Others have gained recognition for their massive size alone. Sampson, later known as Mammoth, was one such horse.

The average height of a horse ranges between 13.3 and 17.3 hands, which is between 55.12 and 70.87 inches. Additionally, horses can weigh between 660 and 2,200 pounds. However, these figures are a generalization based on all horse breeds. Size depends on several factors, including diet, genetics, and exercise. Therefore, different horse breeds have different average heights and weights. For instance, while the Arabian horse measures between 14.1 and 15.1 hands on average, the spotted pony’s height ranges from 8 to 14 hands.

Sampson is the name of the largest horse ever recorded. This Shire horse was bred by Thomas Cleaver and foaled in 1846 in the county of Bedfordshire, England. Sampson weighed 3,359 pounds when he was only four years old. By comparison, this is slightly heavier than a typical four-door sedan. Sampson was reported to be over seven feet tall, or 21.25 hands. As of 2025, Sampson remains the Guinness World Record holder for the tallest horse.

While some Shires, like Sampson, weigh more, most weigh no more than 2,000 pounds. Shires also have an abundance of hair on their legs, and their color is usually a shade of black, brown, or gray, with white feet.

The second-largest horse ever recorded was Big Jake. He was an American Belgian gelding who stood slightly over 20 hands tall (approximately 6 feet 10.75 inches) and weighed around 2,600 pounds. Big Jake was recognized by Guinness World Records as the tallest horse living from January 19th, 2011, until his death at age 20 in June 2021. He was foaled in March 2001.
The American Belgian has a relatively small, well-shaped head, clean flat bones, and strong muscling compared to its European forebears. Starting in the late 19th century, American breeders refined the imported European stock to create a horse with more sloped shoulders, elegant heads, and stylish movement. American Belgians are docile and make good farm horses.
