A wolf's size is dependent on its species, and male wolves typically weigh 20 percent more than the females. Arabian wolves, which are considered the smallest wolves in the world, weigh approximately 30 pounds, while gray wolves, which are considered as one of the largest wolf species, weigh between 85 to 115 pounds, with some pack members occasionally reaching 130 pounds.
The average height and length of wolves will also be dependent on their species. Female gray wolves average 4.5 to 6 feet, while males are an average of 5 to 6.5 feet. In comparison, male and female adult red wolves average 4.5 to 5.5 feet. Gray wolves typically stand at a shoulder height of 2.6 to 3.2 inches, while red wolves average 26 inches.
