What is the steering wheel size in a toyota camry?

The size of the Toyota Camry's steering wheel varies slightly between model years, so for more complete information, You'll need to be a little more specific. For example, the 2019 model year has a steering wheel with a diameter of 14-1/2 inches and a grip circumference of 4-3/8 inches. Contrast that to the 2018 model year, which has a diameter of 15 inches and a grip circumference of 4-1/2 inches. Though this seems like a trivial difference, if You're buying a steering wheel cover, it can determine whether it's a precise fit or a baggy mess. My recommendation is to look for a wheel cover that's custom made for Your model year, so You'll have something that's akin to a second skin.
