The golden ratio has been used by Greek sculptors, Renaissance painters, and modern surgeons alike to define facial harmony. Golden Ratio Face Analyzer measures six key facial ratios including face height, eye spacing, philtrum-to-nose length, and overall width and compares each to the mathematical ideal of φ (1.618). You get an overall harmony score, a letter grade, and a full ratio-by-ratio breakdown, all generated from a single uploaded photo in seconds, with no filters.
