Facial ratios are mathematical relationships between distances on a face. This calculator estimates 12 of them from selected MediaPipe landmarks in one front-facing photo. Some names overlap with artistic canons, psychology research, or clinical anthropometry, but published methods do not always use the same anchors. The formulas below describe exactly what this tool computes.
The comparison bands are internal calculator references selected for this landmark geometry and historical score continuity. They are not universal ideals, population norms, or treatment thresholds. Use the result to describe this photo and compare consistently taken photos, not as a beauty or health test.
Focus or hover a free ratio in your results above to isolate its photo overlay. Below is the full methodology for all 12measurements, including the calculator reference used for scoring.
Formula: cheekbone width ÷ visible upper-face height (upper-eyelid midpoint to upper lip)
Describes how broad the visible upper face appears in this photo. Published fWHR studies use more than one vertical anchor, so this calculator-specific value should only be compared with the band and method shown here.
Formula: visible face height (top mesh point to chin) ÷ cheekbone width
Describes how long the visible face mesh is relative to its width. It helps explain the geometry behind a face-shape result, but it is not the clinical facial index and does not detect the hairline.
Formula: jaw width ÷ cheekbone width
Compares lower-face width with the widest cheekbone span. Camera distance, head turn, hair, and landmark visibility can all change the photo estimate.
Formula: iris-center distance ÷ cheekbone width
Compares the detected iris-center distance with visible face width. It is a photo proportion, not a millimeter pupillary-distance measurement for glasses.
Formula: inner-eye gap ÷ average visible eye width
Shows how the gap between the eyes compares with the average width of the two visible eyes. The familiar one-eye-gap rule is an artistic convention, not a requirement.
Formula: average left/right inner-to-outer eye-corner angle against a fitted face-horizontal axis
Estimates whether the outer eye corners sit above or below the inner corners. It is reported in degrees and is especially sensitive to camera height and head pose.
Formula: brow-midpoint-to-nose-base distance ÷ visible face height
Shows how much of the detected visible face height lies between the brow midpoint and nose base. Other online midface calculators use different anchors, so their numbers are not interchangeable.
Formula: nose-base-to-chin distance ÷ visible face height
Shows how much of the visible face height lies between the nose base and chin. A difference from the calculator band is not evidence of asymmetry or a treatment need.
Formula: mouth-corner width ÷ cheekbone width
Compares detected mouth width with visible face width. Expression and lens perspective can move the estimate even when the underlying face is unchanged.
Formula: nose-ala width ÷ mouth-corner width
Compares the detected width of the nose base with mouth width. Facial proportions vary across people and populations, so the band is a calculator reference rather than a universal norm.
Formula: nose-bridge-to-tip distance ÷ visible face height
Compares the detected nose bridge-to-tip distance with visible face height. A front photo cannot provide a full three-dimensional measure of projection or profile shape.
Formula: outer lip height ÷ mouth-corner width
Compares detected outer lip height with mouth width. Keep the lips relaxed: smiling, pressing, or pursing them changes the photo measurement.
Facial width-to-height ratio (fWHR) has been studied in psychology, but it is not a single standardized beauty metric. The original Carré and McCormick method used cheekbone width and a mid-brow to upper-lip height. Later papers used other anchors, and reviews report small, inconsistent, or context-dependent associations. This tool therefore labels its eyelid-midpoint version as an fWHR-style photo measurement rather than treating it as a personality or attractiveness test.
Key fWHR facts

The midface ratio measures the vertical middle third of the face. On the most common online convention — interpupillary distance divided by the vertical distance from the pupil line to the upper lip — values cluster around 1.0, with roughly 0.9–1.1 usually described as balanced: a noticeably higher value reads as a "compact" midface, a lower one as a longer midface. This calculator uses a different, landmark-stable convention — midface height share, the brow-midpoint-to-nose-base distance divided by visible face-mesh height, with a reference band of 0.38–0.44.
The two conventions measure different landmark pairs, so their numbers are not interchangeable and neither is a universal ideal — treat any single figure as a photo-based estimate, not the clinical midface index. Upload a photo above and the calculator measures yours from 478 landmarks in your browser.
The midface ratio compares the height of your midface — the vertical span from your brow line down to the base of your nose — against the visible face-mesh height. The value describes landmark geometry in this photo; by itself it cannot diagnose aging, sex, ethnicity, skeletal structure, or a need for treatment.
Why photo setup matters
Camera height and pitch change vertical distances, while close wide-angle selfies exaggerate the center of the face. Expression and landmark visibility add more variation. Repeat photos at the same eye-level angle and distance for a useful comparison.
What the calculator measures
The numerator runs from the midpoint of the two detected brow peaks to the nose-base landmark. The denominator runs from the visible top face-mesh point to the chin. The tool divides those pixel distances, so no real-world unit or hairline detection is required.
Quick reference: this calculator's midface score
Different midface ratios pair with different face shapes — for styling implications by shape, see our face shape hairstyle guide.
The overall score is an equal-weight average of each measurement's proximity to its calculator reference band across all 12ratios. It is designed as a compact summary of this photo—not a percentile, probability, or validated attractiveness score.
85–100 — Very close reference match
Most measurements sit close to this calculator's selected reference bands.
75–84 — Close reference match
Several measurements sit close to the calculator's reference bands, with some differences.
65–74 — Mixed reference match
The result includes both closer matches and larger differences from the selected bands.
Below 65 — Larger reference difference
More measurements differ from the selected bands. This is descriptive, not a beauty, health, or clinical verdict.
Front-facing, eye-level camera
Vertical angle and head turn distort several ratios. Keep the lens at eye level, your chin neutral, and both sides of the face equally visible.
Neutral expression, lips relaxed
Smiling changes mouth width and lower-face landmarks; pressed or pursed lips change the lip ratio. Use a relaxed expression.
Keep the face outline visible
Move hair away from the cheeks and jaw so the detector can see the face contour. The tool uses a visible forehead mesh point, not the hairline.
Avoid close wide-angle selfies
Short camera distance exaggerates central features and compresses side-to-side proportions. Step back and use a modest zoom when possible.
Even, soft lighting
Heavy shadows and glare can obscure feature edges. Diffused front lighting gives the landmark model a clearer image.
There is no single 'good' fWHR. Published studies use different vertical anchors and report small, context-dependent associations rather than a beauty standard. This calculator uses a visible-mesh upper-face measure and a 1.8–2.1 internal comparison band; compare the number only with the method shown here.
There is no universal ideal because 'midface ratio' can describe different landmark pairs. This tool divides brow-midpoint-to-nose-base distance by visible face height and uses 0.38–0.44 as its calculator reference band. The popular pupil-distance-to-midface-height convention produces a different number and should not be compared directly.
It detects a brow midpoint, nose base, visible forehead-top mesh point, and chin from one front-facing photo. It divides brow-to-nose-base distance by visible mesh height. The result is a dimensionless 2D photo estimate—not a hairline measurement, sub-millimeter scan, or clinical anthropometric exam.
The distance calculations are reproducible geometry when the same landmarks and photo conditions are used. That does not make the calculator's comparison bands universal laws of attractiveness. Research reviews find substantial variation in definitions, samples, populations, and aesthetic conclusions, so use the result as a descriptive photo comparison.
Some soft-tissue proportions can change over time, while a single-photo result can also move because of expression, lens distance, lighting, pose, or landmark detection. For before-and-after comparisons, use the same neutral expression, camera, distance, and eye-level angle. This tool cannot diagnose age-related anatomical change.
They compare different distances. This tool's fWHR-style value divides cheekbone width by visible upper-face height. Golden-ratio tools compare other facial distances with phi (about 1.618). Neither number is a validated standalone measure of beauty, personality, or health.
A photo ratio is a description, not a treatment recommendation. Camera setup, expression, hair, and styling can change how proportions look without changing anatomy. If you are considering a medical or dental intervention, discuss your goals and appropriate three-dimensional measurements with a qualified clinician rather than using this result to self-diagnose.
No. The score is an equal-weight average of distance from 12 calculator reference bands. It is not validated as an attractiveness, health, ethnicity, age, or treatment score, and it cannot capture expression, three-dimensional structure, or individual character.
