Bags of Limestone Screenings for a 5x50 Walkway
How many bags of limestone screenings for a 5x50 walkway: at 2 inches deep you need about 41.7 cubic feet, which is 84 bags of the common 0.5 cubic foot size. If your store sells limestone screenings in 50-pound bags instead, figure about 87 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 | 20.8 | 42 | 44 |
| 2 in | 41.7 | 84 | 87 |
| 3 in | 62.5 | 125 | 130 |
| 4 in | 83.3 | 167 | 173 |
How to figure it
- Area: 5 × 50 = 250 sq ft.
- Volume: 250 × (2 ÷ 12) = 41.7 cu ft.
- Bags: 41.7 ÷ 0.5 = 84 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 41.7 cubic feet is 1.54 yards, about 2.2 tons. At this size, a bulk delivery usually beats a cart full of bags once you count trips. Compare the bag price × 84 against a bulk quote for 2.4 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.
Laying it down 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
Works well for:
- 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 15x30 area at 4 inches takes about 7.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
