Upright, gorilla males can reach 1.7 m on average. Western gorillas are the shortest subspecies with an average height of less than 1.7 m, whereas eastern lowland or Grauer's gorillas are the tallest subspecies with a height of 1.75 m or more. Mountain gorilla males' arms span 2.25 m and their chest measurement is 1.50 m.

Male western gorillas have a mean weight of 140-160 kg, male mountain gorillas 150-160 kg and male Grauer's gorillas 160-180 kg. Free-ranging gorillas weighing more than 200 kg are rare. Females usually weigh between 70 and 110 kg.
