Intercanthal-Nasal Width Ratio
Nose-base width divided by the gap between the inner eye corners.
What is measured
The calculation
Alar nose width ÷ inner-eye-corner distance

Why it matters
It relates the nose to the eye region immediately above it. A wider nose and a narrower inner-eye gap both increase the number, so the result cannot identify either feature in isolation.
- Below 1: the nose base is narrower than the inner-eye gap.
- Above 1: the nose base is wider than the inner-eye gap.
Where the idea comes from
Classical proportion
The comparison between nasal width and inner-eye spacing is a classical proportion canon. FaceIQ divides nose width by eye gap; check the order when comparing with other sources. [1] [2]
A worked example
A nose 35 units wide and inner-eye gap of 32 give 35 ÷ 32 ≈ 1.09.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.
