Greenland shark is about 1.44× longer by these reference values.
Greenland shark uses a 6.4 m upper reference, compared with 4.45 m for Shortfin mako. Greenland shark's weight reference is about 1.79× 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
Greenland shark is represented by confirmed to about 6.4 m / 21 ft; Shortfin mako by reported to about 4.45 m / 14.6 ft. Age and upper mass involve uncertainty; length is better documented. Record length and mass do not necessarily describe the same individual.
Bite evidence
Greenland shark: TuffShark found no defensible species-level bite-force estimate to display. 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
The age estimate is extraordinary; a dependable bite-force figure is not available. Speed is its signature; the biggest animals are unusual and hard to verify.
