Bags of Limestone Screenings for a 4x50 Walkway
How many bags of limestone screenings for a 4x50 walkway: at 2 inches deep you need about 33.3 cubic feet, which is 67 bags of the common 0.5 cubic foot size. If your store sells limestone screenings in 50-pound bags instead, figure about 70 bags, since limestone screenings weighs roughly 104 pounds per cubic foot.
Volume and tonnage calculator →Bag count by depth
| Depth | Cubic feet | 0.5 cu ft bags | 50 lb bags (approx.) |
|---|---|---|---|
| 1 in | 16.7 | 34 | 35 |
| 2 in | 33.3 | 67 | 70 |
| 3 in | 50.0 | 100 | 104 |
| 4 in | 66.7 | 134 | 139 |
How to figure it
- Area: 4 × 50 = 200 sq ft.
- Volume: 200 × (2 ÷ 12) = 33.3 cu ft.
- Bags: 33.3 ÷ 0.5 = 67 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 33.3 cubic feet is 1.23 yards, about 1.7 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 67 against a bulk quote for 1.9 tons delivered.
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.
Before you spread for a walkway
- Dig and level. Remove sod and set the base slightly below the surrounding grade.
- Edge it. Steel, plastic or stone edging keeps material in place.
- Spread in layers. Rake to depth, then tamp or wet and compact.
- Buy a few extra. Grab 5 to 10 percent more bags for settling and touch-ups.
The volume and tonnage calculator handles other sizes and depths.
Good and poor uses for limestone screenings
Best suited to:
- 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 2 inches takes about 3.4 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- 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.
