Volume and tonnage calculator →Bag count by depth
| Depth | Cubic feet | 0.5 cu ft bags | 50 lb bags (approx.) |
|---|---|---|---|
| 1 in | 41.7 | 84 | 87 |
| 2 in | 83.3 | 167 | 173 |
| 3 in | 125.0 | 250 | 260 |
| 4 in | 166.7 | 334 | 346 |
How to figure it
- Area: 5 × 100 = 500 sq ft.
- Volume: 500 × (2 ÷ 12) = 83.3 cu ft.
- Bags: 83.3 ÷ 0.5 = 167 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 83.3 cubic feet is 3.09 yards, about 4.3 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 167 against a bulk quote for 4.8 tons delivered.
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.
Laying it down for a walkway
- Dig and level. Remove sod and set the base slightly below the surrounding grade.
- Edge it. Steel, plastic or stone edging keeps material in place.
- Spread in layers. Rake to depth, then tamp or wet and compact.
- Buy a few extra. Grab 5 to 10 percent more bags for settling and touch-ups.
The volume and tonnage calculator handles other sizes and depths.
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 14x28 area at 4 inches takes about 6.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- 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.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
