The math for a 12x16 patio

  1. Area: 12 × 16 = 192 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 192 × 0.250 = 48.0 cu ft.
  4. Cubic yards: ÷ 27 = 1.78 yd³.
  5. Tons: × 1.55 = 2.8 tons.

About crusher run

Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

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. 3.0 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 crusher run

Best suited to:

  • Base under asphalt, pavers or concrete
  • Gravel drives that need a firm, packed surface
  • Shed pads and equipment pads

Less suited to:

  • Drainage layers, since the fines slow water
  • Decorative beds
  • Spots where you want water to soak straight through

Quick reference numbers

  • Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.8 tons.
  • Another size for comparison: a 20x25 area at 3 inches takes about 7.2 tons.
  • Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
