How this calculator works
Estimate gravel volume from the area to cover and the desired depth. The result is an estimate and may vary with the product, site conditions, measurement accuracy and installation method.
Before you use the estimate
- Measure the area carefully and keep units consistent.
- Review any waste allowance and material coverage assumptions.
- Check the product packaging or supplier specifications before purchasing.
Worked example
A 20 × 10 ft path, 3 in deep, with 5% waste: 20 × 10 × (3 ÷ 12) = 50 ft³ → ÷ 27 = 1.85 yd³ → × 1.05 = 1.94 yd³ (≈2.72 tons). Try these numbers in the calculator above to see each step.
Frequently asked questions
How much gravel do I need for a driveway?
Measure length × width × depth — 3 to 4 inches is typical for driveways — and enter them above. The calculator converts to cubic yards and tons.
How many tons are in a cubic yard of gravel?
Roughly 1.4 tons per cubic yard, depending on stone type and moisture. We use 1.4 as the standard estimate.
How deep should a gravel layer be?
2–3 inches for garden paths, 3–4 inches for driveways. A deeper base lasts longer but costs more.
