How Much Does 30 Tons of Crushed Stone Cover?
How much does 30 tons of crushed stone cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 30 tons is roughly 21.4 cubic yards. Spread 4 inches deep, that covers about 1,736 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: 30 ÷ 1.4 = 21.4 yd³.
- Cubic yards to cubic feet: × 27 = 579 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 579 ÷ 0.333 = 1,736 sq ft.
Coverage of 30 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 3,471 | 386 |
| 3 in | 2,314 | 257 |
| 4 in | 1,736 | 193 |
| 6 in | 1,157 | 129 |
About crushed stone
Most quarries sell crushed stone by a size number or a screen size. Clean crushed stone drains well; stone with fines packs harder but sheds water more slowly. Weight runs about 1.35 to 1.5 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Putting 30 tons to use
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.
To run your own numbers, use the volume and tonnage calculator.
When to choose crushed stone
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Poor fit for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 8x16 area at 4 inches takes about 2.2 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
