Soil Volume Calculator
Calculate the volume of soil needed for garden beds, pots, and planting areas based on dimensions.
How It Works
Enter the length, width, and desired depth of your planting area. The calculator multiplies these dimensions to give total cubic feet, then converts to cubic yards and bags.
Formula
Volume (cu ft) = Length (ft) x Width (ft) x Depth (ft)
Frequently Asked Questions
How do I calculate soil volume?
Multiply the length by the width by the depth of your garden bed. For example, a 4 ft x 8 ft bed that is 12 inches (1 ft) deep needs 32 cubic feet of soil.
How many bags of soil do I need?
A standard 1.5 cu ft bag covers 1.5 cubic feet. Divide your total cubic feet by 1.5 to get the number of bags needed.
