Scientific Mandibular Metrics
FaceMora's Jawline Analyzer measures geometric parameters that can be reliably extracted from a front-facing image:
- Bigonial-to-Bizygomatic Ratio: The width of your jaw at the mandibular angles compared to the widest point of your cheekbones (typically 75%–88% in balanced profiles).
- Lower Facial Height Ratio: The distance between the subnasale and menton relative to total facial height.
- Bilateral Jaw Symmetry: Left-to-right mandibular alignment comparing the distance from each gonion point to the central chin point.
- Chin Contour Ratio: Width across the chin tubercles relative to bigonial span.
Measurement Honesty: 3D lateral gonial angles (profile angle in degrees) require a true profile/side photo or cephalometric scan. From a frontal portrait, bigonial width and lower-face ratios provide the accurate geometric standard. For lower-face harmony, see our Facial Proportions Calculator.
Frequently Asked Questions
It calculates bigonial width (jaw angle span), bizygomatic-to-bigonial ratio, mandibular symmetry, and lower facial third proportion.
A true 3D gonial profile angle requires a lateral profile photo. On a frontal photo, bigonial width and lower-face ratios provide the standard frontal geometric metric.
