Adult gorillas standing upright vary in height depending on species and sex:
- Western lowland gorillas: Adult males stand up to about 6 feet (1.8 meters) tall, while females reach up to 4.5 feet (1.4 meters)
- Silverback gorillas (adult male mountain gorillas): Typically stand between 5.6 to 6 feet (1.7 to 1.8 meters) tall
- Mountain gorillas (males): Range from about 4 to 6 feet (1.2 to 1.8 meters) tall, females slightly shorter at 3.5 to 5 feet (1 to 1.5 meters)
- The tallest recorded wild gorilla was a silverback measuring 6 ft 5 in (1.95 m), while captive gorillas can be even taller, e.g., one reached 7 ft 3 in (2.2 m)
Gorillas generally have longer arms than legs and spend most of their time knuckle-walking, so standing upright is less common and usually brief. When standing, adult male gorillas are typically around 5.5 to 6 feet tall, making them taller than the average human male
. In summary, an adult male gorilla standing up is roughly between 5.5 and 6 feet tall, depending on the subspecies and individual variation.
