Kim Kardashian, Beyonce and Jennifer Lopez – their trademark is their bottom. But what makes the perfect butt? We explain how you can calculate it.
British scientists claim to have found the formula for calculating the optimal hip-to-waist ratio. To do this, researchers from the “University of Lacashire” measured and examined more than 2,000 women. The result is a formula that attaches value to the female bottom. From this, an index was developed that contains a scale. The perfect scale value is 0.7. The fact that this value probably applies to very few women should not surprise anyone. The female society average moves around this value towards both extremes of 0.0 and 1.5.
waist circumference : hip circumference = bottom value
In words: The waist measurement is divided by the hip measurement and gives a butt result. Measurements are taken at the narrowest part of the waist and at the widest part of the hips. With the optimal value of 0.7, the perfect woman would have to have a waist circumference of 70 centimeters and a hip circumference of 100 centimeters, according to Adam Riese.
Which type is yours?
But even the optimal value of 0.7 on the index can take on a wide variety of characteristics. There are four categories that serve to classify: apple, pear, tomato and potato shape.
apple shape:
The smallest of its kind is the apple butt. Narrow, tight, but relatively small. Almost ten percent of all women are affected.
Pear Shape:
Characterized by a narrow waist and a wide pelvis is the pear bottom. Around 15 percent of all women have this bottom.
Tomato shape:
This variant is the most common! Based on the fruit, the tomato bottom is very round. Whether the curves are tight or rather slack depends on the woman.
Potato Shape:
This expression can be found in around 30 percent of all women. The potato bottom is relatively large and elongated.

Contrasting study from Texas
Scientists from the “University of Texas” do not agree with their British colleagues. Their point of view on the perfect butt refers to the curvature of the rear. An angle of 45.5 degrees between the spine and buttocks is optimal and is perceived as extremely attractive.
