Calibrating Biometric Coordinates...
Benchmark your facial proportions against Leonardo da Vinci's Vitruvian Phi (1.618) with interactive caliper measurements.
Keep face level and expression neutral for millimeter precision
JPG, PNG, or WEBP • Processed locally via WebAssemblyThe Golden Ratio ($\Phi = 1.618$) is nature’s mathematical blueprint for harmonic balance. In human craniofacial aesthetics, neoclassical canons divide the face into three balanced vertical thirds and five transverse fifths.
Forehead height from normal hairline to the brow ridge apex. Target proportion is 33.3% of total cranial length.
Spans brow center down to the subnasale base. Primary metric for compact midface ratio and nasal dorsal projection.
Philtrum and lips down to the chin point (menton). Sculpted through masseter muscle balance, chin projection, or beard lines.
Scores between 75% and 88% reflect strong natural harmony. Scores above 90% indicate rare mathematical adherence to classical Da Vinci ratios.
