Jawline Rating
Your jawline is defined by three metrics: gonial angle, jaw-to-cheekbone ratio, and FWHR. AI measures all three from a single photo.
Ideal gonial angle: ~128°. Measured via 468 facial landmarks. On-device.
3 Jawline Metrics
Gonial Angle
Ideal: ~128°The angle formed at the jaw corner (gonion) between the mandibular ramus and body. A more acute angle creates a sharper jaw. This metric carries 8% weight for men and 4% for women.
Jaw-to-Cheekbone Ratio (Bigonial-Bizygomatic)
Ideal: 0.78The ratio of jaw width to cheekbone width. Creates the V-taper or facial taper that defines model-tier bone structure. Too low = narrow jaw. Too high = blocky face.
FWHR (Face Width-to-Height Ratio)
Ideal: 1.90Width of face divided by upper face height. Associated with perceived dominance and masculinity in research. Higher FWHR creates a wider, more imposing facial structure.
How to Improve Your Jawline
Body fat reduction. The #1 factor. Below 15% body fat for men reveals mandibular definition that was always there. Diet and cardio, not jaw exercises.
Posture. Forward head posture pushes the jaw back and weakens the gonial angle visually. Proper cervical alignment brings the jaw forward.
Mewing (tongue posture). Controversial, but maintaining proper tongue posture on the palate may support jaw positioning over time. Evidence is limited to anecdotal reports.
Grooming. Strategic facial hair can create the illusion of a sharper gonial angle. A lined-up beard following the natural jaw contour enhances definition.
Jawline Archetypes
Strong jaw metrics are the defining feature of several MogScore archetypes:
Chad
Dominant jawline + high FWHR + strong bone structure
Think: Henry Cavill, Chris Hemsworth
Warrior
Strong brow + wide face + defined jaw
Think: Tom Hardy, Michael B. Jordan
Masc
Very high FWHR + wide jaw + heavy bone structure
Think: Jason Statham, Dwayne Johnson
FAQ
What is the ideal gonial angle?
Approximately 128°. More acute (sharper) angles create a more defined jawline. Angles above 140° appear softer.
Can I improve my jawline?
Yes. Body fat reduction is the most effective method. Below 15% BF for men dramatically reveals jaw structure. Posture and grooming also help.
What is FWHR?
Face Width-to-Height Ratio. Measures facial width relative to midface height. Higher FWHR is associated with dominance and masculinity. Ideal is ~1.9.
