The 17 masculine metrics we measure
Every metric is benchmarked against a calibrated dataset and returned as a percentile rank — not a vague 1-10 score.
Jawline Sharpness
Mandibular angle + gonial definition — the single strongest masculine signal.
FWHR (Facial Width-to-Height Ratio)
Bizygomatic width over upper-face height. Higher FWHR correlates with perceived dominance.
Canthal Tilt
Positive tilt (outer corner higher than inner) reads as hunter-eye and masculine-neutral.
Brow Ridge Projection
Supraorbital bossing — the shelf over the eyes separating masculine from feminine skulls.
Midface Ratio
Compact midface (short philtrum-to-cheek) is a high-testosterone marker.
Bigonial Width
Distance between jaw angles — the "wide jaw" metric.
Bizygomatic Width
Cheekbone-to-cheekbone span relative to face height.
Mandible-to-Midface Ratio
Lower third dominance — masculine faces carry weight in the jaw.
Chin Projection
Forward chin position vs recessed — forward-projected is masculine default.
Nasal Dorsum Straightness
Straight or slightly convex bridge vs concave feminine scoop.
Supraorbital Rim Depth
Deep-set eye sockets cast shadows that read as masculine.
Neck-Jaw Definition
Visible separation between mandible and neck — low body-fat signal.
Forehead Slope
Slight backward slope is masculine; vertical forehead reads feminine.
Cheekbone Projection
Forward zygomatic projection — shared male/female high-trust signal.
Hunter Eye Ratio
Upper eyelid exposure — hooded, compressed eyes read masculine.
Facial Symmetry
Bilateral balance across all 17 landmarks.
Overall Masculinity Composite
Weighted score combining all 16 metrics into a single percentile.
How long until your masculinity score actually moves?
Bone structure doesn't change in 30 days. Soft tissue does. Here's the honest timeline for each lever, ranked by speed-to-effect.
Sleep + posture + photo conditions
Eye-area puffiness drops, brow-ridge shadow reads sharper, neck-jaw line cleans up under correct head pose.
What does NOT change: Bone, muscle mass, fat.
Brow Ridge Projection, Supraorbital Rim Depth, Hunter Eye Ratio, Neck-Jaw Definition (apparent only).
Mastic gum (masseter training) + facial-fat reduction (start of cut)
Masseter hypertrophy adds visible jaw flare; first 2-4 lbs of facial fat starts coming off.
What does NOT change: Skull shape, mandibular angle, FWHR (cheekbone width is still bone).
Jawline Sharpness, Bigonial Width (apparent), Neck-Jaw Definition.
Sustained body-fat reduction to 13–16% range
Cheekbone shadow sharpens, midface compacts visually, jaw-fat fully reveals underlying structure. This is the single biggest lever for most users.
What does NOT change: Underlying bone — but appearance can shift dramatically.
Jawline Sharpness, Cheekbone Projection (apparent), FWHR (apparent — face height shrinks slightly), Midface Ratio (apparent).
Resistance training + body recomposition
Neck thickness, trap definition, shoulder line — all of which frame the face in photos and shift overall masculine read. Slight hormonal effects from training (within normal range).
What does NOT change: Facial bone. Hairline.
Neck-Jaw Definition, overall photographic masculine read (not directly a metric but improves rating).
Genioplasty, rhinoplasty, zygoma implants, orthognathic
Actual bone position. Permanent.
What does NOT change: The fact that it's real surgery with real risk. Revisions are common. Costs $5k–$50k+. Not a routine purchase.
Chin Projection, Nasal Dorsum Straightness, Bizygomatic Width, Bigonial Width, Mandible-to-Midface Ratio. Honestly: there is no non-surgical lever for these.
If a competitor sells you a 30-day program promising jaw bone growth, FWHR change, or cheekbone projection without surgery — they're selling soft-tissue effects (fat loss, muscle tone, posture) under bone-change marketing. The soft-tissue effects are real. The bone-growth claims are not. You can score this page's 17 metrics and pick which levers actually move what you care about.

How your masculinity score is built
5 markers, 5 weights — here's what's actually moving your score
Most masculinity tests aggregate into one number. We publish the component weights so you can see exactly what drove your result.
Jawline angle (gonial)
28%
Sharp gonial angle reads strongest in dominance ratings.
FWHR (bizygomatic-to-upper-face-height)
24%
Tier-1 evidence (Geniole 2015, PMID 26181579).
Brow ridge prominence
20%
Heavy brow ridge clusters sex-typical features.
Canthal tilt (eye-corner angle)
14%
Positive tilt aligns with hunter-eye reads.
Facial thirds proportion
14%
Lower-third dominance signals jaw projection.
Research note
FWHR has the strongest peer-reviewed support (Geniole 2015 meta-analysis, PMID 26181579). Other markers have stronger community-consensus and weaker direct research — hence the lower weights.
Diagnose your weakest marker
Your full report surfaces each sub-score individually so you can see which marker is dragging the composite — and which is carrying it.

Masculinity Test — FAQ
What is a masculinity test?▾
A masculinity test measures how masculine your facial bone structure reads — using objective metrics like jawline sharpness, FWHR, brow ridge projection, canthal tilt, and midface compression. RealSmile runs 17 of these measurements from a single photo and gives you a percentile rank for each.
How does the AI measure masculinity?▾
We detect 68+ facial landmarks with TensorFlow.js, calculate proportional ratios (FWHR, mandible-to-midface, canthal tilt degrees), and benchmark them against a calibrated dataset. You get a percentile for each metric plus a composite masculinity score.
How is this different from Umax or Looksmax AI?▾
Three differences. (1) Price: $14.99 one-time vs Umax's ~$207/year annualized. (2) No app download — runs in your browser. (3) No subscription, no invite-3-friends dark pattern. You pay once and own the report.
Is my photo uploaded anywhere?▾
No. All analysis runs client-side in your browser via TensorFlow.js. Your photo never touches our servers. This is a core design choice, not a marketing line.
Can I actually improve my masculinity score?▾
Bone structure is fixed, but perceived masculinity is not. Lower body fat sharpens jawline definition, mewing and posture affect midface projection, beard shaping alters jaw perception, and angle/lighting change FWHR readings by 10-15%. The paid report includes a 7-day improvement plan tied to your specific weak metrics.
What ages is this accurate for?▾
Calibrated for ages 16-55. Under 16, facial bones are still developing so scores may understate your final structure. Over 55, skin laxity can obscure bone landmarks.
Does ethnicity affect the score?▾
The model benchmarks against a multi-ethnic dataset. Absolute measurements (FWHR, canthal tilt in degrees) are objective; percentile ranks are relative to the full dataset, not ethnicity-specific.
How much does the full report cost?▾
$14.99 for the single Full Report, or $34.99 for All-Access lifetime (every test, unlimited rescans). One-time payment, no subscription, 7-day money-back guarantee.
