## About
The Face Shape Detector estimates your face shape from a front-facing photo. A face-landmark model finds points on your face inside your browser, the tool measures the forehead, cheekbones, jaw and face length, and a simple set of ratio rules suggests oval, round, square, oblong, heart or diamond. If you prefer not to use a photo, you can type four measurements instead. The photo is not uploaded to ToolStack Hub.

## How to use
1. Choose a clear, front-facing photo with your hair off your forehead, a neutral expression and good light. The photo is read in your browser and is not uploaded.
2. The first time, the face detector downloads a few megabytes, then it finds your face and measures the forehead, cheekbones, jaw and face length.
3. Read your estimated face shape, the ratios behind it and the styling ideas. Lines are drawn on your photo so you can see what was measured.
4. No photo? Open Enter four measurements instead, measure your face in the same unit, and press Find my face shape.

## FAQ
**What face shapes does the detector recognise?** Oval, round, square, oblong (rectangle), heart and diamond, which are the six categories most commonly used in styling and eyewear guides.

**How does it detect my face shape?** A face-landmark model finds hundreds of points on your face in the browser. The tool measures the forehead, cheekbone and jaw widths and the face length, divides them by the cheekbone width and applies simple rules to choose a shape.

**Is my photo uploaded or stored?** No. The photo is processed in your browser. Only the detector library and model file are downloaded from third-party servers, and your photo never leaves your device.

**How accurate is it?** It is an estimate. The rules are simple ratios that we have not validated against a set of labelled faces, so use the result as a starting point rather than a verdict.

**Can I find my face shape without a photo?** Yes. Measure the width of your forehead, cheekbones and jaw and the length of your face in the same unit, enter them in the manual section, and the same rules give you a shape.

**How do I take a good photo for the detector?** Use even light, look straight at the camera from arm’s length, keep your hair off your forehead, relax your face and avoid tilting your head.

**Is the Face Shape Detector free?** Yes, with no sign-up or limits.
