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 THE DATA CAN SAY
Size is not the whole animal.
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.
Bite evidence
Frilled shark: No standardized maximum is available. Megalodon: Finite-element scaling produced a range, not a directly measured bite.
Living versus extinct
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
Ecology changes the matchup
Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils. Nearly every whole-body number is reconstructed from teeth and comparisons with living sharks.
