Frequently Asked Questions

How much gravel do I need?

Multiply length × width × depth in the same units to get volume. This calculator does that and converts to tonnes based on typical gravel density.

What depth for a driveway?

Driveways often use 4–6 inches (10–15 cm) of compacted gravel. Check local practice and subbase requirements.

How many tonnes in a cubic metre of gravel?

Typically 1.4–1.7 tonnes per cubic metre depending on gravel type and compaction. The calculator uses an average; confirm with your supplier.
