Typical materials for a gravel project
Tonnage depends on stone type and compaction. Verify depth requirements for your use case.
Gravel coverage depends on area, depth, and stone density. Suppliers often sell by the ton, so we convert cubic yards using your density assumption.
Results are planning estimates based on typical assumptions. Verify quantities with product labels and your project layout before purchase. How we calculate
A 20×10 driveway at 3 inches deep needs about 1.85 cubic yards or roughly 2.6 tons at standard density. Depth of 4–6 inches is common for driveways — adjust depth in the calculator.
Walkways and patios often use 2–3 inches. Driveways typically need 4–6 inches over a compacted base. Heavier traffic requires greater depth.
It depends on stone type. Most crushed stone weighs about 1.4 tons per cubic yard. Dense river rock can be heavier. The calculator uses your density assumption.
Add 10% for compaction, spillage, and uneven spread. Gravel settles after installation, so a slightly generous order prevents mid-project shortages.
Yes, for driveways and high-traffic areas. A compacted base layer improves drainage and prevents sinking. This calculator estimates top gravel volume only.
Yes. Adjust the density value to match your material. Lighter decorative gravel may be closer to 1.2 tons per cubic yard; heavier stone may exceed 1.5.
