There are many breed societies for the Gypsy horse, with variations in their respective breed standards. The range of desired heights is generally from 13 to 16 hands (52 to 64 inches, 132 to 163 cm) in the United States and Australasia, but in Ireland and continental Europe, the desired height limit goes up to 16. 2 hands (66 inches, 168 cm) for some types and they permit both lighter-boned as well as larger horses than typically desired by the American organisations. [b] Some stud-books have different categories: The Gypsy Horse Registry of America has two height classifications: Section A for purebred horses under 14. 2 hands (58 inches, 147 cm) and Section B for purebred horses 14. 2 hands (58 inches, 147 cm) and over. Its Section C is for Gypsy Crossbred horses. The Netherlands stud-book for Gypsy horses, the Nederlands Stamboek voor Tinkers, identified there as the “Tinker horse,” classifies horses into three groups: “cob,” “vanner,” and “grai,” based on height in metres and degree of refinement. The cob type is approximately 14. 3 to 15. 1 hands (59 to 61 inches, 150 to 155 cm), and the vanner 15. 1 to 16. 2 hands (61 to 66 inches, 155 to 168 cm). The more refined “grai” may be of any size but is typically within the 14. 3- to 16. 2-hand range.
