Standard Flower Pot Sizes Explained

Standard pots have equal top diameter and height (e.g., 8" wide × 8" tall). Azalea pots are ¾ as tall as wide; bulb pans are half as tall. Sizes step by 2 inches (2", 4", 6"…14", then 17", 21"). Larger pots switch to gallon designations. Hanging baskets (6", 8", 10") have rounded bottoms and attached hangers. Many retailers deviate from standards, so measure before buying.
