What is the size of a car's rear windshield?
3 Answers
The size of a small car's rear windshield typically has a thickness of 4mm and an area of 1050mm by 1050mm, which is an average value and may not apply to all sedans. Below are the functions and maintenance methods for car windshields: Functions of car windshields: Laminated glass is created by bonding a transparent adhesive plastic film between two or three layers of glass, combining the toughness of plastic with the hardness of glass, thereby enhancing the glass's resistance to breakage. Maintenance methods for car windshields: Applying a heat-insulating film to the windows is essential. In summer, a thin layer of heat-insulating film can be highly effective, not only blocking the intense sunlight but also providing insulation and UV protection.
It's really hard to give a direct answer to this question, as rear windshield sizes vary greatly between different car models. Based on the vehicles I've driven, a typical sedan usually has a length of around 1.2 meters and a height of about 0.5 meters, with an approximate area of 0.6 square meters. However, for fastback-style cars like the Tesla Model S, the rear window has a steeper slope and a larger area. As for SUVs like the Highlander, the rear window tends to be taller and more square-shaped, with the entire glass measuring up to 1.5 meters in width and 0.6 meters in height. I once helped a friend measure his old Lavida, and while I don't recall the exact numbers, the most accurate method is to use a tape measure to measure the length and width along the inner edge of the glass seal. Additionally, the position of the rear window defroster lines can affect the actual usable area, which is something to pay special attention to when applying window film.
The size you're asking about depends on the specific model. For compact cars like the Golf, the rear windshield is roughly 120×50 cm; midsize sedans such as the Camry are longer, around 140×55 cm; SUVs are even more substantial—the rear window on something like a CR-V can exceed 150 cm in width. When I last replaced glass, I checked the datasheet: curved rear windows actually have 10%-15% more surface area than flat ones. Many vehicles now feature privacy glass or gradient tints, which don't affect dimensions but make the glass appear smaller visually. For precise figures, always consult the repair manual for your exact model or measure the inner window seal frame directly.
