Whale shark is about 10× longer by these reference values.
Whale shark uses a 12.2 m upper reference, compared with 1.22 m for Horn shark. Whale shark's weight reference is about 2100× 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
Horn shark is represented by reported to 1.22 m / 4 ft; Whale shark by well documented near 12.2 m / 40 ft. Weight is a rounded adult reference. Exceptional historical lengths exist, but 12.2 m is a conservative comparison value.
Bite evidence
Horn shark: Experiments also measured bites; the displayed range is the study's theoretical maximum from front to rear teeth. Whale shark: Whale sharks filter feed; a comparable maximum bite-force study is not available.
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 rear teeth crush hard prey, and its bite mechanics have been tested directly and modeled. The largest living fish is a filter feeder, so a predatory bite ranking would mislead.
