An attempt has been made in the present study to determine sex on the basis of metric observations pertaining to the cranio-facial region. A total of 150 adult completely dry crania (75 males and 75 females) were measured for eighteen measurements following standard craniometric technique, from various educational and medical institutes,Results of the present study reveal that there exists a highly significant sex difference in all the measurements (at 0,01% level)except for Palatal breadth and orbital height. The study suggests that metric observations are relatively more reliable than the non-metric ones.

Key Words: metric observations, Cranio-facial dimensions, sex differences
