The Core Calculation
Stone quantity starts with volume: length × width × depth in metres. Convert to weight with material density, which varies by stone type and grading — always use the density your supplier confirms for the specific material rather than a generic figure.
The quantity calculator on this site handles the arithmetic and lets you switch between kilograms, tonnes and cubic metres.
Depths That Match Applications
Bed topping runs shallower than paths; paths need depth for compaction; dry creek beds follow the channel construction. Getting depth right per application matters more than precision on area.
Margins and Reality Checks
Add 10–20% for uneven ground, settling and site handling. Remember the result is a planning estimate, not a construction requirement — confirm final tonnage with the installer, and confirm the density figure with the supplier before ordering.
