Bags of Limestone Screenings for a 8x16 Patio
How many bags of limestone screenings for a 8x16 patio: at 2 inches deep you need about 21.3 cubic feet, which is 43 bags of the common 0.5 cubic foot size. If your store sells limestone screenings in 50-pound bags instead, figure about 45 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 | 10.7 | 22 | 23 |
| 2 in | 21.3 | 43 | 45 |
| 3 in | 32.0 | 64 | 67 |
| 4 in | 42.7 | 86 | 89 |
How to figure it
- Area: 8 × 16 = 128 sq ft.
- Volume: 128 × (2 ÷ 12) = 21.3 cu ft.
- Bags: 21.3 ÷ 0.5 = 43 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 21.3 cubic feet is 0.79 yards, about 1.1 tons. This is a small enough job that bags are reasonable, especially if a bulk delivery fee applies. Compare the bag price × 43 against a bulk quote for 1.2 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.
Install tips for a patio
- 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.
When to choose limestone screenings
Works well for:
- 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 2 inches takes about 3.4 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
