Why a larger carrier is not automatically better

How much did the larger Lexington hull make a better carrier than the Amagi class?

It provided useful physical margins, but the decisive difference depended on how the carrier and its air group were organized, trained, and employed.

Size gives a conversion more room for flight deck and hangar space and makes top-weight distribution easier. Those physical advantages do not dictate combat effectiveness on their own. Like selecting and carefully using the right tool, a carrier's results depend on its air group, deployment, crew training, support, and the quality of its operating procedures. The comparison is therefore about usable margins and institutional practice, not a simple displacement ranking between Lexington and Amagi.
