Gorillas are the largest living primates, with adult males, especially silverbacks, typically standing between about 1.7 to 1.8 meters (5.6 to 5.9 feet) tall when standing upright

. Some sources note that mature male gorillas can reach heights up to around 2.2 meters (7 feet 3 inches) in captivity, with the tallest wild gorilla recorded at 1.95 meters (6 feet 5 inches)

. Female gorillas are generally smaller, standing around 1.25 to 1.5 meters (4 feet 1 inch to 4 feet 11 inches) tall

. Mountain gorillas, a subspecies, have males that measure about 1.7 meters (5 feet 5 inches) tall on all fours, with females around 1.5 meters (4 feet 9 inches)

. Eastern lowland gorillas tend to be the tallest subspecies, often exceeding 1.75 meters (5 feet 9 inches)

. In summary:

• Adult male gorillas: approximately 1.7 to 1.8 meters (5.6 to 5.9 feet) tall upright, with some individuals taller
• Adult female gorillas: approximately 1.25 to 1.5 meters (4 feet 1 inch to 4 feet 11 inches)
• Tallest recorded wild gorilla: about 1.95 meters (6 feet 5 inches)
• Captive males can be taller, up to 2.2 meters (7 feet 3 inches)

These heights vary by species and individual, with gorillas usually walking on all fours, so their full height is most visible when standing upright briefly
