| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 1 in | 0.31 | 0.4 | 0.5 |
| 2 in | 0.62 | 0.9 | 1.0 |
| 3 in | 0.93 | 1.3 | 1.4 |
Working it out
- 100 sq ft × (2 ÷ 12) ft = 16.7 cubic feet.
- ÷ 27 = 0.62 cubic yards.
- × 1.4 tons per yard = 0.9 tons.
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. Expect the weight to fall in the range of 1.3 to 1.5 tons per yard.
Getting the order right
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. This is small enough that bags may compete with a bulk minimum; price both.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose limestone screenings
Works well for:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Poor fit for:
- 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 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
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- 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.
