Calculating gravel by weight
Gravel is usually sold by weight. First find the volume (length × width × depth), then multiply by density. Most decorative gravel and crushed stone weighs about 1.5–1.7 tonnes per cubic metre; this calculator uses 1.6.
For driveways, lay gravel on a compacted sub-base and use angular stone (e.g. 20 mm) that locks together rather than rounded pea gravel.
