The only other bear of a similar size to the polar bear is the Kodiak bear, which is a subspecies of brown bear. Adult male polar bears weigh 350â700 kg (772â1,543 lb) and measure 2.4â3 metres (7 ft 10 inâ9 ft 10 in) in total length.
1 Male polar bears (boars) grow two to three times the size of females (sows). Boars weigh about 350 to more than 650 kg (772-1,433 lb.) and are about 2.5 to 3 m (8.2-9.8 ft.) long.  Sows weigh about 150 to 250 kg (331-551 lb.) and are about 1.8 to 2.5 m (6.0-8.2 ft.) long.
