How Much Crushed Stone for a 10x50 Parking Pad?
How much crushed stone for a 10x50 parking pad is a quick volume problem. 500 square feet at 4 inches comes to 6.17 cubic yards. Crushed stone usually weighs about 1.35 to 1.5 tons per cubic yard, so plan on roughly 8.6 tons.
Volume and tonnage calculator →The math for a 10x50 parking pad
- Area: 10 × 50 = 500 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 500 × 0.333 = 166.7 cu ft.
- Cubic yards: ÷ 27 = 6.17 yd³.
- Tons: × 1.4 = 8.6 tons.
The volume and tonnage calculator does this for any size.
Crushed stone needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

| 2 in | 3.09 | 4.3 | 4.8 |
| 3 in | 4.63 | 6.5 | 7.1 |
| 4 in | 6.17 | 8.6 | 9.5 |
| 6 in | 9.26 | 13.0 | 14.3 |
About crushed stone
Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size. Weight per yard is a planning number; the scale ticket at the yard is the real one.
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. 9.5 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.
Good and poor uses for crushed stone
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Poor fit for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 14x28 area at 3 inches takes about 5.1 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
