Planning a garden or repotting plants? Use our free Potting Soil Calculator to accurately determine the exact amount of soil needed for any rectangular or circular container, raised bed, or garden plot. Avoid overbuying or running short, ensuring your plants thrive. Calculate soil volume in cubic feet, cubic yards, liters, or gallons for efficient gardening.
Formula:
For Rectangular/Square Planters:
Volume = Length × Width × Depth
For Circular Planters/Pots:
Volume = π × (Diameter / 2)² × Depth
Where:
- Length: The longest side of your rectangular planter.
- Width: The shorter side of your rectangular planter.
- Diameter: The distance across the widest part of your circular pot.
- Depth: The desired soil height for your planter or pot.
