Grizzly bears have a massive size. Most adult female bears weigh 130–180 kg (290-400 lb), while adult males average 180–360 kg (400-790 lb). The average total length in this subspecies is 198 cm (6.50 ft), with an average shoulder height of 102 cm (3.35 ft) and a hind leg length of 28 cm (11 in). Newborn bear can weigh less than 500 grams (1.1 lb). In the Yukon River area, adult female bears can weigh at least 100 kg (220 lb). One study found that the average weight of an inland grizzly bear was about 272 kg (600 lb) and that of a coastal male was about 408 kg (900 lb). For a female, these average weights would be 136 kg (300 lb) on land and 227 kg (500 lb) on the coast, respectively. On the other hand, a giant male has occasionally been recorded to exceed normal size, with a reported weight of up to 680 kg (1,500 lb). A large, coastal male of this size can be up to 3 meters (9.8 ft) tall on both hind legs and up to 1.5 meters (4.9 ft) tall from the shoulders when standing on all fours.
