Women should have a waist to hip ratio under 1.0 - a . 90 or lower. That's according to this study - which was done in older people.
A WHR of 0.7 for women and 0.9 for men have been shown to correlate strongly with general health and fertility. Women within the 0.7 range have optimal levels of estrogen and are less susceptible to major diseases such as diabetes, cardiovascular disorders and ovarian cancers.
The closer you can get your waist/shoulder ratio to 1/1.61, the more aesthetically pleasing your body will be. To find out your ratio, measure around your waist, then the circumference your shoulders, (You're probably going to need some help with this part) then divide shoulders/waist to get your ratio.
A waist-to-height ratio below 0.5 is considered ideal. This translates into the health message “keep your waist circumference to less than half your height.” [11] Table 1 shows how to do the calculation for a representative man and women, and how to interpret the risk thresholds.
According to the Heart Foundation, a healthy waistline size is: 37 inches or less for men. 31.5 inches or less for women.
Waist-to-hip ratio (WHR) is a strong predictor of women's physical attractiveness. The “ideal” value varies, but it is always low relative to men's or the average female WHR.
Jodie Comer has been deemed the most beautiful woman in the world according to science and the Golden Ratio. Her face was found to be 94.52% accurate to the ideal proportions, making her the most beautiful woman in the world.
Typically, your measurements are going to be larger than those of a skinny person, and they're going to have a wider ratio between them. For example, take someone with measurements of 42-38-46. They'll fall into the curvy body shape as the chest is over 34, which is typically considered 'skinny'.
The specific proportions of 36–24–36 inches (90-60-90 centimeters) have frequently been given as the "hourglass" proportions for women since at least the 1960s (these measurements are, for example, the title of a hit instrumental by The Shadows).
Usually, we consider hip sizes above 36 or 37 inches curvy and hip sizes below 34 to be a slim silhouette. Also, the waist-to-hip ratios of curvy individuals are often in the range of 0.7 to 0.8.
A 20 inch waist circumference has been achieved by a handful of women using corsets or cosmetic surgery. But it is highly unlikely that most adults could achieve this tiny waist size. For males, it's basically impossible except for young children. And even for females, a 20 inch waist is very rare.
Actress Marilyn Munroe, models Kate Moss, Kelly Brook and starlet Jessica Alba are all thought to have the perfect body shape that gives them a waist to hip ratio of 0.70.
Similarly, the waist measurement of women 18-29 years old is about 71.4 cm, the hip circumference is 88.5 cm. Women aged 30 to 49 years, waist measurement is 76.1cm, hip measurement is 90.7cm and in the final age range, waist-hip measurement is 79.2cm - 90.7cm.

According to an essay on abcnews.go.com, a ratio of 0.8 or less for a woman means you're a pear. Higher than that, you're an apple. A man with at least a 0.9 ratio qualifies as an apple.
The Pear {a.k.a. The Triangle}
Curvy hips, thick thighs, and a full rear are the key characteristics of the pear-shaped individual. Many pear shapes also have a small bust/chest, narrow shoulders {compared to the hips}, and a defined waist.
Two of the most notable pear-shaped bodies include Jennifer Lopez and Beyoncé. Both of these women have narrow shoulders, a defined waist and curvy hips, and they were the first to embrace their curves in an industry that wanted to cover them up.
According to the golden ratio of facial beauty, she is the most beautiful girl in the world. According to a study conducted by Dr.Julian DeSilva, supermodel Bella Hadid has the most perfect face with beauty test score of 94.35%, followed by singer Beyonce and actress Amber Heard.
It works on the premise that the closer the ratios of a face are to the number 1.618 (Phi), the more beautiful it becomes.
As per the report, the 29-year-old Killing Eve star's eyes, eyebrows, nose, lips, chin, jaw and facial shape were found to be 94.52% accurate under the Golden Ratio of Beauty Phi. Following Jodie were Euphoria star Zendaya – who came in second with 94.37% and runway favourite Bella Hadid – at 94.35%.
Research across a variety of cultures has demonstrated that men typically find the curvaceous female form sexually attractive. Other studies have shown that wide hips in women are associated with health and reproductive potential, so the attraction makes evolutionary sense.
Many medical studies show that men find sex appeal with women who are not overweight, have a tiny waist, and larger hips. This was thought to be because it was an indication of health and fertility.
Waist-to-hip ratio (WHR) is a strong predictor of women's physical attractiveness. The 'ideal' value varies, but it is always low relative to men's or the average female WHR.
