Can I measure eye spacing ratio from a selfie?

Yes. Divide the distance between your pupils by your face width at the ears, using the same image and units.

Is 0.46 the ideal ratio for everyone?

Pallett and colleagues found the highest attractiveness ratings near 0.46, the population average. That finding doesn't make it a required target for your face.

Is eye spacing ratio the same as pupil distance?

No. Pupil distance measures the gap between your pupils, while the ratio expresses that gap relative to your face width.

What goes into the calculation

The calculation uses pupil distance and face width from the same image. Interpupillary distance is the distance between your pupils. Divide that distance by your face width at the ears to get the eye-to-face-width ratio.

Keep both measurements in the same units. You can use image distances without knowing your face width in real-world units. The result describes a proportion, rather than an absolute distance.

What the established evidence supports

Pallett PM, Link S and Lee K report the finding in New 'golden' ratios for facial beauty (2010). Their result supports a relationship between this facial proportion and attractiveness ratings.

The reference value is near 0.46, rather than an exact requirement for every face. The finding doesn't turn your eye spacing measurement into a complete beauty score. Keep the measured proportion separate from the judgment you attach to it.

How to read a selfie measurement

Treat the result as a measurement of the photo you're looking at. Before comparing readings, check that each uses pupil distance and face width at the ears. A measurement using a different width doesn't follow this definition.

The common mistake is giving one reading more certainty than it deserves. If another photo produces a different result, check the image and measurement points before deciding your face has changed.

What to do with the result

Use the ratio to describe your proportions, without treating distance from 0.46 as a problem to fix. For the broader term, the eye spacing guide explains the distinction between spacing and this specific ratio.

The free face-symmetry scan reads landmark distances from one selfie and reports left-right differences and basic ratios. It names what it measured. Check those names before comparing its results with a reference from the glossary.
