Wolves are large canids with considerable size variation depending on subspecies and geography.
- Length and Height: Adult wolves typically measure between 105 and 160 cm (41 to 63 inches) in body length, with an additional tail length of 29 to 50 cm (11 to 20 inches). Shoulder height averages around 80 to 85 cm (31 to 33 inches)
- Weight: The average wolf weighs about 40 kg (88 lbs), but weights range widely. Smaller wolves, like the Arabian wolf, weigh around 25 kg (55 lbs), while larger subspecies such as the Eurasian or Mackenzie wolves can weigh between 69 and 79 kg (152 to 174 lbs). Exceptionally large individuals have been recorded up to 79.4 kg (175 lbs), with some reports of wolves weighing over 90 kg (200 lbs) though these are rare
- Regional Differences: Wolves in northern latitudes tend to be larger, consistent with Bergmann's rule. For example, European wolves average about 38.5 kg (85 lbs), North American wolves about 36 kg (79 lbs), and Indian or Arabian wolves are smaller at about 25 kg (55 lbs)
- Comparison to Humans and Other Canids: Wolves can be up to 6 to 7 feet long including the tail, roughly the height of an adult human when standing on hind legs. They are about twice the size of coyotes, with larger and blockier muzzles and bigger paws
In summary, a typical adult wolf stands about 2.5 to 2.8 feet tall at the shoulder, measures about 3.5 to 5.3 feet in body length (excluding tail), and weighs between 40 and 80 kg (88 to 175 lbs), with some exceptional individuals larger than this range
