Working it out

  1. 1,000 sq ft × (4 ÷ 12) ft = 333.3 cubic feet.
  2. ÷ 27 = 12.35 cubic yards.
  3. × 1.4 tons per yard = 17.3 tons.

About crushed stone

Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size. Typical weight: 1.35 to 1.5 tons per cubic yard.

Before the truck comes

  • Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
  • Add a margin. About 10 percent covers compaction and low spots.
  • Bulk or bags. Bulk delivery is the practical choice here.
  • Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.

Use the volume and tonnage calculator for any other size.

Where crushed stone fits

Best suited to:

  • Driveway top courses and parking pads
  • Shed and hot tub bases
  • Backfill behind walls when a clean size is used

Think twice for:

  • Barefoot areas, since angular stone is rough
  • Play areas
  • Places that need a smooth rolling surface for wheels

Quick reference numbers

  • Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.3 tons.
  • Another size for comparison: a 12x24 area at 4 inches takes about 5.0 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.
  • 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.
