A parallel parking space is widely accepted as approximately 9.1 feet wide by 20 feet long. However, many parallel parking spaces are bigger or smaller in comparison with these measurements.
The size of a parallel parking spot depends on multiple things, including the location of the car parked in front of and behind the desired spot. Sometimes a space can be very small and harder to parallel park, whereas other cars could leave more space, making it significantly easier to parallel park. Use caution while parallel parking in any-sized space to avoid injury or damage, paying special consideration to oncoming traffic and pedestrians.
