The Alaskan tundra wolf is one of the largest wolves in North America, reaching up to 160 cm (5.2 feet) in body length and weighing as much as 80 kg (176 lbs).
This guide breaks down everything about Alaskan tundra wolf size — weight, length, height, and how it stacks up against other wolves.
What Is the Alaskan Tundra Wolf?
The Alaskan tundra wolf (Canis lupus tundrarum) is a subspecies of gray wolf. It’s also called the barren-ground wolf.
Naturalist Gerrit Smith Miller Jr. first described this wolf in 1912. He noted its skull and teeth closely match the Great Plains wolf, but with a narrower snout.
Alaskan Tundra Wolf Size at a Glance
- Length: 130–160 cm (head to body)
- Weight: 35–80 kg (males), 18–55 kg (females)
- Coat: Light or pure white, sometimes dark or black
- Build: Large frame with heavier teeth than most Alaskan wolve
- Standing at the shoulder : 76 to 86 cm
Where This Wolf Lives
The Alaskan tundra wolf roams the Arctic coastal tundra. Its range stretches from near Point Barrow eastward toward Hudson Bay, and likely up into the Arctic Archipelago.
This is a treeless, wind-battered landscape. Body size in this wolf is closely tied to survival here — bigger bodies hold heat better in extreme cold.

Alaskan Tundra Wolf Size Breakdown
Average Length
Most Alaskan tundra wolves measure 130 to 160 cm from nose to the base of the tail. That makes them among the longest wolf subspecies on the continent.
Average Weight: Males vs. Females
Male Alaskan tundra wolves are noticeably heavier than females. Males typically weigh between 35 and 80 kg. Females run smaller, usually 18 to 55 kg.
This weight gap between sexes is called sexual dimorphism, and it’s common across nearly all wolf subspecies.
Shoulder Height & Body Build
Standing at the shoulder, this wolf reaches roughly 76 to 86 cm — similar to a large domestic dog breed, but heavier and more muscular.
Alaskan Tundra Wolf Size Compared to Other Wolves
Alaskan Tundra Wolf vs. Interior Alaskan Wolf
The Interior Alaskan wolf (found in Denali and the Yukon) is closely related but has lighter teeth and a slightly smaller build. The tundra wolf’s heavier dentition helps it crack bone from large Arctic prey.
Alaskan Tundra Wolf vs. Arctic Wolf
The Arctic wolf (found further north in Canada’s high Arctic islands) is usually a bit smaller and stockier. Both wolves share a pale or white coat as camouflage.
Alaskan Tundra Wolf vs. Eurasian Tundra Wolf
The Eurasian tundra wolf (Canis lupus albus), found in Siberia and northern Finland, is a completely different subspecies. It’s smaller — males average 118 to 137 cm long and weigh around 40 to 49 kg. If an Siberia or reindeer herds, it’s talking about this wolf, not the Alaskan one.
Alaskan Tundra Wolf vs. Gray Wolf (Overall Species)
Compared to the gray wolf species as a whole, the Alaskan tundra wolf sits at the larger end of the size range. Many gray wolf subspecies average 100–130 cm in length, making the tundra wolf noticeably bigger.

How Big Is an Alaskan Tundra Wolf Compared to a Human?
An adult Alaskan tundra wolf can rival a small adult human in length. At 160 cm long, it’s close to the height of an average adult woman — though the wolf’s body runs horizontal, not vertical.
Standing Height vs. a Human
At the shoulder, this wolf stands about waist-high on most adults. That’s tall for a wild canine — for comparison, a Labrador Retriever stands around 55–62 cm at the shoulder.
FAQs About Alaskan Tundra Wolf Size
How big is an Alaskan tundra wolf compared to a German Shepherd?
It’s notably larger. A German Shepherd averages 30–40 kg, while this wolf can weigh up to 80 kg.
What is the average weight of an Alaskan tundra wolf?
Males average around 35–80 kg. Females average 18–55 kg.
Is the Alaskan tundra wolf the largest wolf subspecies?
It’s among the largest in North America, but the Northwestern wolf and Mackenzie Valley wolf are close rivals in size.
Do Alaskan tundra wolves get bigger than Interior Alaskan wolves?
Yes, generally. The tundra wolf tends to have a larger frame and heavier teeth than its interior cousin.
How long do Alaskan tundra wolves get, nose to tail?
Body length alone runs 130–160 cm, not counting the tail, which adds extra length.
Conclusion
The Alaskan tundra wolf stands out as one of North America’s biggest wolves — built heavy, long, and pale to survive the open Arctic tundra. Its size comes down to sex, climate, and prey, not chance. Whether you’re comparing it to a Eurasian tundra wolf, an Interior Alaskan wolf, or a family dog, this Arctic hunter simply outsizes most of them.
