Megalodon is about 2.6× longer by these reference values.
Megalodon uses a 15.3 m upper reference, compared with 6 m for Great white shark. Megalodon'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 SETS THEM APART
More than a size contest.
Length and weight
Megalodon is represented by evidence-based upper estimate 14.1–15.3 m / 46–50 ft; Great white shark by about 6 m / 20 ft. No complete skeleton exists; 15.3 m is an evidence-based maximum from museum specimens, not a tape measurement. Maximum length and mass are exceptional upper-end figures.
Habitat and diet
Megalodon: Warm and temperate seas worldwide; large marine mammals, turtles and fishes. Great white shark: Temperate seas worldwide; fish, rays and marine mammals.
Bite evidence
Megalodon: Finite-element scaling produced a range, not a directly measured bite. Great white shark: A 3-D finite-element model predicted the bite of a very large individual; it was not measured on a living shark.
Fossils change the certainty
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
