How Much Does 29 Tons of Crushed Stone Cover?
How much does 29 tons of crushed stone cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 29 tons is roughly 20.7 cubic yards. Spread 4 inches deep, that covers about 1,678 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: 29 ÷ 1.4 = 20.7 yd³.
- Cubic yards to cubic feet: × 27 = 559 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 559 ÷ 0.333 = 1,678 sq ft.
Coverage of 29 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 3,356 | 373 |
| 3 in | 2,237 | 249 |
| 4 in | 1,678 | 186 |

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 29 tons looks like on site
29 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.

When to choose crushed stone
Works well for:
- 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 14x28 area at 3 inches takes about 5.1 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- 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.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
