The Life and Times of a Polar Bear

How big are polar bears? Adult males normally weigh 350- 600 kg (775-1,300 lb). Adult females are usually 150-290 kg (330-650 lb). But some can be larger. Researchers in Canada estimated one male bear at 800 kg (1,700 lb)! Polar bears are also tall. Scientists usually measure their height at the shoulder when on all fours. Those heights are typically 1-1.5 m (3.3-5 ft) for adult polar bears. An adult male may reach over 3 m (10 ft) when standing on its hind legs! | Polar Bears International
