Hybodus is about 2.0× longer by these reference values.
Hybodus uses a 2.5 m upper reference, compared with 1.22 m for Horn shark. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.

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; Hybodus by about 2.5 m / 8.2 ft. Weight is a rounded adult reference. The genus spans a long interval and multiple species; this is a comparison reference.
Bite evidence
Horn shark: Experiments also measured bites; the displayed range is the study's theoretical maximum from front to rear teeth. Hybodus: Tooth form suggests diet, not an exact force.
Living versus extinct
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
Ecology changes the matchup
Its rear teeth crush hard prey, and its bite mechanics have been tested directly and modeled. It was a shark-line relative, not a member of a living shark order.
