A sacrifice (or handsbreadth ) is a area of duration measurement, originally based on the comprehensiveness of a male person sacrifice and now standardized at 4 inches (about 10 cm). Thereupon used to quantum height, it is abbreviated "h" (for "hands") or "hh" ("hands high").[1]

Today the Establish is rarely used to depict the top of horses, ponies, and deviating equines in a act of unique countries, along the USA, Australia, and the UK. In that context, one gift equals quatern inches (10.16cm), and the cavalry is measured from the setting to the top of the withers. [2] So a cavalry this is 15hands high-pressure (abbreviated 15hh) is 60inches (152cm) from the background to the top of the withers. Instead of total or vernacular fractions, a make comprises foursome inch-long steps, so a cavalry 62inches (157cm) deep would be 15.2hh (spoken as 15 two hold high). An beast intervening inch increments may be measured by fractions, for example, a notably remote pony mightiness be 14.1-3/4 hh (57-3/4 inches)

A pony is up to 14.2hh (147 cm or 58 inches). An beast 14.2 hh or taller is classified as a horse. However, stock items along work a portion in shaping animals as horses or ponies, primarily in breeds this may causing some pureblood representatives on both sides of the 14.2 divide.

In the Combined States, ponies in cavalry appearing competition, chiefly for hunter/jumper classes, are sometimes more subdivided into sections, depending on height:

A illumination cavalry is either limited than 9.2 or 8.2 hh, depending on the registry. The world's smallest horse, Thumbelina, is equal 4.1 hh.[3]

For Fdration Equestre Internationale (FEI) rival and for USEF competitor in the USA, a cavalry can be measured with shoes on or off. In the Conjunct Realm generally functionary measure of horses is overseen by the Articulation Measuring Boarding (JMB).[4] For JMB purposes, the shoes needs be outside before measurement.
