The Stone Calculator estimates how much crushed stone, gravel, rock, or sand you need to cover an area — useful for landscaping, driveways, pathways, or garden beds. Enter your area's length, width, and depth (in any unit), then select your stone material to get the total stone needed in tons plus volume in cubic yards and cubic feet. Add an optional price per ton or cubic yard to see your estimated material cost.

To calculate stone needed, measure the length, width, and depth of your area. The calculator will convert these dimensions to cubic yards and then to tons based on the material density. Most landscaping projects need 2-4 inches of depth.
Yes, stone typically refers to larger rock fragments (2-6 inches), while gravel consists of smaller pieces (¾-2 inches). Crushed stone is even smaller (¼-2 inches). Each has different densities and uses in landscaping.
Stone can be purchased by either cubic yard or ton. Tons are more common for heavier materials like stone and gravel, while cubic yards are often used for lighter materials. Our calculator shows both measurements.
Crushed stone (¼-2 inches) is excellent for pathways and drainage. Gravel (¾-2 inches) works well for driveways and decorative areas. Larger rock and stone (2-6 inches) are ideal for drainage and erosion control.
The conversion depends on material density. Crushed stone typically weighs about 1.7 tons per cubic yard, while gravel ranges from 1.3-1.7 tons per cubic yard. Our calculator automatically handles these conversions.
Stone offers permanent coverage, excellent drainage, and low maintenance but doesn't improve soil. Mulch decomposes to enrich soil but requires regular replacement. Choose based on your project goals and maintenance preferences.
