Gravel Coverage Calculator | Accurate Area & Depth Calculation

This gravel coverage calculator tool helps you determine how much gravel you need for your project.






How to Use the Gravel Coverage Calculator

This calculator helps you estimate the amount of gravel needed to cover a specific area. To use the calculator, follow these steps:

  1. Enter the length of the area in feet.
  2. Enter the width of the area in feet.
  3. Enter the depth of gravel in inches.
  4. Enter the density of the gravel in pounds per cubic foot (the default value is 100 lbs/ft³).
  5. Click the “Calculate” button.
  6. The result displayed is the estimated amount of gravel needed in tons.

Explanation of How the Calculator Works

The gravel coverage calculator works by calculating the volume of the area to be covered, then converting this volume to weight using the density of the gravel, and finally converting the weight to tons.

Here is a step-by-step breakdown of the calculation:

  1. Volume (cubic feet) = Length (feet) * Width (feet) * Depth (inches) / 12
  2. Weight (pounds) = Volume (cubic feet) * Density (lbs/ft³)
  3. Weight (tons) = Weight (pounds) / 2000

Limitations of the Calculator

Please note the following limitations when using this calculator:

  • The calculator assumes a uniform thickness of gravel across the entire area.
  • The density of gravel can vary depending on the type and source of the material. The default density value of 100 lbs/ft³ is an average approximation; for more accurate results, use the specific density of your gravel.
  • Results are estimates and may need adjustment based on actual field conditions.
