Five-stage cephalometric pipeline — from landmark detection to percentile-ranked jawline score
Upload a side-profile photo with neutral head posture. AI identifies the Gonion (jaw corner angle), Menton (chin base), Pogonion (chin tip projection), and the Frankfort Horizontal Plane for precise anthropometric reference.
The AI calculates the angle between your mandibular ramus (vertical jaw branch) and mandibular body (horizontal jawline). The male ideal sits between 120°–130° — sharper angles signal higher testosterone exposure during development.
Analysis of jawline steepness relative to your neck angle. A flatter mandibular plane creates a more horizontal, 'square' jaw appearance. Downward slopes indicate vertical growth patterns that may benefit from orthodontic or postural intervention.
Ricketts' Aesthetic Line runs from nose tip to chin tip. AI measures your lower lip and chin position relative to this reference plane. Ideal male projection: lower lip 2mm behind E-line, chin at or slightly behind the line.
Weighted algorithm combines gonial angle (35%), chin projection (25%), mandibular definition (20%), submental-neck angle (15%), and bilateral symmetry (5%) into your final 0–100 Jawline Score with percentile ranking.
Six distinct archetypes — from elite Hunter to improvable Soft — find where your cephalometric profile lands
Angular · Sharp · Elite Mogger
Characterized by a gonial angle between 120°–125°, prominent masseter insertion, and a chin that projects to or beyond the E-line reference. The ramus is long and vertical, creating that coveted 'square' rear jaw contour. This is the genetic lottery archetype — the jaw that launched a thousand looksmaxxing forums.

Square · Wide · Dominant
Defined by significant bi-gonial width — the distance between left and right Gonion points — creating a wide, powerful lower face. The gonial angle may be slightly higher (125°–135°) but masseter development compensates with visual mass. Common in athletes and those with a history of heavy chewing or bruxism.

Lean · Defined · Photogenic
High contrast between jawline and neck due to minimal submental fat and a well-positioned hyoid bone. The mandibular definition is visible from frontal and profile views, but bone structure may be average — leanness does the heavy lifting. Submental-cervical angle exceeds 110°, creating sharp neck separation.

Weak Chin · Behind E-Line
Chin projection falls significantly behind the E-line (nose-tip-to-chin plane), often with lower lip positioned ahead of the chin. The mentolabial fold may be deep, and the lower third appears vertically compressed. This pattern has both genetic and environmental (mouth breathing, poor tongue posture) origins. Hard-maxxing interventions show highest ROI here.

High Body Fat · Hidden Structure
Underlying bone structure may be normal or even strong, but submental adiposity and cervicomental angle blunting mask the jaw's definition. The gonial angle and E-line may be favorable, but soft tissue obscures them. This is the most improvable archetype — body fat reduction alone can shift scores by 15–25 points.

Smooth Transition · Low Angularity
A gradual, curved transition from chin to ear without a visible Gonion 'corner.' The mandibular plane slopes gently, and the ramus-to-body angle exceeds 135°. Common in oval and round face shapes. Soft-maxxing through beard contouring and masseter training can create angularity that bone structure lacks.

How the Frankfort Plane and E-Line dictate your facial harmony — because a strong jaw means nothing without chin projection and neck definition
A horizontal reference line running from the top of the ear canal (porion) to the bottom of the eye socket (orbitale). This is the clinical standard for orienting the head in cephalometric analysis — your side profile is always measured relative to this plane, not to gravity.
Why it matters
Without the Frankfort reference, gonial angle and E-line measurements are meaningless. A head tilted up artificially lowers the gonial angle; tilted down artificially steepens it. The AI corrects for head orientation before taking any measurement.
A reference line drawn from the tip of the nose (pronasale) to the tip of the chin (pogonion). Dr. Robert Ricketts established this as the clinical standard for assessing lower facial projection.
Why it matters
For men, the ideal relationship places the lower lip approximately 2mm behind the E-line, with the upper lip 4mm behind. Chin projection at or just behind the line signals adequate mandibular development. A chin more than 4mm behind the E-line falls into 'receded' territory.
The angle formed where the underside of the jaw meets the neck — visible in profile as the 'jaw-neck separation.' Measured between the submental plane (under chin) and the cervical plane (neck line).
Why it matters
Angles above 110° create sharp jaw-neck definition — the 'razor jaw' look. Low hyoid bone position and submental fat both reduce this angle, creating the appearance of a 'double chin' even in lean individuals. Posture and tongue position directly impact this measurement.
From an evolutionary biology perspective, a well-developed jaw functions as an honest signal of developmental stability and hormonal fitness. Gestational and pubertal testosterone exposure directly influences mandibular growth — the ramus lengthens, the chin projects forward, and the gonial angle sharpens. Simultaneously, low cortisol (stress hormone) during development prevents the vertical growth patterns associated with 'long face syndrome.' A square, forward-grown jaw signals to potential mates and rivals alike that this individual developed in a low-stress, hormonally-optimal environment. This isn't cultural conditioning — cross-cultural studies consistently find jaw prominence ranking among the top three determinants of male facial attractiveness. The jawline analyzer measures precisely these markers, giving you an objective read on what evolution has already programmed humans to notice.
The gonial angle — formed at the intersection of the ramus and mandibular body — is the single most diagnostic measurement in jaw aesthetics. The male ideal clusters around 125°, a 'Golden Ratio' position that balances forward projection (lower angle = more horizontal jaw) with facial height (too low creates a compressed lower third). At 120°, the jaw appears aggressively square — the 'Hunter' archetype. At 130°, it's still masculine but softer. Beyond 135°, the mandibular plane slopes downward, creating a 'long face' appearance that reduces perceived dominance. Female jaws average approximately 10° higher (125°–135° for attractive female profiles), reflecting different selection pressures. Your jaw score calculator weights gonial angle heavily because it's the least changeable measurement without surgical intervention — and therefore the most honest indicator of genetic quality.
Soft-maxxing — non-surgical optimization — can improve a jawline score by 15–25 points through body fat reduction (revealing underlying bone), masseter hypertrophy (widening bi-gonial width via resistance chewing), and postural correction (advancing hyoid position to sharpen the submental-cervical angle). These interventions carry zero medical risk and should be exhausted before considering hard-maxxing. Hard-maxxing options include sliding genioplasty (advancing the chin bone forward), custom jaw implants (adding width and projection), and orthognathic surgery (repositioning the entire mandible — typically for functional bite issues that also improve aesthetics). These procedures carry significant cost ($8k–$50k) and recovery burden. The jawline AI test provides an objective baseline: score soft-maxxing improvements over 6–12 months before evaluating surgical pathways.
Proper tongue posture — the full tongue pressed against the palate with lips sealed and teeth in light contact — has been associated with favorable craniofacial development in growing children (the 'orthotropic' model). In adults with fused cranial sutures, the evidence is more modest: consistent mewing may advance the maxilla by 1–3mm over years through sutural remodeling, and it reliably elevates the hyoid bone position for immediate profile improvement. However, claims that mewing alone transforms a receded chin into a 'Hunter' jawline in adults overstate the evidence. Think of mewing as supportive optimization — it maintains gains from other interventions and prevents age-related recession — rather than a standalone transformation tool. Combined with posture work, body fat management, and masseter training, it contributes meaningfully to a comprehensive jaw-maxxing protocol.
