A newborn elephant weighs between 200 and 320 pounds (90–145 kg) at birth — making elephant calves among the heaviest land-mammal newborns on Earth. That weight is not accidental. It is the direct result of a 22-month pregnancy, the longest of any land mammal, during which the calf develops to a level of physical maturity that allows it to walk, nurse, and keep pace with the herd within hours of being born.
The short answer: A newborn elephant typically weighs between 200–320 lbs (90–145 kg) — roughly the size of a large adult human multiplied by 1.5. African bush elephant calves are the largest at birth; Asian elephants are slightly smaller.
