A standard parking space in France measures 5 meters long and 2.30 meters wide. This definition, established by the NF P 91-100 standard for public parking lots and NF P 91-120 for private parking lots, has served as a reference since the 1990s. The problem: the average width of vehicles sold in France has significantly increased since then, without these normative dimensions keeping pace.
Understanding the dimensions of standard parking spaces allows for anticipating maneuvering constraints, evaluating a real estate project, or simply avoiding scrapes in underground parking.

Underground Parking: Why Scrapes Increase Despite Standards
The NF P 91-100 and NF P 91-120 standards were written at a time when the most common vehicles measured less than 1.70 meters wide, excluding mirrors. SUVs and crossovers, which now represent a dominant share of sales, frequently exceed 1.85 meters in width, plus the mirrors.
With a space of 2.30 meters, the remaining margin on each side of the vehicle shrinks to just a few centimeters. Opening a door without touching the neighboring car is akin to a surgical maneuver, especially when a pillar or wall borders the spot.

Operators of underground parking lots are noticing a regular increase in minor accidents: door scratches, chips on bumpers, mirrors getting caught. The source of the problem is not driver inattention, but a structural mismatch between current vehicle sizes and fixed standards.
Some operators of newer parking facilities are intentionally widening spaces to 2.50 meters, or even 2.60 meters in high-turnover areas. This additional margin reduces accidents but decreases the total number of spaces, which poses a profitability issue per square meter.
Parking Space Dimensions According to Parking Type
Dimensions vary depending on the parking angle. Each configuration imposes a different circulation lane width, which alters the total area required per space.
Perpendicular Parking (90 Degrees)
The most common configuration in covered parking. The space measures 5 meters deep and 2.30 meters wide. The associated circulation lane must be at least 5 meters wide to allow for perpendicular maneuvers.
Angled Parking (45, 60, or 75 Degrees)
The angle reduces the required lane width and facilitates entry into the space. The dimensions of the spot remain similar (about 5 meters by 2.30 meters), but the circulation lane can drop to 3.50 meters for a 45-degree angle. This configuration optimizes space in elongated parking lots.
Parallel Parking (Longitudinal)
Used on the street, parallel parking requires longer spaces. The standard specifies a length of about 5 meters and a width of 2 meters on the roadway side. For street parking, the inter-ministerial instruction does not specify mandatory dimensions, except for spaces reserved for people with reduced mobility.
Parking Spaces with Obstacles or Walls
A lateral obstacle (pillar, wall, column) changes the situation. The standard provides for an increased width when one side of the space is bordered by a fixed element. This increased width compensates for the inability to open the door on the obstructed side.
- A wall or pillar on one side requires adding several tens of centimeters to the standard width
- An obstacle on both sides (space framed by two pillars) necessitates an even greater increase in width
- Spaces located at the end of a row, against a wall, are often the narrowest in practice, as the increased width is not always applied in older constructions
Checking for obstacles before renting or buying a space avoids unpleasant surprises. A space advertised at standard dimensions but wedged between two posts may turn out to be unusable for a wide vehicle.
Accessible Parking Spaces: Regulated Dimensions
Spaces reserved for people with reduced mobility follow distinct rules, outlined in the Construction and Housing Code. The minimum width is set at 3.30 meters, with a lateral circulation strip of at least 0.80 meters allowing for wheelchair passage.
Any parking lot larger than 500 square meters must include accessible spaces. Their signage (ground marking, vertical sign, pictogram) is mandatory and standardized. Non-compliance with these dimensions exposes the manager to administrative sanctions.
Dimensions of Parking Spaces for Electric Vehicles with Charging Stations
The installation of an IRVE charging station in a parking space requires additional space for the unit and the cable. The space itself retains the standard dimensions, but the station must remain accessible without obstructing door openings or encroaching on the circulation lane.
- The charging unit is typically mounted on an existing wall or post, which requires positioning the space in immediate proximity
- The cable must be able to reach the vehicle’s charging port without crossing a pedestrian passage area
- In condominiums, the installation falls under the right to plug-in, but the dimensions of the space do not change
The proliferation of charging stations in existing parking lots increases pressure on available space, especially when the spaces were not designed with this technical constraint in mind.
The gap between dimensional standards inherited from the 1990s and current vehicle sizes will not resolve itself. Recent construction projects are beginning to incorporate widths greater than the minimum regulatory requirement, but the existing parking stock remains sized for cars that no longer exist. When purchasing or renting a space, physically measuring the location with a tape measure remains the most reliable precaution.
