What it does – The Yard Dirt Calculator turns the dimensions of a fill area into three useful measures: cubic yards, cubic feet, and an approximate tonnage. Knowing the exact volume prevents ordering too little material, which can delay a project, or too much, which wastes money. Why it matters – Contractors and DIY homeowners use cubic yards to order bulk dirt, while the ton estimate helps compare delivery costs that are often priced per ton. How to read the results – Cubic yards is the standard bulk‑order unit; cubic feet lets you verify the math or plan smaller jobs; the ton figure is a quick cost proxy based on 1.3 US tons per cubic yard. Enter length, width, and depth, hit calculate, and you get an instant, free snapshot of what you need.

Pro tips

  • Add 10% extra for compaction and settling.
  • Round up the cubic yards to the nearest 0.1 for ordering.
  • Compare supplier quotes using the ton estimate.
  • Double‑check depth conversion from inches to feet.

Real-life examples

  • A homeowner preparing a garden bed needs to know how much topsoil to order.
  • A contractor filling a foundation trench wants to avoid costly material shortfalls.
  • A landscaper estimating material for a new lawn level‑off wants quick tonnage for budgeting.

Case study

Maria needed to fill a 12‑ft × 8‑ft patio trench 4 in deep. The calculator showed 0.89 cubic yards (≈1.2 tons). She ordered 1 ton of dirt, saving a delivery fee and avoiding a second trip. The project stayed on schedule and under budget.

Frequently asked questions

How do I convert depth in inches to cubic yards?
Enter the depth in inches; the calculator handles the conversion to feet before computing volume.
Why does the ton estimate differ from my supplier’s quote?
The calculator uses 1.3 US tons per cubic yard, a standard approximation; actual weight can vary with moisture.
Should I order more dirt than the calculator shows?
Add a 10% waste allowance to cover compaction, settling, and spillage.
Can I use this for sand or gravel?
Yes, the volume calculations are the same; adjust the weight per yard if you need a different ton estimate.
Is the result in US tons or metric tons?
The ton figure is in US tons (1.3 tons per cubic yard).
