Nasofrontal Angle
The angle at the nasal root where the forehead meets the upper nose.
What is measured
The calculation
Angle: glabella → nasion → supratip
Side view / Measurement guide
Follow the measurement
Dots mark the landmarks. Lines show how the measurement is taken.
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
The brow-to-nose transition influences how deep the nasal root looks. Both brow prominence and nose-bridge direction change the angle.
- Lower: a more closed angle at the nasal root.
- Higher: a more open transition from brow to nose.
Where the idea comes from
Clinical reference
Nasal angles and projection are used to describe profile shape. Preference studies have tested edited noses; FaceIQ’s particular landmarks and score ranges should not be treated as universal conclusions from those studies. [1]
A worked example
An angle of 120° is more closed than 140°. These are illustrative angles, not a prescription for a particular face.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.
