Estimate liters, cubic feet and bags of potting mix for cylindrical planters.
Use this as a planning estimate. Verify product labels, local conditions and supplier packaging before buying or applying materials.
Each container is modeled as a cylinder: π × radius² × fill height. Total volume multiplies by the number of pots and converts cubic inches to liters.
SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.
This calculator uses a cylinder, so strongly tapered containers will need less mix than the estimate. Use the average of top and bottom diameters for a closer approximation.
Subtract any meaningful insert volume, though a drainage hole and suitable mix are generally more useful than a deep rock layer.
