Most adult female grizzlies weigh 130–180 kg (290–400 lb), while adult males weigh on average 180–360 kg (400–790 lb). Average total length in this subspecies is 198 cm (6. 50 ft), with an average shoulder height of 102 cm (3. 35 ft) and hindfoot length of 28 cm (11 in). Newborn bears may weigh less than 500 grams (1. 1 lb). In the Yukon River area, mature female grizzlies can weigh as little as 100 kg (220 lb). For a female, these average weights would be 136 kg (300 lb) inland and 227 kg (500 lb) coastal, respectively. One study found that the average weight for an inland male grizzly was around 272 kilograms (600 pounds), and the average weight for a coastal male was around 408 kg (899 lb).
