Why per-space area varies
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.
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.

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.
Permits and planning
Before finalizing tons, confirm parking requirements, accessible space counts and drainage rules with the local jurisdiction. Stormwater rules in particular can change the layout or require inlets and detention.
Waste and yield
Paving crews usually order a bit more than the calculated tons to cover uneven base, handwork around edges and the last partial load. A few percent extra is common. Compaction also matters: tons are based on compacted density, not loose mix in the truck.
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.
