What are facial thirds?
The neoclassical canon divides the face vertically into three equal sections: hairline to glabella (brow), glabella to subnasale (nose base), and subnasale to menton (chin). Perfect equality is 33.3% each; modern anthropometric studies (Farkas) show attractive faces typically stay within a few percent of that.
How this tool measures it
MediaPipe's 478-point landmarker runs in your browser; we read the forehead-top, glabella, subnasale, and menton landmarks, compute each third as a percentage of total face height, and report the largest deviation from the equal 33.3% split.
One honest caveat
MediaPipe's mesh ends at the upper forehead, not your true hairline — so the upper third uses the mesh edge as its boundary. With hair pulled back the approximation is close; with a low or covered hairline the upper third reads short. Treat the result as orientation, not gospel.
