Shortfin mako is about 1.44× longer by these reference values.
Shortfin mako uses a 4.45 m upper reference, compared with 3.08 m for Nurse shark. Shortfin mako's weight reference is about 5.2× 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
Nurse shark is represented by recorded to 3.08 m / 10.1 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. Length is a recorded maximum; mass is a rounded adult reference. Record length and mass do not necessarily describe the same individual.
Bite evidence
Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings. Shortfin mako: No directly comparable maximum bite-force estimate is used.
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
A small mouth and powerful suction suit its bottom-feeding life. Speed is its signature; the biggest animals are unusual and hard to verify.
