Summary

Katy Perry's mouth width to nose width ratio measures 1.48x, scoring 9.2, which places her higher than 60% of the women on the wiki but below the ideal range of 1.52 to 1.60x. Her value matches that of Ana de Armas, Anya Chalotra and Ariana Grande, while Madison Beer records the highest figure on the wiki at 1.76x and Rihanna the lowest at 1.23x. The measurement assesses oral-nasal harmony, comparing mouth width with inter-alar (nose) width. Balanced ratios avoid disproportionate sizes, and females typically score higher with narrower noses.
