Quick Scoop: Silverback Gorilla Weight

  • Most adult silverbacks: 300–485 lb (135–220 kg).
  • Some especially large males can reach about 500–600 lb (227–270 kg) , particularly in captivity where food is abundant and movement is lower.
  • Females are much lighter, usually around 150–250 lb (70–115 kg).

So if you picture a silverback, think of a compact, muscle‑packed body roughly twice the weight of an average adult man , built for climbing, defending the troop, and smashing through dense forest.
