How Much Does 19 Tons of #57 Stone Cover?
How much does 19 tons of #57 stone cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 19 tons is roughly 14.1 cubic yards. Spread 4 inches deep, that covers about 1,140 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: 19 ÷ 1.35 = 14.1 yd³.
- Cubic yards to cubic feet: × 27 = 380 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 380 ÷ 0.333 = 1,140 sq ft.
Coverage of 19 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 2,280 | 253 |
| 3 in | 1,520 | 169 |
| 4 in | 1,140 | 127 |

About #57 stone
#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself. 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.
Planning around 19 tons
19 tons will usually take two or more truck loads, though legal limits vary by truck and state. 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.
To run your own numbers, use the volume and tonnage calculator.
Where #57 stone fits
Best suited to:
- French drains and drainage layers
- The top course of a gravel driveway
- Under sheds where water needs to drain away
Think twice for:
- 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 10x20 area at 4 inches takes about 3.3 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- 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.
