Great hammerhead is about 1.72× longer by these reference values.
Great hammerhead uses a 6.1 m upper reference, compared with 3.54 m for Zebra shark. Great hammerhead's weight reference is about 13× heavier.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.
THE NUMBERS
Side by side.
WHAT THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Great hammerhead is represented by reported to 6.1 m / 20 ft; Zebra shark by reported to 3.54 m / 11.6 ft. The comparison uses the largest reported length and a record mass. Its very long tail adds substantially to total length.
Bite evidence
Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here. Zebra shark: No standardized maximum is used.
Living versus extinct
Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
Ecology changes the matchup
Its wide head is a sensory platform, not just an unusual silhouette. Juveniles have stripes; adults are spotted despite the common name.
