As quoted from Standard.co.uk, perfect buttocks have WHR (waist-hip ratio) 0.7. WHR is a measure of the ratio between waist and hip. To calculate it, the waist circumference is divided by the circumference of the hip.

While in today's generation, buttocks model and actress Rosie Huntington-Whiteley is considered the most perfect. Lover actor Jason Statham has a waist circumference of 25 inches and hips 35 inches. If divided, then Rosie's buttock has a ratio of 0.71.

Beyonce also became a celebrity with the size of the butt closer to perfect. 26-inch waist and hips 40 inches so that the ratio of the buttock 0.65. Other celebrities who also have a perfect buttock ratio is Megan Fox and Jessica Alba.

The results of this study reinforce previous studies conducted Barnaby Dixon, an anthropologist from New Zealand. The results reveal that men are most interested in women with large buttocks, which has a ratio of 0.7 from waist to hip.
