# Nose Bridge to Nose Width

Harmony · Front view · Nose · https://www.faceiqlabs.com/support/harmony/nose-bridge-to-nose-width

Nose-base width compared with bridge width. The calculation divides the base by the bridge.

## What is measured

Calculation: Alar nose-base width ÷ nose-bridge width

## Why it matters

This describes how strongly the nose widens from bridge to base. It gives context to nasal taper that a single nose-width measurement cannot show.

- Lower: the bridge is broader relative to the base.
- Higher: the bridge is narrower relative to the base.

## Where the idea comes from

Evidence: 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.

## A worked example

A 36-unit base over an 18-unit bridge gives 2.0. A 15-unit bridge at the same base width gives 2.4.

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

## How to read your result

Bridge shadows can be mistaken for anatomical borders. The order of division is the reverse of what the report label may suggest.

## 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.

Asked 203 volunteers to rate edited nose features on one male and one female model. Supports studying angles and projection together, with limits from the sampled faces and raters.
