how big is a full grown gorilla

An adult gorilla is roughly the size of a very short but extremely heavy, bodybuilder‑level human.

Quick Scoop

• Most full grown male gorillas (silverbacks) stand about 1.4–1.8 m tall (around 4 ft 7 in to 5 ft 11 in) when upright.

• Adult males usually weigh about 140–200 kg (300–440 lb), with some reaching close to 227 kg (500 lb) in the wild.

• Adult female gorillas are smaller, about 1.2–1.5 m tall (4–5 ft) and 70–120 kg (150–260 lb).

• Their arm span is huge: up to about 2.3–2.6 m (7 ft 7 in to 8 ft 6 in), so their arms are much longer than a human’s.

Gorilla	Typical height (upright)	Typical weight	Arm span
Adult male (silverback)	1.4–1.8 m (4 ft 7 in–5 ft 11 in)	140–200+ kg (300–440+ lb)	Up to 2.3–2.6 m (7 ft 7 in–8 ft 6 in)
Adult female	1.2–1.5 m (4–5 ft)	70–120 kg (150–260 lb)	Proportionally shorter than males

You can imagine a full grown male gorilla as about as tall as an average man but often twice the weight, with massively broad shoulders and arms that can reach about as wide as a small car is long.

TL;DR: A full grown gorilla is around 4.5–6 ft tall, 300–500 lb, and has an arm span close to 8 ft, making it the largest living primate.
