White shark is about 3.3× longer by these reference values.
White shark uses a 6 m upper reference, compared with 1.8 m for Blacktip reef shark. White shark's weight reference is about 95× 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; White shark by about 6 m / 20 ft. Most individuals are under 1.6 m. Maximum length and mass are exceptional upper-end figures.
Bite evidence
Blacktip reef shark: No standardized maximum is used. White shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark.
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 headline bite number is a computer model, not a live-animal measurement.
