Great hammerhead is about 1.37× longer by these reference values.
Great hammerhead uses a 6.1 m upper reference, compared with 4.45 m for Shortfin mako. Shortfin mako's weight reference is about 1.27× 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; Shortfin mako by reported to about 4.45 m / 14.6 ft. The comparison uses the largest reported length and a record mass. Record length and mass do not necessarily describe the same individual.
Bite evidence
Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here. Shortfin mako: No directly comparable maximum bite-force estimate 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. Speed is its signature; the biggest animals are unusual and hard to verify.
