Goblin shark is about 3.4× longer by these reference values.
Goblin shark uses a 6.17 m upper reference, compared with 1.8 m for Blacktip reef shark. Goblin shark's weight reference is about 8.8× 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; Goblin shark by photo-based estimates to 5.4–6.17 m / 18–20 ft. Most individuals are under 1.6 m. The longest figures come from regression estimates based on photographs.
Bite evidence
Blacktip reef shark: No standardized maximum is used. Goblin shark: Jaw speed and protrusion are not the same measurement as bite 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. Its jaws shoot forward rapidly; maximum body size remains uncertain.
