Common thresher is about 1.23× longer by these reference values.
Common thresher uses a 7.6 m upper reference, compared with 6.17 m for Goblin shark. Common thresher's weight reference is about 1.62× 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
Common thresher is represented by reported to 7.6 m / 24.9 ft; Goblin shark by photo-based estimates to 5.4–6.17 m / 18–20 ft. Length comparisons can exaggerate body bulk because the tail is exceptionally long. The longest figures come from regression estimates based on photographs.
Bite evidence
Common thresher: Its hunting performance cannot be reduced to jaw force. 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
Much of its length is tail, which it uses to stun prey. Its jaws shoot forward rapidly; maximum body size remains uncertain.
