250px-Percheron3Percherons generally stand between 16.2 and 17.3 hands (66 to 71 inches, 168 to 180 cm) high, although the breed has an outer range of 15 and 19 hands (60 to 76 inches, 152 to 193 cm). They average around 1,900 pounds (860 kg), although the top weight is around 2,600 pounds (1,200 kg). They are generally gray or black in coloring, although the American registry also allows the registry of roan, bay and chestnut horses. The British registry only allows horses of gray or black to be registered. Many horses have white markings on their heads and legs, but registries consider excessive white to be undesirable. The head has a straight profile, with a broad forehead, large eyes and small ears that reflect the breed's Arabian ancestry. The chest is deep and wide and the croup long and level. The feet and legs are clean and well muscled. They are described as proud and alert, and intelligent, willing workers. They are considered to be easy keepers and easy to work with and train. The breed adapts well to many different conditions and climates.
