Shortfin mako is about 1.78× longer by these reference values.
Shortfin mako uses a 4.45 m upper reference, compared with 2.5 m for Hybodus. 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
Hybodus is represented by about 2.5 m / 8.2 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. The genus spans a long interval and multiple species; this is a comparison reference. Record length and mass do not necessarily describe the same individual.
Bite evidence
Hybodus: Tooth form suggests diet, not an exact force. Shortfin mako: No directly comparable maximum bite-force estimate is used.
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
It was a shark-line relative, not a member of a living shark order. Speed is its signature; the biggest animals are unusual and hard to verify.
