Mean facial depth distance of a balanced face was introduced and the relationship with anterior facial height was investigated. The distance between the projections of Condylion (Co’) and Nasion (N’) points on Frankfort Horizontal plane was defined as facial depth distance and this distance was compared with anterior facial height to identify a proportion. The lateral cephalometric radiographs of 1061 individuals (577 female, 484 male) with skeletally class-I (0°≤ANB≤4°) relationship and vertically normal according to the Jaraback proportion (62%≤S-Go/N-Me≤65%) were selected for the study. The two gender groups were divided into four subgroups according to their periods of growth and development. Due to identify the term of ‘’normal’’ in facial depth distance, the relation between the facial depth distance (Co’-N’) and the anterior facial height (N-Me) was examined separately in each group. A proportion of 69,32±4,15% was found between the facial depth distance and the anterior facial height. Besides, gender did not affected this proportion and age depended relation was found insignificant. Using this proportion could facilitate the detection of the facially balanced individuals.
