| # Face Shape Measurement Reference (8 Shapes) |
|
|
| A compact, reusable reference for identifying face shape from four tape measurements: |
| **forehead width, cheekbone width, jawline width, and face length**. |
|
|
| ## Files |
|
|
| | File | What it is | |
| | --- | --- | |
| | `face_shape_measurement_sheet.csv` | One row per shape — oval, round, square, heart, diamond, oblong, triangle/pear, hourglass. The four columns state where each measurement sits *relative to the other three*; `fastest_check` gives the single quickest screening rule for that shape. | |
| | `classify_face_shape.py` | Zero-dependency Python CLI: give it your four numbers, it returns the shapes whose rules actually match, ranked, with every matched and failed condition listed. Usage: `python classify_face_shape.py --forehead 14.2 --cheekbones 15.0 --jawline 13.6 --length 19.1` | |
|
|
| ## How the rules are expressed — and why |
|
|
| The sheet is deliberately **relative, not absolute**. Published face-shape guides describe |
| shapes with language like "slightly narrower than the cheekbones" or "cheekbones clearly the |
| widest part". This sheet preserves that structure instead of inventing millimetre cutoffs that |
| no source supports. The tool's tie band for "roughly equal" is its own adjustable parameter |
| (`--tol`, default 3%) — not a figure taken from any study. |
|
|
| ## Limits, stated plainly |
|
|
| Two judgments cannot come from a tape measure: the **jaw angle** (which separates round from |
| square) and **chin shape** (which separates heart from diamond). When the four numbers cannot |
| separate two candidates, the tool reports both and flags the manual check rather than guessing. |
|
|
| ## Relationship to image datasets |
|
|
| This is a **rule/measurement reference, not an image dataset**. It is intended to complement |
| the image-based face-shape datasets on Kaggle and Hugging Face: those train classifiers to |
| output a shape label, while this sheet documents the relative-width rules that define the |
| labels themselves. |
