How much gravel do I need?
yd³ = L (ft) × W (ft) × depth (ft) ÷ 27
tons = yd³ × density (tons per yd³)
Gravel weighs roughly 1.3–1.5 US tons per cubic yard depending on stone size, type and moisture, so the default 1.4 is an estimate. Suppliers sell by the ton or yard; ask for their figure. Typical depths: about 2–3 in for paths and 4–6 in for driveways, often over a compacted base. Order 5–10% extra for compaction and uneven ground.
