Bull shark is about 2.2× longer by these reference values.
Bull shark uses a 4 m upper reference, compared with 1.8 m for Blacktip reef shark. Bull shark'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
Blacktip reef shark is represented by recorded to 1.8 m / 5.9 ft; Bull shark by reported to 4 m / 13 ft. Most individuals are under 1.6 m. The 4 m figure is a reported maximum; typical mature animals are smaller.
Bite evidence
Blacktip reef shark: No standardized maximum is used. 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.
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 freshwater range is exceptional among large coastal sharks.
