About this calculator

A cylindrical pot's soil capacity follows the standard cylinder volume formula, V = π × r² × h, using the pot's radius (half its diameter) and height. This calculator runs that formula and converts the result into litres and gallons, the units potting soil is typically sold in.

Gardeners use it before a potting session to buy the right number of bags rather than guessing and either running short mid-project or hauling home unused soil. It's also handy for comparing how much medium different pot sizes will actually hold.
