More than Just One Number: The Limitation of Using 2D Width Measures as Indicator for Body Attractiveness
SymposiumTalk-05
Presented by: Emily Ufken
The viral A4 waist challenge exemplifies the social media-driven pressure to achieve extreme thinness, promoting a dangerous ideal where the waist must be narrower than a 21 cm sheet of paper. This focus on minimal, two-dimensional (2D) measurements regarding female body attractiveness perception raises critical questions about how perceived body shape differs from physiological reality, particularly regarding the widely-studied Waist-to-Hip Ratio (WHR). In order to investigate this, we conducted an online rating study, using a set of 30 real women’s bodies varying in weight and WHR, thus body shape.
Our results show, that while 2D WHR explains more variance in attractiveness ratings than actual 3D WHR, 2D WHR measurement systematically produces lower WHR values. Moreover, adding shape information that not only account for width, but also for height ratio between waist and hip further increases the prediction of attractiveness ratings.
These findings highlight the limitations of using 2D WHR values and suggest a need to first revise the widely established ideal WHR of 0.7 when considering actual 3D body shape and second, to include more complex shape information into the evaluation of body attractiveness.
