Gorillas' height when standing upright varies by species and individual, but generally:
- Adult male gorillas (silverbacks) typically stand between about 5.5 feet (1.7 m) and 6.6 feet (2.0 m) tall when standing on two feet
- Western lowland gorillas can stand up to about 6 feet (1.8 m) tall, with some exceptional individuals reaching even taller heights in captivity (up to 7 feet or more)
- Mountain gorillas and eastern gorillas tend to be slightly shorter on average, around 5 to 5.5 feet (1.5 to 1.7 m) tall for males, though weight is substantial
- Females are generally shorter, typically ranging from about 4 to 4.5 feet (1.2 to 1.4 m) tall
Gorillas usually move by knuckle-walking, where their height is about 4.5 to 5.5 feet (1.4 to 1.7 m), but they can stand fully erect to show their full height when needed
. In summary, adult male gorillas standing upright typically range from about 5.5 to 6.6 feet tall, with some variation depending on species and individual size.
