Adult gorillas standing fully upright are roughly about as tall as an average person, with big differences between males and females.

Quick Scoop

  • Adult male gorillas (silverbacks) usually stand about 5–6 feet tall upright (around 1.5–1.8 meters).
  • Adult female gorillas are shorter, typically around 4–5 feet tall (about 1.2–1.5 meters).
  • Some especially large males can reach a bit over 6 feet when fully stretched out.
  • Different subspecies (mountain, eastern lowland, western lowland, cross river) all sit in roughly this same range, with eastern lowland males among the tallest.

A quick mental picture

If you imagine a strong human adult between about 5'5" and a little over 6' tall, that’s the rough standing height range for most grown gorillas, but with a much bulkier, more muscular build and very long arms.

TL;DR: Standing up straight, most adult male gorillas are around 5–6 ft tall, and adult females are around 4–5 ft tall.
