How to use the Gravel Calculator

  2. Press Calculate Gravel.

Formula and method

Volume (cubic feet) = length × width × depth in feet. Divide by 27 for cubic yards.

Worked example

A 20 ft × 10 ft area at 3 inches deep needs 50 cubic feet, or 1.85 cubic yards.

Tips

  • Order a little extra because gravel compacts.
