The front wiper blades on the Lexus GS300h are typically 26 inches on the driver’s side and 18 inches on the passenger’s side, with a rear blade around 12 inches where a rear wiper is fitted.
Wiper blade sizes can vary by market and model year, so it’s important to confirm the exact measurements for your car using the owner’s manual, VIN-based parts lookup, or guidance from an authorized dealer or reputable parts retailer before purchasing replacements.
Front wiper blade sizes
The front blades on most GS300h variants come in two lengths to match the sweeping area of the windshield. The standard configuration is as follows:
- Driver side blade: 26 inches
- Passenger side blade: 18 inches
These dimensions cover the typical GS300h models from the early- to mid-2010s and are commonly supported by aftermarket suppliers. Always verify against your specific year and market to avoid a mismatch.
Rear wiper blade size
On GS300h models equipped with a rear wiper, the common rear blade size is:
- Rear blade: 12 inches
If your vehicle does not have a rear wiper, this size won’t apply. When ordering, double-check the OEM part number to ensure compatibility with your trim, market, and year.
How to confirm the exact size for your vehicle
To ensure a precise fit, use these methods:
- Consult the owner's manual or an official maintenance guide for your specific model year and market.
- Measure the current blades if you have them handy, including the center-to-center length for each blade.
- Use a VIN-based parts catalog or ask an auto parts retailer to verify compatibility by year, trim, and region.
Accuracy matters: even a one-inch difference can affect performance and clearance. When in doubt, bring your current blades or your VIN to a parts counter for guidance.
Summary
For the Lexus GS300h, plan on 26-inch driver-side front blades and 18-inch passenger-side front blades, with a typical 12-inch rear blade if your model includes a rear wiper. Sizes can vary by year and market, so always verify with official documentation or a trusted parts source before purchasing replacements. A quick cross-check with the owner’s manual or VIN-based lookup helps ensure you get the right fit the first time.
