In the era of social media and heightened body awareness, images of women with diverse body types—particularly curvier figures—have become increasingly common. While some online content sensationalizes these traits, it’s important to approach the topic respectfully and factually. A woman’s body shape, including having wider hips or a larger gluteal area, is influenced by genetics, hormones, lifestyle, and overall health—not by unsubstantiated or suggestive assumptions.
This article explores what current research and health experts say about body composition, hip-to-waist ratio, and socio-cultural perceptions of curvy body types, drawing from verified sources such as the World Health Organization (WHO), Harvard Health, and peer-reviewed medical studies.
What Determines Body Shape?
A woman’s body shape is primarily influenced by genetics. Factors such as bone structure, fat distribution, muscle mass, and hormonal balance all contribute to whether someone naturally has a pear-shaped, apple-shaped, hourglass, or rectangular figure.
Estrogen, the primary female sex hormone, plays a key role in fat distribution. During puberty and adulthood, women tend to store fat around the hips, thighs, and buttocks. This fat storage is part of normal biological development and may serve reproductive and metabolic purposes.
The Role of the Gluteal Muscles
The gluteus maximus, gluteus medius, and gluteus minimus are the three main muscles that form the buttocks. These muscles are essential for posture, balance, and everyday movement, such as walking, climbing stairs, or lifting objects.
A person with more muscular glutes may appear curvier due to exercise and resistance training. Conversely, fat distribution in the gluteal area can vary depending on metabolic rate, diet, and hormonal levels.
Physical training programs like squats, lunges, and hip thrusts can help build strength in this region, which is why fitness professionals often focus on glute training for both aesthetic and health reasons.
Waist-to-Hip Ratio: A Health Indicator
One measurement used in health assessments is the waist-to-hip ratio (WHR), which compares the circumference of the waist to that of the hips. According to the World Health Organization, a WHR below 0.85 in women is generally considered a healthy indicator for reduced risk of cardiovascular disease and metabolic disorders.
It’s essential to understand that WHR is a health metric, not a beauty standard. While lower WHR is associated with lower health risk in women, it is only one factor among many. Body mass index (BMI), physical activity level, blood pressure, and cholesterol also play vital roles in assessing overall health.

Cultural Perceptions of Curves
Across history and cultures, the ideal female body type has varied. In some societies, curvier figures were traditionally viewed as symbols of fertility, wealth, or strength. For example, in African, South American, and Mediterranean cultures, fuller hips and buttocks have been celebrated attributes.
However, media portrayals of body image have often promoted unrealistic or homogeneous beauty standards. In recent years, there has been a growing movement to embrace body diversity. Campaigns led by organizations like Dove’s Real Beauty, Body Positivity Movement, and various fitness influencers are helping normalize all body types, including curvy, lean, muscular, and plus-size bodies.
