Tons of Crushed Stone per 100 Feet of 16 ft Road
Tons of crushed stone per 100 feet of 16 foot road: about 28 tons at 4 inches deep. The strip is 16 ft × 100 ft = 1,600 square feet. Long runs magnify small depth changes, so pin the depth down before ordering.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 21 | 2 |
| 4 in | 28 | 2 |
| 6 in | 41 | 3 |
| 8 in | 55 | 4 |
The math
- Area: 16 × 100 = 1,600 sq ft.
- Volume at 4 in: 1,600 × 0.333 = 533 cu ft (20 cubic yards).
- × 1.4 tons per yard = 28 tons.
Road section basics
At 16 feet wide, two cars can meet with care. 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. Crown the surface so water sheds to ditches on both sides.
Practical notes
- Phasing. Large tonnages are delivered over days; schedule spreading and compaction to keep up with trucks.
- Waste. Allow 5 to 10 percent.
- Hauling. Distance from the quarry or plant often costs as much as the material on long jobs; see asphalt hauling cost per ton.

Where crushed stone fits
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 20x25 area at 3 inches takes about 6.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons 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.
