The following sizes are what most owners report for this model year, and they appear in OEM and aftermarket catalogs.

How to confirm the right wiper blade size for your truck
To ensure you get the exact fit, use these reliable methods before buying new blades.
- Check the owner's manual or the label on the driver's sun visor for blade size recommendations.
- Measure the length of the current blades from tip to tip with the blades removed, or measure the exposed portion along the windshield edge if removing is not feasible.
- Consult the vehicle’s VIN with an auto parts retailer or GM dealer; most parts databases will return the correct blade sizes for your exact truck configuration.
- Consider hood clearance and wiper arm length; if in doubt, bring a blade sample or measure before purchasing to avoid fitment issues.
If you still aren't certain, ask a parts counter person or consult the vehicle's manual. They can confirm the sizes for your exact year and trim level.
Notes on variations
Some aftermarket kits offer 22" driver and 20" passenger blades for certain windshield configurations, or 22"/18" for others. Always verify with the retailer using your truck's details if you plan to mix brands or switch blade lengths.
In practice, the 22-inch driver blade paired with an 18-inch passenger blade is the most commonly reported configuration for a 2002 Sierra 1500. If you replaced blades previously with 20" passenger blades and you’re unsure, re-check the fit before purchase.
Summary
For a 2002 GMC Sierra 1500, expect a 22-inch driver-side blade and an 18-inch passenger-side blade as the standard pairing. Confirm with official documentation or a parts specialist if you have a non-standard cab or aftermarket windshield features. Matching the correct sizes ensures full coverage and optimal visibility.
