Method v1.1 / Reviewed 30 October 2026

Measure the geometry.
Understand the photograph.

Our face-analysis method combines visible measurements with research-informed photo interpretation. It sets out what a result means, what evidence supports it, and what must be validated before we can call a prediction human-aligned.

01 / The standard

A measured feature is evidence.
An aesthetic preference needs validation.

A face can be described precisely without assuming there is one ideal face. Our method makes three separate claims: a geometric construction can be reproduced; an AI can describe the appearance of a photograph; and a predictive model can be evaluated against a particular panel of human raters. Each claim needs its own evidence.

We do not treat symmetry, a golden-ratio fit or a community PSL label as a universal definition of beauty. Nor does learning from human ratings remove subjectivity: it learns the preferences, context and possible biases of the people and images represented in those ratings.

Our current public description is research-informed facial geometry and photo analysis. Human-aligned attractiveness prediction is a development objective. We will use “validated against human ratings” only for a named model version and evaluation that we have actually completed and published.

02 / Three evidence layers

Different outputs. Different standards.

01 / Available

Measure

Detect landmarks, check the photo, calculate the supported distances, ratios and angles, and show the construction on the image.

Output: measured geometry
02 / Available

Interpret

Use the confirmed photo and supplied measurements to describe visible relationships and propose styling or photography comparisons.

Output: six AI dimension scores + overall /100
03 / Planned validation

Predict perception

Evaluate a dedicated model against independent human ratings, calibrate its score and test whether it can estimate rater disagreement.

Output: unavailable until validated

Photo suitability comes first

Use one clearly visible face, sufficient detail and even exposure. Front-view measurements need a front-facing photograph; profile observations need the appropriate side view. Pose, expression, blur, occlusion, glare, camera distance and clipping may limit individual readings. Checks vary by tool: a successful face detection does not certify every feature as measurable.

Our existing tools use face landmarks and image-quality checks on your device. They may reject an unsuitable image or withhold an affected result. We do not claim a clinical 3D reconstruction, a dedicated detector for every possible obstruction, or a statistical reliability percentage from these checks. An optional AI interpretation can still miss a limitation.

03 / Reading a score

A scale must name what it measures.

ResultWhat it representsHow to read it
Angles, distances and ratiosCalculations from detected or user-adjusted image points.Photo geometry, with stated anchors and units. A single photo does not reveal all depth or anatomical properties.
Golden-ratio fitProximity of our three defined proportion pairs to φ = 1.618.A mathematical comparison. Neither φ nor the product’s fit formula establishes attractiveness.
SymmetryLeft/right landmark agreement around the scorer’s fitted facial axis.Image-specific balance. Natural asymmetry and photographic perspective both matter.
Face-shape matchSimilarity to authored outline prototypes.A descriptive styling aid. Match confidence is not a calibrated probability or attractiveness score.
PSL and True TierThe existing 0–8 product scale and published community tier boundaries.A community convention. Consistent boundaries do not establish a universal or human-validated beauty standard.
AI appearance ratingA model’s current subjective reading of the submitted portrait, on the tool’s stated scale.An uncalibrated photo impression. A 0–10 label or decimal is not a human percentile, measured error margin or probability.
Free general geometry scoreWeighted local reference for symmetry and proportions, out of 100.Calculated on your device. The disclosed four-component formula is separate from the AI photo assessment.
Home and general face analysisSix AI dimension scores out of 100, with observations, evidence, limitations and a comparison to try.A product reference score for the submitted photograph. The server calculates the rounded mean of six assessable AI dimension scores.

Version 1.1 preserves these existing specialist formulas and introduces a separately labeled AI reference score for single-portrait general analysis. Geometry tools keep their own definitions. Subjective products follow the evidence and interpretation rules below.

Explore the actual constructions: golden ratio, symmetry, eye-corner angle and facial ratios.

Which tools use which method?

The homepage, Full Face Report, Face Rating, AI Attractiveness, qualitative Hunter Eyes review and portrait comparison use the six-dimension assessment. Eye angles and other geometric readings keep their measured units.

PSL Scale, Camera PSL, True Adam, True Eve, golden-ratio fit, symmetry and outline classification retain their independently defined scales or constructions. The standalone hairstyle changer is a visual styling simulation, and Roast is entertainment; neither delivers a validated attractiveness evaluation. Styling recommendations within a face report follow the framing and capture dimensions.

Free / On-device geometry

Your geometry score out of 100.

The free score summarizes measured symmetry and proportions. It is calculated entirely on your device and is available on your sharing card. It describes agreement with our disclosed geometric references; the AI assessment separately considers visible presentation across six dimensions.

Geometry score = round(0.35 × symmetry + 0.25 × thirds + 0.25 × fifths + 0.15 × length / width)
ComponentWeightCalculation / reference
Symmetry35%The existing landmark symmetry result, aligned to the facial axis.
Visible thirds25%Reference shares: 18%, 41%, 41%. Component = round(clamp(100 − 1.7 × sum of absolute percentage-point differences, 0, 100)). The upper landmark is below the hairline.
Horizontal fifths25%Five reference shares of 20%. Uses the same absolute-difference formula as the visible thirds.
Visible length / width15%Reference ratio 1.38. Component = round(max(0, 100 × (1 − abs(measured ratio − 1.38) / 1.38))).

These reference values and weights are our authored product rules. Pose, perspective, expression and landmark detection can affect the result. They are not learned human-rating weights. A high geometric fit does not establish a universal beauty ranking. AI adds photo evidence for surface appearance, framing, expression and capture, alongside relationships and contours. Its six-dimension score is a separate assessment rather than a numerical correction of this index; greater accuracy against human ratings has not yet been independently established.

Scoring / Method v1.1

Six dimension scores.
One result out of 100.

The free scan computes geometric measurements on your device. Choosing an AI report adds six photo-based dimension scores and, when every dimension is assessable, an overall Get Face Report Score. This is an AI reference assessment of the photograph, using our authored rubric. It has not been calibrated to an independent human-rating panel.

  1. Measure on the device. Detect the supported landmarks and calculate the applicable ratios and angles. These readings provide evidence for the AI interpretation.
  2. Review the confirmed photo with AI. For a chosen AI report, the model receives the confirmed images, relevant measurements and report preferences. It evaluates each of the six dimensions using the criteria below.
  3. Assign six integer scores from 0 to 100. Each score needs a visible observation and evidence. Limited findings explain the uncertainty; genuinely unavailable dimensions receive no score.
  4. Calculate the total in code. Total = round((relationships + contours + surface + framing + expression + capture) / 6). All six dimensions have equal weight. The server computes this value rather than accepting a separate overall number invented by the model.
  5. Explain what the reader can test. Each dimension includes its limitation and a practical comparison. A photo change can affect the score without implying an anatomical change.
Total = round(sum of the six AI dimension scores ÷ 6)

Equal weighting is our transparent product design choice. It is not a set of coefficients learned from the cited papers or independent human ratings. If any dimension is unavailable, we withhold the total rather than insert zero or average a changing subset. A missing side photo alone does not prevent a frontal contour assessment.

The shared rating anchors

RangeAnchorMeaning
0–19Very weakVery weak visible presentation within this dimension.
20–39WeakSeveral visible factors reduce the presentation in this dimension.
40–59MixedThe image shows a mixture of supporting and distracting factors.
60–79CoherentThe visible elements work together with some room for a comparison.
80–100StrongA strong, clear and well-integrated presentation in this photograph.

These anchors describe the visible presentation within each dimension. An image that cannot be assessed is different from an assessable image with a low score. The numbers are not percentiles, probabilities or a universal ranking of people. Photographic presentation is explicitly part of the total, so different light, focus or framing can change the result.

Historical v1.0 reports retain their original observation format. Two-person comparisons do not merge two people into one total. The independent human-rating calibration and repeatability evaluation below remain planned work.

04 / The observation rubric

Six dimensions for a useful photo analysis.

For judgments without a fixed measurement definition, we organize observations into six dimensions. These are our editorial assessment categories. They are authored scoring categories for the photograph, rather than independently validated traits or learned model-attribution coefficients. Existing tool-specific category layouts may group them differently.

01

Feature relationships

Visible spacing and proportions between eyes, brows, nose, mouth and outline, using supplied measurements where available.

Scoring criterion: Rate the visible balance and integration of feature spacing in the whole photograph, without treating one ratio as ideal.

No assumption that closeness to one ratio makes a face more attractive.

02

Outline and contours

The visible cheek, jaw and chin silhouette and how it appears in the supplied views.

Scoring criterion: Rate the visible continuity and definition of the frontal outline in context; do not infer bone or profile depth.

A frontal photo cannot establish profile projection, bone structure or a 3D reconstruction.

03

Visible surface appearance

Texture, tone and contrast that can actually be seen in this photograph.

Scoring criterion: Rate visible consistency of tone, texture and contrast in this image, acknowledging light, makeup and processing; do not rate health.

Lighting, makeup, filters and compression can alter appearance. No skin-health or biological-age inference.

04

Hair and styling

How hair volume, parting, brows, facial hair and eyewear frame visible features.

Scoring criterion: Rate how the visible hair, brows, facial hair and eyewear work with the features; absence of optional styling is not a defect.

Advice is an optional styling experiment. No prediction of an anatomical change or guaranteed score improvement.

05

Expression and eye/mouth presentation

Visible eye opening, gaze direction and mouth expression in the specific frame.

Scoring criterion: Rate the visible coherence of eye and mouth presentation in this frame; do not infer emotion, personality or social traits.

No inference of personality, trustworthiness, dominance or actual emotional state.

06

Photographic presentation

Light direction, camera angle, distance, focus, framing and background distraction.

Scoring criterion: Rate usable lighting, focus, camera position, framing and background distraction; this is explicitly a photograph dimension.

Describe the image conditions separately from the face. A poor photograph is not a low-quality face.

The current product total uses the disclosed equal-weight mean. A future human-rating predictor would need separate training and calibration against a disclosed target panel. Our current report identifies what works and what can be compared without treating distinctive features as defects.

05 / Evidence and explanations

Observation → evidence → limitation → comparison.

A useful explanation connects a claim to something the reader can inspect. Measured claims refer to supplied anchors and calculations. Photo observations identify the visible feature or condition. Advice proposes a reversible experiment, with a way to decide whether it helps.

Illustrative report wording / No invented score

“The hair is widest beside your cheeks in this photo. Compare it with the sides tucked back while keeping the parting and lighting the same. Look at whether you prefer the clearer outline; keep the option that feels more like you.”

This is an observation and styling comparison. It does not claim that hair caused a particular attractiveness score, or that a new style will change your anatomy.

Reports distinguish measured findings, visual observations and advice. Missing evidence should produce a limited or unavailable finding. A frontal photograph cannot support an invented nose-projection angle; a lighting shadow cannot establish skin health.

Attention maps indicate where a particular model attends. Component decomposition describes how a particular prediction is assembled. Neither, by itself, establishes why people find a face appealing. Our current VLM narrative is not a computed component-attribution map.

Two separate concepts must also stay separate: human disagreement is variation between raters; model uncertainty is uncertainty or error in the prediction. We currently publish neither a predicted human-rating distribution nor a calibrated uncertainty interval for an individual photo.

06 / Human-rating validation

What must happen before a stronger claim.

The following is our proposed validation protocol, not a completed study or an accuracy announcement. We plan to compare the existing geometric baseline, an off-the-shelf VLM baseline and a dedicated attractiveness predictor such as FPEM, where permissions allow.

  1. Define the task and permissions. Evaluate perceived attractiveness of an adult’s photograph under a stated rating question. Obtain appropriate consent and commercial rights for photos, annotations, model weights and training data. A citation or repository code license is not a substitute.
  2. Build independent data. An initial planning target is 500 consenting adult participants, two photos each and at least 20 independent ratings per photo. These are recruitment targets, not achieved sample counts or a power justification. Final size must reflect the measured variability and planned subgroup comparisons.
  3. Prevent leakage. Keep all photos of one person in the same partition. A proposed 60/20/20 identity split separates model development, calibration and final testing; check external model training overlap where possible. Lock the final test set, prompts, versions and selection rules before comparing candidates.
  4. Keep the human ratings independent. Randomize presentation, use the same anchored rating question, hide model outputs, include quality checks and report rater composition and agreement. Human panel averages describe that panel, not universal human preference.
  5. Report complementary metrics. Publish Pearson and Spearman correlation for agreement and ranking, MAE/RMSE and calibration plots for score error, and identity-level bootstrap intervals. Compare against baselines and rater agreement rather than advertising one large correlation as “accuracy”.
  6. Test disagreement separately. If training a distribution head, compare its predicted spread with actual individual ratings and evaluate proper distribution scores such as negative log-likelihood or CRPS. A spread estimate is not an error bar for the predicted mean. Any error interval needs its own coverage test.
  7. Check stability and generalization. Measure same-input repeatability and same-person variation across photos; examine controlled pose, distance, expression and light changes. Investigate errors across consented, self-reported evaluation groups with adequate sample sizes; do not infer protected traits from faces to create those groups.
  8. Publish before making the claim. Report sample sizes, exclusions, dataset rights, protocol, model/checkpoint and prompt versions, preprocessing, calibration, errors and limitations. A new model version needs reevaluation. We have not yet set empirically justified numeric release thresholds or completed this evaluation.

A human-rating predictor, a “human consensus” indicator, a population percentile and a numerical contribution chart remain unavailable until their respective evidence exists. Production release also requires a separate check of cost, reliability, privacy and suitability for the users the model will actually serve.

H-ARN reports a Pearson correlation of 0.9333 with average ratings on SCUT-FBP5500 and 0.838 agreement with rater-disagreement statistics. DisFace3DNet reports 0.8904 ± 0.0063 across five folds. These are different evaluation results, not interchangeable accuracy percentages or our product’s performance. H-ARN’s text also varies between variance and standard deviation terminology; any reproduction must establish the exact target and computation.

Research photo datasets may have research-only terms or additional restrictions. Our plan does not assume commercial permission for SCUT-FBP5500, MEBeauty, LiveBeauty or a downloaded checkpoint. We will verify the applicable terms and portrait permissions before any use.

08 / Limits and version history

A useful result has a clear boundary.

This service does not identify people or determine their health, personality, intelligence, trustworthiness, ethnicity, gender, hormones or precise age. Styling images are generated concepts, not evidence of future physical change. Medical and irreversible treatment decisions are outside this method.

Current free geometric scans remain on-device. Choosing a paid AI report sends the confirmed photos for processing under our privacy policy. The research plan does not authorize collecting training photos or human ratings from ordinary scans, and does not introduce a new data-retention policy.

Version 1.1 · 30 October 2026

Published the evidence layers, six-dimension observation rubric, score interpretation, research adoption status and proposed validation protocol. Integrated the interpretation rules into new AI report generation. PSL, True Tier, golden-ratio, symmetry and shape formulas remain unchanged; new single-portrait general reports now include six AI reference scores and their rounded equal-weight total out of 100; historical reports are not retroactively revalidated. Dedicated FBP models and human-rating calibration have not been deployed.
