Dirt Yardage Calculator

Dirt Yardage Calculator

When planning a landscaping, gardening, or construction project, one of the biggest challenges is estimating how much dirt or soil you need. Ordering too little can delay your project, while ordering too much can waste money. This is where a dirt yardage calculator becomes essential.

A dirt yardage calculator is a practical online tool that helps you quickly determine the amount of dirt required for a specific area, taking into account the dimensions of the space and the soil type. By entering a few key measurements, you can calculate the cubic feet, cubic yards, and even make adjustments for soil density or compaction.

This guide explains how to use the calculator effectively, provides examples, and offers tips to get the most accurate results.

What is a Dirt Yardage Calculator?

A dirt yardage calculator is an online tool that calculates the volume of dirt or soil required for a project. It uses basic measurements such as:

  • Length (ft) of the area to be filled
  • Width (ft) of the area
  • Depth (inches) of the soil layer
  • Soil Type Adjustment (%) to account for compaction or loose soil

Once these inputs are entered, the calculator computes:

  • Cubic Feet Required: The total volume in cubic feet
  • Cubic Yards Required: The volume converted to cubic yards (the standard unit for soil delivery)
  • Adjusted Yardage: Volume adjusted for soil type or compaction

Using a calculator like this ensures accurate ordering, reducing both project delays and costs.

Benefits of Using a Dirt Yardage Calculator

  1. Accurate Estimation: Quickly calculate the exact amount of dirt needed.
  2. Saves Money: Prevent over-ordering and reduce waste.
  3. Time-Saving: No need for manual calculations; results are instant.
  4. Soil Type Consideration: Adjust for soil compaction, moisture, or density.
  5. Project Planning: Helps determine delivery requirements and budget.
  6. User-Friendly: Requires only basic project measurements.

How to Use the Dirt Yardage Calculator

Using the calculator is straightforward:

  1. Enter Length:
    Input the length of the area in feet. This is usually the longer side of the space to be filled.
  2. Enter Width:
    Input the width of the area in feet.
  3. Enter Depth:
    Provide the depth in inches. Remember, 12 inches equals 1 foot.
  4. Enter Soil Type Adjustment (Optional):
    Some soils compact more than others. Enter a percentage to adjust for soil density. For example, clay may need an extra 10% to account for settling.
  5. Click Calculate:
    The calculator will display:
    • Cubic Feet Required – The total volume in cubic feet.
    • Cubic Yards Required – Converts cubic feet to cubic yards (1 cubic yard = 27 cubic feet).
    • Adjusted Yardage – Volume adjusted for soil type percentage.
  6. Reset for New Calculations:

Example Calculation

Scenario: You are filling a garden bed that measures 20 ft in length, 10 ft in width, and 6 inches in depth. The soil type adjustment is 5% to account for compaction.

Calculation Steps:

  1. Convert depth to feet: 6 inches ÷ 12 = 0.5 ft
  2. Calculate cubic feet: 20 × 10 × 0.5 = 100 ft³
  3. Convert to cubic yards: 100 ÷ 27 ≈ 3.70 yd³
  4. Adjust for soil type: 3.70 × 1.05 ≈ 3.89 yd³

Result:

  • Cubic Feet Required: 100 ft³
  • Cubic Yards Required: 3.70 yd³
  • Adjusted Yardage: 3.89 yd³

This tells you to order about 3.9 cubic yards of dirt to ensure full coverage with soil adjustment.

Tips for Accurate Dirt Calculation

  1. Measure Twice: Always double-check length, width, and depth. Accuracy in measurements ensures accurate results.
  2. Include Soil Type Adjustment: Soils like clay, loam, or sandy soil compact differently. Adjust for settling to avoid shortages.
  3. Plan for Extra Dirt: For uneven terrain, add 5–10% more to your estimate.
  4. Know Your Units: Depth must be in inches to match common delivery standards.
  5. Use for Multiple Projects: Calculate yardage for multiple sections separately to avoid miscalculations.
  6. Keep Track of Volume: Use the cubic yard number for ordering, as suppliers typically charge per cubic yard.

Common Uses for a Dirt Yardage Calculator

  • Landscaping: Lawn installation, garden beds, flower beds
  • Construction: Driveways, retaining walls, backfilling
  • Gardening: Vegetable patches, raised garden beds
  • Outdoor Projects: Playgrounds, sandboxes, berms
  • Soil Replacement: Removing poor soil and replacing with high-quality fill

This calculator is suitable for homeowners, landscapers, contractors, and DIY enthusiasts.
