How Much Does 30 Tons of Crusher Run Cover?
How much does 30 tons of crusher run cover depends on how deep you spread it. At about 1.55 tons per cubic yard, 30 tons is roughly 19.4 cubic yards. Spread 6 inches deep, that covers about 1,045 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 30 ÷ 1.55 = 19.4 yd³.
- Cubic yards to cubic feet: × 27 = 523 cu ft.
- Divide by depth in feet: at 6 inches (0.500 ft), 523 ÷ 0.500 = 1,045 sq ft.
Coverage of 30 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 2,090 | 232 |
| 4 in | 1,568 | 174 |
| 6 in | 1,045 | 116 |
| 8 in | 784 | 87 |
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. Weight runs about 1.5 to 1.7 compacted tons per cubic yard, so treat the table as a planning range rather than an exact figure.
What 30 tons looks like on site
For delivery, 30 tons means multiple trips or a larger truck. Ask the supplier how they will split it. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.

Good and poor uses for crusher run
Best suited to:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Less suited to:
- 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 20x25 area at 3 inches takes about 7.2 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
