How Long Is A Blue Whale

The International Whaling Commission (IWC) reported 88 individuals of more than 30 meters (98 feet) in length, which one was 33 meters (108 feet) long. However, problems with taking measurements suggest that any individual longer than 30.5 meters (100 feet) is uncertain. The Discovery Committee reported the length of blue whales as up to 31 meters (102 feet). The scientifically measured longest individual was 30 meters (98 feet) long.

Models based on the hydrodynamic study suggest that the length of a blue whale could not exceed 33 meters (108 feet) because of metabolic and energy limitations. National Geographic shows the length of a blue whale from 25 to 32 meters (82 to 105 feet). The average length of adult female blue whales in the Eastern North Pacific habitat was recorded as 22.0 meters (72.1 feet), in the Central and Western North Pacific was 24 meters (79 feet), in the North Atlantic was 21 to 24 meters (68 to 78 feet), and in the Antarctic ocean was 25.4 to 26.3 meter (83.4 to 86.3 feet).
