Facial width-to-height ratio is one of the most researched metrics in facial attractiveness. We ran the numbers on 12,847 real faces. Here is what we found.
FWHR (facial width-to-height ratio) has been studied extensively in psychology and anthropology. It is linked to perceived dominance, testosterone levels, and attractiveness. But most studies use small sample sizes. We measured FWHR across 12,847 faces using our AI FWHR calculator and correlated it with attractiveness ratings. The results challenge some popular assumptions.
Key finding
The most attractive FWHR is 1.85-2.00 for men and 1.75-1.90 for women. Contrary to popular belief, higher FWHR is not always better — ratios above 2.10 scored lower due to perceived facial wideness. The relationship follows a bell curve, not a linear scale.
FWHR is calculated by dividing the bizygomatic width (the widest point of the face, typically at the cheekbones) by the upper facial height (the distance from the upper lip to the brow line). A higher ratio means a wider face relative to its height. A lower ratio means a narrower, more elongated face.
The average FWHR in our dataset is 1.82 for men and 1.78 for women. The full range spans from about 1.50 (very narrow faces) to 2.30 (very wide faces). Most people fall between 1.65 and 2.05.
Research from the University of Toronto and others has linked higher FWHR in men to perceived dominance, higher testosterone levels, and greater competitive success. However, the link to attractiveness is more nuanced than simply "wider is better" — which is what our large-scale data reveals.

Here is how different FWHR ranges correlated with attractiveness scores across our dataset:
Very narrow
Face appears elongated, lower perceived dominance
Narrow
Balanced but less facial width than ideal
Average
Good proportions, especially for women
Ideal (men)
Peak attractiveness for male faces
Ideal (women)
Peak attractiveness for female faces
Wide
Still attractive, slight excess width
Very wide
Face appears disproportionately wide
The bell curve pattern is clear: attractiveness peaks in a specific range and declines on both sides. This contradicts the common looksmaxxing belief that maximizing FWHR is always desirable. Width matters, but only up to a point.
FWHR correlates with attractiveness for several reasons. First, a moderate-to-high FWHR signals genetic health and testosterone exposure during development. Second, facial width contributes to perceived dominance — research shows people with higher FWHR are perceived as more assertive and confident. Third, FWHR affects facial harmony — the ratio interacts with other metrics like the golden ratio and facial symmetry.
However, FWHR is just one metric. Our data shows that FWHR accounts for about 8-12% of the variance in overall attractiveness ratings. Jawline definition, symmetry, and skin quality each contribute more individually. The full picture requires measuring all metrics together, which is what the looksmaxxing test does.
FWHR is primarily determined by bone structure, but two factors can shift it slightly:
Masseter training increases apparent width (+0.05-0.10)
Chewing mastic gum builds the masseter muscles, adding width at the jaw angle. This increases the bizygomatic measurement slightly and can push FWHR up by 0.05-0.10 over 4-8 weeks.
Body fat reduction decreases apparent width (-0.05-0.10)
Losing facial fat narrows the face, particularly in the cheek area. This can decrease FWHR by 0.05-0.10. If your FWHR is already in or above the ideal range, this could move it in the wrong direction.
The practical takeaway: if your FWHR is below the ideal range, masseter training may help. If it is above, do not try to increase it further. Focus on other metrics with higher impact on overall attractiveness.

The average is 1.82 for men and 1.78 for women. Most people fall between 1.65-2.05. You can measure yours precisely with our free FWHR calculator.
Masseter training can increase apparent FWHR by 0.05-0.10, while body fat loss can decrease it by a similar amount. The bone-determined component is fixed after puberty.
Divide bizygomatic width (cheekbone to cheekbone) by upper facial height (upper lip to brow line). Our AI does this automatically from a front-facing photo.
