Midface ratio calculator
Measure midface ratio by hand or from a portrait photo. GoldenFace uses the public interpupillary-distance formula and keeps the result on this page as a portrait reference.
Use a centered, front-facing portrait with steady light. The server CPU analysis estimates visible landmarks without face identification or stored photos.

Manual calculator
Enter two measurements from the same photo or ruler. The units can be pixels, millimeters, or any consistent unit.
Formula
midface ratio = interpupillary distance / pupil-to-upper-lip distance
Use the same unit for both fields. The ratio is unit-free.
Ratio

Enter two distances
Use matching units to get an instant midface ratio.
The horizontal line marks interpupillary distance. The vertical guide runs from the pupil line to the upper lip.
Treat the result as a portrait reference. Angle, lens distance, expression, and landmark quality can change the number.
Photo calculator
GoldenFace prepares the image in the browser, sends the prepared portrait to the server CPU analyzer, and keeps the midface result on this page.
Upload a supported portrait
JPG, PNG, or WebP up to 10MB works best with a centered, front-facing face.

Upload a portrait to see the midface ratio, confidence, reliability, and photo-quality notes in this panel.
Visual guide
Use these visual examples before uploading. A clear front-facing photo helps the detector read landmarks, while angle, blur, or covered features can make the result less stable.
Recommended upload
This kind of image gives the landmark detector the best chance to compare symmetry, thirds, spacing, and ratio cues.
Avoid this upload
If key points are hidden or distorted, GoldenFace can still try, but the score and metric notes may be less reliable.

What the report highlights
Calculate interpupillary distance divided by pupil-to-upper-lip distance, then read the result with photo reliability and thirds context.
Calculate interpupillary distance divided by pupil-to-upper-lip distance, then read the result with photo reliability and thirds context.
Enter two matching-unit measurements or upload a clear, centered portrait.
For photos, the browser prepares the image and the server CPU detector estimates visible landmarks.
GoldenFace calculates interpupillary distance divided by pupil-line-to-upper-lip distance.
Read the ratio with confidence, reliability notes, and facial-thirds context.
Midface ratio is a portrait proportion reference that compares interpupillary distance with the vertical distance from the pupil line to the upper lip.
Use the same unit for both measurements, then divide interpupillary distance by the pupil-to-upper-lip distance. For example, 64 divided by 80 gives 0.80.
Yes. Lens distance, head tilt, expression, lighting, and landmark confidence can all change the apparent ratio in a photo.
No. GoldenFace presents the result as an entertainment and portrait-reference tool, not professional advice or a beauty ranking.
