Common thresher is about 1.90× longer by these reference values.
Common thresher uses a 7.6 m upper reference, compared with 4 m for Bull shark. Common thresher's weight reference is about 1.07× 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
Bull shark is represented by reported to 4 m / 13 ft; Common thresher by reported to 7.6 m / 24.9 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Length comparisons can exaggerate body bulk because the tail is exceptionally long.
Bite evidence
Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. Common thresher: Its hunting performance cannot be reduced to jaw force.
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 freshwater range is exceptional among large coastal sharks. Much of its length is tail, which it uses to stun prey.
