How big is a grolar bear? A grolar bear usually weighs 400 to 1,100 pounds and measures 6.5 to 10 feet long. It stands about 3.5 to 5 feet tall at the shoulder. That puts the grolar bear size between a grizzly bear and a polar bear.
This polar-grizzly hybrid is rare, and only a handful of wild cases have been confirmed. So exact numbers are still estimates. Below, you’ll find the full grolar bear height, weight and length, plus how it stacks up against other animals.
Grolar Bear Size Chart
| Measurement | US Units | Metric |
|---|---|---|
| Height (at shoulder) | 40–60 inches | 102–152 cm |
| Weight | 400–1,100 lb (up to 1,500 lb in some sources) | 180–500 kg |
| Length (nose to tail) | 6.5–10 feet | 2–3 m |
| Lifespan | About 25 years | – |
| Top speed | About 25 mph | 40 km/h |
Grolar Bear Height
How tall is a grolar bear? On all fours, it stands about 40 to 60 inches at the shoulder. A grizzly stands near 3 feet, and a polar bear near 4 feet.
Standing on its hind legs, a grolar bear would likely reach 7 to 9 feet. This is an estimate based on both parent species, not a measured figure.
Grolar Bear Weight
How much does a grolar bear weigh? Most sources place it between 400 and 1,100 pounds. Some list a top weight near 1,500 pounds.
Why the gap? Each bear’s diet, home range and parentage change its weight. A bear raised on rich seal meat grows heavier than one living on berries and roots.
Grolar Bear Length
A grolar bear measures about 78 to 120 inches from nose to tail. That is 6.5 to 10 feet. The longer end of the range is rare.

How Big Do Grolar Bears Get?
How big do grolar bears get? Most stay well below the largest polar bears. A big adult is about the size of a large male grizzly, and a few may grow bigger.
Male vs. Female Grolar Bear Size
In both parent species, males are much larger than females. Experts expect the same pattern in hybrids. However, no study has yet measured enough hybrids to confirm exact male and female ranges.
Grolar Bear Cub Size and Growth
Polar and grizzly cubs are both tiny at birth, close to 1 pound. Grolar cubs are likely similar.
The best-known hybrid cubs were born at Osnabrück Zoo in Germany in 2004. After that, growth data for grolar bear cubs is very limited.
What Affects Grolar Bear Size?
Four things shape a grolar bear’s size:
- Parentage: Some hybrids lean toward the polar side, others toward the grizzly side.
- Diet: Seals and caribou build more bulk than plants.
- Habitat: Food supply differs between the Arctic coast and inland tundra.
- Generation: Second-generation hybrids carry mixed genes, so their size is harder to predict.

Grolar Bear Size Compared to Other Animals
Grolar Bear vs. Polar Bear Size
The polar bear is the largest land predator on Earth. A grolar bear is usually smaller. It also has a shorter neck and a body less built for ice.
Grolar Bear vs. Grizzly Bear Size
A grolar bear is generally bigger than a grizzly. Grizzly males average 400 to 800 pounds. A grolar bear often tops that.
Grolar Bear vs. Kodiak Bear Size
The Kodiak bear is the biggest brown bear. Top Kodiaks can match or beat a grolar bear in weight. Many grolar bears weigh a bit less.
Grolar Bear vs. Black Bear Size
The black bear is the bear most Americans see. A grolar bear can be two to four times heavier. Even a large black bear looks small beside one.
Grolar Bear vs. Humans and Everyday Objects
The average US man weighs about 200 pounds. A mid-size grolar bear weighs as much as three to five men. A 900-pound bear is close to the weight of a grand piano.

Grolar Bear Physical Features and Build
Body Shape, Hump and Skull
A grolar bear has a shoulder hump, but it is smaller than a grizzly’s. Its neck is longer than a grizzly’s and shorter than a polar bear’s. The skull also sits between the two.
Paws, Claws and Fur
The claws are longer than a polar bear’s but shorter than a grizzly’s. The soles are partly hairy. The fur is creamy white to light brown, often with brown patches around the eyes, legs and paws.
Speed, Swimming and Strength
A grolar bear can run about 25 mph over short distances. It is a weaker swimmer than a polar bear. Its long claws can also make walking on ice clumsy.
Hybrids are less specialized than either parent. As climate change pushes both species into shared areas, scientists expect more overlap, though hybrids will likely stay rare.

FAQ’s About Grolar Bear Size
How big is a grolar bear?
A grolar bear usually weighs 400 to 1,100 pounds and is 6.5 to 10 feet long. It stands 3.5 to 5 feet tall at the shoulder.
Is a grolar bear bigger than a grizzly bear?
Yes, in most cases. Grizzly males average 400 to 800 pounds, while a grolar bear is often heavier.
How tall is a grolar bear standing up?
A grolar bear likely stands 7 to 9 feet on its hind legs. This is an estimate based on its parent species.
How much does a grolar bear weigh?
Most weigh between 400 and 1,100 pounds. Some sources list up to 1,500 pounds.
Are grolar bears bigger than polar bears?
No. A grolar bear is typically smaller than a full-grown male polar bear, which can reach 1,500 pounds.
How big is a grolar bear cub?
Cubs are likely close to 1 pound at birth, like both parent species. Growth data on hybrid cubs is very limited.
Are grolar bears real, and how many exist?
Yes. The first wild hybrid was confirmed by DNA in 2006. Only a small number of confirmed cases exist, and hybrids can have cubs of their own.
Is a grolar bear the same as a pizzly bear?
Yes, both names describe a polar-grizzly hybrid. By common usage, “grolar” means a grizzly father and a polar bear mother. “Pizzly” is the reverse.
