When designing a parking garage for new developments, some basic components are considered industry standards. The average size of a parking space in an enclosed garage is 10’ X 20’. That’s about 200 square feet per space. The drive aisle is 20’-24’ wide. Parking spaces adjacent to walls, elevators, stairs etc. should be widened by one foot so the vehicle doors can be easily opened. As a rule of thumb, the average conventional parking space dimension would be 300-350 Sqf.
User comfort is a major consideration. Providing users with maximum maneuvering ability “pays” in space. 90-degree parking might be economical to the land use, but for drivers it is the most difficult to maneuver. Angled parking is less efficient with the number of stalls and requires one-way traffic.
To developers, the meaning of using conventional parking is allocating more volume to non-revenue-generating space.
