Bull shark is about 1.05× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. Bull shark's weight reference is about 1.54× 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
Blue shark is represented by about 3.8 m / 12.5 ft; Bull shark by reported to 4 m / 13 ft. Upper records are uncommon; most adults are lighter. The 4 m figure is a reported maximum; typical mature animals are smaller.
Bite evidence
Blue shark: No comparable maximum is used. Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite.
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 long fins and slender build matter more than raw bulk. Its freshwater range is exceptional among large coastal sharks.
