Gonial Jaw Angle
116°Vitruvian Defined Mandibular Plane
Clinical Ideal: 110° – 125°
The angle between the ascending mandibular ramus and the horizontal mandibular body. Determines jaw sharpness and profile linearity.
Chin Projection (Rickett’s E-Line)
-1.2 mmOrthognathic (Balanced Alignment)
Clinical Ideal: -2.0 to 0.0 mm
Position of the pogonion relative to the esthetic line drawn from the nasal pronasale to the soft-tissue chin point.
Nasolabial Angle
96°Harmonious Upper Lip Incline
Clinical Ideal: 90° – 105° (M) / 95° – 110° (F)
The inclination between the columella base (subnasale) and the upper lip vermilion border. Governs lip support and nasal base harmony.
Nasal Dorsal Angle
33°Balanced Dorsal Linearity
Clinical Ideal: 30° – 36°
The angle formed between the dorsal nasal bridge slope and the vertical facial plane (glabella-pogonion).
Cervicomental Angle
112°Crisp Submental Transition
Clinical Ideal: 105° – 120°
Angle between the submental chin floor and the anterior neck. High angle indicates forward hyoid carriage or submental fullness.
Lateral Profile Optimization Protocol
- Maintain posterior tongue vacuum against the soft palate to elevate the hyoid bone and tighten the submental cervicomental angle.
- Practice daily McKenzie cervical neck retractions (chin tucks) to prevent forward head carriage from artificially steepening your gonial angle.
- Trim beard neckline precisely 1 finger-width above the thyroid cartilage (Adam's apple) to create an optical illusion of a sharper 115° mandibular edge.
Clinical Standards
Ideal Jawline & Gonial Angles by Aesthetic Archetype
The gonial angle is formed at the intersection of the posterior border of the mandibular ramus and the inferior border of the mandibular body.
Masculine Ideal (115° – 123°)
Sharper, lower-positioned angle creating a defined square ramus, projecting forward chin strength and mandibular definition.
Feminine Ideal (120° – 128°)
Gentler, curved transition that tapers toward a delicate chin apex, emphasizing heart and oval facial harmony.
Obtuse / Receded (> 130°)
Down-sloping mandibular plane often linked with mouth-breathing habits or micrognathia. Corrected with mewing posture, chin projection, and beard framing.
