How to use the Stone Calculator

Estimate landscape stone volume and approximate tonnage using editable density.

Calculation formula

Stone volume (yd³) = length × width × depth/12/27; weight (US tons) = volume × bulk density.

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations

Bulk densities vary by rock type, moisture and grading; vendor estimates may differ.
