Eye Area
Eyes & Eyebrow Thickness
Overview
The eye area is a subtle but important marker of sexual dimorphism. Eye shape, size, and eyebrow characteristics differ notably between males and females.
Why It Matters
Eyes are often the first feature people notice. Masculine eyes tend to be smaller, deeper-set, and more hooded, while feminine eyes are typically larger, more exposed, and rounder. The eyebrows frame this area and can dramatically shift the perceived gender expression of the face. Research shows that eyes showing more of the iris with an upward tilt are judged as more attractive and youthful in women (Prantl et al., 2019).

Eye Area
Eyes
Eye size, surface area, upturn, brow position and eye shape
Overview
Eyes are evaluated across multiple features including eye size, surface area, upturn, brow position relative to eyes, and eye shape. Masculine eyes create a "hunter eye" look with narrower, less upturned eyes and close-set brows. Feminine eyes create a "doe eye" look with larger, more upturned eyes and higher-set brows.
What to Evaluate
Key features to assess when evaluating eye dimorphism:
- Eye Size & Surface Area — larger eyes with greater surface area are feminine (doe eye); smaller eyes are masculine (hunter eye). Research finds rounder eyes and balanced iris-to-eye ratios are linked to facial beauty and likability (Mitsuhiro & Kitaoka, 2016).
- Eye Upturn — upturned eyes are feminine; less upturned or horizontal eyes are masculine (not necessarily droopy). Studies confirm upward canthal tilt is associated with attractiveness (Prantl et al., 2019).
- Brow Position Relative to Eyes — brows positioned higher from the eyes with clear separation are feminine; brows sitting closer to the eyes are masculine.
- Eye Width & Shape — wider, taller, rounder eyes are feminine; narrower eyes are masculine.
- Brow Ridge Prominence — softer brow ridge is feminine; pronounced brow ridge projection is masculine.
- Overall Appearance — a soft, open "doe eye" look is feminine; a brooding, intense "hunter eye" look is masculine.

Tips & Warnings
Important considerations when assessing eye dimorphism:
- Look at your eyes in a neutral, relaxed expression
- Use good lighting that illuminates the eye area evenly
- Assess from directly in front of the face
- 01Makeup can significantly alter eye appearance — assess natural state
- 02Fatigue, allergies, and dehydration can temporarily affect eye appearance
- 03Eyeglasses may distort apparent eye size in photos
- 04Squinting or wide-eyed expressions alter the assessment

Eyebrow Thickness
Eyebrow vertical thickness and fullness relative to eye width
Overview
Eyebrow thickness measures the vertical height of eyebrows as a percentage of eye width. This is a key dimorphism marker—thicker, fuller eyebrows enhance masculine appearance, while thinner, more refined eyebrows enhance feminine appearance. This assessment focuses on thickness and fullness, not brow shape or arch. Research confirms eyebrow thickness is one of the key features affecting masculinity and attractiveness perceptions (Mogilski & Welling, 2018).
What to Evaluate
Assess your eyebrow thickness:
- Vertical Thickness — the height of the brow from top to bottom. Thicker brows are more masculine; thinner brows are more feminine. Anatomical studies confirm male eyebrows are generally flatter, thicker, and sit lower than female brows (Goldstein & Katowitz, 2005).
- Overall Fullness — how full and bold the brow appears. Fuller brows enhance masculinity; refined, delicate brows enhance femininity.
- Bold vs. Delicate — bold, prominent brows enhance masculinity; refined, elegant brows enhance femininity.

Tips & Warnings
Important considerations when assessing eyebrow thickness:
- Keep a neutral, relaxed expression — do not raise or furrow your brows
- Ensure brows are fully visible and not covered by hair or accessories
- Assess the vertical height of the brow, not the shape or arch
- 01Raising your eyebrows will make them appear thinner
- 02Brow makeup, microblading, and tinting can mask true thickness
- 03Assess the overall brow thickness, not individual hair strands
- 04Some grooming may have altered your natural brow thickness
