How Much Crusher Run for a 30x30 Parking Pad?
A 30 by 30 foot parking pad is 900 square feet. How much crusher run for a 30x30 parking pad depends on depth: at 4 inches it is about 11.11 cubic yards or 17.2 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 30x30 parking pad
- Area: 30 × 30 = 900 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 900 × 0.333 = 300.0 cu ft.
- Cubic yards: ÷ 27 = 11.11 yd³.
- Tons: × 1.55 = 17.2 tons.
The volume and tonnage calculator does this for any size.
Crusher run needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 8.33 | 12.9 | 14.2 |
| 4 in | 11.11 | 17.2 | 18.9 |
| 6 in | 16.67 | 25.8 | 28.4 |
| 8 in | 22.22 | 34.4 | 37.9 |
About crusher run
The fines in crusher run fill the gaps between stones, so it weighs more per yard than clean stone once compacted. Plan on rolling or plate-compacting it in lifts. 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. 18.9 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.
Where crusher run fits
Best suited to:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Think twice 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 20x25 area at 3 inches takes about 7.2 tons.
- Weight used here: about 1.55 tons per cubic yard.
Common estimating mistakes
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
