Whale shark is about 1.91× longer by these reference values.
Whale shark uses a 12.2 m upper reference, compared with 6.4 m for Greenland shark. Whale shark's weight reference is about 21× 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; Whale shark by well documented near 12.2 m / 40 ft. Age and upper mass involve uncertainty; length is better documented. Exceptional historical lengths exist, but 12.2 m is a conservative comparison value.
Bite evidence
Greenland shark: TuffShark found no defensible species-level bite-force estimate to display. 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
The age estimate is extraordinary; a dependable bite-force figure is not available. The largest living fish is a filter feeder, so a predatory bite ranking would mislead.
