The largest gray wolf ever recorded was reportedly around 930 pounds with 4 feet in height, but the tallest and heaviest recorded grey wolves are only just over 1,000 pounds. Although it is not a record, the average weight of a purebred female Gray Wolf ranges from 155 – 165 lb (70-75 kg). Wolves can reach at least 240 lbs. for males. This is about 10% larger than German Shepherds or Black Labs.
