How Much Limestone Screenings for a 8x24 Patio?
How much limestone screenings for a 8x24 patio: at 3 inches deep you need about 1.78 cubic yards, which is roughly 2.5 tons at 1.4 tons per yard. The patio covers 192 square feet, so every inch of depth adds about 0.59 yards.
Volume and tonnage calculator →The math for a 8x24 patio
- Area: 8 × 24 = 192 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 192 × 0.250 = 48.0 cu ft.
- Cubic yards: ÷ 27 = 1.78 yd³.
- Tons: × 1.4 = 2.5 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 | 0.59 | 0.8 | 0.9 |
| 2 in | 1.19 | 1.7 | 1.8 |
| 3 in | 1.78 | 2.5 | 2.7 |
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 patio
Remove sod, level the area with a slight slope away from the house, and lay landscape fabric if weeds are a concern. Edging keeps loose material inside the patio footprint. This patio sees foot traffic and furniture, 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. 2.7 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 patio as firm ground allows.
Good and poor uses for 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 10x20 area at 4 inches takes about 3.5 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
