# Golden Ratio Face Analysis

> Golden Ratio Face Analysis is an AI-powered tool that analyzes facial proportions against the mathematical golden ratio (φ ≈ 1.618). Upload a photo to discover how your facial features align with this ancient principle of beauty and harmony used in art and architecture for centuries.

## Key Features

- **Golden Ratio Analysis**: Measure facial proportions against the mathematical constant φ (1.618)
- **Multiple Facial Measurements**: Analyze face height ratios, eye spacing, mouth proportions, and philtrum measurements
- **Composite Beauty Score**: Receive an overall harmony score indicating alignment with golden ratio principles
- **Visual Annotations**: Get annotated images showing the analyzed facial measurements and proportions
- **Educational Content**: Learn about the science and history behind golden ratio in facial beauty

## Services

- [Golden Ratio Scanner](https://www.golden-ratio-face.com): Main analysis tool - upload a frontal photo for facial proportion analysis
- [Analysis Results](https://www.golden-ratio-face.com/show_result/): Detailed breakdown of facial measurements and golden ratio alignment

## Measurements Analyzed

- **Face Height Ratio**: Upper face (forehead to nose bridge) vs lower face (nose bridge to chin)
- **Eye to Mouth Ratio**: Distance between eyes compared to mouth width
- **Philtrum to Nose Ratio**: Philtrum length relative to total nose length
- **Overall Facial Harmony**: Composite score of all measurements combined
