Measure face length, forehead width, cheekbone width, and jaw width using a flexible measuring tape or ruler. Each field includes visual guidance.
Our algorithm analyzes the ratios between your measurements to determine which of 6 face shape categories best matches your proportions.

Your Face Shape
Oval
Your face has balanced proportions with gentle curves.
Proportion Alignment
0% alignment with golden ratio
This shows mathematical relationship to phi (1.618), a ratio found in nature and art. Higher percentage indicates closer alignment with this classical proportion.

Our Face Shape Calculator uses mathematical ratios to categorize facial proportions into commonly recognized shape types. These categories are based on measurement relationships between face length, forehead width, cheekbone width, and jaw width.
Scientific Limitations: Face shape categorization is a simplified framework for understanding facial structure. It does not account for three-dimensional features, bone structure depth, or soft tissue characteristics. Results are analytical approximations, not clinical assessments.
Golden Ratio Context: The golden ratio (phi: 1.618) appears in various natural patterns and has been historically associated with aesthetics. Our calculator shows proportional alignment as a mathematical reference point, not as a beauty standard or clinical metric.
The face shape calculator uses measurement ratios to categorize faces into 6 common shape types (oval, round, square, heart, diamond, oblong). Accuracy depends on precise measurements. The calculator is designed for analytical purposes, not clinical assessment. Results are approximations based on mathematical ratios.
You need 5 key measurements: face length (hairline to chin), forehead width (temple to temple), cheekbone width (widest part), jaw width (jawline angle to angle), and chin length (bottom lip to chin tip). Use a flexible measuring tape or ruler for best results.

The golden ratio (phi: 1.618) is a mathematical proportion found in nature and art. In facial analysis, it's used to compare length-to-width ratios. Our calculator shows how closely your measurements align with this ratio as a reference point, not as a beauty standard.

Oval and round face shapes are statistically more common, though all 6 face shapes (oval, round, square, heart, diamond, oblong) appear across all populations. Face shape is determined by bone structure and has no bearing on attractiveness.
Use a flexible measuring tape and a mirror. Measure face length vertically from hairline to chin, then measure forehead width, cheekbone width, and jaw width horizontally at their widest points. Our calculator provides visual guides for each measurement point.
Basic bone structure and face shape category remain stable, but soft tissue changes (fat distribution, skin elasticity) can affect appearance over time. Major shape changes are rare without significant weight fluctuation or aging.
