Lips & Neck
Lip Fullness & Neck Width
Overview
Lip fullness and neck characteristics are subtle but meaningful dimorphic features. Fuller lips are a feminine trait, while a wider, thicker neck is a masculine trait.
Why It Matters
Lips and neck represent soft tissue dimorphism influenced by hormones. Estrogen promotes fuller lips and softer neck contours, while testosterone promotes thinner lips and increased neck musculature. These features complement the bone structure assessments. Research shows most people worldwide prefer equal-sized upper and lower lips (1:1 ratio), though preferences vary somewhat by culture and gender (Heidekrueger et al., 2017).

Lips
Lip fullness relative to lower face height
Overview
This assessment evaluates lip fullness relative to lower face height. Fuller, more voluminous lips are a feminine trait, while thinner, less pronounced lips are masculine. The measurement that helps guide this assessment is the vertical lip thickness as a percentage of the lower face height.
What to Evaluate
Key lip features to assess:
- Lip Fullness — overall lip thickness/fullness relative to the lower face height. Fuller lips are feminine; thinner lips are masculine. Research shows fillers increase attractiveness in thin-lipped individuals but can reduce attractiveness in those with already full lips (Hernandez et al., 2023).
- Upper & Lower Lip Proportions — the combined height of upper and lower lips contributes to the overall fullness score. Studies have identified specific mathematical ratios that contribute most to perception of attractive lips (Penna et al., 2015).
- Overall Lip Volume — how prominent and voluminous the lips appear in relation to the face.

Moderate lip fullness with balanced proportions.
Tips & Warnings
Important considerations when assessing lips:
- Assess natural lip fullness in a relaxed, neutral expression
- View lips from the front and profile
- Consider both upper and lower lip together
- 01Lip fillers and cosmetic procedures significantly alter appearance
- 02Makeup (lipstick, lip liner) can change perceived lip size
- 03Dehydration and aging affect lip volume
- 04Expressions (smiling, pursing) alter lip appearance

Neck
Neck width relative to jaw width
Overview
This assessment evaluates neck thickness relative to jaw width. A wider, thicker neck is a masculine trait, while a slender, elegant neck is a feminine trait. The measurement compares neck width as a percentage of jaw width. Research suggests men with thicker necks are perceived as more dominant and better fighters, and this trait is also considered attractive by women (Caton & Lewis, 2021).
What to Evaluate
Key neck features to assess:
- Neck Width — width of the neck relative to jaw width. Wider necks (approaching or exceeding jaw width) are masculine; slender necks (well below jaw width) are feminine.
- Overall Thickness — how thick or slender the neck appears overall. Powerful, thick necks are masculine; elegant, slender necks are feminine.
- Proportions — the overall balance between neck width and jaw width creates masculine (powerful) or feminine (graceful) proportions.
Score Levels
Neck width is scored based on how well it expresses your gender-typical characteristics:
- Very High (9-10) — For males: very thick, powerful neck approaching or exceeding jaw width. For females: very slender, elegant neck well below jaw width.
- High (7-8) — For males: thick neck with good masculine definition. For females: thin neck with good feminine elegance.
- Average (5-6) — Moderate neck width with balanced proportions for your gender.
- Low (3-4) — For males: thinner neck below masculine ideals. For females: thicker neck reducing feminine appeal.
- Very Low (0-2) — Neck width strongly opposite to gender-typical characteristics.
Tips & Warnings
Important considerations when assessing neck:
- Assess the overall width relative to head/jaw size
- 01Body composition (fat vs. muscle) affects neck appearance
- 02Athletic training can increase neck musculature significantly
- 03Posture affects perceived neck thickness
- 04Clothing (collars, necklines) can obscure accurate assessment
