The influence of leg-to-body ratio (LBR) on judgments of female physical attractiveness: Assessments of computer-generated images varying in LBR

The leg-to-body ratio (LBR), which is reliably associated with developmental stability and health outcomes, is an understudied component of human physical attractiveness. Several studies examining the effects of LBR on aesthetic judgments have been limited by the reliance on stimuli composed of hand-drawn silhouettes. In the present study, we developed a new set of female computer-generated images portraying eight levels of LBR that fell within the typical range of human variation. A community sample of 207 Britons in London and students from two samples drawn from a US university (Ns = 940, 114) rated the physical attractiveness of the images. We found that mid-ranging female LBRs were perceived as maximally attractive. The present research overcomes some of the problems associated with past work on LBR and aesthetic preferences through use of computer-generated images rather than hand-drawn images and provides an instrument that may be useful in future investigations of LBR preferences.
