Goblin shark is about 1.01× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. Great hammerhead's weight reference is about 2.1× 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; Great hammerhead by reported to 6.1 m / 20 ft. The longest figures come from regression estimates based on photographs. The comparison uses the largest reported length and a record mass.
Bite evidence
Goblin shark: Jaw speed and protrusion are not the same measurement as bite force. Great hammerhead: Comparative biomechanics exist, but a simple verified maximum is not established here.
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. Its wide head is a sensory platform, not just an unusual silhouette.
