The spectacled bear size is small for a bear. Adult males are about 5 to 6.5 feet long and weigh 200 to 340 pounds. Females are much lighter, usually 130 to 180 pounds. Here is the full breakdown, in pounds and feet first.
Spectacled Bear Size Chart
| Measure | Adult Male | Adult Female |
|---|---|---|
| Body length | 5–6.5 ft (1.5–2 m) | Slightly shorter |
| Shoulder height | 30–32 in (76–81 cm) | Slightly lower |
| Weight | 200–340 lb (91–154 kg) | 130–180 lb (60–82 kg) |
| Cub birth weight | About 10.5 oz (300 g) | About 10.5 oz (300 g) |
| Lifespan in captivity | 20–25 years | 20–25 years |
Spectacled Bear Height and Length
Spectacled Bear Length (Head to Tail)
How long is a spectacled bear? Adults measure about 5 to 6.5 feet from nose to rump. The tail is tiny, so it adds almost nothing.
Spectacled Bear Shoulder Height
How tall is a spectacled bear on all fours? About 30 to 32 inches at the shoulder. That is roughly the height of a kitchen counter, a bit lower than a large dog’s back.
How Tall Is a Spectacled Bear Standing Up?
Standing on its hind legs, an adult reaches roughly 5 to 6 feet. That is close to an average adult human. The bear rarely stands fully upright, though. It does so mostly to reach food or scan its surroundings.
Its build matches its lifestyle. It has a short, muscular neck and front legs longer than its back legs. This body shape makes it a strong tree climber.
Skull and Facial Profile Size
The skull is large for the bear’s body, but the face is short. It is a trait linked to its extinct short-faced bear relatives. The jaws are strong and the molars are wide and flat. They are built to grind tough plants like bromeliads, bark, and orchid bulbs.

Spectacled Bear Weight
Adult Male Spectacled Bear Weight
How much does a male spectacled bear weigh? Usually 200 to 340 pounds. A few exceptional males have been recorded near 385 pounds.
Adult Female Spectacled Bear Weight
How much does a female spectacled bear weigh? Usually 130 to 180 pounds. Females rarely go above that. A big female weighs about as much as a large adult man.
Spectacled Bear Cub Size and Growth
A newborn spectacled bear cub is tiny. Here is a simple growth timeline:
- Birth: about 10.5 ounces (300 g), eyes closed
- 1 month: eyes open
- 6 months: about 22 pounds (10 kg)
- 8–12 months: the cub stays with its mother, often riding on her back
The cub already shows the pale “spectacle” markings at birth.
Wild vs Captive Weight
Most precise weights come from zoo bears, because weighing a shy wild bear is hard. Wild bears also change with the seasons. They gain weight when fruit is abundant and lose it when food is scarce. Data on wild bears is still limited, so treat all ranges as estimates.

Spectacled Bear Size Compared to Other Animals
Spectacled Bear vs American Black Bear
Black bears are the most familiar bear in the USA. Adult males commonly weigh about 150 to 300 pounds, and some grow far larger. The spectacled bear is close to a small black bear in size. Both eat mostly plants.
Spectacled Bear vs Sun Bear
The sun bear is the smallest bear, at roughly 60 to 150 pounds. That makes the spectacled bear the second smallest.
Spectacled Bear vs Brown Bear (Grizzly)
Brown bears typically weigh 300 to 850 pounds. Coastal giants like the Kodiak can pass 1,000 pounds. A big brown bear can weigh three times or more what a large spectacled bear does.
Spectacled Bear vs Polar Bear
Adult male polar bears weigh about 770 to 1,500 pounds. That is the largest land carnivore on Earth. A polar bear can outweigh a spectacled bear by four to seven times.
Spectacled Bear vs Giant Panda
Giant pandas weigh about 220 to 330 pounds. They are close to a large spectacled bear in weight. Both are mostly plant eaters, though the panda is far more specialized.
Spectacled Bear vs an Average Adult Human
The average US adult man weighs about 200 pounds and stands about 5 feet 9 inches. A big male spectacled bear can weigh more than that. On all fours, though, it is much lower to the ground.
The spectacled bear’s extinct relative, the giant short-faced bear, was far bigger. Estimates put it well over 1,000 pounds.

What Affects Spectacled Bear Size?
Male vs Female Size Differences
Sex is the biggest factor. Males can be up to 50% heavier than females. This is why any single “average” weight can mislead.
Habitat, Altitude and Diet
These bears live in cloud forests, high-altitude grasslands (páramo), and even dry scrub. Their range runs from about 600 feet to 14,000 feet. Food changes with place and season. They eat fruit, bromeliads, cacti, honey, and bark. Better food means better body condition.
Conservation Status and Why Size Matters
The IUCN lists the spectacled bear as Vulnerable, and its numbers are decreasing. WWF estimates about 6,000 to 10,000 bears in the Northern Andes alone. The main threats are habitat loss and hunting.
