How much gravel do I need?

Length × width × depth (in feet) gives cubic feet; divide by 27 for cubic yards. Crushed gravel weighs roughly 1.4 tons per cubic yard. Typical depths: 2–3 in for a top dressing, 4 in for walkways, 6–8 in (in compacted lifts) for new driveways. Add ~5% for compaction and settling — this calculator includes it.
