Nasal Width-to-Height Ratio
Side-view horizontal nose reach relative to the vertical distance from eye front to nose tip.
What is measured
The calculation
|Tip x − subalare x| ÷ |corneal-apex y − tip y|
Side view / Measurement guide
Follow the measurement
Select a label to focus on its line. Select again to show all measurements.
In these guides, 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 compares the nose’s horizontal reach with a vertical eye-to-tip reference. It differs from the frontal nasal width and from the constructed length used for Nasal Projection.
- Lower: less horizontal reach relative to eye-to-tip height.
- Higher: more horizontal reach relative to that height.
Where the idea comes from
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. [1]
A worked example
A 30-unit horizontal reach and 40-unit vertical separation give 0.75.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.
Research & further reading
The sources below explain the history or related evidence. FaceIQ’s score weights and reference ranges are model settings; these papers do not collectively validate the scoring system.
