How Long Do Blue Whales Grow? An adult blue whale can reach lengths in excess of 80 â 100 feet and weigh more than 150 tons when fully matured. Even as an infant the blue whale can measure in at around 25 ft and gain as much as 200 pounds per day during its first year of birth. Although blue whales are massive creatures they have a relatively slender body and a flat aerodynamically U-shaped head, which allows the whale to easily move through the water at high speeds.
