Why per-space area varies
Stall size, aisle width, one-way vs two-way traffic, angled vs 90-degree parking, islands and the entrance all change the area per space. Tight lots may run under 300 square feet per stall; lots with landscaping and wide aisles run well over 350. See parking spaces per acre.
Thickness and base
Light-duty lots commonly use a 2 to 3 inch surface on a compacted stone base; drive lanes and dumpster pads get heavier sections. Local code and soil conditions drive the final design. The asphalt base calculator sizes the stone layer.

Drainage and striping
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.
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.
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.
