The typical front blade sizes for the BMW 428i are 26 inches on the driver’s side and 19 inches on the passenger’s side. Always verify the exact sizes for your model year and body style by checking the owner’s manual or the sticker on the driver’s door jamb.
Front wiper blade sizes for the 428i (F32/F33)
This section lists the standard front blade lengths used on the 428i, with notes on potential year and body style variations.
- Driver-side front blade: 26 inches
- Passenger-side front blade: 19 inches
Note: Some early or special editions may use slightly different lengths. Always verify with the vehicle’s documentation or a size lookup tool before purchasing replacement blades.
How to confirm the exact size for your car
There are several quick checks: look at the blades for length markings, inspect the door jamb sticker that lists blade sizes, or consult the owner’s manual. You can also remove and measure the blades for accuracy.
Rear wiper considerations (if applicable)
Most BMW 428i coupes do not have a rear wiper, but some convertible variants or certain trims may use a rear window wiper. If yours has one, sizes are smaller than the front blades and vary by year. Check your specific vehicle documentation or measure the blade to confirm.
Where to buy and how to replace
Front wiper blades for the 428i (26" driver, 19" passenger) are widely available from OEM and aftermarket brands. When purchasing, consider all-season blades and ensure the connector type matches your wiper arms (hook, pin, or bayonet). If unsure, have a parts specialist verify compatibility using your VIN.
Summary
For most BMW 428i models in the F32/F33 generation, plan for 26-inch driver-side and 19-inch passenger-side front wiper blades. Always confirm exact sizes via the door jamb sticker or owner’s manual, as occasional year-to-year variations can occur. Replacing blades in pairs helps maintain balanced wiping performance.
