What Is a Gravel Calculator?
A gravel calculator is a tool that helps you determine the amount of aggregate material (like gravel, sand, or crushed stone) you need for projects like driveway bases, paver patio foundations, or landscaping beds. It provides the required volume and estimated weight, helping you order the correct amount from a supplier without over- or under-buying. This free tool simplifies project planning and budgeting.

How to Use This Calculator
Our free gravel calculator gives you instant material estimates. Follow these steps:
- Select Material Type: Choose the material you are using (Gravel, Sand, or Crushed Stone).
- Enter Area Dimensions: Input the length and width of your project area.
- Set Material Depth: Input the desired thickness of the material layer in inches.
- Add Cost (Optional): Enter the cost per ton or cubic yard for a budget estimate.
- Click "Calculate": Get your estimated material volume and weight instantly.
Understanding Your Material Estimate
This calculator provides two key measurements to help you order from a landscape supplier.
- Volume (Cubic Yards/Meters): This is the total volume of space your project area occupies. It's the primary measurement used for ordering bulk materials. One cubic yard is a 3ft x 3ft x 3ft cube.
- Weight (Tons/Tonnes): This is an *estimated* weight of the material based on standard densities. This is useful because many suppliers sell materials by weight (tons) rather than by volume.
A properly installed 4-6 inch compacted gravel base is the single most important factor for a long-lasting paver patio or driveway, preventing sinking and cracking.
Example Gravel Calculation
Here is a common scenario for calculating the base material for a new driveway.
| Input | Example Value |
|---|---|
| Material Type | Crushed Stone |
| Area Dimensions (LxW) | 50 ft x 10 ft |
| Depth | 6 inches |
| Estimated Volume | ~9.3 cu yd |
| Estimated Weight | ~13.4 tons |
