A fully grown silverback gorilla typically weighs between 135 to 195 kilograms (300 to 430 pounds) and stands about 1.5 to 1.8 meters (4 feet 11 inches to 5 feet 11 inches) tall when standing upright. Their arm span ranges from 2.3 to 2.7 meters (7 feet 7 inches to 8 feet 10 inches), which is significantly longer than their height
. Some sources note that the heaviest silverbacks can weigh up to around 270 kilograms (about 600 pounds), and the tallest recorded wild silverback was about 1.95 meters (6 feet 5 inches) tall with an arm span of 2.7 meters (8 feet 10 inches)
. In captivity, some males have grown even larger, reaching heights of over 2 meters (7 feet 3 inches)
. In summary, a full-grown silverback gorilla is roughly:
- Height: 1.5 to 1.8 meters (5 to 6 feet)
- Weight: 135 to 195 kilograms (300 to 430 pounds), sometimes up to 270 kilograms (600 pounds)
- Arm span: 2.3 to 2.7 meters (7.5 to 9 feet)
These dimensions make silverback gorillas the largest living primates and incredibly powerful animals
