A parking space is a location that is designated for parking. This can be in a parking garage or in a parking lot or on a city street. It is usually designated by a white-paint-on-tar rectangle. The automobile fits inside the space, either by parallel parking, perpendicular parking or angle parking. The typical small or compact stall is about 275 square feet (25 m2;), while the average stall is about 325 square feet (30 m2;). Note that this area includes the area for parking stall plus the circulation areas, end of aisle areas/landscaping. Common angled or perpendicular parking stalls are 8 to 9 feet (2.4-2.75 m) wide by 16 to 18 feet (4.9-5.5 m) long. Some spaces can be as narrow as 7.5 feet and as wide as 10 feet. The choice of specific parking dimensions depends upon the function of the parking - the greater the use of the space (high turnover) and/or more retail customer in nature - the larger dimensions are commonly utilized. Many parking spaces contain a turtarrier which is used to prevent cars from pulling too far into the space.
