Landscape Rock Calculator

How to Use the Landscape Rock Calculator

To use this calculator, enter the length and width of the area in feet, and the depth in inches for the layer of rocks you want to calculate. Additionally, you can specify the density of the rock in pounds per cubic foot (the default value is 100 lb/ft³, which is typical for landscaping rocks). Click the “Calculate” button to get the result.

How It Calculates the Results

This calculator uses the formula to determine the volume in cubic feet and then converts that volume into pounds based on the density of the rock:

  • Volume (in cubic feet) = Length (ft) × Width (ft) × (Depth (in) / 12)
  • Weight (in pounds) = Volume (ft³) × Density (lb/ft³)

Limitations

This calculator assumes uniform and consistent rock coverage. The actual amount of rock needed may vary if the rock size or shape is inconsistent. Always consider buying a bit extra to account for inconsistencies and ensure you have enough material.
