Understanding Gravel Measurements

Gravel is typically sold by volume (cubic yards or cubic meters) or by weight (tons or tonnes). This calculator helps you convert your project dimensions into the amount of gravel needed.

Key Factors:

  • ⚖️
    Density

    Different gravel types have different densities, affecting the weight per volume.

  • 📏
    Depth

    Proper depth is crucial for stability and drainage in your project.

  • 🔄
    Compaction

    Gravel will compact over time, reducing the effective depth.

  • 💧
    Drainage

    Larger gravel sizes provide better drainage for water management.

Additional Considerations

  • Landscape Fabric:

    Consider installing landscape fabric beneath your gravel to prevent weed growth and keep the gravel from sinking into the soil.

  • Edging:

    Install edging around your gravel area to keep the material contained and maintain clean borders.

  • Compaction:

    For driveways and pathways, compact the gravel with a plate compactor for better stability and longevity.

  • Drainage:

    Ensure proper slope (about 1/4 inch per foot) away from buildings to prevent water pooling.
