How Many Tons of Gravel Do I Need?
Measure length × width × depth in feet (depth in inches ÷ 12). Divide cubic feet by 27 = cubic yards. Multiply by material density: Crushed limestone: 1.4 tons/cy, Pea gravel: 1.4, River rock: 1.5. Add 5% for compaction.
How Much Does Gravel Cost?
Crushed stone: $25–$50/ton depending on type. Delivery: $50–$100 per load. A 50×12ft driveway at 4" deep needs ~4.7 tons ≈ $120–$235 + delivery.
