See your face through geometry.
Decerner measures the classical proportions of a face — symmetry, the golden ratio, facial thirds, canthal tilt and more — and turns them into a clear, 0–100 harmony score with a full breakdown.
3 free analyses · no card needed
Decerner analyzes a front-facing photo, locates hundreds of facial landmarks, and measures 14 well-known proportions from classical and neoclassical aesthetics.
Beauty is subjective and shaped by culture. Decerner does not judge your worth — it measures how closely your facial geometry matches proportions studied for centuries.
Landmarks are mirrored across the vertical midline to measure how evenly the left and right halves of the face align.
The golden ratio (φ ≈ 1.618), facial thirds, the five-eye rule and other neoclassical canons are measured against their ideal values.
No black box. Every coefficient shows the exact formula and the value measured on your face.
Upload one photo and get your harmony score, a breakdown of all 14 coefficients, and a radar profile of your face.
OpenPut two faces side by side and compare their proportions and scores coefficient by coefficient.
