Anglerfish type Typical size

Monkfish / goosefish relatives Up to about 6.6 feet, or 2 meters

Why the size varies

Anglerfish are a broad group with many species, so their size depends heavily on which kind you mean. Some deep-sea species stay small, while others grow much larger, and females are often bigger than males in these fish.

A simple picture

If you imagine an anglerfish, the “classic” deep-sea version is usually closer to a small fish around a foot long than a giant monster. The bigger ones are real, but they’re the exception rather than the rule.

TL;DR

Most anglerfish are small , around 8 to 12 inches ; some grow to 3 to 4 feet ; and a few species like monkfish can get to about 6.6 feet.
