Soil Volume Calculator

How to Use This Calculator

This soil calculator makes it easy to estimate volume for any project. Enter the length and width of the area in feet, and the desired soil depth in inches. This dirt calculator shows the total volume needed in cubic yards (for bulk delivery), cubic feet, and estimated weight in tons for planning delivery logistics.

Why This Matters

Raised beds, garden fill, and landscaping projects require precise soil volumes. A reliable soil estimator prevents costly mistakes — ordering too little means a second delivery charge; ordering too much wastes money and leaves excess material with no place to put it. Accurate calculation saves both time and money.

Methodology

This soil measurement calculator uses: Cubic feet = Length (ft) × Width (ft) × Depth (in) / 12. Cubic yards = Cubic feet / 27. Estimated tons = Cubic yards × 1.1 (average dry topsoil density). One cubic yard of topsoil weighs approximately 2,000-2,400 lbs depending on moisture.

Common Mistakes to Avoid

• Forgetting to convert depth from inches to feet before calculating volume.
• Not adding 10-15% extra for settling — fresh fill settles 10-15% over the first year.
• Estimating area by eye instead of measuring, which leads to ordering errors.
• Not checking that the delivery truck can access your site — a loaded dump truck weighs 25-30 tons.
