Estimate topsoil needed in cubic feet, cubic yards, cubic meters, and bags for lawns, gardens, raised beds, leveling projects, and landscape areas.
Volume formula:
Length × width × depth = total topsoil volume
Conversion formula:
Cubic feet ÷ 27 = cubic yards
This calculator estimates topsoil volume, cubic yards, cubic meters, and approximate bag count.
Knowing how much topsoil you need helps when planning lawns, beds, and landscape projects so you can buy enough material without overspending.
Correct soil depth helps support seed, sod, garden plants, drainage, and grading results.
Your result shows the estimated topsoil volume based on the area dimensions and depth entered. It also includes cubic yards and an approximate number of bags based on the selected bag size.
Actual needs can vary depending on settling, compaction, and how evenly the soil is spread. For larger jobs, ordering bulk topsoil by the cubic yard is usually more practical than bags.
Multiply the area length by width and then by the soil depth to estimate total topsoil volume.
One cubic yard equals 27 cubic feet.
Many lawn and garden projects use 2 to 6 inches depending on the purpose and planting needs.
Small projects are often easier with bags, while larger projects are usually more economical with bulk topsoil.
