Layout changes the total
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.
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
Lots need a cross slope, often around 1 to 2 percent, toward inlets or the edge. Plan striping, wheel stops and ADA spaces before paving so the layout works.
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.
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.
Getting an accurate area
Once you have a site plan, measure the paved outline rather than relying on a per-space estimate. Include the entrance apron, drive lanes, loading zones and any dumpster pad. Subtract islands and planting areas that will not be paved.
