How Much Limestone Screenings for a 4x50 Walkway?
How much limestone screenings for a 4x50 walkway: at 3 inches deep you need about 1.85 cubic yards, which is roughly 2.6 tons at 1.4 tons per yard. The walkway covers 200 square feet, so every inch of depth adds about 0.62 yards.
Volume and tonnage calculator →The math for a 4x50 walkway
- Area: 4 × 50 = 200 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 200 × 0.250 = 50.0 cu ft.
- Cubic yards: ÷ 27 = 1.85 yd³.
- Tons: × 1.4 = 2.6 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 | 0.62 | 0.9 | 1.0 |
| 2 in | 1.23 | 1.7 | 1.9 |
| 3 in | 1.85 | 2.6 | 2.9 |
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 per yard is a planning number; the scale ticket at the yard is the real one.
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. 2.9 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.
When to choose 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
