Key Points:

  • While the average height of a horse ranges between around 55-71 inches, Sampson was no average horse — growing to over 3,000 lbs and 7 feet tall by the time he was four years old.
  • Shire is a breed of horses that is particularly large; however, it is not the only breed that can grow to enormous sizes.

Discovering the Amazing World of Horses

Horses are majestic and versatile creatures, and some horse breeds are known for their incredible size! Many of the heaviest and tallest horses are used as draft and working horses. Others have gained recognition for their massive weight and height alone. For instance, the world’s largest recorded horse stood 85 inches high and weighed more than some car models do today!

The average height of a horse ranges between 13.3 and 17.3 hands, which is between 55.12 and 70.87 inches. In addition, horses can weigh between 660 and 2,200 pounds. However, these figures are a generalization based on all breeds of horses. Size can depend 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 has a height that ranges from eight to 14 hands. Other height and weight averages for large horse breeds are described in other sections below.

The Biggest Horse in the World

Sampson is the name of the biggest horse on record. This Shire horse was born in 1846 in the county of Bedfordshire in England. Sampson weighed in at 3,360 pounds when he was just four years old! By comparison, many cars don’t even weigh that much. For instance, a 2022 Honda Civic weighs between 2,877 and 3,077 pounds, depending on the model. Sampson was reported to be over seven feet tall, or 21.25 hands, too. As you can see in the picture below, due to his unbelievable size, Sampson rightfully earned the nickname “Mammoth.”

Why are Horses Measured in Hands?

Przewalski’s horses are bulky and only reach a max height of fourteen hands.


Horses are measured in hands because in ancient times there were no units of measurement apart from the human body. Feet, inches, meters, yards, and other units of measurement did not exist as they do today. Therefore, people used their hands to measure the height of horses. Why did they need to measure a horse’s height, to begin with? Height measurement was necessary for buying and selling. A buyer would want to know how tall a horse was before purchasing it for riding or working purposes.

Using the hand as a unit of measurement became problematic, though, because no human hand measures the same length. Therefore, King Henry VIII determined that a better form of measurement was needed. He labeled the length of a “hand” as four inches. Therefore, if a horse is reported to be 16 hands in height, then it is 64 inches tall.

Horses are not measured head to toe, though. The head of the horse moves, so measuring a horse beginning at its head is unreliable in determining its true height. Thus, the horse is measured at the withers (shoulders), which are the first stable and stationary part of the horse at the top of its body. Then, a horse can be measured from the ground next to its hooves up to its withers.

The Shire Horse and Other Large Horse Breeds

The Shire breed originates in England and is a draft and farm animal. Shires stand at an average of 17 hands tall, or 5 feet 8 inches. While some Shires, like Sampson, are the exception and weigh more than the average, most weigh up to 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. Other massive horse breeds are described below.

The Suffolk Punch

Suffolk Punch horses are strong and tireless, making them the perfect farming horse. They also adapt well to a variety of environments and are known to be extremely agreeable breeds. Unfortunately, the Suffolk Punch is a critically endangered breed of horse, meaning that very few of these horses still exist today.


Biggest Horses: Clydesdales
The Clydesdales are often seen in parades.


Clydesdales weigh between 1,800 and 2,000 pounds and measure approximately 16 to 18 hands high. Clydesdales originated in Scotland and were used as draft and farm animals like the Shire horse. In fact, Clydesdales appear so similar to the Shire horse that it can be difficult to tell them apart. Like the Shire, Clydesdales have thick hair on their legs and have color variations within the shades of brown, black, and gray. Clydesdales are recognized as smart, adaptable, and peaceful creatures. You might recognize this breed from Budweiser beer ads, as they are the company’s mascot.

Belgian Horse

Biggest Horses: Belgians
The Belgians are one of the strongest drafts in the world.


Belgian horses weigh between 2,100 and 2,300 pounds on average and are 16.2 to 17 hands tall. They originate in Belgium and are characterized as a mighty, indefatigable breed. Belgian horses are best utilized as draft horses because they can move extremely heavy amounts of weight with ease. Belgian horses are mellow, smart, and reliable horses much like the Clydesdale.

They are smart animals, meaning they are trained easily. They usually appear as gray or black, and they are known as beautiful, adaptable, and gentle animals.

Characteristics and Abilities of Draft Horses

Draft horses are the heaviest and tallest type of horse, and these qualities aid them in working and carrying heavy loads. However, some draft horses can be used for riding and transportation, too. Many draft horses today engage in shows, competitions, or the pulling of carriages and wagons. For instance, the Amish use draft horses to pull their carriages and other loads. In New York City, carriage rides often found near Central Park are pulled by draft horses, too. Historically, draft horses have made important contributions. By working on farms, carrying supplies in warfare, and transporting numerous people across landscapes, draft horses have worked to supply resources and develop countries in a manner crucial to human success. Although they may look intimidating due to their massive size, draft horses are kind animals. They are also loyal to their owners and easily trained.

Other Famously Huge Horses

While no horse rivals the size of Sampson, some other famously giant horses have been recorded throughout history. Below list of some of the largest horses of all time.

  • Morocco was the name of a Percheron-Arabian horse, who measured 21.2 hands in height and weighed 2,835 pounds. Morocco was a popular horse, appearing at St. Louis World’s Fair in 1904. In addition, he was known as a gentle and fun-loving horse, attracting many women and children.
