How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Read cubic yards, tons, and cubic feet results.

What it does – The calculator converts the dimensions you input (length ft, width ft, depth in) into three useful quantities: cubic yards of topsoil, an approximate weight in US tons, and cubic feet.

Why it matters – Ordering the right amount avoids costly over‑orders or a half‑finished garden. One cubic yard equals 27 cubic feet, and we estimate weight at 1.3 tons per cubic yard.

How to read – The cubic‑yard figure tells you how many full‑size loads to request from a supplier; the ton value helps you compare freight quotes; the cubic‑feet number is handy for small‑scale projects.

Example – A 20 ft × 30 ft area 6 in deep yields 300 ft³, which is 11.1 yd³ and about 14.4 tons.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest whole cubic yard for delivery.
  • Order a full‑yard extra if you plan to spread later.
  • Double‑check depth conversion from inches to feet.

Real-life examples

  • Planning a new flower bed for a backyard remodel.
  • Estimating topsoil for leveling a driveway after pothole repairs.
  • Preparing a raised garden plot for vegetable planting.

Case study

Jane needed soil for a 15 ft × 20 ft patio garden 4 in deep. Using the calculator she saw she required 8.9 yd³ (≈11.6 tons) and ordered 9 yd³, avoiding a costly over‑order and finishing the project on schedule.

Frequently asked questions

How do I convert my garden dimensions to topsoil volume?
Enter length and width in feet, depth in inches; the tool returns cubic yards, tons, and cubic feet automatically.
Why is the ton estimate different from the exact weight?
We use a standard estimate of 1.3 US tons per cubic yard, which is common for average moist topsoil.
Should I order more topsoil than the calculator shows?
Add a 5‑10% buffer for settling and spillage, then round up to the nearest whole yard.
Can I use the calculator for multiple garden beds?
Yes, sum the length × width for each bed, keep the same depth, and enter the total dimensions.
What if my depth is in centimeters?
Convert centimeters to inches (1 cm ≈ 0.39 in) before entering the depth.
