What could these spaces earn? →A rough estimate for a flat, rectangular surface lot using common 9 × 18 ft spaces. Islands, curbs, entrances, landscaping and your local zoning rules will change the real number. Accessible spaces also need access aisles, which take a little more room.
Parking lot sizes, answered
Planning numbers only. Your city's zoning code and an engineer have the final say on a new or restriped lot.
How many parking spaces fit in an acre?+
Usually about 100 to 130 spaces with straight-in (90°) parking and two-way aisles, and fewer with angled parking. Islands, landscaping and entrances lower the number, so use the calculator with your lot's real shape.
How many square feet does one parking space take?+
A standard space is about 9 by 18 feet, or 162 square feet. Counting its share of the drive aisles, each car needs roughly 300 to 375 square feet of lot.
How wide should a parking lot drive aisle be?+
A common size is 24 feet for two-way traffic with 90° parking. One-way aisles for angled parking can be narrower, around 13 to 18 feet. Your local zoning code sets the exact sizes.
How many accessible parking spaces do I need?+
Under the 2010 ADA Standards, a lot with 1 to 25 spaces needs at least 1 accessible space, 26 to 50 needs 2, 51 to 75 needs 3 and 76 to 100 needs 4, rising from there. At least 1 in every 6 accessible spaces must be van-accessible.
Is 90° or angled parking better?+
Straight-in 90° parking fits the most cars and allows two-way traffic. Angled parking fits fewer cars but is easier to pull into, and it needs one-way aisles.
