How Much Crushed Stone for a 14x36 Parking Pad?
A 14 by 36 foot parking pad is 504 square feet. How much crushed stone for a 14x36 parking pad depends on depth: at 4 inches it is about 6.22 cubic yards or 8.7 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 14x36 parking pad
- Area: 14 × 36 = 504 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 504 × 0.333 = 168.0 cu ft.
- Cubic yards: ÷ 27 = 6.22 yd³.
- Tons: × 1.4 = 8.7 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 | 3.11 | 4.4 | 4.8 |
| 3 in | 4.67 | 6.5 | 7.2 |
| 4 in | 6.22 | 8.7 | 9.6 |
| 6 in | 9.33 | 13.1 | 14.4 |
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. 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. 9.6 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.
Where crushed stone fits
Good uses:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Less suited to:
- 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
