The 68 facial harmony measurements
Facial harmony is measured as 68 separate ratios, angles and distances, 34 from the front view and 34 from the side. Each one has a reference ideal range, and each page below explains what the measurement is, what counts as ideal, and how the celebrity library measures against it.
Methodology
RateMyFaceAI evaluates facial proportions across 68 ratios, angles, and distances from front and side photographs. Celebrity analyses use AI-placed landmarks that we verify by hand; personal analyses start with the same automatic placement, which you can review and adjust.
Our ideal bands are derived from up-to-date attractiveness research literature. Measurements are compared with the applicable bands and combined into front, side, and overall harmony scores. These ranges are aesthetic references, not population averages or universal standards of attractiveness.
Photo angle, expression, lighting, and landmark placement can affect the result. Scores describe the photographs analyzed and their proportional balance, not a definitive rating of a person's attractiveness.
