What are the standard dimensions for the length, width, and height of a sedan?

The standard dimensions for a sedan are a length of 4.8 meters (those close to 5 meters are considered full-size sedans), a width of 1.8 meters, a height of 1.5 meters, and a turning radius between 5 to 6 meters. A sedan is defined as a vehicle designed to carry passengers and their personal belongings, with seating arranged between two axles, and a maximum seating capacity of nine, including the driver. Apart from the passenger compartment, sedans have visibly distinct front and rear sections, making it easy to identify the engine compartment, passenger cabin, and luggage compartment (in some regions, this body style is referred to as a three-box design). Sedans are specifically distinguished from trucks, pickups, SUVs, buses, and minibuses, commonly referred to as small cars. Sedans are also categorized into several classes. For household use, car lengths typically range from 3800mm to 4300mm, widths from 1600mm to 1800mm, and heights from 1400mm to 1600mm. Vehicle Length: Length is the most influential parameter affecting a car's purpose, functionality, and ease of use. Therefore, vehicle classes are generally divided based on length. A longer body means more longitudinal space, but excessive length can make turning and parking inconvenient. There is a significant difference in driving feel between a 4-meter-long car and a 5-meter-long one, with most small to medium-sized passenger cars being around 4 meters in length. Vehicle Width: Width primarily affects passenger space and maneuverability. For passenger sedans, to ensure comfortable seating for three passengers side by side, the width generally needs to be around 1.8 meters. Due to increased safety requirements, door panel thickness has increased, leading to a general increase in vehicle width. However, an overly wide body can reduce convenience in urban driving and parking. Vehicle Height: Height directly impacts the center of gravity (and thus handling) and interior space. Most sedans are under 1.5 meters in height, significantly lower than the natural seated height of a person, mainly to lower the vehicle's center of gravity and ensure stability during high-speed cornering. MPVs and vans, designed for spacious headroom and cargo space, are generally taller (over 1.6 meters), but this raises the center of gravity, resulting in greater body roll during turns.
I'm quite familiar with car dimensions. Compact cars typically refer to models like the Honda Fit or Toyota Yaris, with standard lengths ranging from 4.0 to 4.5 meters, widths around 1.7 to 1.8 meters, and heights approximately 1.4 to 1.5 meters. I often encounter this range during vehicle inspections, as it's designed based on urban parking needs and road regulations. The shorter length makes turning easier on crowded streets, the width ensures driving stability to prevent rollovers, and the moderate height provides good visibility for road conditions. In practice, different brands may have slight variations—for example, the Honda Fit measures 4.03 meters long, 1.69 meters wide, and 1.53 meters tall. These dimensions make it easier to park in standard spots, eliminating the hassle of finding larger parking spaces. The compact size also reduces weight and fuel consumption, making it ideal for commuters, though the interior space needs thoughtful layout to avoid feeling cramped.
