Quick answer
Adult giant pandas typically weigh about 70–120 kg (155–265 lb). They are bears, not polar bears. IUCN lists them Vulnerable (2016); China followed in 2021. The Fourth National Survey counted 1,864. Figures checked 13 August 2026.
How heavy are adult giant pandas?
Treat 70–120 kg as the usual adult planning range. Head-body length and live weights do not always match museum skins. “Herbivore size note” without the Vulnerable date was the thin version of this page.
Do males and females differ?
Males are often heavier. Cubs are tiny at birth and take years to reach adult mass. Nutrition on a bamboo slope sets the ceiling within genetic limits — not a polar-bear growth chart.
Why does size matter?
A carnivore gut on a 100 kg frame forces almost constant feeding. Isolated mountain blocks in Sichuan, Shaanxi and Gansu can trap a panda on the wrong slope when a stand flowers and dies. Wild lives often run about 15–20 years.
How do researchers weigh them?
Live weights are hard to take. Morphometrics, cameras and carcass data fill gaps. Tourist guesses are not the Fourth National Survey. Captive ledgers are separate from 1,864 wild animals.
Why so much bamboo for that body?
A short gut extracts little from cellulose, so adults eat typically 12–38 kg a day. The “pseudo-thumb” — an enlarged wrist bone — grips stalks. That is why a bamboo die-off is a conservation event, not a menu change.
Is a giant panda still a bear?
Yes — Ailuropoda melanoleuca, not a red panda and not a polar bear. About 99% of the diet is bamboo. WARN’s habitat appeal funds partner forest work — not Chengdu or Wolong.

Giant Panda FAQs
How big is a giant panda?
Adult giant pandas typically weigh about 70–120 kg (155–265 lb). They are bears, not polar bears — a polar bear is several times heavier. Size is why they must eat 12–38 kg of bamboo a day. IUCN lists them Vulnerable (2016); China followed in 2021. Figures checked 13 August 2026.
Are giant pandas as big as polar bears?
No. Polar bears are Arctic marine hunters; giant pandas are mountain bamboo specialists in Sichuan, Shaanxi and Gansu. Mixing the two produces a cartoon scale. A zoo cub’s weight is not a Fourth National Survey.
Does size tell you they are saved?
No. The Fourth National Survey (2011–2014) counted 1,864 pandas excluding cubs under 1.5 years. IUCN’s 2016 math used about 1,040 mature individuals. A heavy bear on a fragmented mountain is still conservation-dependent. WARN does not run Chengdu or Wolong.
What actually helps giant pandas?
Keep bamboo forest connected. World Animal Rescue Network funds habitat-protection partners — not Chengdu or Wolong panda bases.
