How Much Limestone Screenings for a 3x50 Walkway?
How much limestone screenings for a 3x50 walkway: at 3 inches deep you need about 1.39 cubic yards, which is roughly 1.9 tons at 1.4 tons per yard. The walkway covers 150 square feet, so every inch of depth adds about 0.46 yards.
Volume and tonnage calculator →The math for a 3x50 walkway
- Area: 3 × 50 = 150 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 150 × 0.250 = 37.5 cu ft.
- Cubic yards: ÷ 27 = 1.39 yd³.
- Tons: × 1.4 = 1.9 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 | 0.46 | 0.6 | 0.7 |
| 2 in | 0.93 | 1.3 | 1.4 |
| 3 in | 1.39 | 1.9 | 2.1 |
About limestone screenings
Limestone screenings are the fine dust and chips left after crushing limestone. They pack very tight, which makes them a common setting bed for pavers and flagstone and a surface for paths. 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. This walkway sees foot traffic, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 2.1 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
Best suited to:
- 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 12x24 area at 3 inches takes about 3.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
