Basking shark is about 6.7× longer by these reference values.
Basking shark uses a 12 m upper reference, compared with 1.8 m for Blacktip reef shark. Basking shark's weight reference is about 250× 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
Basking shark is represented by reported to 12 m / 40 ft; Blacktip reef shark by recorded to 1.8 m / 5.9 ft. The upper length is exceptional; the mass is a rounded comparison estimate. Most individuals are under 1.6 m.
Bite evidence
Basking shark: A comparable maximum-bite study is not available for this filter feeder. Blacktip reef shark: No standardized maximum 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 enormous mouth strains plankton; it is not built for a giant predatory bite. It is far smaller than the offshore giants people often picture.
