How Is Facial Symmetry Calculated?
Facial symmetry is measured by establishing a true vertical midline passing through the glabella (between the eyebrows) down through the subnasale (base of the nose) and the menton (tip of the chin).
Our algorithm then measures the perpendicular distance from this central axis to multiple paired anatomical landmarks on the left and right sides:
- Outer & Inner Canthi: Left vs. right eye corners.
- Zygomatic Arches: Left vs. right cheekbone apex points.
- Nasal Alar Bases: Left vs. right nostrils.
- Cheilion Points: Left vs. right oral commissures (mouth corners).
- Gonial Angles: Left vs. right mandibular jaw angles.
Natural Human Asymmetry: Virtually no human face is 100% symmetrical. Normal micro-asymmetries are a standard feature of human biology and do not detract from attractiveness. To explore vertical balance, see our Facial Proportions Calculator.
Frequently Asked Questions
Facial symmetry refers to the degree of geometric correspondence between paired anatomical landmarks on the left and right sides of your face relative to the central vertical axis.
No. Natural, minor asymmetries are universal and normal in human anatomy. Studies show slight asymmetry adds character and dynamism.
FaceMora compensates for planar roll rotation automatically. However, looking directly at the camera at eye level yields the most accurate symmetry reading.
