The math for a 14x40 parking pad

Area: 14 × 40 = 560 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 560 × 0.333 = 186.7 cu ft.
Cubic yards: ÷ 27 = 6.91 yd³.
Tons: × 1.55 = 10.7 tons.

The volume and tonnage calculator does this for any size.

About crusher run

Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the parking pad

Dig out organic soil, compact the subgrade and set an edge so the stone does not migrate onto the lawn. A pad that holds parked weight for long periods benefits from a dense base under the surface stone. This parking pad sees parked vehicles, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 11.8 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the parking pad as firm ground allows.

When to choose crusher run

Works well for:

Base under asphalt, pavers or concrete
Gravel drives that need a firm, packed surface
Shed pads and equipment pads

Less suited to:

Drainage layers, since the fines slow water
Decorative beds
Spots where you want water to soak straight through

Quick reference numbers

Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.8 tons.
Another size for comparison: a 14x28 area at 4 inches takes about 7.5 tons.
Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
