How to Use This Calculator

How to Use

  1. Enter the length and width of the area.
  2. Enter the depth of crushed stone you want.
  3. Results show the volume plus the estimated weight to order.

Tips

  • Crushed stone weighs roughly 1.6 tonnes per cubic metre (about 1.35 tons per cubic yard).
  • Driveways usually need 100–150 mm (4–6 in); drainage trenches vary.
  • For irregular areas, split into rectangles and add the results.

Common Questions

How much does crushed stone weigh?

Crushed stone weighs about 1.6 tonnes per cubic metre, or roughly 1.35 tons per cubic yard, depending on the stone size.

How much crushed stone do I need?

Multiply length × width × depth to get the volume, then multiply by the density to get the weight. This calculator does both for you.

How deep should crushed stone be?

For driveways allow 100–150 mm (4–6 in). For a decorative top layer 50 mm (2 in) is usually enough over a compacted sub-base.
