Gorillas are the largest living primates, with size varying by species, sex, and individual. Height:
- Adult male gorillas typically stand between 4 to 6 feet tall (1.25 to 1.8 meters) when upright
- Silverback males, the dominant adult males, average around 5 to 6 feet tall (1.5 to 1.8 meters), with some exceptional individuals recorded up to 6 ft 5 in (1.95 m) or even 6 ft 9 in (2.06 m)
- Females are generally smaller, standing about 4 to 5 feet tall (1.25 to 1.5 meters)
Weight:
- Adult male gorillas weigh between approximately 300 to 600 pounds (136 to 270 kg), depending on species and captivity status
- Eastern gorillas tend to be larger, with males weighing up to 484 pounds (220 kg) and females up to 215 pounds (97.7 kg)
- Western lowland males average around 169.5 kg (374 pounds), females about 71.5 kg (158 pounds)
- In captivity, males can be heavier, sometimes reaching over 310 kg (683 pounds)
Arm Span:
- Gorillas have very long arms, with spans ranging from about 2.3 to 2.7 meters (7 ft 7 in to 8 ft 10 in), longer than their height and longer than an adult human's arm span
In summary, adult male gorillas stand roughly 4 to 6 feet tall, weigh between 300 and 600 pounds, and have an arm span up to nearly 9 feet. Females are smaller in both height and weight. Eastern gorillas are generally larger than western gorillas
