How to figure it

  1. Area: 14 × 16 = 224 sq ft.
  2. Volume: 224 × (2 ÷ 12) = 37.3 cu ft.
  3. Bags: 37.3 ÷ 0.5 = 75 bags (round up).

Bags or bulk?

A cubic yard is 27 cubic feet, so 37.3 cubic feet is 1.38 yards, about 1.9 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 75 against a bulk quote for 2.1 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 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.

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 8x16 area at 3 inches takes about 1.7 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
