Gravel Calculator
Calculate exactly how much gravel or crushed stone you need for a driveway, path, or base layer — in cubic yards and tons, adjustable for material density.

Enter area and depth to calculate gravel needed

About the Gravel Calculator
Gravel and crushed stone are typically sold by weight (tons) even though you plan the job by volume (area × depth). This calculator bridges the two, converting your area and depth into both cubic yards and the tons you’ll need to order.
Why Density Matters
Different materials pack to different densities — pea gravel is lighter per cubic yard than crushed stone or river rock. Using the wrong density assumption can leave you short or with excess material, so this tool lets you select your specific material type.
Typical Depths
A gravel driveway base layer is usually 4-6 inches deep, while a decorative walking path or top-dressing layer is often just 2 inches.
