ensure you get the right blades, you can:
- Check the owner’s manual or Subaru’s official parts catalog for exact blade lengths by vehicle identification number (VIN) or trim level.
- Measure the current blades from tip to tip when they are resting, including any overhang beyond the wiper arm base.
- Take the old blades to an auto parts store to compare lengths and connectors.
Replacing wipers is straightforward: lift the arm, detach the old blade, attach the new blade with the correct connector, and lower the arm gently. Wipe the windshield edges with a lint-free cloth to remove debris for optimal performance.
Summary
For a 2018 Subaru Crosstrek, plan for front wipers of 26 inches on the driver side and 16 inches on the passenger side, plus a 12-inch rear blade. Always verify with your manual or a parts retailer to account for regional variations or trim-specific configurations. Regular checks help ensure you have the right size and a proper fit for clear visibility.

Can I use a 28 wiper instead of 26?
No, you should not use a 28-inch wiper instead of a 26-inch one because it will likely cause problems, such as the blades hitting each other, damaging the wiper motor due to added stress, or leaving uncleared areas on the windshield. The correct size ensures the wipers function properly, stay in contact with the glass, and do not cause premature wear or damage to the system or the glass itself.

Problems with using a longer blade
- Physical interference: The longer blades may hit each other or the sides of the windshield, which can damage the blades, motor, or even the car's paint.
- Reduced visibility: The longer blades may not conform to the window's shape properly, creating streaks and uncleared spots, which reduces visibility.
- Increased stress on the motor: The wiper motor wasn't designed for the extra weight and drag of a longer blade, which can lead to premature wear and tear or eventual failure.
- Potential for glass damage: The uneven pressure from an oversized blade could potentially scratch or crack the windshield.
How to find the right size
- Check your vehicle's owner's manual for the recommended sizes.
- Visit an auto parts store; they have guides that can look up the correct size for your car's make and model.
- Remember that the driver's and passenger's side wipers can sometimes be different lengths on the same vehicle.
