Most GMC Sierra 1500s use a 22-inch driver-side wiper blade, with the passenger-side blade typically ranging from 20 to 22 inches depending on year and windshield configuration. The exact size for a specific truck should be verified in the owner's manual or by checking the current blades or a GM parts catalog.
Understanding the size landscape
The Sierra 1500 has seen changes in wiper blade sizing across generations. The sizes below reflect common configurations reported by parts catalogs and owners. Use this as a guide, but always confirm against your vehicle.
- Driver-side blade: typically 22 inches for most Sierra 1500 models

- Some early models used smaller passenger-side blades (around 18–20 inches); newer generations tend toward 20–22 inches
Exact sizes can vary by trim and options, so use this as a baseline and verify with your specific vehicle information.
How to confirm your exact size
The following steps help you determine the precise blade lengths for your Sierra 1500.
- Inspect the current blades for length markings, which are often printed on the blade or packaging.
- Remove the blades and measure from tip to base for each side to confirm lengths.
- Check the owner's manual or the GM parts catalog by year, trim, or VIN to verify recommended sizes.
- Consult an auto parts retailer with your year, trim, and VIN to cross-check the correct blade lengths.
If you’re unsure, bring the current blades or your VIN to a parts counter to ensure you get the correct sizes and a compatible blade type.
Shopping tips: choosing the right type and size
When shopping for wipers for a Sierra 1500, consider blade type and whether your truck uses a conventional, beam, or hybrid design. Sizes should match the driver and passenger sides as confirmed for your year/model.
- Common starting point: driver-side around 22 inches; passenger-side around 20–22 inches
- Beam or hybrid blades may offer better performance in rain and snow, but still must match the correct lengths
- OEM GM blades vs. aftermarket options: both can fit, but verify compatibility with your vehicle’s year and VIN
When in doubt, using a matched pair of blades sized to your Sierra 1500 ensures balanced contact and reliable wiping performance across the windshield.
Summary
In short, the GMC Sierra 1500 typically uses a 22-inch driver-side blade with a passenger-side blade that ranges from 20 to 22 inches, depending on year and windshield geometry. Always confirm the exact sizes for your specific truck via the owner's manual, GM parts catalog, or VIN-based part lookup, and consider replacing both blades as a matched set for optimal performance.
