A fully grown gorilla is roughly human-height but far bulkier, heavier, and more powerfully built than almost any person.

Quick size snapshot

  • Adult male gorilla (silverback): about 4.5–6 feet (1.4–1.8 m) tall when standing upright.
  • Average adult human: about 5'4"–6'0" (1.63–1.83 m) tall.
  • Gorilla weight: roughly 300–485 lb (135–220 kg) for males in the wild; females about 150–250 lb (68–113 kg).
  • Human weight: many adults fall around 130–200 lb (59–91 kg), depending on sex and population.

So in height, a big male gorilla overlaps with tall humans, but in weight and thickness it’s often about twice as heavy as an average man, with much broader chest, shoulders, and arms.

Build and proportions

  • Gorillas have massive chests, thick necks, and extremely muscular arms, giving them a blocky, “tank‑like” profile.
  • Their arm span can reach about 7.5–8.5 feet (2.3–2.6 m), much wider than most human wingspans.
  • Humans are more leg‑dominant and upright, with relatively slimmer torsos and longer legs, so we look taller and narrower even when the standing height is similar.

A good mental picture: imagine someone your height, but with the mass and width of two very strong people fused together, plus arms that hang lower and much thicker through the shoulders and back.

Wondering how big is a gorilla compared to a human? Gorillas are about human-height but often twice the weight, with far broader shoulders and much greater muscle mass, making them look and feel enormous next to us.
