How Much Limestone Screenings for a 5x100 Walkway?
A 5 by 100 foot walkway is 500 square feet. How much limestone screenings for a 5x100 walkway depends on depth: at 3 inches it is about 4.63 cubic yards or 6.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 5x100 walkway
- Area: 5 × 100 = 500 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 500 × 0.250 = 125.0 cu ft.
- Cubic yards: ÷ 27 = 4.63 yd³.
- Tons: × 1.4 = 6.5 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 | 1.54 | 2.2 | 2.4 |
| 2 in | 3.09 | 4.3 | 4.8 |
| 3 in | 4.63 | 6.5 | 7.1 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
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. 7.1 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
Less suited to:
- 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
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
