How Much Does 3 Tons of Limestone Screenings Cover?
How much does 3 tons of limestone screenings 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 2 inches deep, that covers about 347 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: 3 ÷ 1.4 = 2.1 yd³.
- Cubic yards to cubic feet: × 27 = 58 cu ft.
- Divide by depth in feet: at 2 inches (0.167 ft), 58 ÷ 0.167 = 347 sq ft.
Coverage of 3 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 1 in | 694 | 77 |
| 2 in | 347 | 39 |
| 3 in | 231 | 26 |
About limestone screenings
Screenings hold moisture and can crust over. Use them in thin layers over a compacted stone base instead of as a thick layer on their own. Weight runs about 1.3 to 1.5 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Planning around 3 tons
For delivery, 3 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.
Good and poor uses for limestone screenings
Best suited to:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Less suited to:
- Deep layers on their own
- Low spots that collect water
- Under heavy vehicle traffic without a base
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of limestone screenings (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 20x25 area at 4 inches takes about 8.6 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
