The front wiper blades on a 2021 Chevy Traverse are typically 26 inches on the driver’s side and 18 inches on the passenger side, with an 11-inch blade for the rear window.
Sizes can vary by market, trim level, or aftermarket replacements. To be certain, check your vehicle’s owner's manual or Chevrolet’s parts catalog, or inspect the current blades for size markings before purchasing replacements.

- Rear blade: 11 inches
Conclusion: The rear blade is typically 11 inches, but always confirm with your owner's manual or parts catalog if you’re outside the standard US market or if you have a special edition.
How to verify and replace
To ensure you buy the correct blades, confirm sizes before purchase and consider OEM versus aftermarket options.
OEM vs aftermarket blades
OEM blades from Chevrolet or authorized dealers guarantee exact fit and attachment style, while reputable aftermarket blades can offer lower prices but require you to verify compatibility with your model year and trim.

For a 2021 Chevy Traverse, plan on front wipers measuring 26 inches on the driver’s side and 18 inches on the passenger side, plus an 11-inch rear blade. Always confirm with official sources or by inspecting the current blades to ensure a correct, safe replacement. Clear vision is essential for safe driving, especially in adverse weather.
