In container shipping, size matters! Not just for scale, but for which ports a ship can serve, which trade lanes it can ply, how much cargo it can carry, and what cost efficiencies it can achieve. As vessels grew over the decades, the shipping industry adopted size categories (measured in TEU and physical dimensions) to classify container ships. Understanding categories like feeder, Panamax, Neo-Panamax, and ULCV helps shippers and ports align expectations, infrastructure, and strategy.
