| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 3 in | 0.93 | 1.4 | 1.6 |
| 4 in | 1.23 | 1.9 | 2.1 |
| 6 in | 1.85 | 2.9 | 3.2 |

Working it out
- 100 sq ft × (6 ÷ 12) ft = 50.0 cubic feet.
- ÷ 27 = 1.85 cubic yards.
- × 1.55 tons per yard = 2.9 tons.
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. Typical weight: 1.5 to 1.7 compacted tons per cubic yard.
Before the truck comes
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose crusher run
Works well for:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Poor fit 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 12x24 area at 2 inches takes about 2.8 tons.
- Weight used here: about 1.55 tons per cubic yard.
Mistakes that throw off the order
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
