Gravel Driveway Calculator
Enter your driveway's length, width and gravel depth. Residential gravel driveways are usually 4–6 inches total, often in two layers. The calculator returns cubic yards and tons so you can order by weight.

The formula
Tons = (Length ft × Width ft × (Depth in ÷ 12) ÷ 27) × 1.4 tons/yd³
Example: A 50 ft × 12 ft driveway at 4 in deep = 7.41 yd³ ≈ 10.4 tons of gravel.
How it works
- 1Calculate the volume in cubic yards (area × depth ÷ 27).
- 2Multiply by ~1.4 to convert cubic yards to tons for driveway gravel.
- 3Suppliers usually sell by the ton, so order by weight.
Frequently asked questions
How many inches of gravel do I need for a driveway?
Plan for 4–6 inches total on a stable sub-grade, ideally as two layers: a coarse base (such as crusher run) topped with a finer driving surface. Soft or clay soils need more depth and a geotextile fabric underneath.
