How Much Does 9 Tons of Crusher Run Cover?
How much does 9 tons of crusher run cover depends on how deep you spread it. At about 1.55 tons per cubic yard, 9 tons is roughly 5.8 cubic yards. Spread 6 inches deep, that covers about 314 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 9 ÷ 1.55 = 5.8 yd³.
- Cubic yards to cubic feet: × 27 = 157 cu ft.
- Divide by depth in feet: at 6 inches (0.500 ft), 157 ÷ 0.500 = 314 sq ft.
Coverage of 9 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 627 | 70 |
| 4 in | 470 | 52 |
| 6 in | 314 | 35 |
| 8 in | 235 | 26 |
About crusher run
Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. 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 9 tons looks like on site
For delivery, 9 tons is in the range of one full tandem load. 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.

Where crusher run fits
Good uses:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Think twice 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 8x16 area at 4 inches takes about 2.4 tons.
- Weight used here: about 1.55 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
