About the Sand Calculator for Circles
Circular and curved landscaping features require a different calculation approach than rectangular areas. Our circular sand calculator uses the standard circle area formula — pi multiplied by radius squared — to accurately determine the volume of sand needed for round patios, circular garden beds, fire pit bases, round sandboxes, or any other circular project area. Accurately calculating sand for circular areas prevents under-ordering which causes project delays or over-ordering which wastes money. Enter the diameter or radius of your circular area and the required sand depth to instantly get results in cubic feet, cubic yards, and weight in tonnes and pounds.
