About this calculator

Overview

Sizing stone requirements is a balance between geometric volume and density. Whether you are ordering a truckload of crushed limestone for a sub-base or solid granite slabs for a patio, the material density dictates the logistics. This calculator converts your project area and depth into transportable weight, accounting for the natural density of common building stones.

Pro Tips

For gravel driveways, factor in 15% extra for 'Compaction' as the stone will be packed down by heavy equipment.
In metric regions, 1 cubic meter ($1m^3$) of solid granite weighs nearly 2.7 tonnes.
If calculating for a retaining wall, use the 'Solid' density; if calculating for backfill, use the 'Crushed' average.

Fun Facts

"A cubic yard of crushed stone typically weighs about 1.4 to 1.5 US tons (approx 2,800-3,000 lbs)."
"Basalt is one of the densest common stones used in construction, whereas sandstone is significantly lighter and more porous."
"Most regional quarries sell stone by the 'Ton' (US) or 'Metric Tonne' (International), rather than by volume."

Formula: Weight = (Area × Depth) × Density of Material
