Ear Protrusion Angle

A front-photo angle between the outer ear and a vertical reference through each cheek.

What is measured

The calculation

Mean angle of outer-ear-to-cheek/mouth-level reference against vertical

Follow the measurement

Select a label to focus on its line. Select again to show all measurements.

Schematic illustration, not to scale. Lines show the measurement construction; this is not an ideal face or a scored result.

Why it matters

This gives a second description of the ear’s contribution to the face outline. Unlike the width percentage, its angle depends on the vertical position of the ear and mouth reference too.

  • Lower: the ear direction lies closer to the vertical reference.
  • Higher: the ear direction tilts farther away from that reference.

Where the idea comes from

FaceIQ adaptation

This is a FaceIQ landmark-based description of facial shape. The linked research provides background on facial measurement or perception; it has not directly validated this exact formula or its score. [1]

A worked example

If the two constructed ear angles are 10° and 14°, the result is their mean, 12°.

Example values explain the calculation. They are not a target range and are not measurements of the schematic above.

Research & further reading

The sources below explain the history or related evidence. FaceIQ’s score weights and reference ranges are model settings; these papers do not collectively validate the scoring system.

    Documents variation in facial dimensions across sampled populations. Descriptive measurements explain variation; they do not establish an attractiveness score.
