Rule Of Fifths is a classic front-view facial proportion check. It divides the face width into five vertical parts using the cheek edges and eye corners, then compares how evenly those parts line up.
Balanced fifths can make the eyes, midface, and outer face width feel more harmonious in photos. It is one small measurement, best read together with symmetry, thirds, jaw, nose, and eye metrics.
The test finds six facemesh landmarks: both cheek edges, both outer eye corners, and both inner eye corners. It measures each segment as a share of total face width and reports the average deviation from an ideal 20%.
