What is the size of a killer whale? Quick Answer. According to Defenders of Wildlife, male killer whales grow up to 23 feet in length and weigh from 7 to 10 tons. Female whales grow up to 23 feet when fully grown and weigh anywhere from 4 to 6 tons.
Female killer whales reach sexual maturity when they grow to about 15-18 feet (4.6 m-5.4 m) long, depending on geographic region. The gestation period for killer whales varies from 15-18 months. Birth may take place in any month--there is no distinct calving season. Calves are nursed for at least 1 year, and may be weaned between 1-2 years old. The birth rate for killer whales is not well understood, but, in some populations, is estimated as every 5 years for an average period of 25 years. Killer whales are highly social animals that occur primarily in relatively stable social groups that often range in size from 2 to 15 animals.
