Great hammerhead is about 3.4× longer by these reference values.
Great hammerhead uses a 6.1 m upper reference, compared with 1.8 m for Blacktip reef shark. Great hammerhead's weight reference is about 19× 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
Blacktip reef shark is represented by recorded to 1.8 m / 5.9 ft; Great hammerhead by reported to 6.1 m / 20 ft. Most individuals are under 1.6 m. The comparison uses the largest reported length and a record mass.
Bite evidence
Blacktip reef shark: No standardized maximum is used. Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here.
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
It is far smaller than the offshore giants people often picture. Its wide head is a sensory platform, not just an unusual silhouette.
