Gorillas are the largest primates, with size varying by species and sex. Height:
- Adult male gorillas (silverbacks) typically stand about 4 to 6 feet tall (1.2 to 1.8 meters) when upright. The tallest recorded wild silverback was 1.95 meters (6 ft 5 in) tall, and in captivity, some have reached up to 2.2 meters (7 ft 3 in)
Weight:
- Adult male gorillas weigh between 135 to 220 kilograms (300 to 485 pounds) on average, with some exceptional individuals reaching up to 267 kilograms (589 pounds) in the wild and even heavier in captivity (up to 310 kg or 683 lbs)
- Females are smaller, weighing around 68 to 113 kilograms (150 to 250 pounds) and standing about 1.25 to 1.5 meters (4 ft 1 in to 4 ft 11 in) tall
Other size features:
- Gorillas have an arm span of about 2.3 to 2.8 meters (7 ft 7 in to 9 ft 2 in), with arms longer than their legs, reflecting their evolutionary ancestry
- Their chest can be nearly 2 meters wide in large males
In summary, gorillas are massive and powerful animals, with adult males standing roughly 4 to 6 feet tall and weighing up to 220 kilograms or more, making them the largest living primates
