Gravel calculator
Enter your area and depth to estimate how much gravel to order. Add waste, density or bag size if you know them.
How much gravel do I need?
Choose a shape and unit, enter the measurements and depth, then calculate. The order volume includes your extra-material percentage. Weight and bag count appear when you enter density and bag size. Suppliers can use different densities, so treat the weight as an estimate.
