What is the usual adult interpupillary distance?

It's around 60 to 66 mm in adults. That range gives context for the measurement; it doesn't set an ideal eye spacing for your face.

Can I get interpupillary distance in millimetres from a selfie?

A selfie can show the distance between your pupil centres. A millimetre estimate also needs a known scale, so check how the measurement was calibrated.

Does a larger pupil distance mean wider-looking eyes?

You need face width to judge eye spacing. The distance alone doesn't tell you how widely spaced your eyes look within your face.

Pupil distance and eye spacing answer different questions

Interpupillary distance gives you a length. Eye spacing puts that length in the context of your face width. The same pupil-to-pupil distance can represent a different proportion on a wider or narrower face.

The adult range of around 60 to 66 mm is context, not a beauty target. It doesn't tell you which distance would suit your face. A number alone leaves out the comparison that matters for judging spacing.

What a selfie can measure

A selfie can show the gap between the pupil centres. Measuring that gap in an image isn't the same as knowing its length in millimetres. Without a known scale, the photo doesn't supply that conversion.

Check the units before reading the result. A distance in pixels describes the image; a ratio describes the distance relative to another measurement. Neither becomes a millimetre value just because the output looks precise.

Keep pose and framing consistent when comparing photos. If the readings differ, check how they were measured before deciding your eye distance has changed.

How to read a scan result

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 that name before treating an output as interpupillary distance. A symmetry result and a pupil-distance measurement describe different things. Evidence for interpupillary distance as a measurement is established; that doesn't make every photo estimate equally dependable.

Use the glossary to check unfamiliar labels. Compare results only when they describe the same distance, use the same units, and have a clear measurement method.
