- Commonly, silverbacks stand around 5 feet (1.5 m) tall
- Some sources note an average height standing upright between 5.6 to 5.9 feet (1.7 to 1.8 m)
- Others report a range from about 5'5" to 6 feet tall
- Adult male gorillas (silverbacks) generally measure between 4 ft 7 in to 5 ft 11 in (1.4 to 1.8 m), with exceptional individuals recorded up to 6 ft 5 in in the wild and even taller in captivity
- Silverbacks can measure from about 1.5 to 1.8 meters (4 ft 11 in to 5 ft 11 in) tall, with arm spans of 2.3 to 2.6 meters
