Introduction Understanding facial harmony and proportions is essential for facial reconstructive procedures and orthognathic surgery planning. In the literature, the neoclassical facial canons have been revisited in populations including North American whites and African Americans. The purpose of this study was to establish a baseline for selected facial anthropometric measurements and test the validity of 3 neoclassical facial canons in a cohort of young Saudi adults originating from the Arabian Peninsula. Methods The study group consisted of 168 healthy, esthetically pleasing Saudi Arabian dental students originating from the Arabian Peninsula (93 males and 75 females, age 20–24 years). Using a caliper, three neoclassical facial canons were measured; the vertical thirds of the face, the orbital canon (intercanthal distance?=?eye fissure length), and the orbito-nasal canon (intercanthal distance?=?nasal width) and analyzed using Student’s t-test, general linear modeling, and pairwise comparison of means. Results The upper, middle, and lower thirds were not equal in measurement to each other (p?
