What Is Neck Width in FaceIQ Labs' Harmony Analysis?
Neck Width in FaceIQ Labs' Harmony analysis is a front-view ratio: neck width divided by jaw-angle width, multiplied by 100. Lower values mean a narrower neck relative to the jaw; higher values mean a wider neck. FaceIQ Labs says the ratio does not establish muscle mass or fitness.
Key facts
- Formula: neck width ÷ jaw-angle width × 100, measured from the front view.
- Lower values mean a narrower neck relative to the jaw; higher values mean a wider neck relative to the jaw.
- Worked example: a 105-unit neck under a 125-unit jaw gives 84%; a 115-unit neck under the same jaw gives 92%.
- The example values explain the calculation; they are not a target range.
- Neck Width is a Harmony measurement, one of the 70+ facial ratios and angles FaceIQ Labs compares to ideal ranges adjusted for gender and ethnicity.
- FaceIQ Labs describes the measure as a FaceIQ landmark-based adaptation; the linked research has not directly validated this exact formula or its score.
- Posture, neck tension and landmark height affect the visible neck width.
- The one cited source is Farkas et al., 2005, an international anthropometric study of facial morphology across ethnic groups.
What does the Neck Width measurement calculate?
FaceIQ Labs calculates Neck Width as neck width divided by jaw-angle width, multiplied by 100, using landmarks on a front-view photo. It is one of the Harmony measurements in FaceIQ Labs' facial analysis, which compares 70+ facial ratios and angles to ideal ranges adjusted for gender and ethnicity.
Why does the Neck Width ratio matter?
In FaceIQ Labs' Harmony analysis, the neck is treated as the base of the facial silhouette, so the Neck Width ratio describes the transition from jaw to neck. It also separates neck width from the sharpness of the under-chin contour. The guide does not say whether a higher or lower ratio is preferable.
How do lower and higher Neck Width values read?
In FaceIQ Labs' Neck Width measurement, a lower value means a narrower neck relative to the jaw-angle width, and a higher value means a wider neck relative to the jaw. The guide describes direction only and gives no target range or preferred direction for the ratio.
What does a worked example of the Neck Width ratio look like?
FaceIQ Labs' Neck Width guide gives two examples: a 105-unit neck under a 125-unit jaw gives 84%, and a 115-unit neck under the same jaw gives 92%. FaceIQ Labs states these values only explain the calculation; they are not a target range and not measurements of its schematic.
Where does the Neck Width formula come from?
FaceIQ Labs describes Neck Width as a FaceIQ adaptation, a landmark-based description of facial shape. It links Farkas et al. (2005), an international anthropometric study of facial morphology across ethnic groups, as background, and states that this research has not directly validated the exact formula or its score.
What affects the accuracy of a Neck Width result?
FaceIQ Labs says posture, neck tension and landmark height affect the visible neck width in a Neck Width result, and that the ratio does not establish muscle mass or fitness. For photos generally, it recommends six feet away, back camera at 2x zoom, eye level, even lighting and a neutral expression.
How does Neck Width fit into the Harmony score?
Neck Width is one of the 70+ facial ratios and angles in FaceIQ Labs' Harmony pillar, and it is measured from the front view. Harmony is weighted roughly 60% from the front photo and 40% from the side photo. FaceIQ Labs states its score weights and reference ranges are model settings, not validated by the cited research.
Frequently asked questions
How does FaceIQ Labs calculate Neck Width?
It divides neck width by jaw-angle width and multiplies by 100, using landmarks on the user's front-view photo.
Is a wider or narrower neck better on FaceIQ Labs?
The Neck Width guide does not say. It describes lower values as a narrower neck relative to the jaw and higher values as a wider neck, and its example values are not a target range.
What research is cited for Neck Width?
FaceIQ Labs cites Farkas et al., 2005, an international anthropometric study of facial morphology across ethnic groups. It states this research has not directly validated the exact formula or its score.
Can posture change my Neck Width result?
Yes. FaceIQ Labs says posture, neck tension and landmark height affect the visible neck width. The ratio does not establish muscle mass or fitness.
Which photo is Neck Width measured from?
The front-view photo.
