# Brow Bossing Angle

Harmony · Side view · Upper Third · https://www.faceiqlabs.com/support/harmony/brow-bossing-angle

The angle from vertical at the nasal root to the brow prominence.

> Supporting measurement: it currently has no weight in the Harmony score and is hidden in standard results.

## What is measured

Calculation: Angle: vertical above nasion → nasion → glabella

Nasion means the nasal root, subnasale the nose base, and pogonion the most forward chin point. Frankfort refers to the direction from the ear-opening landmark to the lower orbital landmark.

## Why it matters

This describes the local brow-to-nasal-root relationship separately from the forehead’s full slope. The brow and the root jointly determine the measured prominence.

- Lower: the brow direction is closer to vertical above the nasal root.
- Higher: it diverges farther from that vertical.

## Where the idea comes from

Evidence: FaceIQ adaptation. This is a FaceIQ photographic construction. Clinical profile analysis provides context, but the cited work does not validate this exact landmark formula or its scoring range.

## A worked example

A 6-unit horizontal difference over a 20-unit vertical difference gives an angle of about 16.7°.

Example values explain the calculation. They are not a target range.

## How to read your result

This supporting measurement has no Harmony score weight and is hidden in standard results. It is a photo angle rather than a bone-thickness measurement.

## Research & further reading

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

- Farkas et al. (2005). [International anthropometric study of facial morphology in various ethnic groups/races](https://pubmed.ncbi.nlm.nih.gov/16077306/). Documents variation in facial dimensions across sampled populations. Descriptive measurements explain variation; they do not establish an attractiveness score.
