White shark is about 1.25× longer by these reference values.
White shark uses a 6 m upper reference, compared with 4.8 m for Bluntnose sixgill. White shark's weight reference is about 3.8× 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
Bluntnose sixgill is represented by reported to 4.8 m / 15.8 ft; White shark by about 6 m / 20 ft. Deepwater sampling is difficult, so upper records are sparse. Maximum length and mass are exceptional upper-end figures.
Bite evidence
Bluntnose sixgill: No standardized maximum is available. White shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark.
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
Its six gill slits mark an ancient branch of shark diversity. Its headline bite number is a computer model, not a live-animal measurement.
