How big is a pizzly bear? An adult pizzly bear usually weighs about 500 to 1,000 pounds. It measures about 6.5 to 10 feet long. It stands about 6 to 8 feet tall on its hind legs. These are estimates, not official numbers, because scientists have measured very few wild hybrids. Here is the full breakdown.
Average Pizzly Bear Size Chart
| Measurement | Estimated Adult Range |
|---|---|
| Weight | 500–1,000 lb (230–450 kg) |
| Length | 6.5–10 ft (2–3 m) |
| Shoulder height | 3.3–5 ft (1–1.5 m) |
| Standing height | 6–8 ft (1.8–2.4 m) |
What Is a Pizzly Bear?
A pizzly is a polar-grizzly hybrid. It has a polar bear parent and a grizzly parent. A hunter shot the first confirmed wild one in 2006 on Banks Island in Canada’s Northwest Territories, and DNA tests proved it was a hybrid. Melting sea ice is pushing both parent species into the same areas, so more meetings are likely.
Pizzly Bear Height & Length
How Tall Is a Pizzly Bear Standing Up?
A pizzly bear stands about 6 to 8 feet tall on its hind legs. A tall NBA player is about 7 feet. Bears stand up to sniff the air and look around. They do not do it to attack.
Pizzly Bear Shoulder Height on All Fours
Shoulder height is the measure from the ground to the top of the shoulder hump. For a pizzly bear, it is about 3.3 to 5 feet. This is the number to use for fences, doors and trail cameras.
How Long Is a Pizzly Bear?
The pizzly bear length is about 6.5 to 10 feet from nose to tail. Many hybrids have a shoulder hump like a grizzly. They often have a longer neck and a narrower head, like a polar bear.
Pizzly Bear Weight
Average Pizzly Bear Weight (Males vs. Females)
The average pizzly bear weight sits near the top of the grizzly range and below the polar bear range. Adult males are often heavier than 700 pounds. Females are lighter. A hybrid’s weight depends heavily on which parent it takes after.
Pizzly Bear Cub Size & Growth
Both parent species give birth to cubs weighing about 1 pound. Hybrid cubs are likely similar. Hardly any growth records exist for wild hybrid cubs, so no one has a reliable growth chart.
Seasonal Weight Changes
Bears gain and lose weight with the seasons. Grizzlies eat heavily in fall and can lose up to about 30% of their body weight while denning. Polar bears gain fat on the sea ice and slim down when it melts. A pizzly’s weight likely swings too.
What Affects Pizzly Bear Size?
Genetics: First-Generation vs. Later Hybrids
A first-generation hybrid often looks like a mix of both parents. Later hybrids can lean toward one parent. A 2010 bear in Canada was the offspring of a hybrid and a grizzly. This proved that pizzlies can breed, and it also means their sizes vary widely.
Diet, Habitat & Climate Change
Polar bears live mostly on seals. Grizzlies eat salmon, berries, roots and land animals. A pizzly may eat both types of food. Climate change shrinks sea ice, forces food shortages and pushes the two species together.
Wild vs. Captive Pizzly Bears
Zoos have bred hybrid bears for decades. Zoo bears often get steady meals, so they can weigh more than wild ones. Wild pizzlies are rare and hard to weigh, which is why firm data is so thin.
Pizzly Bear Size Compared to Other Animals
Pizzly Bear vs. Polar Bear Size
The polar bear is the largest land carnivore. Adult males weigh about 770 to 1,320 pounds, and the biggest on record reached 2,209 pounds. A pizzly is usually smaller.
Pizzly Bear vs. Grizzly Bear Size
Male grizzlies weigh about 400 to 790 pounds. A pizzly often matches or beats a grizzly, but it rarely passes a large polar bear.
Pizzly Bear vs. Kodiak Bear & Black Bear
Kodiak bears are a giant brown bear subspecies. Males can reach about 1,500 pounds, so a Kodiak can outweigh a pizzly. A pizzly is much bigger than an American black bear, which usually weighs 200 to 600 pounds.
Pizzly Bear vs. Human, Lion & Tiger
The average US adult man weighs about 200 pounds, so a pizzly can weigh 2.5 to 5 times as much. A male lion weighs about 330 to 550 pounds. A big male Siberian tiger can reach about 660 pounds. A large pizzly can outweigh both.
FAQ’s About Pizzly Bear Size
How big is a pizzly bear?
An adult pizzly bear weighs about 500 to 1,000 pounds. It is about 6.5 to 10 feet long.
How tall is a pizzly bear?
A pizzly bear stands about 6 to 8 feet tall on its hind legs. On all fours, its shoulder height is about 3.3 to 5 feet.
How much does a pizzly bear weigh?
Most estimates put an adult pizzly bear between 500 and 1,000 pounds. Males weigh more than females.
Is a pizzly bear bigger than a grizzly bear?
Often yes, but not always. A pizzly usually matches or slightly beats a typical grizzly in weight.
Are pizzly bears bigger than polar bears?
Usually no. Most pizzlies are smaller than a large male polar bear, which can weigh over 1,300 pounds.
How big is a pizzly bear cub?
A pizzly cub likely weighs about 1 pound at birth, like both parent species. Growth data for hybrid cubs is very limited.
