What size is the windshield on a 2018 Silverado?
The windshield size for a 2018 Chevrolet Silverado isn’t published as a single, universal specification. In practice, the glass is a single curved panel sized to the truck’s body, with typical outer dimensions around the mid-60-inch width and about 28–30 inches of height, but exact measurements vary by cab configuration, trim, and production batch. For precise dimensions, check the OEM windshield part number or measure the actual glass on the vehicle.
Understanding variation in the 2018 Silverado windshield
The 2018 Silverado comes in several cab configurations (Regular, Double, Crew) and bed lengths; individual windshields are sourced to fit those variants. Consequently, there isn’t one standard size that covers all 2018 Silverado models.
To determine the exact dimensions for your specific truck, follow these steps:
- Identify your exact vehicle configuration (model, cab style, bed length) and confirm the VIN to match the correct part variant.
- Check the GM Parts Catalog or a dealer portal to locate the OEM windshield part number and the published dimensions for that glass.
- If you’re replacing glass, measure the actual windshield: width from the outer edge of one pinch-welt to the other, and height from the top edge to the bottom edge, accounting for any curvature.
- Verify that the replacement part includes the correct molds/seals for your trim and year, and that it matches the installation guide.
These steps will help ensure you obtain an exact fit for your vehicle, since exact numbers can vary by body style and production batch.
Summary
In short, there is no single published dimension for every 2018 Silverado windshield. Expect a width in the mid-60s inches and a height around 28–30 inches, but confirm with the GM Parts Catalog or by measuring your vehicle to ensure a proper fit when buying or replacing the glass.
