What are the general dimensions of parking spaces?

[MacIker]

According to the "Specifications for Setting On-Street Parking Spaces on Urban Roads," the standard dimensions of parking spaces are determined based on vehicle size. Small parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. Single-lane turning lanes should be no less than 3.5 meters wide, while double-lane turning lanes should be no less than 5 meters wide. Turning sections should accommodate a vehicle's ability to make a single turn, and for safety or to accommodate medium-to-large vehicles, they are often set to 6 meters or more. Specific details are as follows: (Length ≤ 6m, width ≤ 1.8m) vehicles: The spacing between vehicles should be no less than 0.5 meters, and the spacing between vehicles and walls or the ends of parking spaces should also be no less than 0.5 meters. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m) vehicles: The spacing between vehicles should be no less than 0.7 meters. Small vehicle parking spaces: Length ≥ 5 meters, width 2.2-2.5 meters. Large vehicle parking spaces: Length 7-10 meters, width 4 meters, depending on the vehicle model. Per the "Code for Design of Garages," the dimensions for small vehicle indoor parking spaces are as follows: The design dimensions for small vehicles are 4.8m (length) x 1.8m (width) x 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) x 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small vehicles and side walls should be 0.6m, and the minimum distance to front and rear walls should be 0.5m. Modern underground garages have large floor areas and numerous parking spaces. To ensure smooth vehicle passage, driveways are planned to be relatively wide. Driveways, as horizontal passages dedicated to parking spaces, account for the primary floor area allocated to parking spaces and often occupy 50% or more of the total parking space floor area. Parking space arrangements can be categorized into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Specifics are as follows: Parallel parking spaces: Standard length of 6 meters, width of 2.5 meters. Angled parking spaces: Diagonal length of 6 meters, width of 2.8 meters, with a vertical distance between two diagonal lines maintained at 2.5 meters. Perpendicular parking spaces: Length ≥ 5 meters (typically set at 6 meters), width of 2.5 meters. The optimal standard size is 2.5m x 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces should not be set on roads with a width of less than 6 meters for motor vehicle passage. Pedestrian crossings, expressways, and main roads are also prohibited from having parking spaces. Within urban road areas, government authorities may designate parking spaces where pedestrian and vehicle traffic is not impeded. On-street parking spaces should avoid disrupting non-motorized vehicle passage and should not encroach on non-motorized vehicle space. They should not be set near intersections, building entrances, or bus stops. Parking space types and durations should be indicated via signage, and impacts on motor vehicle traffic should be minimized. Additionally, on-street parking spaces should not have ground locks to prevent private occupation. Roads prohibiting on-street parking may have barriers, posts, or curbs installed. After removal or cancellation of parking spaces, all related signs, markings, and facilities should be promptly cleared to prevent continued parking and ensure road safety. Furthermore, on-street parking spaces should not be set within 200m~300m of off-street public parking lots. Quantitative rules for on-street parking space setup: The "Specifications for Setting On-Street Parking Spaces on Urban Roads" provides quantitative rules based on road width. For two-way roads: if the actual road width exceeds 12 meters, parking spaces may be set on both sides; if between 12m and 8m, on one side; if less than 8m, no parking spaces. For one-way roads: if the actual road width exceeds 9 meters, parking spaces may be set on both sides; if between 9m and 6m, on one side; if less than 6m, no parking spaces. For disabled parking spaces, the specifications require that on-street parking spaces should include disabled parking spaces, accounting for no less than 2% of the total. For parking lots with over 20 spaces, at least one disabled parking space should be provided. Parking space marking colors: White: Paid parking spaces; Blue: Free parking spaces; Yellow: Reserved parking spaces; Time-limited parking spaces: Dotted borders, 10cm line width; permitted parking times marked inside the border, with numbers 60cm high. Disabled parking spaces: Special markings; yellow grids on both sides indicate no-parking zones for disabled boarding/alighting areas. Other vehicles must not occupy disabled spaces. Special pavement markings indicate exclusivity. Yellow grid lines: 120cm width; outer line width: 20cm; inner fill line width: 0cm; 45° angle to outer lines; outer line length matches parking space marking length. Prohibited areas for on-street parking spaces: Fire lanes, road sections with no-parking signs/markings, or construction zones impeding traffic; Roads with disaster relief or emergency evacuation functions; Sidewalks (if set, must not encroach on blind paths); Near building entrances; Intersections, railway crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, tunnels, and areas within 50m of these locations; Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for facility use); Within 20m of intersection channelized areas; Near underground utility access points or within 15m of such locations; Within 200m of off-street parking lot entrances; Near roadside

I drive a lot and have parked in many spaces. Standard parking spaces are generally about 2.5 meters wide and 5.3 meters long, which suits most small cars. When I drive a regular sedan, this space is sufficient, and I don’t hit other cars when opening the doors. However, some narrow spaces may only be 2.2 meters wide, making it easy to scratch the doors—I’ve encountered this a few times, and it’s quite annoying. Dimensions vary in different places; for example, spaces in shopping malls tend to be wider, while those in garages may be tighter. There are also angled parking spaces, which have similar widths but slightly shorter lengths, saving space. When parking, I always check the surroundings first and choose a suitable spot to avoid issues. Additionally, national standards specify minimum dimensions, but private parking lots sometimes cut corners, so it’s good to stay alert.
