How to Calculate Soil Volume

Multiply the length by the width to get the area in square feet. Convert the depth from inches to feet by dividing by 12. Multiply the area by the depth in feet to get cubic feet. Divide by 27 to convert to cubic yards. One cubic yard covers approximately 324 square feet at 1 inch deep.

Choosing the Right Soil

Topsoil is best for general landscaping and filling low spots. Garden soil is enriched with compost for planting beds. Potting mix is lightweight and used for containers. For raised beds, a mix of 60% topsoil, 30% compost, and 10% perlite or vermiculite provides good drainage and nutrients.
