A free online gravel calculator for landscaping, driveway, and construction projects. Enter your project dimensions, choose your gravel type, and instantly calculate how much material you need. Supports both metric and imperial units. All calculations happen in your browser — no data is sent to any server.
Calculate the volume of your project area (Length × Width × Depth), then multiply by the density of your chosen gravel type. Add a waste factor (typically 10%) to account for compaction and spillage.
The waste factor accounts for compaction, spillage, and irregular shapes. A 10% waste factor is recommended for most projects. Tight, well-measured projects may use 5%, while complex shapes may need 15%.
Pea Gravel is best for paths and decorative areas. Crushed Stone is ideal for driveways and patios due to its compaction. River Rock is great for drainage and landscaping. Marble Chips are perfect for decorative garden paths.
Simply select your preferred unit system in the calculator. The tool handles all conversions automatically. 1 meter = 3.281 feet, 1 foot = 30.48 centimeters.
