Frequently Asked Questions
Everything you need to know about our gravel calculator
How do I calculate gravel needed?
Volume = L × W × D in feet, divide by 27 for cubic yards
Volume = Length × Width × Depth. Convert to cubic yards by dividing cubic feet by 27. For tons, multiply cubic yards by the material density (gravel ≈ 1.4 tons/cubic yard).
How much gravel for a driveway?
10x50 ft driveway at 4" depth ≈ 6 cubic yards / 8-9 tons
Standard depth is 4-6 inches. A 12x60 ft driveway at 4 inches deep needs: (12×60×0.33)/27 = 8.8 cubic yards, about 12-13 tons.
How many tons in a cubic yard of gravel?
~1.4 tons per cubic yard (varies by type)
Approximately 1.4 tons per cubic yard for most gravel. Varies by type: pea gravel ~1.3, crushed stone ~1.4, river rock ~1.5 tons per cubic yard.
