Brow Thickness
Vertical brow thickness compared with a horizontal brow-to-outer-hood span.
What is measured
The calculation
Mean of brow peak-to-arch thickness ÷ inner-brow-to-outer-hood width × 100

Follow the measurement
Select a label to focus on its line. Select again to show all measurements.
Why it matters
It describes the visible weight of the brow above the eye. The width reference keeps the measurement relative to the local eye area rather than raw photo size.
- Lower: a thinner vertical brow relative to the reference span.
- Higher: a thicker vertical brow relative to the reference span.
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
A 6-unit thickness over a 30-unit reference width gives 20%. The app averages the left and right percentages.
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.

A contemporary assessment of facial aesthetic preferencesCompared ratings of edited brow and nose features on four female models. The authors emphasized individual facial harmony; this is context for feature relationships, not a test of every brow metric.
