What is the typical weight of a newborn polar bear?

A newborn polar bear typically weighs about 0.7 kg, or roughly 700 grams. That is only around 1.5 pounds, astonishingly small for the largest living bear species.

Polar bear cubs are born during winter, usually inside a snow den built by their mother. At birth they are blind, helpless, lightly furred, and lack the insulating fat needed to withstand Arctic conditions outdoors. The den protects them from the cold while the mother nurses them with exceptionally rich milk.

The cubs grow rapidly during their first months. When the family emerges from the den in spring, a cub may weigh around 10 to 12 kg. Twins are common, although single cubs and triplets also occur. The stored answer is a reasonable rounded figure: scientific and wildlife sources often report newborn weights from about 0.6 to 0.7 kg, with variation among individuals. A common mistake is confusing birth weight with den-emergence weight, which is many times greater.
