How much limestone screenings for a 16x16 patio: at 3 inches deep you need about 2.37 cubic yards, which is roughly 3.3 tons at 1.4 tons per yard. The patio covers 256 square feet, so every inch of depth adds about 0.79 yards.
Volume and tonnage calculator →The math for a 16x16 patio
- Area: 16 × 16 = 256 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 256 × 0.250 = 64.0 cu ft.
- Cubic yards: ÷ 27 = 2.37 yd³.
- Tons: × 1.4 = 3.3 tons.

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. Weight per yard is a planning number; the scale ticket at the yard is the real one.
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. For foot traffic and furniture, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 3.7 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
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.
Common estimating mistakes
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- 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.
