The typical configuration for most Mercedes GLC models is 26 inches on the driver's side, 20 inches on the passenger's side for the front wipers, and 11 inches for the rear wiper. Always verify with your vehicle's manual or an up-to-date parts lookup by year and market.
In this article, we provide the standard sizes used across common GLC generations and explain how to confirm the exact fit for your specific year, trim, and region, along with tips on finding the right blades and connector type.
Standard blade sizes for the GLC
The sizes below reflect the typical front and rear blade lengths used on many GLC SUVs (including X253 and newer W167 variants). Some markets or model-years may differ slightly, so check your manual or a parts lookup if in doubt.
- Driver-side front wiper blade: 26 inches
- Passenger-side front wiper blade: 20 inches
- Rear wiper blade: 11 inches
Note: If your GLC has a different rear hatch or a specialized configuration, the rear blade length might vary. Always measure or verify before purchasing replacement blades.
How to verify and replace
To ensure you buy the right blades, follow these steps to confirm the exact sizes and compatibility for your specific vehicle.
- Consult the owner's manual or the door jamb information placard for the official blade lengths used on your GLC.
- Inspect the current blades or their packaging to read the length and connector type.
- Measure the blades if you are unsure: measure from the blade tip to the opposite end along the curve to confirm length.
- Use an online parts lookup tool by entering your model year or VIN, or ask a trusted auto parts retailer for the correct fit.
- Check the connector type (typically J-hook on many Mercedes models), and ensure your replacement blades match the connector and mounting style.
Having the correct sizes and connectors ensures proper fit, effective wiping, and avoids blade chatter or streaks.
Summary
For most Mercedes GLC models, the standard front wiper sizes are 26 inches on the driver’s side and 20 inches on the passenger’s side, with an 11-inch rear blade. Always verify by checking the owner's manual, the blade itself, or a VIN-based parts lookup, since year, trim, and regional differences can affect exact fit. When in doubt, ask a parts specialist or use a reputable retailer’s fitment tool to match your exact vehicle.
