How to use it

  1. Enter length (ft) and width (ft) of the area.
  2. Enter depth (in) of the material.
  3. Click “Calculate” to see cubic feet, cubic yards, and tons.
  4. Use the results to order the right amount of material.

The Dirt Coverage Calculator instantly converts the dimensions of a soil or gravel project into the three units contractors and DIYers need: cubic feet, cubic yards, and approximate tons. Enter the length and width in feet and the depth in inches, and the tool does the math for you. Knowing cubic yards tells you how many bulk bags to order, while the ton estimate helps you compare material costs and truck load limits. The results appear in a clear table: cubic feet for quick area checks, cubic yards for supplier quotes, and tons for weight‑related planning. No hidden fees, no sign‑up—just fast, free numbers you can trust. Use the calculator before ordering to avoid over‑buying, to schedule deliveries, and to keep your project on budget.

Pro tips

  • Add 10% extra for compaction and spillage.
  • Round up to the nearest half‑yard for bulk orders.
  • Compare ton estimates with truck load limits before scheduling delivery.
  • Double‑check depth measurement; a small error greatly changes volume.

Real-life examples

  • A homeowner planning to spread new topsoil for a garden bed.
  • A contractor estimating gravel for a driveway base.
  • A landscaper ordering sand to level a patio area.

Case study

Jane needed 500 sq ft of garden soil 4 in deep. Using the calculator she saw the job required 0.61 cubic yards (≈0.8 tons). She ordered 1 cubic yard, avoiding a costly over‑order and completed the bed on schedule.

Frequently asked questions

How do I convert depth from inches to feet?
Divide the inch value by 12; the calculator does this automatically.
Why does the ton estimate differ from supplier quotes?
The tool uses a standard 1.3 tons per cubic yard; actual material density can vary slightly.
Can I use the calculator for sand or mulch?
Yes, the volume conversion is the same; adjust the weight if you need a more precise ton estimate.
What if my area isn’t a perfect rectangle?
Break the space into smaller rectangles, calculate each, then add the results.
Do I need to account for compaction?
Add a 5‑10% waste allowance to the final cubic‑yard figure for compaction and spillage.
