When you think of pandas, you probably imagine gentle, bamboo-loving fluffballs. Grizzlies? They’re the big, burly ones that seem to tower over everything else in the forest. A grizzly is definitely bigger and heavier than a giant panda—most of the time, a grizzly stands taller at the shoulder and outweighs a panda by a lot.
But how much bigger, exactly? Well, let’s break down their height, weight, and body features so you can really picture these bears side by side.
You’ll also get a sense of how these two stack up against other bear species, just to put things in perspective.
Direct Size Comparison: Giant Panda vs Grizzly Bear
Grizzlies are much larger and heavier than giant pandas. The main differences show up in adult weight ranges, shoulder height, and some record-breaking brown bear sizes.
Average Weight and Height Differences
Giant pandas (Ailuropoda melanoleuca) usually weigh 150–300 pounds (68–136 kg) as adults. Males are heavier, closer to the upper end.
When a big panda stands on its hind legs, it reaches about 4 to 6 feet (1.2–1.8 m) tall.
Grizzly bears, a subspecies of the brown bear (Ursus arctos), tip the scales much higher. Adult male grizzlies often weigh 400–790 pounds (180–360 kg), with females coming in smaller.
A typical grizzly standing up can hit 6 to 8 feet (1.8–2.4 m) tall. Coastal brown bears, which are related to grizzlies, and some record-setting brown bears can get even bigger.
Picture it: a big grizzly can weigh as much as two to five pandas. That size difference really matters for strength, reach, and, honestly, how intimidating they look in the wild.
Body Structure and Features
A panda’s body is round and compact, built for chomping on bamboo all day. Powerful jaw muscles and big molars help them grind up tough plants.
Pandas have a unique wrist bone that acts almost like a thumb, letting them grip bamboo stalks. Their limbs are shorter and not as muscular as a grizzly’s.
Grizzlies, on the other hand, pack on a ton of muscle, especially around the shoulders. That hump on their back? It’s all muscle, perfect for digging.
They have long, curved claws for digging roots, hunting, or making dens. Grizzlies show off longer legs, a wider skull, and way more powerful front legs.
All of this makes them faster over short distances and much better at wrestling big prey or moving heavy stuff around.
Standout Measurements and Records
Some record-breaking brown bears (Ursus arctos), including grizzlies, have tipped the scales at well over 1,000 pounds (450+ kg), especially in coastal areas.
Most inland grizzlies are smaller, but some males have reached 800–900 pounds. That’s massive.
Pandas almost never go above 300 pounds, so even the biggest panda falls short of an average male grizzly.
Grizzlies also beat pandas when it comes to bite force and skull strength. Compare their paw size, reach, or shoulder height, and, well, grizzlies win almost every time.

How Grizzlies and Pandas Compare to Other Bears
Grizzlies and giant pandas land on very different parts of the bear size chart. Grizzlies are big, muscular brown bears with long claws.
Pandas are chunky, bamboo-eating bears that look almost small next to the biggest brown or polar bears.
Where Pandas and Grizzlies Rank Among All Bears
Grizzly bears (the North American brown bear) are among the largest bears you’ll find on land. Adult males usually weigh 400–790 pounds and stand about 3.5 feet at the shoulder.
Some coastal brown bears and a few inland grizzlies get even heavier. Females are smaller, usually between 200–450 pounds.
Giant pandas average 150–300 pounds and stand around 2–2.5 feet at the shoulder. That puts them closer in size to smaller brown bears or the biggest black bears, not the giant grizzlies.
So, by weight, one male grizzly can outweigh two or more adult pandas.
You could imagine the rankings like this: polar bears and the biggest brown or Kodiak bears at the top, then grizzly/brown bears, followed by black bears and pandas, and finally the smallest bears at the bottom.
Polar Bears, Kodiak Bears, and the Largest Bears
Polar bears (Ursus maritimus) take the crown for largest bear species. Adult male polar bears often weigh 900–1,600 pounds and can stand up to 10 feet tall on their hind legs.
Kodiak bears (Ursus arctos middendorffi), a brown bear subspecies, can match polar bears in size. Big male Kodiaks sometimes weigh over 1,400 pounds if food is plentiful.
If you’re just looking at size, these two—polar and Kodiak—are the real giants. Polar bears have longer bodies for swimming and thick layers of fat for warmth.
Kodiaks get huge from all the rich food along Alaska’s coasts. An inland grizzly, even a big one, will usually look smaller next to a Kodiak or a giant polar bear.
Black Bears, Sun Bears, and Smaller Bear Species
American black bears usually come in smaller and more varied sizes than grizzlies. Males can weigh anywhere from about 125 to 600 pounds, and their shoulders sit around 2 to 3.5 feet high.
Honestly, if you wander through many forests, you’ll spot black bears that look way more like pandas in size than those hulking grizzlies.
Sun bears? They’re the smallest of all bear species. Adult sun bears usually weigh between 60 and 145 pounds, and they rarely stand taller than 2 feet at the shoulder.
Other smaller bears, like the sloth bear and some tropical species, stay well below the size of brown or polar bears. These little guys climb trees with surprising skill and stick to different diets and habitats than the big, heavy bears most people picture.
