Goblin shark is about 2.1× longer by these reference values.
Goblin shark uses a 6.17 m upper reference, compared with 3 m for Lemon shark. Lemon shark's weight reference is about 1.19× 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
Goblin shark is represented by photo-based estimates to 5.4–6.17 m / 18–20 ft; Lemon shark by commonly to 3 m / 10 ft. The longest figures come from regression estimates based on photographs. The values are upper-end figures, not a typical adult profile.
Bite evidence
Goblin shark: Jaw speed and protrusion are not the same measurement as bite force. Lemon shark: No standardized maximum is available for a fair cross-species comparison.
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 jaws shoot forward rapidly; maximum body size remains uncertain. Decades of field research make this one of the best-studied coastal sharks.
