Volume needed = Length × Width × Depth, converted to cubic feet, then divided by your chosen bag size to get a bag count. This calculator is focused on bagged garden or potting soil for beds and containers, common bag sizes are 0.75, 1.5 and 2 cubic feet.
This calculator is built around bag counts for smaller projects like raised beds, garden borders or containers. For larger areas like a new lawn or major grading project, bulk topsoil delivered by the cubic yard is typically far more cost-effective than buying many bags, our Topsoil Calculator handles that bulk delivery case, working in cubic yards and delivered tons.
This calculator's volume math works the same regardless of soil type, garden soil is typically used for in-ground beds, while potting soil (usually lighter and better draining) is intended for containers. Check the bag size for your specific product.
For larger areas, generally more than a few cubic yards, bulk delivery is usually significantly cheaper per unit of coverage than buying many individual bags. Our Topsoil Calculator is built for that bulk delivery scenario.
Not necessarily, many gardeners fill the bottom portion of a deep raised bed with cheaper fill material and reserve quality garden soil for the top layer where roots are most active, adjust your depth input accordingly if you're doing this.
