The typical body width of a sedan ranges between 1600mm and 2000mm. Sedans are categorized into different classes: 1. Class A refers to compact cars; 2. Class B refers to mid-size cars; 3. Class C refers to full-size cars; 4. Class D refers to luxury cars. Class A compact cars have a wheelbase between 2500mm and 2700mm, a body length between 4200mm and 4600mm, and an engine displacement between 1.6L and 2.0L. Class B mid-size cars have a wheelbase between 2700mm and 2900mm, a body length between 4500mm and 4900mm, and an engine displacement between 1.8L and 2.4L. Class C full-size cars have a wheelbase between 2800mm and 3000mm, a body length between 4800mm and 5000mm, and an engine displacement exceeding 2.4L. Class D luxury cars have a wheelbase exceeding 3000mm, a body length exceeding 5000mm, and an engine displacement exceeding 3.0L.

I've been driving sedans for many years, with the body width typically around 1800 millimeters, which is about 1.8 meters. For compact cars like the Toyota Corolla, the width is approximately 1760 millimeters, making parking in spaces quite handy. Mid-size sedans such as the Honda Accord have a width of 1840 millimeters; the slightly wider body gives a more spacious feel, making it less cramped inside. However, in some narrow city intersections or older garages with a width limit of two meters, wider vehicles like those 1900-millimeter SUFs can be tricky to maneuver. When choosing a car, it's essential to consider the driving environment—narrower roads call for narrower cars. Generally, standard sedans range from 1700 to 1900 millimeters in width, offering a stable and practical driving experience.

As a car enthusiast, I often pay attention to the dimensions of new cars. The width of sedans varies from around 1720mm for compact models like the Volkswagen Golf, to 1920mm for luxury versions like the Mercedes-Benz S-Class. The average width is approximately 1800mm, a design that helps balance handling and space: narrower cars are more agile and fuel-efficient, while wider ones offer better stability in crosswinds but consume slightly more fuel. European cars tend to be narrower, around 1760mm, while American cars are typically wider, up to 1850mm. When driving in practice, parking space lines are usually spaced at 2.5 meters, allowing most cars to maneuver easily. However, extra-wide cars, like some models at 1950mm, require more attention to avoid scraping risks. Understanding these details helps in choosing the right car model.

In my understanding, a body width of around 1800mm represents the mainstream design balance point. It ensures both a sleek exterior appearance and sufficient interior lateral space, allowing three to four passengers to sit comfortably in a row. Compact models may start from 1700mm, while full-size vehicles can reach up to 1900mm, depending on the manufacturer's style. This range strikes a balance between aesthetics and practicality: wider bodies offer better stability at high speeds but can be challenging in narrow alleys, whereas narrower ones are more maneuverable yet space-constrained. Common vehicles in daily life, such as standard family sedans, typically fall within this range. When choosing a car, it's best to consider your everyday needs.
