For a 2017 Highlander, the standard front wiper blades are 26 inches on the driver's side and 20 inches on the passenger side, with a 12-inch blade for the rear window. This sizing is typical across most trims, but you should confirm for your exact vehicle model and any aftermarket replacements.
Wiper blade sizes can vary by trim or aftermarket replacements, so verifying before purchase helps avoid fit issues. This article breaks down the typical sizes and how to check them on your Highlander.
Size by position
Front blades
The front windshield uses two different lengths. The driver’s side blade is normally 26 inches, while the passenger side blade is typically 20 inches. These lengths are designed to fit the Highlander’s curved windshield and ensure even wiping across the pane. When shopping, look for a 26"/20" pair to fit a 2017 Highlander.
Rear blade
The rear blade is generally 12 inches in length and fits the tailgate-mounted wiper. Some trims or aftermarket lines may offer 11" variants, so it’s wise to verify by measuring the existing rear blade or consulting the owner’s manual or a parts diagram for your VIN.
How to confirm and replace
To confirm sizes and replace blades, you can use a few quick checks. Start with the owner's manual or Toyota’s official parts diagrams for your exact trim. If you’re replacing only one blade, measure the length of the current blade from end to end. When replacing both front blades, choose a 26"/20" pair keyed to your Highlander’s front mount type. For the rear, select a 12" blade with the correct connection style for the tailgate wiper.
When in doubt, bring the vehicle’s year, make, model, and your VIN to an auto parts store or dealer parts desk. They can pull the exact OEM-compatible blade lengths and the correct connection adapters for your model.
Summary
For a 2017 Toyota Highlander, plan on front wipers of 26 inches on the driver's side and 20 inches on the passenger side, plus a 12-inch rear blade. Always verify against your specific vehicle's manual or by measuring the current blades, as some trims or aftermarket products may differ slightly.
