What it does – The Topsoil Calculator takes the length and width of your lawn in feet and the depth of soil you want in inches, then instantly converts those dimensions into cubic yards, cubic feet, and an approximate tonnage. Why it matters – Knowing the exact volume prevents over‑ordering (which wastes money) or under‑ordering (which delays planting). The tool uses the standard conversion of 27 cubic feet per cubic yard and assumes 1.3 US tons per cubic yard, so the ton estimate is a reliable guide for delivery quotes. How to read the results – Cubic yards is the most common ordering unit for suppliers; cubic feet helps you visualize the pile size; tons gives a weight reference for truck capacity. All results appear immediately after you press Calculate, letting you plan your purchase with confidence.

Pro tips

  • Add 5‑10% extra volume to cover settling.
  • Round up to the nearest 0.1 cubic yard for supplier pricing.
  • Order by weight if the supplier quotes tons, using 1.3 tons per cubic yard.
  • Measure depth at several spots and use the average to avoid under‑estimation.

Case study

Emily needed a new lawn for her backyard. She entered 30 ft by 20 ft and a 2‑inch depth, and the calculator showed 0.44 cubic yards (≈0.57 tons). She ordered 0.5 cubic yards, saved $45 on excess soil, and had the topsoil delivered in one truck, finishing planting on schedule.

Frequently asked questions

How do I convert the calculator result to the amount I should order?
Use the cubic yards value; most suppliers price per cubic yard, and you can add a small waste factor.
Why does the ton estimate differ from the supplier’s quote?
The calculator assumes 1.3 US tons per cubic yard, which is a standard average; actual weight can vary with moisture.
Can I enter a depth in centimeters?
Convert centimeters to inches first (1 in = 2.54 cm) then enter the inch value.
Do I need to account for slope?
For a sloped lawn, calculate the average depth across the area or split the lawn into sections and sum the results.
Is the calculator accurate for large projects?
Yes, it uses the same conversions regardless of size; just ensure measurements are precise.
