Common thresher is about 4.2× longer by these reference values.
Common thresher uses a 7.6 m upper reference, compared with 1.8 m for Blacktip reef shark. Common thresher's weight reference is about 14× 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; Common thresher by reported to 7.6 m / 24.9 ft. Most individuals are under 1.6 m. Length comparisons can exaggerate body bulk because the tail is exceptionally long.
Bite evidence
Blacktip reef shark: No standardized maximum is used. 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
It is far smaller than the offshore giants people often picture. Much of its length is tail, which it uses to stun prey.
