Snapshot of the software used to measure male preferences for body shape.

<p>The left picture represents a silhouette corresponding to the male (here: stature = 183.0 cm, BMI = 23.6 kg/m²), and the right picture represents the silhouette of his ideal female partner (stature = 169.3 cm, BMI = 18.3 kg/m²). Dials under the pictures enable the user to modify the BMI according to his self perception, and it enables him to adjust the stature and body mass of his preferred female as well.
