How Much Crusher Run for a 24x40 Parking Pad?
A 24 by 40 foot parking pad is 960 square feet. How much crusher run for a 24x40 parking pad depends on depth: at 4 inches it is about 11.85 cubic yards or 18.4 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 24x40 parking pad
- Area: 24 × 40 = 960 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 960 × 0.333 = 320.0 cu ft.
- Cubic yards: ÷ 27 = 11.85 yd³.
- Tons: × 1.55 = 18.4 tons.
The volume and tonnage calculator does this for any size.
Crusher run needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

| 4 in | 11.85 | 18.4 | 20.2 |
| 6 in | 17.78 | 27.6 | 30.3 |
| 8 in | 23.70 | 36.7 | 40.4 |
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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
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. Since the parking pad carries parked vehicles, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 20.2 tons may take more than one 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
Poor fit for:
- 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 3 inches takes about 5.6 tons.
- Weight used here: about 1.55 tons per cubic yard.
Mistakes that throw off the order
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
