How this calculator works
Volume in cubic feet = square footage × depth in inches ÷ 12. Divide by 27 for cubic yards, then apply the selected waste percentage. Weight = required cubic feet × supplied bulk density ÷ 2,000. Density and compaction vary; verify quantities with your supplier.
Use current quotes, local rates, and measured dimensions to make this estimate useful for your situation.
Frequently asked questions
How many cubic yards of gravel do I need?+
Multiply area in square feet by depth in inches, then divide by 324. Include an allowance for losses if needed.
How accurate is the weight estimate?+
Density depends on moisture, stone type, and compaction. Use a supplier-specified density and confirm their ton definition.
