Estimate gravel volume, weight, and cost
This gravel calculator estimates the volume (cubic feet and yards), weight in tons, and cost of gravel for rectangular or circular areas. Adjust the gravel density to match your specific material type, and optionally enter pricing to see estimated costs.
Common gravel densities range from 100–130 lbs per cubic foot. Pea gravel is typically around 110 lbs/cu ft, while crushed stone is about 120–130 lbs/cu ft.
A gravel driveway should have a depth of 4–6 inches of compacted gravel. For the base layer, use 4–6 inches of #3 or #4 crushed stone, topped with 2–3 inches of smaller gravel like #57 or #67 stone.
A ton of gravel typically covers about 60–80 sq ft at 4 inches deep, or 80–100 sq ft at 3 inches deep. Coverage depends on the gravel size, density, and compaction. Our calculator provides precise estimates based on your specific dimensions.
