Why It Matters
The measurement helps describe the nose's width-to-length balance in a front-facing photo. It is most useful alongside bridge, midface, and mouth-width proportions.
How It Is Calculated
The test measures alar width between both sides of the nose and divides it by the nasion-to-tip distance, then multiplies by 100.
