How Much Does 23 Tons of #57 Stone Cover?
How much does 23 tons of #57 stone cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 23 tons is roughly 17.0 cubic yards. Spread 4 inches deep, that covers about 1,380 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 23 ÷ 1.35 = 17.0 yd³.
- Cubic yards to cubic feet: × 27 = 460 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 460 ÷ 0.333 = 1,380 sq ft.
Coverage of 23 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 2,760 | 307 |
| 3 in | 1,840 | 204 |
| 4 in | 1,380 | 153 |

About #57 stone
Since #57 is washed and open-graded, it moves a little underfoot. Many installers put it over a compacted base of a dense-graded stone rather than straight on soil. Weight runs about 1.3 to 1.45 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
What 23 tons looks like on site
For delivery, 23 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.

When to choose #57 stone
Best suited to:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Less suited to:
- A standalone base, since it does not pack hard without fines
- Paver setting beds
- Walk paths meant for strollers or wheelchairs
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 8x16 area at 2 inches takes about 1.1 tons.
- Weight used here: about 1.35 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
