How Much Limestone Screenings for a 4x75 Walkway?
How much limestone screenings for a 4x75 walkway: at 3 inches deep you need about 2.78 cubic yards, which is roughly 3.9 tons at 1.4 tons per yard. The walkway covers 300 square feet, so every inch of depth adds about 0.93 yards.
Volume and tonnage calculator →The math for a 4x75 walkway
- Area: 4 × 75 = 300 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 300 × 0.250 = 75.0 cu ft.
- Cubic yards: ÷ 27 = 2.78 yd³.
- Tons: × 1.4 = 3.9 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 | 0.93 | 1.3 | 1.4 |
| 2 in | 1.85 | 2.6 | 2.9 |
| 3 in | 2.78 | 3.9 | 4.3 |
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. For foot traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 4.3 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.
Where limestone screenings fits
Good uses:
- 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 3 inches takes about 5.1 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
