7 Craniofacial Bone Shapes & Geometric Classification Rules
Instead of tape-measure guesswork, our 3D de-rotated solver classifies your skeletal silhouette from Facial Height-to-Width Phi, Bigonial-to-Zygomatic Taper, Gonial Contour, and Vertical Thirds:
| Detected Face Shape | Height ÷ Width (Phi) | Jaw ÷ Cheekbone Taper | Best Frame & Haircut Counterbalance |
|---|---|---|---|
| Balanced Oval | 1.46 – 1.65 φ | 76% – 81% Taper | Universally versatile; Geometric/Wayfarer frames & off-forehead layers. |
| Classic Diamond-Oval | 1.48 – 1.66 φ | < 79.5% + High Midface | Cheekbone-dominant; Wayfarer/Browline rims & ear-level scissor volume. |
| Chiseled Angular (Square) | 1.42 – 1.62 φ | ≥ 81.5% (≤ 121.5° Jaw) | Strong bigonial corners; Browline/Round frames & textured top lift. |
| Tapered Heart-Diamond | 1.45 – 1.64 φ | < 77.5% + Upper Third | Broader forehead tapering to dainty chin; Round frames & chin-length layers. |
| Sculpted Oblong | ≥ 1.67 φ | 74% – 83% Taper | Elongated vertical axis; Aviator deep-lens frames & curtain/French crop fringe. |
| Soft Round-Oval | ≤ 1.44 φ | ≥ 79% Curved Jaw | Compact vertical length; Angular Geometric frames & +30mm crown lift. |

Why 3D Pose De-Rotation Beats Mirror Tracing for Face Shape Detection
Methodology
Why 3D Pose De-Rotation Beats Mirror Tracing for Face Shape Detection
Tracing your face on a bathroom mirror or taking a close 24mm selfie distorts bizygomatic cheekbone width relative to jaw width—making Oval and Diamond faces misread as Oblong or Narrow. Our engine first solves head yaw, roll, and Frankfort pitch in 3D space (plus optional 85mm Studio Lens Simulation) before measuring your true skeletal ratios.
Every scan also detects your pixel-locked trichion hairline via multi-ray CIE ΔE + vertical Sobel edge gradients, ensuring high or compact foreheads are factored accurately into your shape readout.
Bonus: CIE L*a*b* 12-Season Personal Color Analysis Built In
Knowing your bone shape solves silhouette; knowing your undertone solves wardrobe, hair dye, and frame metal. Our photometric engine samples malar cheek skin in perceptual CIE L*a*b* space (lightness L*, red-green a*, yellow-blue b*) alongside eyebrow/lip ΔE contrast to map you into the 12-Season Color System (e.g., Deep Winter, Soft Summer, Warm Autumn, Bright Spring).

Protocol
Height-to-Width Phi, Jaw Taper & CIE L*a*b* 12-Season Colorimetry
“Perceptual CIE L*a*b* colorimetry separates skin luminance (L*) from yellow-blue/red-green chromaticity (b*/a*), providing objective undertone and Individual Typology Angle assessment across all skin tones.”
How to Capture Clean Daylight Input for Bone + Color Accuracy
Combine accurate skeletal landmarks with true CIELAB colorimetry by following three studio habits:
1. Face Indirect Window Daylight
Avoid warm yellow tungsten bulbs or neon RGB monitors, which skew cheek b* warmth. Indirect natural daylight gives the purest 12-Season undertone readout.
2. Pull Bangs Briefly Off Forehead (Optional)
If you want your structural trichion bone shape rather than styled-fringe height, sweep heavy bangs slightly aside—or scan both ways to see how bangs rebalance your Phi!
3. Match Frame Metal to Your Season
Cool/Winter & Summer seasons glow in brushed silver, titanium, crystal, or black acetate; Warm/Spring & Autumn seasons shine in champagne gold, tortoiseshell, and warm bronze.

Answers
Frequently Asked Questions
What are the 7 face shapes detected by FaceRatingScore?
Our biometric classifier distinguishes Balanced Oval, Classic Diamond-Oval, Chiseled Angular (Square), Tapered Heart-Diamond, Sculpted Oblong, Soft Round-Oval, and Structured Trapezoid.
How does the 12-Season Personal Color test work?
We convert malar cheek, forehead, brow, and lip pixel patches into perceptual CIE L*a*b* coordinates—evaluating warm vs cool b*/a* balance, L* value depth, and ΔE feature contrast to assign your exact 12-season palette and 6 wearable Hex swatches.
Can losing weight or changing haircuts change my face shape?
Your underlying zygomatic and mandibular bone ratio stays stable in adulthood, while soft-tissue leanness sharpens gonial contour and strategic haircuts/frames visually shift perceived height-to-width Phi by up to 0.12.
Is my selfie uploaded anywhere for color or face shape scanning?
Zero bytes are uploaded. Both 478-point 3D mesh inference and CIE L*a*b* pixel sampling run 100% locally in your browser.
Which face shape is considered most versatile?
Balanced Oval and Classic Diamond-Oval require the least optical counterbalancing, while Chiseled Angular and Heart-Diamond photograph with striking editorial definition.
