13 Cubic Yards of #57 Stone in Tons

13 cubic yards of #57 stone in tons works out to about 17.6 tons using a planning weight of 1.35 tons per yard. Real loads land between roughly 16.9 and 18.8 tons depending on stone size, fines and moisture. That is about 35,100 pounds.

The conversion

  • Yards × tons per yard: 13 × 1.35 = 17.6 tons.
  • Low end: 13 × 1.3 = 16.9 tons.
  • High end: 13 × 1.45 = 18.8 tons.

If your supplier quotes a different weight per yard, multiply by theirs.

About #57 stone

Since #57 is washed and open-graded, it moves a little underfoot. Many installers put it over a compacted base of a dense-graded stone rather than straight on soil.

Hauling 13 yards

Plan the delivery around 17.6 tons: two or more trucks in most areas. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.

Before you order

  • Confirm whether the yard prices #57 stone by the ton or by the yard.
  • Add about 10 percent for compaction and uneven ground.
  • Clear a firm spot for the truck to dump.

The volume and tonnage calculator converts any area and depth into yards and tons.

Good and poor uses for #57 stone

Good uses:

  • French drains and drainage layers
  • The top course of a gravel driveway
  • Under sheds where water needs to drain away

Poor fit for:

  • A standalone base, since it does not pack hard without fines
  • Paver setting beds
  • Walk paths meant for strollers or wheelchairs

Quick reference numbers

  • Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.2 tons.
  • Another size for comparison: a 10x20 area at 4 inches takes about 3.3 tons.
  • Weight used here: about 1.35 tons per cubic yard.

Mistakes that throw off the order

  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
