How do draft horses differ from ponies and light horses?

Domesticated horses are generally categorized into three types based on their size and build: draft horses, light horses, and ponies.12

• Draft Horses: Also known as heavy horses, these are bred for their strength to pull heavy loads, such as farm equipment or wagons. They are characterized by a heavy-limbed, powerful build, typically standing at least 16 hands high and often weighing more than 725 kg (1,600 pounds). Well-known breeds include the Belgian, Clydesdale, Percheron, and Shire.314
• Light Horses: These are intermediate in size and are primarily used for riding and equestrian sports like dressage, show jumping, and racing.31
• Ponies: By convention, these are horses that stand under 14.2 hands high. They are often noted for their endurance and gentle temperament, making them popular as pack animals or mounts for children.513
