How Much Does 35 Tons of #57 Stone Cover?
How much does 35 tons of #57 stone cover depends on how deep you spread it. At about 1.35 tons per cubic yard, 35 tons is roughly 25.9 cubic yards. Spread 4 inches deep, that covers about 2,100 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 35 ÷ 1.35 = 25.9 yd³.
- Cubic yards to cubic feet: × 27 = 700 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 700 ÷ 0.333 = 2,100 sq ft.
Coverage of 35 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 4,200 | 467 |
| 3 in | 2,800 | 311 |
| 4 in | 2,100 | 233 |
| 6 in | 1,400 | 156 |
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 35 tons
35 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.

Good and poor uses for #57 stone
Good uses:
- 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 12x24 area at 3 inches takes about 3.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- 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.
