Nasal Projection
How far the nose tip extends in front of the nasal wing, relative to a constructed nose length.
What is measured
The calculation
Horizontal subalare-to-tip projection ÷ tip-to-extended-dorsum length

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
Scaling projection by nose length distinguishes a long nose with proportional reach from a short nose with the same forward reach. Projection and rotation describe different aspects of the tip.
- Lower: less forward tip reach relative to the constructed length.
- Higher: more forward tip reach relative to that length.
Where the idea comes from
FaceIQ adaptation
Projection-to-length ratios are used in rhinoplasty assessment. FaceIQ extends the tip-to-rhinion direction to nasal-root height for its denominator; that construction is not interchangeable with every clinical projection method. [1]
A worked example
A 30-unit horizontal projection divided by a 50-unit constructed length gives 0.60.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.
