It might seem difficult to figure out exactly what size sun shade is right for your car, but don’t be intimidated. For one thing, many sun shades are designed to be universal fit—or, at least, universal-ish. These sun shades will be oversized for the vast majority of windshields, and will fold to fit. For those that offer different sizes, make sure to consult the charts provided before you buy, because you might be surprised at what size you actually need. Windshield size isn’t always correlated with car size; the Honda Civic, for example, has a larger windshield than some pickup trucks.
