Gravel Calculator
Estimate how much gravel you need for a driveway, patio base, walkway, or landscaping bed. Enter dimensions and depth, choose units, and the calculator will return volume and approximate weight in tons.
Inputs explained:
• Shape: rectangle/square, circle, or triangle.
• Dimensions: length & width (or diameter, or base & height).
• Depth: thickness of gravel layer (often 2–6 inches / 5–15 cm).
• Density: gravel varies, but ~1.35–1.55 tons per cubic yard is common. You can adjust it.
• Shape: rectangle/square, circle, or triangle.

• Depth: thickness of gravel layer (often 2–6 inches / 5–15 cm).
• Density: gravel varies, but ~1.35–1.55 tons per cubic yard is common. You can adjust it.
Typical: 2–6 inches.
Common range: ~1.35–1.55 tons/yd³ depending on gravel type and moisture.
Tip: For driveways, base layers may be thicker than top layers. Consider calculating each layer separately.
Gravel Calculator — Description
The Gravel Calculator helps you estimate how much gravel you need for landscaping, driveways, walkways, patios, and base layers. Enter the project shape (rectangle, circle, or triangle), dimensions, and gravel depth. The calculator returns total volume in cubic yards, cubic feet, and cubic meters, and estimates weight in tons using an adjustable gravel density.
To reduce the chance of running short, you can also add 5–10% overage for compaction, uneven ground, and spillage.
