Size of the Gorilla

wondering about the size of the gorilla? Gorillas are the largest living primates on Earth, and their impressive size is one of the most striking features travellers notice during gorilla trekking safaris. Seeing a gorilla up close especially a dominant silverback creates a powerful sense of awe. Understanding gorilla size helps explain their strength, movement, and social behavior. With Superfine Safaris Limited, guests gain deeper insight into these remarkable animals in their natural environment.

The adult silverback gorilla weighs between 140–220 kg (310–485 lbs) while teh adult female gorilla weighs between 70–100 kg (155–220 lbs).

Eastern Lowland Gorillas – Largest gorilla species; some males exceed 220 kg

Mountain Gorillas – Slightly smaller but bulkier with thicker fur

Western Lowland Gorillas – Smaller and lighter than eastern species

Cross River Gorillas – Smallest and rarest gorilla subspecies

Size of Baby and Young Gorillas

• Newborn gorillas weigh about 2 kilograms
• Infants cling closely to their mothers
• Growth is slow but steady over many years

How Tall Are Gorillas?

Gorillas rarely stand upright, but when they do, their height is remarkable.

• Adult male gorillas (silverbacks) can stand up to 1.7–1.8 meters tall
• Adult female gorillas typically reach 1.4–1.5 meters

Gorilla Body Length

From head to body (excluding limbs):

• Adult gorillas measure approximately 1.4–1.8 meters in length
• Males are longer and thicker than females

This compact but muscular body structure provides balance and strength.

Arm Span and Upper Body Size

A defining feature of gorilla size is their long arms.

• Gorilla arm span ranges from 2.3–2.6 meters
• Arms are longer and stronger than legs
• Designed for knuckle-walking, climbing, and foraging

Their powerful upper bodies allow gorillas to move efficiently despite their large size.

Chest and Shoulder Size

Silverbacks are known for their broad chest and shoulders.

• Chest circumference can exceed 2 meters
• Wide shoulders support heavy muscle mass
• Size alone helps establish dominance within the group

This physical presence often prevents conflicts without aggression.

Size Differences Between Male and Female Gorillas

• Males are almost twice the size of females
• Females are smaller, lighter, and more agile
• Mature males develop the distinctive silver hair on their backs

These size differences reflect different roles within gorilla families.

Why Gorillas Look Even Bigger

• Dense muscle mass (especially shoulders and arms)

• Thick chest and powerful neck

• Long arms adapted for knuckle-walking

• Upright posture when displaying dominance

How Gorilla Size Affects Movement

Despite their massive build, gorillas are surprisingly agile. they move using knuckle-walking, Juveniles and females climb trees frequently. Also, gorillas can move quickly over short distances when needed. Their size is balanced by flexibility and strength.

Why Gorilla Size Matters in the Wild

A gorilla’s size plays an important role in:

• Protecting the family group
• Establishing social hierarchy
• Reducing physical conflict

Large size, especially in silverbacks, often prevents confrontations without fighting.

Generally, gorilla size is one of the most defining characteristics of these gentle giants. From their towering height when standing to their wide chests and long arms, gorillas are built for strength, stability, and survival. Understanding how big gorillas are adds depth to any gorilla trekking safari and highlights the importance of conserving their forest habitats.
