The typical front wiper blade sizes for a 2011 GMC Sierra 1500 are 22 inches on the driver's side and 20 inches on the passenger side, with a 14-inch rear blade if your model has a rear wiper.
This article explains the standard sizes, notes possible variations by trim or aftermarket replacements, and guides you on how to verify the exact fit for your specific truck.
Front wiper blade sizes
To ensure you buy the correct front blades, use the following standard measurements for the Sierra 1500. These are the sizes most commonly installed on 2011 models.
- Driver's side: 22 inches
- Passenger's side: 20 inches
Replacing both front blades with the correct lengths helps maintain optimal contact with the windshield, improving visibility in rain and snow.
Rear wiper blade (if equipped)
Some 2011 Sierra 1500 configurations include a rear window wiper. If your truck has this feature, the blade size is typically:
- Rear blade: 14 inches
If your vehicle does not have a rear wiper, you can disregard this size. Always confirm with the owner's manual or a parts guide for your exact build.
How to verify the exact fit for your truck
Because trims and aftermarket replacements can vary, the most reliable way to confirm the blade sizes for your specific vehicle is to check the owner’s manual, use your VIN at an auto parts retailer, or measure the current blades and match the length to your windshield coverage.
Visit a store or consult a fitment guide to ensure you pick the right lengths and connector type (hook, pin, or side-lock) for your wiper arms. Proper fit prevents skipping or streaking and protects the wiper motor from strain.
Summary
For most 2011 GMC Sierra 1500 trucks, the front wipers are 22 inches on the driver’s side and 20 inches on the passenger side, with a 14-inch rear blade if the rear wiper is present. Always verify with the manual or a parts guide for your exact build, and replace blades regularly to maintain clear visibility.
