What units does the calculator use?

Enter length and width in feet, depth in inches; results appear in cubic yards, tons (approx.) and cubic feet.

Do I need to know the soil’s exact weight?

The calculator uses the standard estimate of 1.3 US tons per cubic yard, which is accurate for most topsoil mixes.

Can I round the results for ordering?

Yes—round up the cubic yards or tons to the next whole number to ensure you have enough material.

Top Soil Calculator – How Much Top Soil Do I Need?

This How Much Top Soil Do I Need Calculator lets you turn simple garden dimensions into three practical measures: cubic yards, tons (approx.), and cubic feet.

Enter the length and width of the area in feet, then the desired depth in inches.
The tool converts the depth to feet, multiplies length × width × depth to get volume in cubic feet.
It divides that number by 27 to give cubic yards, then multiplies cubic yards by 1.3 US tons per cubic yard for an approximate weight. Worked example: A 20 ft × 15 ft garden at 4 in depth. Depth = 4 in ÷ 12 = 0.333 ft. Volume = 20 × 15 × 0.333 ≈ 100 ft³. Cubic yards = 100 ÷ 27 ≈ 3.7 yd³. Tons ≈ 3.7 × 1.3 ≈ 4.8 tons. The calculator instantly shows 3.7 yd³, 4.8 tons, 100 ft³. No guesswork, no sign‑up—just fast, reliable results for any project.
