How Much Crushed Stone for a 24x50 Parking Pad?
How much crushed stone for a 24x50 parking pad is a quick volume problem. 1,200 square feet at 4 inches comes to 14.81 cubic yards. Crushed stone usually weighs about 1.35 to 1.5 tons per cubic yard, so plan on roughly 20.7 tons.
Volume and tonnage calculator →The math for a 24x50 parking pad
- Area: 24 × 50 = 1,200 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 1,200 × 0.333 = 400.0 cu ft.
- Cubic yards: ÷ 27 = 14.81 yd³.
- Tons: × 1.4 = 20.7 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 | 7.41 | 10.4 | 11.4 |
| 3 in | 11.11 | 15.6 | 17.1 |
| 4 in | 14.81 | 20.7 | 22.8 |
| 6 in | 22.22 | 31.1 | 34.2 |
About crushed stone
Most quarries sell crushed stone by a size number or a screen size. Clean crushed stone drains well; stone with fines packs harder but sheds water more slowly. 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. 22.8 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.
Good and poor uses for crushed stone
Works well for:
- 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 15x30 area at 4 inches takes about 7.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
