The masculine markers in the 17-metric scan
Each reading is shown against a reference range. Features that need a side-profile photo are listed under the table.
| Metric | What it measures |
|---|---|
| 01Facial Width-to-Height Ratio (FWHR) | Cheekbone width over upper-face height (brow midpoint to upper lip). Higher FWHR is linked to perceived dominance; male ideal band 1.85–2.1. |
| 02Jaw Taper (V-Shape) | Jaw width relative to cheekbone width. Male ideal band 0.72–0.85: a moderate taper with a strong jaw. |
| 03Chin Proportion | Chin height as a share of the lower face, from a front photo. Male ideal band 32–42%, a taller, stronger chin. |
| 04Brow-Eye Proximity | The vertical gap between brow line and eye line, as a fraction of face height. A closer brow makes the ridge look more prominent; male ideal band 0.03–0.07. |
| 05Brow Arch | Curvature of the brow line. Flatter, lower brows read masculine; male ideal band 0.15–0.28. |
| 06Canthal Tilt | The angle from inner to outer eye corner, in degrees. Masculine-neutral, but positive tilt gives the hunter-eye look; the ideal band is 4–7°. |
| 07Eye Shape (Hunter Eye Index) | Eye width-to-height ratio. Narrower “hunter” eyes score higher; it shifts with how open your eyes are, so use a relaxed face. |
| 08Midface Ratio | Eye line to mouth, over brow to chin. Ideal band 0.42–0.48; above it, the midface reads long. |
| 09Facial Thirds Balance | Middle third (brow to nose base) against lower third (nose base to chin). A longer lower third puts more of the face in the jaw. |
| 10Facial Symmetry | Left-right balance across mirrored landmark pairs. Not measured when the head is turned or tilted. |
Not measured from a front photo, because each needs a side-profile view: brow ridge projection, chin projection, nasal dorsum shape, forehead slope and the jaw (gonial) angle. The scan does not do dedicated profile scoring, so these are not in your result.
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.
| Timeframe | Lever · what moves · what does not |
|---|---|
| 1–2 weeks | 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. Metrics affected: Eye Shape (Hunter Eye Index), Brow-Eye Proximity, Facial Symmetry (apparent only: each moves with expression and head pose). |
| 4–8 weeks | 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). Metrics affected: Jaw Taper (V-Shape) (apparent only: masseter fullness at the jaw corners). |
| 8–16 weeks | 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. Metrics affected: Jaw Taper (V-Shape), FWHR (apparent — face height shrinks slightly), Midface Ratio (apparent). |
| 12+ weeks (sustained) | 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. Metrics affected: None directly: the neck and shoulders are outside the scan, but they frame the face in photos and shift the overall masculine read. |
| Surgery only | 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. Metrics affected: Chin Proportion, Nose Proportion, FWHR, Jaw Taper (V-Shape), plus side-profile features the front scan does not measure. Honestly: there is no non-surgical lever for these. |
How the 68-point scan measures masculinity
Every metric starts from a 68-point facial-landmark detection (iBUG 300-W scheme) — 17 points tracing the jawline from ear to ear, plus the brows, the nose bridge and base, six points per eye, and the lips.
On desktop the detection runs entirely in your browser; on mobile the photo is processed in memory by our scan server and deleted immediately after the landmarks are measured. Either way nothing is kept unless you choose to save it.
Gender-differentiated bands feed the scoring. Brow-eye proximity — the vertical gap between the brow line and the eye line as a fraction of face height — earns full credit at 0.03–0.07 for men, because a closer brow makes the ridge look more prominent. Brow arch flatness is scored on a curvature ratio with 0.15–0.28 as the male full-credit band.
FWHR — face width at the outer cheek landmarks divided by the height from the brow midpoint to the top of the upper lip — is credited at 1.85–2.1.
The jawline angle is measured as a front-view slope but not scored: the true jaw (gonial) angle is a side-profile measurement, taken clinically on cephalometric X-rays (average 135°, most adults 128–142°, per Proffit 2018), and a front photo cannot read it. Jaw taper, the jaw-to-cheekbone width ratio, is credited at 0.72–0.85, and chin proportion at 32–42% of lower-face height.
The same jaw geometry is isolated on the jawline angle test, the width-and-taper ratios also drive the face shape test, and lower-third dominance is measured directly on the facial thirds test.
What our data shows
Our scanner has processed 35,000+ faces. The reference bands come from published literature; each metric score places your measurement against the first scans of about 2,100 RealSmile users, so 50 is the median scanner.
In one published sample the mean FWHR was 1.86 for men and 1.80 for women, and in men a wider ratio predicted aggressive behaviour (Carré & McCormick, 2008); across studies, observers judge wider faces as more dominant and more threatening (Geniole et al., 2015).
Which canthal tilt reads as attractive differs by ethnic group: attractive Caucasian and African composite faces had a steeper eye slant than their group's average face, and attractive Asian faces a less steep one (Rhee, Woo & Kwon, 2012). Tilt itself is masculine-neutral.

Masculinity Test — FAQ
What is a masculinity test?
A masculinity test measures how masculine your facial bone structure reads — using objective metrics like FWHR, jaw taper, brow position, canthal tilt, and midface proportion. RealSmile measures 17 facial-geometry metrics from one photo (a front photo typically supports 15); side-profile features such as brow ridge projection and chin projection are not scored.
How does the AI measure masculinity?
We detect 68+ facial landmarks with TensorFlow.js, calculate proportional ratios (FWHR, jaw taper, canthal tilt degrees), and benchmark them against a calibrated dataset. The free scan gives your Face Score (a validated percentile) and your strongest metric; the full report shows each reading your photo supports.
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 — works in any browser. (3) No subscription, no invite-3-friends dark pattern. You pay once and own the report.
Is my photo uploaded anywhere?
On desktop, no — analysis runs in your browser via TensorFlow.js. On mobile, the photo goes to our scan server, is processed in memory and deleted immediately after the landmarks are measured — never written to disk. Nothing is kept unless you choose to save it.
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 facial features are considered masculine?
In published sex-dimorphism research (Perrett et al., 1998), the features that most reliably separate male-typical from female-typical faces are a prominent brow ridge sitting close to the eyes, a wider and more angular jaw, a higher facial width-to-height ratio, a forward-projected chin, and a straighter nasal bridge.
Perceived masculinity tracks the combination rather than any single feature. A front photo shows the width, jaw and brow-position parts (FWHR, jaw taper, brow-eye proximity, chin proportion), and the scan scores each separately; brow ridge projection, chin projection and the nasal bridge need a side-profile photo.
What is a masculine FWHR?
In one published sample of undergraduates the mean facial width-to-height ratio was 1.86 for 37 men and 1.80 for 51 women, and in men a wider ratio predicted aggressive behaviour (Carré & McCormick, 2008). Across studies, observers judge faces with larger ratios as more dominant and more threatening (Geniole et al., 2015, meta-analysis).
Our scan gives full credit in the 1.85–2.1 band for male-calibrated scoring, versus 1.65–1.85 for female-calibrated scoring.
Does testosterone change your face?
Published research links androgen exposure during puberty to the development of male-typical features — brow ridge prominence, jaw width, and chin projection (Perrett et al., 1998). That is a developmental association, not an adult lever: once growth is complete the facial skeleton is set, and no supplement or training protocol has been shown to reshape it.
Adult changes in perceived masculinity come from soft tissue — body-fat level, masseter size, and posture — which is what the timeline above covers. None of this is medical advice.
Is brow-eye distance a masculinity marker?
Yes. A brow that sits closer to the eyes makes the supraorbital ridge look more prominent, which reads as masculine in sex-dimorphism research.
The scan measures the vertical gap between the brow line and the eye line as a fraction of face height and gives full credit in the 0.03–0.07 band for male-calibrated scoring — one of the gender-differentiated bands used in the scoring.
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; your Face Score percentile and your metric scores are each set against one pooled reference group, not split by ethnicity.
