Megamouth shark is about 1.15× longer by these reference values.
Megamouth shark uses a 7.1 m upper reference, compared with 6.17 m for Goblin shark. Megamouth shark's weight reference is about 5.8× 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
Goblin shark is represented by photo-based estimates to 5.4–6.17 m / 18–20 ft; Megamouth shark by reported to about 7.1 m / 23 ft. The longest figures come from regression estimates based on photographs. Sparse specimens make a true maximum difficult to establish.
Bite evidence
Goblin shark: Jaw speed and protrusion are not the same measurement as bite force. Megamouth shark: This filter feeder lacks a comparable maximum-bite study.
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. Known from relatively few encounters, it still carries major uncertainty.
