How Much Limestone Screenings for a 6x75 Walkway?
A 6 by 75 foot walkway is 450 square feet. How much limestone screenings for a 6x75 walkway depends on depth: at 3 inches it is about 4.17 cubic yards or 5.8 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 6x75 walkway
- Area: 6 × 75 = 450 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 450 × 0.250 = 112.5 cu ft.
- Cubic yards: ÷ 27 = 4.17 yd³.
- Tons: × 1.4 = 5.8 tons.
The volume and tonnage calculator does this for any size.
Limestone screenings needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 1.39 | 1.9 | 2.1 |
| 2 in | 2.78 | 3.9 | 4.3 |
| 3 in | 4.17 | 5.8 | 6.4 |
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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the walkway
Dig the path a few inches below grade, compact the bottom, add fabric if needed and install edging on both sides so the material stays on the walk. Since the walkway carries foot traffic, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 6.4 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the walkway as firm ground allows.
Good and poor uses for limestone screenings
Good uses:
- Paver and flagstone setting beds
- Firm walking paths
- Top-dressing a compacted stone base
Think twice 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 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
