A windshield cover size chart matches a vehicle’s glass dimensions to a product size class; the most reliable approach is to measure your windshield directly and compare those measurements to the manufacturer’s published chart.
For the full breakdown, see our best Windshield Cover guide.
Buying a windshield cover by guessing the size usually ends with a cover that flaps in the wind or leaves bare glass exposed to frost. There is no universal chart that fits every vehicle, because each brand publishes its own size classes and the dimensions of windshields vary widely between compact cars and full-size trucks. Instead of relying on your car’s make and model alone, measuring the glass directly takes about two minutes and gets you the right fit on the first try.
Why Measuring Your Windshield Beats Relying On Make And Model
Two different trim levels of the same SUV can have different windshield dimensions, and aftermarket accessories like bug deflectors change the fit further. Windshield cover size charts are based on glass measurements, not vehicle identification numbers. The branded size classes — Compact, Standard, XL, and XXL — are consistent within a product line but shift between manufacturers.
| Size Class | Width (inches) | Height (inches) |
|---|---|---|
| Compact | 60.0 | 42.0 |
| Standard | 69.0 | 42.0 |
| XL | 73.5 | 42.5 |
| XXL | 78.0 | 45.0 |
Always check the specific chart for the cover you are buying.
How To Measure Your Windshield The Right Way
Measure forming a plus sign across the glass: find the widest point horizontally (usually near the bottom edge, from the inside edge of the rubber seal on one side to the inside edge on the other), then measure vertical height through the center of the windshield where the glass is tallest. Measuring near the pillars or at the top edge can understate the height because windshields taper upward. Write down both numbers and round up to the nearest half inch.
Once you have your windshield’s width and height, match them against the size chart of the cover you want. If your measurement sits near the top of a size class’s range, consider stepping up one size for a full seal.
Windshield Covers Vs. Full Vehicle Covers: Different Charts Altogether
Full car cover size charts are based on overall vehicle length, width, and height — not the glass dimensions. A cover sized to wrap a sedan’s entire body will be far too large to function as a frost shield for the windshield alone, and a windshield cover will not stretch over a car’s mirrors or roof racks. Never swap one chart for the other. For a full car cover, use the vehicle manufacturer’s published dimensions and check for add-ons like antennas, spoilers, and top boxes that a fitted cover must clear.
Common Sizing Mistakes That Lead To A Poor Fit
The most frequent error is measuring the windshield’s outer frame instead of the glass itself. The second is ignoring curvature — a steeply sloped windshield may need a slightly larger cover than width and height alone suggest, because the cover must follow the glass curve. For full vehicle covers, forgetting side mirrors, roof rails, or a rear spoiler can result in a cover that billows or drags on the ground. If your car has any of those features, look for a chart that includes “mirror pocket” dimensions or a length range that accounts for them.
Snow and frost covers are designed to protect the glass from ice buildup, but a loose cover lets wind sneak underneath and a cover that is too small leaves exposed glass that still frosts overnight. Taking three minutes to measure correctly saves the frustration of returning a cover that does not fit and ensures the cover actually works when the temperature drops.
FAQs
Can I use a car cover size chart for my windshield cover?
No, the two are not interchangeable. Car cover charts use overall vehicle length, width, and height, while windshield cover charts are based on the glass dimensions alone. Using a car cover chart to pick a windshield cover will result in a size that is far too large.
What if my windshield measurement falls between two sizes?
Choose the larger size. A slightly oversized windshield cover can be pulled taut with the side mirrors or straps, while an undersized cover leaves gaps that let frost form on exposed glass and are more likely to blow off in wind.
Do windshield cover size charts include mirrors or wipers?
No, windshield-only charts cover the glass surface only. Side mirrors and wiper arms are accommodated by the cover’s elastic edge or straps, not by the size selection. For full vehicle covers, look for charts that explicitly list mirror pocket measurements.
