Kodiak bear
An average adult male measures in length, and stands tall at the shoulder. The largest recorded wild male weighed , and had a hind foot measurement of . A large male Kodiak bear stands up to tall at the shoulder, when it is standing on all four legs. When standing fully upright on its hind legs, a large male could reach a height of . The largest verified size for a captive Kodiak bear was for a specimen that lived at the Dakota Zoo in Bismarck, North Dakota. Nicknamed "Clyde," he weighed when he died in June 1987 at the age of 22. According to zoo director Terry Lincoln, Clyde probably weighed close to a year earlier. He still had a fat layer of when he died.
Brown bear
The normal range of physical dimensions for a brown bear is a head-and-body length of and a shoulder height of . The tail is relatively short, as in all bears, ranging from in length. The smallest brown bears, females during spring among barren-ground populations, can weigh so little as to roughly match the body mass of males of the smallest living bear species, the sun bear ("Helarctos malayanus"), while the largest coastal populations attain sizes broadly similar to those of the largest living bear species, the polar bear. Interior brown bears are generally smaller than is often perceived, being around the same weight as an average lion, at an estimate average of in males and in females, whereas adults of the coastal populations weigh about twice as much. The average weight of adult male bears from 19 populations, from around the world and various subspecies (including both large- and small-bodied subspecies), was found to while adult females from 24 populations were found to average .
