Determine how much gravel, sand, or crushed stone you need by area and depth for your project.

Our free Gravel Calculator lets you determine how much gravel, sand, or crushed stone you need by area and depth for your project. It is built for contractors, DIY renovators, and homeowners planning building projects who need fast, reliable results without installing software or creating an account.

Gravel Calculator runs entirely in your browser on CalculatorsPlus — enter your values, get instant results, and copy or share your output in one click. Your data never leaves your device; we do not store inputs on any server.

Accurate material estimates prevent costly over-ordering and mid-project shortages. Measure carefully, add a waste factor for cuts and breakage, and use the gravel calculator output as a shopping list starting point.

Results update in real time as you change inputs, so you can explore "what if" scenarios — adjust one variable at a time to see how it affects the outcome before committing to a purchase, plan, or decision.

Frequently Asked Questions

How do I calculate gravel needed?
Volume = Length × Width × Depth. Then convert to tons: multiply cubic yards by 1.4 (typical gravel density) or cubic meters by 1,500 kg.
How much does gravel weigh?
Gravel weighs approximately 2,800 lbs per cubic yard (1.4 tons) or 1,500 kg per cubic meter. Exact weight varies by type and moisture content.
How deep should gravel be?
Driveways: 4–6 inches. Walkways: 2–3 inches. French drains: 12 inches. Garden paths: 2–4 inches. Deeper is better for high-traffic areas.
What size gravel should I use?
Base/foundation: 3/4" to 1.5" crushed stone. Walkways: 3/8" pea gravel. Driveways: 3/4" angular gravel. Drainage: 1"–2" river rock.
