How Much Does 8 Tons of Crushed Stone Cover?
How much does 8 tons of crushed stone cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 8 tons is roughly 5.7 cubic yards. Spread 4 inches deep, that covers about 463 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 8 ÷ 1.4 = 5.7 yd³.
- Cubic yards to cubic feet: × 27 = 154 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 154 ÷ 0.333 = 463 sq ft.
Coverage of 8 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 926 | 103 |
| 3 in | 617 | 69 |
| 4 in | 463 | 51 |
| 6 in | 309 | 34 |
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 8 tons looks like on site
For delivery, 8 tons usually fits on one smaller dump 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
Good uses:
- 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 15x30 area at 3 inches takes about 5.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- 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.
