How to use it

  1. Enter length, width (ft) and depth (in).
  2. Click “Calculate”.
  3. Read cubic yards, tons, and cubic feet results.

This tool converts the dimensions of your planting area into three practical units: cubic yards, tons, and cubic feet. Knowing the cubic yards tells you how many bulk deliveries to order; the ton estimate helps you budget for material weight; cubic feet is useful for smaller bags. The calculator automatically changes inches to feet, multiplies length × width × depth, and divides by 27 to get yards. For example, a 10 ft × 20 ft space at 4 in depth yields 2.47 cubic yards, ≈3.2 tons, and 66.7 cubic feet. Use these numbers to order the right amount without over‑buying or running short.

Pro tips

  • Add 5‑10 % extra for settling and compaction.
  • Round up to the nearest half‑yard when ordering bulk.
  • Order slightly more than calculated to avoid multiple deliveries.
  • Always double‑check depth conversion from inches to feet.

Real-life examples

  • A homeowner landscaping a new flower bed.
  • A contractor preparing a yard for re‑grading.
  • A gardener filling raised beds for vegetable planting.

Case study

Jane needed a 12 ft × 15 ft lawn patch 3 in deep. Using the calculator she saw she required 1.85 cubic yards (≈2.4 tons). She ordered 2 cubic yards, saved a delivery, and completed the job on budget.

Frequently asked questions

How do I convert depth inches to feet?
Divide the inches by 12; the calculator does it automatically.
Why is the ton estimate different from weight on the bag?
We use a standard 1.3 tons per cubic yard for bulk topsoil; bag weights can vary.
Should I order more than the exact amount?
Yes, add 5‑10 % for compaction and spillage.
Can I use the calculator for sand or mulch?
It works for any material measured in cubic yards; adjust the ton factor if needed.
Is the calculator accurate for irregularly shaped areas?
It’s best for rectangular plots; break irregular areas into rectangles and sum the results.
