Gravel Calculator
Free gravel calculator for driveways, paths, pads, drainage, and landscaping. Estimate project volume with ATHENA.
Plan gravel volume and a practical order quantity, then verify supplier-specific density and delivery information.
Plan the project with a practical estimate
For driveways, walkways, patios, drainage areas, and landscape beds, confirm the material type and supplier-specific density because weight per yard varies by product.
How much gravel do I need?
For a rectangular area, estimate cubic yards by multiplying length in feet × width in feet × depth in inches, then dividing by 324.
How do I calculate gravel in tons?
Start with the cubic-yard estimate, then use the bulk density for the specific gravel or aggregate you are buying. Density varies by material and moisture, so use the supplier's stated density for the final order.
How deep should gravel be?
The right depth depends on the project and material. Measure the finished design depth and account for compaction, grading, and waste when planning the order.
Enter the requested project inputs, review the result, and compare it with actual product specifications, site conditions, scope, supplier requirements, or business rules before making a final purchase or pricing decision.
ATHENA tools are designed to make common planning calculations faster and easier to check. Use the result as a starting point and keep the final decision tied to the real project requirements.
