How it works
Length times width times depth gives the volume of one layer. Depth matters most: a few extra inches over a large lawn adds a lot of soil.
The settling allowance covers the drop after soil is spread and tamped, and the uneven ground that comes with a dig or a fill.
Worked example
A lawn 30 ft by 20 ft with soil 4 in deep needs 7.78 yd³ of topsoil, with the settling allowance included.
Questions
How deep should topsoil be for a lawn?
Many lawns do well with four to six inches over the existing ground. Vegetable beds often need more, and a soil test can show what to add.
Why order more than the math shows?
Soil settles after it is spread, so the finished layer comes out thinner than the pile. A small allowance avoids a short final load.
What if I need less than one load?
Ask about smaller deliveries or bagged topsoil for the last few yards.
