How Much Does 3 Tons of Crushed Stone Cover?
How much does 3 tons of crushed stone cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 3 tons is roughly 2.1 cubic yards. Spread 4 inches deep, that covers about 174 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 3 ÷ 1.4 = 2.1 yd³.
- Cubic yards to cubic feet: × 27 = 58 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 58 ÷ 0.333 = 174 sq ft.
Coverage of 3 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 347 | 39 |
| 3 in | 231 | 26 |
| 4 in | 174 | 19 |
| 6 in | 116 | 13 |
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.
What 3 tons looks like on site
3 tons is a light load that a single-axle dump truck can often handle, 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.
When to choose crushed stone
Good uses:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Think twice 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
