Megalodon is about 7.7× longer by these reference values.
Megalodon uses a 15.3 m upper reference, compared with 2 m for Frilled shark. Megalodon's weight reference is about 3200× 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
Frilled shark is represented by about 2 m / 6.6 ft; Megalodon by evidence-based upper estimate 14.1–15.3 m / 46–50 ft. Deepwater records remain limited. No complete skeleton exists; 15.3 m is an evidence-based maximum from museum specimens, not a tape measurement.
Habitat and diet
Frilled shark: Deep continental slopes; squid, fishes and small sharks. Megalodon: Warm and temperate seas worldwide; large marine mammals, turtles and fishes.
Bite evidence
Frilled shark: No standardized maximum is available. Megalodon: Finite-element scaling produced a range, not a directly measured bite.
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.
