Topsoil Calculator
Estimate topsoil volume and approximate mass for a rectangular area.
How to Use the Topsoil Calculator
Enter the area dimensions and desired soil depth to estimate topsoil volume and approximate weight.
Practical Example
A 10 m by 4 m bed covered with 10 cm of topsoil needs about 4 m³ before settling.
Factors That Affect the Result
Soil density, moisture, compaction, settling, irregular bed shapes and delivery units can affect the final quantity.
Frequently Asked Questions
Should I allow for settling?
Yes. Fresh soil can settle after watering and compaction.
Can I calculate multiple beds?
Yes. Calculate each area and add the volumes.
Does soil weight vary?
Yes. Moisture content and soil composition affect weight.

Topsoil Estimation Tips
Measure the area to be covered and enter the desired soil depth to estimate the required topsoil volume. Garden beds, lawns and uneven ground often need slightly more material than a perfect rectangular calculation suggests. Soil can also settle after spreading, so adding a modest allowance helps avoid running short. When ordering by cubic yard or cubic meter, round up to the supplier’s available delivery increment and confirm whether the quoted volume refers to loose or compacted material.
