By Global Curves: New Data Reveals Diverse Bra Sizes Around the World
A comprehensive survey of bra sizes from over 100 countries has shed light on a topic as personal as it is cultural, revealing striking differences in average cup sizes across the globe. The data, compiled from multiple smaller-scale studies and presented on WorldPopulationReview.com under the heading “Bra Sizes Around the World,” indicates that average breast sizes vary widely—from a modest AA to a fuller C—reflecting not only genetic differences but also lifestyle and nutritional factors.
In North America and parts of Europe, the numbers point to larger averages. Women in the United States and the United Kingdom both boast an average cup size of C, with average BMIs of 29.0 and 27.1 respectively. “These figures underscore how regional differences in body composition and lifestyle play a key role,” said Dr. Jane Thompson, a researcher in human biology. “Higher BMIs in these regions contribute to larger breast sizes, which are statistically reflected in the data.”
Other Western nations also cluster in the higher range. Venezuela, Colombia, Canada, and Georgia show averages in the B-C range, with Georgia notably averaging a B cup at a BMI of 27.7. Across the Atlantic, countries like Sweden, the Netherlands, and Bosnia and Herzegovina report similar measurements, although Switzerland trends slightly lower with an average B cup of 23.8.
Conversely, many African and Southeast Asian countries register significantly smaller average cup sizes. In countries such as Ethiopia, South Korea, and Vietnam, the data consistently falls into the AA or A category. Experts attribute these differences partly to genetics, noting that women in these regions tend to be smaller overall. Additionally, active lifestyles and lower average BMIs are believed to contribute to the smaller measurements.
“It’s not just about aesthetics,” explains cultural anthropologist Maria Lopez. “The correlation between BMI and breast size reveals much about nutritional status and lifestyle. In regions where physical activity is a larger part of daily life, and overall body mass tends to be lower, you see these differences clearly reflected in bra size averages.”
The survey, which analyzed data from 108 countries, also highlighted that the dataset does not capture every nation. For example, Norway—likely to share similar trends with its Nordic neighbors—was not included. “In future studies, a more complete dataset might reveal even subtler regional patterns,” Lopez added.
While the findings have generated widespread interest and conversation online, few credible studies have explored average breast size on such a global scale until now. The compilation of this data into one comprehensive source offers a new perspective on how human bodies vary across different cultures and environments.
From the fuller curves of the United States and United Kingdom to the more modest profiles seen in many African and Southeast Asian nations, the numbers tell a global story of diversity in body shape and size—a story shaped by both our genes and the environments in which we live.
Data from Target Map has revealed that women with the biggest boobs live in Finland, Norway, Russia and Sweden.
On average, woman in those countries have a bra cup size larger than a D.
The UK, in comparison, has an average size of a C cup.
The majority of women in African and Asian countries inclding Sri Lanka have an average cup size of A or B.
