American bison size: How big do they get?

How big does a American bison get? Here is an overview over the average adult age:

A grown American bison (Bison bison) reaches an average size of 2.85 meter (9′ 5″).

When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 33 years, they grow from 20 kg (44.09 lbs) to 622.29 kg (1371.91 lbs). Talking about reproduction, American bisons have 1 babies about 1 times per year. The American bison (genus: Bison) is a member of the family Bovidae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a American bison is  (9' 5

The American bison or simply bison (Bison bison), also commonly known as the American buffalo or simply buffalo, is an American species of bison that once roamed North America in vast herds. Its historical range, by 9000 BCE, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York and south to Georgia and, according to some sources, down to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. It nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was down to 541 animals by 1889. Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 31,000 animals today, largely restricted to a few national parks and reserves. Through multiple reintroductions, the species is now also freely roaming wild in some regions in Yakutia as well as Mexico.Two subspecies or ecotypes have been described: the plains bison (B. b. bison), smaller in size and with a more rounded hump, and the wood bison (B. b. athabascae)—the larger of the two and having a taller, square hump. Furthermore, the plains bison has been suggested to consist of a northern plains (B. b. montanae) and a southern plains (B. b. bison) subspecies, bringing the total to three. However, this is generally not supported. The wood bison is one of the largest wild species of bovid in the world, surpassed by only the Asian gaur and wild yak. Among extant land animals in North America, the bison is the heaviest and the longest, and the second tallest after the moose.Spanning back many centuries, Native American tribes have had cultural and spiritual connections to the American bison. It is the national mammal of the United States of America.
