How to use it

  1. Enter length in feet, width in feet, and depth in inches.
  2. Click Calculate.
  3. Read the cubic yards and cubic feet results.

What it does – The Cubic Yards Calculator turns your length, width and depth measurements into the volume you’ll actually order. Why it matters – Ordering too little means extra trips and higher cost; ordering too much wastes money and space. How to read it – The result in cubic feet shows the exact volume; divide by 27 (or use the cubic yards value) to see how many full yards of material you’ll need. Enter your dimensions, hit calculate, and you get both numbers instantly. Landscapers use it for soil, gardeners for mulch, contractors for concrete. The calculator handles any shape that can be approximated as a rectangular prism, which covers most backyard jobs. Because depth is entered in inches, you don’t have to convert manually – the tool does the math and presents the two standard units used by suppliers.

Pro tips

  • Add a 10% waste allowance to cover compaction and spillage.
  • Round up to the nearest half‑yard to match supplier minimums.
  • Double‑check depth measurement; use the center depth for uneven ground.
  • Compare supplier pricing per cubic yard before ordering.

Real-life examples

  • A homeowner estimating how much topsoil to fill a 12‑ft garden bed 6 in deep.
  • A contractor calculating concrete volume for a 20‑ft patio 4 in thick.
  • A landscaper planning mulch for a 30‑ft by 15‑ft area with a 3‑in depth.

Case study

Jane needed soil for a new raised garden. She entered 10 ft × 8 ft × 6 in and the calculator showed 1.78 cubic yards. She ordered two yards, avoiding a costly second delivery and finishing her project on schedule.
