Gravel Calculator
Find out exactly how much gravel you need for your driveway, path, patio or landscaping project — in cubic yards, tons, pounds and bags.
1. Measure your area
2. Choose your gravel
Gravel density varies by material, moisture and supplier. Use your supplier's stated density when available. This calculator provides an estimate, not a supplier quote.

How much gravel do I need?
Start by measuring the length and width of the area you want to cover, then enter the depth of gravel you plan to install. Our calculator converts the resulting volume into cubic yards and estimates the weight in tons based on the selected gravel type.
How deep should gravel be?
For many landscaping applications, a depth of around 2–3 inches is common. Driveways and areas carrying vehicles may require a deeper, properly prepared base. Your local supplier or contractor can recommend the right depth for your project and soil conditions.
Why add a waste allowance?
Real projects rarely match the mathematical calculation perfectly. Edges, uneven ground, settling, compaction and small losses during installation can increase the amount needed. A 10% allowance is a useful starting point, but difficult or irregular areas may justify more.
How is gravel calculated?
For a rectangular area, volume is calculated as length × width × depth. The calculator converts that volume to cubic yards and then estimates weight using a typical bulk density for the selected material. Actual delivered weight can vary, so supplier specifications should take priority.
