What Is Anterior Facial Depth in FaceIQ Labs' Harmony Analysis?
Anterior Facial Depth, in FaceIQ Labs' Harmony analysis, is a side-view angle measured at the nasal-wing base (subalare), between a line to the tragus (ear reference) and a line to a lower-eyelid landmark. Despite its name, it is an angle, not a depth in millimeters, and it does not use the chin.
Key facts
- FaceIQ Labs measures Anterior Facial Depth as an angle: tragus to subalare (nasal-wing base) to lower-eyelid landmark.
- It is a side-view measurement, listed under Harmony in the Facial Profile group of FaceIQ Labs' measurement guides.
- It is an angle, not a depth in millimeters.
- The measurement does not use the chin and cannot establish forward jaw growth.
- A lower value means the ear and eyelid directions form a more closed angle; a higher value means they spread farther apart.
- FaceIQ Labs calls it a FaceIQ photographic construction; the cited research does not validate this exact landmark formula or its scoring range.
- Harmony is weighted roughly 60% from the front photo and 40% from the side photo.
- FaceIQ Labs standardizes side photos to the Frankfort horizontal plane during landmarking.
What does Anterior Facial Depth measure?
Anterior Facial Depth, in FaceIQ Labs' Harmony analysis, is a side-view angle taken at the nasal-wing base (subalare). It is formed between a line to the tragus, the ear reference point, and a line to a lower-eyelid landmark. FaceIQ Labs lists it under Harmony in the Facial Profile group of its measurement guides.
Which landmarks does FaceIQ Labs use for Anterior Facial Depth?
FaceIQ Labs' Anterior Facial Depth uses three landmarks in sequence: the tragus, the subalare and a lower-eyelid landmark. The subalare, at the nasal-wing base, is the vertex where the angle is formed, while the tragus and the lower-eyelid landmark mark the ends of the two rays. The chin is not used.
Why does Anterior Facial Depth matter in FaceIQ Labs' analysis?
FaceIQ Labs says Anterior Facial Depth links three regions of the side face: the ear, the nasal wing and the eyelid. The positions of all three affect how far the angle opens, giving context about how those regions are arranged. A lower value means a more closed angle; a higher value means the directions spread farther apart.
How is Anterior Facial Depth calculated in an example?
In FaceIQ Labs' worked example, two rays from the nasal-wing base separated by 70° give an Anterior Facial Depth of 70°, regardless of the rays' lengths. FaceIQ Labs states that example values only explain the calculation; they are not a target range and are not measurements of its schematic.
Is Anterior Facial Depth a depth in millimeters, and does it use the chin?
No. Despite its name, FaceIQ Labs' Anterior Facial Depth is an angle, not a depth in millimeters. The calculation does not use the chin, so it cannot establish forward jaw growth. FaceIQ Labs adds that its schematic is not to scale and is neither an ideal face nor a scored result.
Where does Anterior Facial Depth fit in FaceIQ Labs' Harmony scoring?
Anterior Facial Depth is a side-view measurement within FaceIQ Labs' Harmony pillar, which compares 70+ facial ratios and angles to ideal ranges adjusted for gender and ethnicity. Harmony is weighted roughly 60% from the front photo and 40% from the side photo, and side photos are standardized to the Frankfort horizontal plane during landmarking.
Is FaceIQ Labs' Anterior Facial Depth formula validated by research?
FaceIQ Labs describes Anterior Facial Depth as a FaceIQ photographic construction. Clinical profile analysis provides context, but the cited work does not validate this exact landmark formula or its scoring range. FaceIQ Labs says its score weights and reference ranges are model settings, and the cited papers do not collectively validate the scoring system.
What research does FaceIQ Labs cite for Anterior Facial Depth?
FaceIQ Labs cites one source for Anterior Facial Depth: Farkas et al. (2005), 'International anthropometric study of facial morphology in various ethnic groups/races.' It documents variation in facial dimensions across sampled populations. FaceIQ Labs notes that descriptive measurements explain variation and do not establish an attractiveness score.
Which other FaceIQ Labs measurements are in the same region as Anterior Facial Depth?
- Facial Convexity (Nasion)
- Facial Convexity (Glabella)
- Total Facial Convexity
- Facial Depth to Height Ratio
- Orbital Vector
- Interior Midface Projection Angle
- Z Angle
- Eye Protrusion
Frequently asked questions
Is Anterior Facial Depth measured in millimeters?
No. FaceIQ Labs measures Anterior Facial Depth as an angle, in degrees, between the tragus, the nasal-wing base and a lower-eyelid landmark, not as a depth in millimeters.
Does Anterior Facial Depth use the chin?
No. FaceIQ Labs says the calculation does not use the chin, so it cannot establish forward jaw growth.
Is the 70° in the example an ideal value?
No. FaceIQ Labs says the 70° example only explains the calculation and is not a target range.
Is FaceIQ Labs' Anterior Facial Depth formula validated by research?
No. FaceIQ Labs calls it its own photographic construction. It cites Farkas et al. (2005) for background on facial dimension variation, but states the work does not validate this exact formula or its scoring range.
Which photo is Anterior Facial Depth taken from?
It is a side-view measurement. FaceIQ Labs standardizes side photos to the Frankfort horizontal plane during landmarking.
What does a lower or higher Anterior Facial Depth value mean?
A lower value means the ear and eyelid directions form a more closed angle at the nasal-wing base. A higher value means those directions spread farther apart.
