The present study aimed to evaluate the morphometric indexes for Campolina stallions, gelded and mare horses, as well as morphologically characterizing them. For this purpose linear measurements from 4.840 stallions, 19.037 mares and 1371 gelded horses were used, obtained from ABCCCampolina's stud book database, from which nine morphometric indexes were calculated from six linear measurements. Analysis of variance was carried out to evaluate the effect of sex and age on the indexes obtained. We found that both factors influenced the morphometric index. Stallions have presented higher estimate body weight values than mares and gelded horses. According to the pectoral index values all categories were classified as far from the ground. According to body index and dactyl thoracic index average values, stallions and gelded horses were classified as medium lined and middleweight, respectively, once the mares were classified as more compact and overweight. It is concluded that Campolina stallions and gelded horses fall within the breed standard for saddle animals, but mares don't. However, the compact indexes 1 and 2 showed contradictory results and need to be better evaluated for its intended use in classifications. For most indexes gelded animals showed better proportion than the other categories.
