What could an ideal unit of measurement for Human Facial Features? The Facial Features largely vary with gender, age, genetic and climate. A careful observation of human skull can give the following insights.

Even though Interocular distance is a good candidate, is there any possibility of large variation of its measurements over gender, age, genetic and climate? The interocular distance can be further break down into ‘outer canthal distance’ , ‘interpupillary distance’ and ‘inner canthal distance’

The below figure shows that, inter canthal distance is one feature which has less change over the years of age progression.

The InterPupillary Distance is one feature that has no significant difference between males and females. The average InterPupillary Distance for males and females across different ethnicity is around 64mm.
IPD = InterPupillary Distance/64 is the standard used for measuring facial features from an image at PinkMirror Facial Aesthetics Studio.
The IPD is also subjected to photographic distortions. https://www.researchgate.net/public...tography_Further_Reasons_Why_Turner_Was_Wrong. Hence the selection of photographic equipment needed to be carefully considered.

- The least changed shape in human skull is eye socket (anatomically known as ‘Orbit’).
- The least changed dimension is the interocular distance.
- Jaw is in its peak shape during the most reproductive age. This is also the most changing shape on face.
- The face-width has less variation over age, in comparison to face-height.

Abnormal Inter Canthal Distances
For a well formed facial structure, the inter canthal distance is correlated with width of eye. If there is an imbalance in inter canthal distance, it can cause ‘Telecanthus’ or ‘Orbital hypertelorism’
