There isn’t a single universal size for every 2011 GMC model. The blade lengths depend on the specific model and trim. In general, GMC SUVs from that year tend to use large driver-side blades paired with somewhat shorter passenger blades, while GMC pickups often use two front blades in the low-to-mid 20s and upper-teens, but exact sizes vary. Verify the exact specification for your vehicle to ensure a proper fit.
Understanding the question’s scope helps: “2011 GMC” covers a family of vehicles including SUVs and pickups, each with its own wiper blade configuration.

Below are the typical front-blade configurations seen on common 2011 GMC models, followed by tips to confirm the correct sizes for your specific vehicle.

How to confirm the exact blade size for your 2011 GMC
To ensure you buy the correct blades, use these steps to confirm the exact size for your vehicle.
- Check the owner’s manual or the label on the current wiper blades, which often lists the blade length for each side.
- Measure the blades you remove: use a ruler or tape measure from the blade’s tip to its base to determine the full length on each side.
- Consult an online parts catalog or dealership/parts retailer by entering the specific model year, make, and model (and trim if possible) to retrieve recommended sizes.
- Bring the old blades to the store or use a blade-size finder tool on a retailer’s website if you’re buying in person or online.
- Consider blade style and climate: if you drive in snow or freezing rain, you might prefer winter or all-season blades, which can be sold in specific lengths compatible with your model.
When in doubt, asking a parts specialist with your VIN (Vehicle Identification Number) can help ensure you get the exact blades for your particular vehicle configuration.
