Do front and rear wiper blades differ in size? Yes, front and rear wiper blades often differ in size due to their distinct functions and the varying shapes of vehicle windshields and rear windows. Front wiper blades are generally longer to cover a larger surface area, while rear wiper blades are shorter, designed specifically for smaller rear windows.
Why Do Front and Rear Wiper Blades Differ in Size?
The difference in size between front and rear wiper blades is primarily due to the design and function of vehicle windows. Front windshields are typically larger and require longer blades to effectively clear rain, snow, and debris. In contrast, rear windows are usually smaller and need shorter blades.
