Front wiper blade sizes for the 2018 Silverado 1500
Before listing the sizes, note that blade length can vary by cab configuration and windshield shape. The following sizes cover the most common factory specifications for the 2018 Silverado 1500.

The front blade sizes refer to the windshield wipers. Depending on your specific cab configuration or aftermarket replacements, there could be variations. If your vehicle uses a rear wiper (some variants may), its size is not covered here and should be confirmed separately.
How to confirm your exact blade size
Check the owner's manual or the packaging of the blades you’re considering. You can also inspect the current blades, measure them, or look for a size label on the blade itself. When purchasing, match the size to the recommended OEM pairing for your cab type.
Replacing wiper blades: quick tips
To replace, lift the wiper arm, release and remove the old blade, attach the new blade using the connector style shown on the packaging, and secure the arm back against the windshield. Test the sweep to ensure full contact and smooth operation in rain or snow.
Variant considerations
In rare cases, some aftermarket blade sets or dealer-installed options may use a different pairing. If you have a non-standard setup or prefer a universal blade, verify compatibility with the part number and your vehicle’s VIN.
Summary: For a 2018 Silverado 1500, the typical front wiper blade sizes are 22 inches on the driver’s side and 21 inches on the passenger’s side. Always verify with the owner's manual or the current blades to confirm the exact sizing for your cab configuration and trim.
