Layout changes the total
The 325 square feet per stall figure is a planning number. Ninety-degree parking with two-way aisles, ADA spaces, islands and driveways push it up. Measure the actual paved outline once a site plan exists. See parking spaces per acre.
Section design
Car-only lots are often paved with 2 to 3 inches of asphalt over 6 to 8 inches of compacted aggregate base. Areas with trucks, buses or dumpsters need a thicker section. An engineer or local spec usually sets the design for commercial lots. The asphalt base calculator sizes the stone layer.

Finishing the lot
Grade the lot to drain and lay out striping, ADA access and wheel stops in advance. Seal coating a year or so after paving helps protect the surface.
Waste and yield
Hand work around islands, curbs and drains uses more material than machine paving across open areas. Many estimators add a few percent to the computed tons, then adjust with the paving crew based on the base grade.
Permits and planning
Commercial lots are often subject to local zoning rules on the number of spaces, ADA stalls, landscaping and stormwater. Check with the local planning office early, since requirements can change the paved area.
Getting an accurate area
A surveyor’s plan or a scaled site drawing gives the most accurate paved area. Break the lot into rectangles for parking rows and aisles, add the entrance and any extra pads, and then convert to tons at the design thickness.
