Short answer
When designing human-like faces, focus on achieving harmonious relationships between features and maintaining subtle, natural asymmetries rather than aiming for mathematical perfection.

Deviations from perfect symmetry and proportion in facial features, particularly the lower third and inter-commissural line, are perceived as unattractive, suggesting that harmonious relationships between features are more critical than absolute perfection. This human factors research insight is drawn from a 2015 study published in Medicine and Pharmacy Reports. Using Illustrated questionnaire study with 236 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing human-like faces, focus on achieving harmonious relationships between features and maintaining subtle, natural asymmetries rather than aiming for mathematical perfection.
Facial proportion and symmetry significantly impact perceived attractiveness, overriding ideal forms.

Key Findings
- 01Overdevelopment of the lower third of the face was widely considered unattractive.
- 02A perfectly symmetrical and proportionate face was deemed most attractive by only 38.9% of participants.
- 03A canting of the inter-commissural line (a measure of symmetry) was considered unattractive by 36.86%.
Application
Design takeaway
When designing human-like faces, focus on achieving harmonious relationships between features and maintaining subtle, natural asymmetries rather than aiming for mathematical perfection.
How to apply
When creating character models for games, animation, or virtual reality, use reference images that exhibit natural facial balance and consider how minor asymmetries contribute to realism and perceived attractiveness.
Project actions
- 01When designing characters, consider using reference photos of real people with pleasing facial aesthetics to understand natural proportions.
- 02Test different variations of facial features to see how subtle changes affect the overall perception of attractiveness in your designs.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses a visual method (illustrated questionnaire) to assess subjective perceptions.
- +Investigates specific, measurable facial features and their impact.
Limitations
The sample size and demographic might limit the generalizability of findings. The subjective nature of attractiveness can also be a limitation.
Reliability & validity
The study's validity is supported by the use of controlled digital manipulations and a clear assessment of specific facial features. Reliability could be enhanced by testing across a wider range of participants and potentially using more objective measures of attractiveness if available.
Think critically
How might cultural differences in beauty standards influence the perception of facial proportions and symmetry, and how could a design project account for such variations?
Design Principles
"Perceived attractiveness is driven by harmonious proportions and symmetry, with specific deviations having a greater negative impact than the absence of absolute perfection."
Understanding what constitutes facial attractiveness is crucial for designers working in fields like character design, virtual avatars, and even product design where human interaction is key. This insight can inform aesthetic choices and user experience by highlighting the importance of naturalistic proportions and balance.
What This Means for Your Design
When people look at faces, they care more about how the different parts fit together nicely and look balanced, rather than if it's perfectly symmetrical. Messing up certain parts, like the chin area or the mouth line, makes a face look less attractive.
How to use in your project

Paragraph starter
The study by Mesaroș et al. (2015) highlights that perceived facial attractiveness is significantly influenced by harmonious proportions and symmetry, with specific deviations like an overdeveloped lower third or canted inter-commissural line being perceived as unattractive. This suggests that design efforts should focus on naturalistic balance rather than absolute, potentially artificial, perfection when creating human-like forms.
