How to Calculate Gravel and Aggregate
Gravel is sold by volume and by weight, so it helps to know both. Start with the coverage area in square feet, then multiply by the depth in feet (inches divided by 12) to get cubic feet. Dividing cubic feet by 27 converts to cubic yards, the unit most bulk suppliers price by. The calculator also shows cubic meters for metric orders.
To convert volume to tons, multiply cubic yards by the material's density. Most gravel and crushed stone runs about 1.4 tons per cubic yard, but it varies with stone size and moisture — adjust the density field to match your supplier's figure. Enter a price per ton and you'll get an instant cost estimate for the whole job.
Frequently Asked Questions
How much gravel do I need?
Multiply the area in square feet by the depth in feet (inches ÷ 12) to get cubic feet, then divide by 27 for cubic yards. For example, 200 square feet at 3 inches deep is 50 cubic feet, or about 1.85 cubic yards.
How many tons of gravel in a cubic yard?
Most gravel and crushed stone weighs about 1.4 tons per cubic yard, though it ranges from roughly 1.3 to 1.5 tons depending on the material and moisture. This calculator uses an adjustable density so you can match your supplier.
How deep should a gravel base be?
For walkways and patios a 2–3 inch layer is usually enough, while driveways need 4–6 inches, often over a thicker compacted sub-base. Add depth for soft, clay, or poorly draining soils.
