What this site does
Face Ratio is a free web tool that measures your facial proportions—face length, face width, estimated face area, and their ratios—using AI-based facial landmark detection. Upload a front-facing photo and you get an instant, visual analysis you can compare against celebrity benchmarks, along with guides that turn the numbers into practical decisions: hairstyles for your face shape, skincare fundamentals, the real story behind the Golden Ratio, and current beauty trends.
No signup, no app install, no fee.
How the analyzer works
The tool uses MediaPipe Face Mesh, an open-source machine-learning model that locates hundreds of landmark points on a face, together with OpenCV.js for image processing. From those landmarks it computes distances and ratios, calibrated against average human iris size to estimate real-world measurements in centimeters.

Our point of view
Numbers are a fun and useful reference—but they're not a verdict. Research on attractiveness consistently shows that symmetry, skin quality, grooming, and expression matter far more than matching any single "ideal" ratio. Our goal is to help you understand your proportions and use styling to your advantage, while keeping perspective: as our footer says, a person's charm isn't just about their face shape.
Accuracy disclaimer
Measurements are estimates and vary with photo angle, distance, lens distortion, lighting, and hair covering the face outline. Results are provided for entertainment and general reference only, and are not medical, cosmetic, or professional advice.
