The length for angled or perpendicular types is 4.9 meters to 5.5 meters. This is 16 to 18 feet. The average width is 2.4 meters to 2.75 meters; this is equivalent to 7.9 feet to 9 feet. Variations on these figures range from 2.3 meters and 3.2 meters to 7.5 feet and 10 feet.
The standard width is 2.4 meters or 7.9 feet. The average length is 6.1 meters or 20 feet. These are typically marked 2.1 meters to 2.4 meters / 6.9 feet to 7.9 feet wide. The average length is 6.7 meters to 7.9 meters/ 22 feet to 26 feet. This is inclusive of the exit and entry maneuvering.
The measurements vary, but 130 sq ft / 12 sq m is just about the average. This area includes the portion set aside for circulation areas, parking, landscaping and end of aisle areas.

Parking that is adjoining the curb is typically 20 ft (6.1 m) long and 9.1 ft (2.7 m) wide. The parallel spaces are usually marked 6.9 to 7.7 ft (2.1 to 2.34 m) wide. The length is usually 22 to 26 ft (6.7 to 7.9 m). This is for exit and entry maneuvers.
In the US, the markings are set by the Manual of Uniform Traffic Control Devices (MUTCD). Besides the standard signs, local agencies may assign more curb markings. This may vary from state to state. In California, a white curb denotes passenger drop off or pick up.
The yellow curb is a sign for loading. The green curb indicates limited parking time. The blue curb is for disabled individuals that have the correct identification.
The red curb is meant for emergency vehicles. Parking, stopping and standing are not allowed. Again it may vary from state to state. In Florida and Oregon, no parking is indicated by the yellow curb. In Georgia, both yellow and red can be used as a no parking sign.
The parking space dimensions specified above are for the US and Canada. The specifications in Europe and the UK are usually smaller.
