What Is Brow Thickness in FaceIQ Labs' Harmony Analysis?
Brow Thickness is a supporting front-view Harmony measurement at FaceIQ Labs. It expresses vertical brow peak-to-arch thickness as a percentage of the horizontal inner-brow-to-outer-hood width. It currently has no weight in the Harmony score and is hidden in standard results.
Key facts
- Brow Thickness is a Harmony measurement in the front-view eye region.
- Calculation: mean of brow peak-to-arch thickness ÷ inner-brow-to-outer-hood width × 100.
- It is a supporting measurement with no weight in the Harmony score.
- It is hidden in standard results.
- The app averages the left and right percentages.
- It does not measure hair density or eyebrow health.
- It is a FaceIQ landmark-based adaptation; the linked research has not directly validated this exact formula or its score.
- Cited background research: Biller & Kim (2009), 'A contemporary assessment of facial aesthetic preferences'.
How does FaceIQ Labs calculate Brow Thickness?
FaceIQ Labs calculates Brow Thickness as the mean of brow peak-to-arch thickness divided by the inner-brow-to-outer-hood width, multiplied by 100. The horizontal span keeps the value relative to the local eye area rather than to raw photo size. It is a front-view measurement in the Harmony eye group.
Why does FaceIQ Labs measure brow thickness?
- Purpose: FaceIQ Labs measures brow thickness because it describes the visible weight of the brow above the eye. The horizontal 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.
Does Brow Thickness affect my Harmony score on FaceIQ Labs?
No. FaceIQ Labs classes Brow Thickness as a supporting measurement that currently has no weight in the Harmony score. It is also hidden in standard results, so it does not change the numerical Harmony score and does not appear in a standard results view.
What does the Brow Thickness measurement not tell me?
FaceIQ Labs states that its Brow Thickness measurement does not measure hair density or eyebrow health. It is a geometric comparison of vertical brow thickness against a horizontal reference width, not an assessment of brow hair fullness or the condition of the brow area.
What does a worked example of Brow Thickness look like?
In FaceIQ Labs' example, a 6-unit brow thickness over a 30-unit reference width gives 20%. The app averages the left and right percentages. The example values only explain the calculation; they are not a target range and are not measurements of the schematic on the guide.
Where does the Brow Thickness concept come from?
FaceIQ Labs describes Brow Thickness as a FaceIQ landmark-based description of facial shape. The linked research gives background on facial measurement or perception but has not directly validated this exact formula or its score. FaceIQ's score weights and reference ranges are model settings.
What research does FaceIQ Labs cite for Brow Thickness?
FaceIQ Labs cites one source for Brow Thickness: Biller & Kim, 2009, 'A contemporary assessment of facial aesthetic preferences'. It compared ratings of edited brow and nose features on four female models, and the authors emphasized individual facial harmony. It is context for feature relationships, not a test of every brow metric.
Which other Harmony measurements are in the same eye region as Brow Thickness?
- Eye Separation Ratio
- Eye Aspect Ratio
- One Eye Apart Test
- Lateral Canthal Tilt
- Eyebrow Tilt
- Eyebrow Low-Setness
- Brow Length to Face Width Ratio
- Upper Eyelid Exposure
Frequently asked questions
Is Brow Thickness part of my overall Harmony score on FaceIQ Labs?
No. FaceIQ Labs identifies Brow Thickness as a supporting measurement with no current weight in the Harmony score, and it is hidden in standard results.
What landmarks does FaceIQ Labs use to measure Brow Thickness?
It uses the vertical brow thickness from brow peak to arch, compared with the horizontal span from the inner brow to the outer hood, on a front-view photo.
Does a higher Brow Thickness value mean healthier eyebrows?
No. FaceIQ Labs says the measurement does not measure hair density or eyebrow health. A higher value only means a thicker vertical brow relative to the reference span.
Is the Brow Thickness formula scientifically validated?
FaceIQ Labs says it is its own landmark-based adaptation. The linked Biller & Kim (2009) study gives background but has not directly validated this exact formula or score.
