The FWHR Calculator provides a quick way to measure the Face Width‑Height Ratio from a single frontal image. It is designed for researchers, psychologists, and forensic analysts who need a reliable numeric value without complex software.
How It Works
The tool uses AI face detection to locate key landmarks: the widest cheekbone points and the top of the hairline to the bottom of the chin. It measures the horizontal distance between the cheekbones and the vertical distance from hairline to chin, then calculates the ratio. The result is presented as a simple decimal value.
Tips for Best Results
Use a clear, frontal portrait with good lighting. Avoid hats, sunglasses, or heavy shadows that obscure facial features. Ensure the face occupies at least 50% of the image area for accurate landmark detection.
Who Benefits
Academic researchers studying facial morphology, forensic analysts estimating age or gender, and psychology students needing quantitative facial data can use the FWHR Calculator. It saves time compared to manual measurement tools.
