In horse racing, these definitions may differ: For example, in the British Isles, Thoroughbred horse racing defines colts and fillies as less than five years old. However, Australian Thoroughbred racing defines colts and fillies as less than four years old.
• Size and measurement
The height of horses is measured at the highest point of the withers, where the neck meets the back. This point was chosen because it is a stable point of the anatomy, unlike the head or neck, which move up and down.
The English-speaking world measures the height of horses in hands and inches. One hand is equal to 4 inches (101.6 mm). The height is expressed as the number of full hands, followed by a point, then the number of additional inches, then the abbreviation "h" or "hh" (for "hands high"). Thus, a horse described as "15.2 h" is 15 hands (60 inches, 152 cm) plus 2 inches (5.1 cm), for a total of 62 inches (157.5 cm) in height.
