What makes a naval battle the largest?

Which naval battle should be considered the largest in history?

The Philippine Sea is proposed for ships and area, and Jutland for a concentrated fleet battle; the choice depends on the measure.

The Philippine Sea is the choice offered when considering the number of ships and area involved, with the qualification that the fighting divides into many smaller actions. Jutland is suggested for a more concentrated battle. Chinese accounts introduce another difficulty because some very large claimed fleets are hard to reconcile with the geography. Much Chinese battle reporting is accepted while particular enormous totals are treated as possible expansion during retelling. Cape Ecnomus is also acknowledged as a remarkable candidate.
