The concept of what constitutes an attractive face has fascinated humans for centuries. While personal preference plays a significant role, scientific research reveals common patterns rooted in biology, psychology, and evolution. Examining factors like the facial width-to-height ratio (fWHR), symmetry, and hormonal markers provides a deeper understanding of these subconscious biases.
The Science Behind Facial Width-to-Height Ratio (fWHR)
Facial width-to-height ratio (fWHR) is a metric that compares the width of the face (bizygomatic width) to its height (from the upper lip to the brow). This ratio has been a subject of interest in attractiveness research, particularly concerning men. In men, a higher fWHR has been linked to higher circulating testosterone, which in turn influences bone structure and muscle development during puberty.
Testosterone, Dominance, and Its Duality
- Higher testosterone: Elevated testosterone levels during puberty can lead to more masculine facial features, including a more prominent jaw, brow ridge, and potentially a wider face.
- Signals of dominance: In an evolutionary context, these traits may signal genetic quality and strength. As a result, research, like the 2014 study on speed-daters, has found that women rate men with broader faces as more sexually attractive for short-term relationships. This short-term appeal is theorized to be an adaptive strategy for seeking partners with "good genes".
- Perceived downsides: However, this perceived dominance comes with a trade-off. Men with higher fWHR are also sometimes perceived as more aggressive, less trustworthy, and potentially unfaithful. This makes them less desirable for long-term relationships, where traits like honesty and cooperativeness are highly valued.
Factors Beyond Face Width: Universal Aesthetics
While fWHR is one piece of the puzzle, other facial characteristics contribute significantly to a person's perceived attractiveness, often having a more consistent or universal effect.
The Universal Appeal of Averageness
One of the most robust findings in attractiveness research is the preference for "averageness," or having facial features that are close to the statistical average of the population. This isn't about being uninteresting but rather about lacking any extreme or unusual features. From an evolutionary perspective, averageness may signal genetic diversity and a lack of health-compromising genetic anomalies.
The Allure of Facial Symmetry
Facial symmetry—the degree to which the left and right sides of the face are a mirror image—is another universally valued trait. High symmetry is often subconsciously associated with good health and a stable developmental process, free from genetic mutations or environmental stressors. While many studies support a positive link between symmetry and attractiveness, some recent research suggests that when other factors like averageness are considered, symmetry's influence might be less significant than previously thought. It's worth noting that perfectly symmetrical faces can sometimes be perceived as unusual, and natural variations are common.
Contextual and Gender Differences
The perception of facial attractiveness is not static and can shift based on context and gender. This dynamic is a key aspect of how we evaluate potential mates.
Shifting Preferences in Women
Women's preferences for masculine features like wider faces are not fixed. Research shows a cyclical pattern tied to hormonal fluctuations. Around ovulation, when fertility is at its peak, women show a stronger preference for more masculine faces, possibly seeking a partner with high genetic quality. However, during other parts of their cycle and when seeking a long-term, committed relationship, women tend to favor more feminized or less dominant male faces, which are perceived as more cooperative and likely to be better parents.
Gender-Specific Preferences
- Male preference for femininity: Men generally find feminine facial features in women most attractive. This preference is often universal across cultures and suggests an association with youth and fertility.
- Universal preference for femininity: A recent study identified a cross-cultural “Gender Attractiveness Gap,” finding that both male and female raters consistently rate female faces as more attractive than male faces. The researchers suggested this was partly mediated by a preference for structural femininity, even by male and female raters evaluating same-sex faces.
First Impressions and the Attractiveness Halo
Facial features shape our first impressions in a phenomenon known as the “attractiveness halo effect,” where we attribute socially desirable traits to attractive individuals. Researchers at Columbia have explored this, revealing that we project traits like trustworthiness and kindness based on subtle facial features. A person with a wider face might be stereotyped as dominant or aggressive, even if these traits are inaccurate. Interestingly, research has found that these first impressions, while often inaccurate, can be mitigated through awareness.

Comparison Table: Factors Influencing Facial Attractiveness
| Factor | General Perception in Men | General Perception in Women |
|---|---|---|
| Facial Width | Higher fWHR linked to dominance; attractive for short-term mating but less so for long-term due to perceived aggression. | Narrower, more feminized faces are typically preferred, associated with femininity and youth. |
| Averageness | Universally appealing. Being closer to the population mean is generally considered more attractive across cultures. | Universally appealing. Associated with genetic diversity and health. |
| Symmetry | Generally associated with good health and genes, though its specific impact on attractiveness can vary based on other factors. | Often seen as attractive and a marker of health, but may be a less significant factor than averageness. |
| Sexual Dimorphism | Masculine traits (strong jaw, brow ridge) can be attractive, particularly in short-term contexts. Less masculine faces preferred for long-term relationships. | Feminine traits (full lips, smaller jaw) are highly preferred, indicating youth and fertility. |
| Hormonal Signals | High testosterone leads to masculine features, signaling dominance and strength. | High estrogen leads to feminine features, signaling fertility and youth. |
Conclusion: The Holistic View of Attractiveness
Ultimately, the question of whether a wider face is more attractive is a simplification of a much more complex process. While a wider, more masculine face in men can be attractive in certain contexts due to perceived dominance, it is not a universally preferred trait and can be viewed negatively in other scenarios. For women, a narrower, more feminine face is generally favored. The most powerful predictors of attractiveness appear to be more universal traits like averageness and, to a lesser extent, symmetry. These factors, combined with cultural norms, subjective preference, and relationship context, contribute to the multifaceted nature of facial aesthetics. Attractiveness is not solely defined by a single feature but by the intricate interplay of biological signals and psychological biases that inform our perceptions of others.
