Is a Waist-to-Hip Ratio of 0.7 Truly Preferred?

Analyzing University Students’ Response Using Figural Stimuli Based on Objective Measurements.

Abstract

This study aimed to elucidate the influence of waist-to-hip ratio, waist-to-bust ratio, and body mass index on the evaluation of attractiveness, using figural stimuli derived from 3D computer-generated images created based on objective measurements. In this study, not only the evaluation of attractiveness but also several other assessments of body image (e.g., perceptions of an average body shape) were examined. Japanese university students—168 men (mean age 20.49, SD = 1.33) and 239 women (mean age 20.08, SD = 0.99)—participated in the survey. The analysis results indicated that, across genders, smaller hip sizes were perceived as more attractive. Additionally, larger bust sizes and slender physiques were considered more attractive. Notably, average perceptions varied between males and females. The study highlighted potential cultural variations in attractiveness standards concerning the waist-to-hip ratio. Furthermore, it suggested that standards might be subject to alteration based on race when conducting evaluations about the body.
