Hand (unit) divided by four, then the remainder is added after the radix point. Thus, a horse that measures 60 inches is 15 hands high (15 x 4 = 60) and a horse halfway between 15 and 16 hands is 15.2 hands, or 62 inches tall (15 x 4 + 2 = 62) Because the subdivision of a hand is a base 4 system, a horse 64 inches high is 16.0 hands high, not 15.4. A designation of "15.5 hands" is not halfway between 15 and 16 hands, but rather reads 15 hands and five inches, an impossibility in a base 4
Pinto Horse Association of America Animals which measure no more than 34 inches at the withers (8.2 hands high) are classified as "Miniature"; between 34 and 38 inches (8.2 to 9.2hh) as "Miniature B"; 38 to 56 inches (9.2 to 14hh) as "Pony" and anything exceeding 14 hands high at the withers fits into the PtHA's "Horse" category. Pleasure-type Pintos are suitable for pleasure riding and are typically of Arabian, Andalusian or Morgan breeding and conformation.
