Common thresher is about 2.0× longer by these reference values.
Common thresher uses a 7.6 m upper reference, compared with 3.8 m for Blue shark. Common thresher's weight reference is about 1.65× 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; Common thresher by reported to 7.6 m / 24.9 ft. Upper records are uncommon; most adults are lighter. Length comparisons can exaggerate body bulk because the tail is exceptionally long.
Bite evidence
Blue shark: No comparable maximum is used. Common thresher: Its hunting performance cannot be reduced to jaw force.
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. Much of its length is tail, which it uses to stun prey.
