How the gravel calculator works
Loose gravel typically weighs 1.4–1.7 tonnes per cubic metre depending on stone size and moisture.
Formula
tonnes = length × width × depth × bulk density
Worked example
A 10 × 3 m path at 5 cm needs 1.5 m³, about 2.4 tonnes.
Frequently asked questions
How deep should a driveway be?
Around 5 cm for a decorative path and 10 cm or more for a vehicle driveway.
