The curvature of the upper lip and the arc of the smile are key determinants of an aesthetically pleasing smile, with an upward curvature and a consonant smile arc being most frequently associated with attractiveness. This classic design research insight is drawn from a 2022 study published in Zenodo (CERN European Organization for Nuclear Research). Using Literature review with 17 studies selected from 4497 articles, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize an upward upper lip curvature and a consonant smile arc when designing elements that aim to represent or enhance a smile.

Key Findings
- 01A high or medium anterior smile line positively influences aesthetic perception.
- 02A parallel smile arc is considered aesthetically favorable.
- 03Straight or upward upper lip curvature contributes to an attractive smile.
- 04A commissural type of smile is preferred.
- 05Gingival exposure of less than 2 mm is associated with a more attractive smile.
Application
Design takeaway
Prioritize an upward upper lip curvature and a consonant smile arc when designing elements that aim to represent or enhance a smile.
How to apply
When designing characters for animation, video games, or virtual reality, ensure their smiles adhere to these established aesthetic principles for greater user acceptance.
Project actions
- 01When evaluating existing designs, consider how well they incorporate principles of smile aesthetics.
- 02If your design involves facial features, research specific aesthetic guidelines relevant to your target audience.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Systematic literature review methodology.
- +Focus on a specific, measurable aesthetic outcome (smile aesthetics).
Limitations
The findings are primarily based on dental aesthetics and may not directly translate to all design contexts.
Reliability & validity
The reliability of the findings is supported by the systematic review of multiple studies. Validity is established by focusing on quantifiable aesthetic parameters within the domain of dental aesthetics.
Think critically
How might cultural differences influence the perception of an 'aesthetically pleasing' smile, and how could a design project account for such variations?
Design Principles
"Symmetry and harmonious curvature are foundational to aesthetic appeal."
Understanding these classic aesthetic principles allows designers to create products and experiences that align with widely accepted notions of beauty and harmony. This is crucial in fields ranging from cosmetic dentistry and facial prosthetics to character design in animation and virtual reality.
What This Means for Your Design
For a smile to look good, the top lip should curve upwards and follow a smooth, consistent arc, with not too much gum showing.
How to use in your project
- 1.Reference this research when discussing the aesthetic considerations of your design, particularly if it involves facial features or aims for a universally pleasing appearance.

Paragraph starter
Research into smile aesthetics indicates that specific lip positions and curvatures significantly contribute to perceived attractiveness. An upward upper lip curvature and a consonant smile arc, alongside minimal gingival display (less than 2 mm), are frequently cited as indicators of a pleasing smile. These findings, derived from a review of academic publications, highlight classic principles of facial harmony that can inform design decisions in various fields.
