Global & US Bra Size Breakdown
After searching exhaustively through market research databases, academic research databases, and company websites and reports from the women's bra industry, we were unable to find conclusive data to create a breakdown of women's bra sizes. While we were unable to find enough data to provide a breakdown of bra sizes of women both globally versus the US, our research revealed data on average bra sizes globally by European standards and A Sophisticated Pair's publicly available breakdown of sales by cup size and band size.
BRA SIZE BREAKDOWN
- These bra size findings are based on European standards. They were all derived from a scientific study published in the Journal of Female Health Sciences.
- Women in 14 countries out of 104 have an average breast size of less than A.
- Women in 30 countries out of 104 have an average breast size of A.
- Women in 40 countries out of 104 have an average breast size of B.
- Women in 5 countries out of 104 have an average breast size of C.
- Women in 11 countries out of 104 have an average breast size of D.
- Women in 2 countries out of 104 have an average breast size of E.
- Women in 1 country out of 104 have an average breast size of more than F.

Our surface-level search strategies didn't return anything valuable on our topic. Since we are specifically searching for information other than an average, we ventured toward a more advanced search methodology.
As our first strategy, we scoured the databases of some popular bra selling brands. Our hopes were to get size by size sales statistics from their websites. We would have used these statistics to triangulate the required breakdown of bra size of women. We searched the websites of brands like A Sophisticated Pair, Victoria's Secret, Triumph International, Knix, Jockey, Calvin Klein, Thirdlove, Amante, Pretty Secret, Clovia, Addition-Elle, The Natori Company, Hanes, Wacoal, Maidenform Brand, Fantasie, Vanity Fair, Trusst, Lively, Wonderbra, and Playtex, among others. We searched their blogs and went through their financial releases wherever available to find sales breakdown by size. Except for A Sophisticated Pair, no other company had any legible data on sales broken down by bra size. The data on the blog of A Sophisticated Pair is from 2016, making these findings less applicable in the current world scenario. We have included the findings from A Sophisticated Pair in the helpful findings above. The store only operates in the US.
After not finding any recent sales breakdown by bra size, we shifted our strategy to search market research websites. We hoped to find a market-wise breakdown of bra sizes on these websites. We would have then used this data to triangulate the breakdown of women's bra sizes. However, we could not find any productive information from these market research websites, as they were paywalled.
We next turned our attention to academic research and statistics websites, hoping to find any studies conducted that include a breakdown of bra sizes on the basis of demographics such as age, geographic location, ethnicity, etc. We could not find any data that was applicable to our client query. We did find a source on Statistics Brain, that seemingly had data on breast size distributions. However, the source was paywalled.
We also searched health websites like the World Health Organization (WHO), the Journal of Female Health Sizes (JOFHS), and the Breast Cancer Foundation. We hoped to find a percentage distribution of breast size among women to help us find relative bra size distribution. These sites had data and statistics on breast cancer, average breast sizes, development of breast sizes in different parts of the world, and similar studies available. But, there was no data that could provide us with a distribution of women's breast sizes by age or any other metric. There was only a single study conducted by JOFHS in 2013 regarding breast size distribution all around the world. Its findings, however, are not entirely available to the public. Only the average for each country is provided. We have included them in the helpful findings above.
As a last resort, we tried to search for bra/breast size percentile distribution to triangulate percentage distributions from these percentiles. We did get a lot of misleading results related to measuring bra cup size, but none provided a percentile distribution graph, cart, or curve.
Thus, we concluded that data to support a breakdown of women's bra sizes of women by different metrics has either not yet been collected or is not yet publicly available.
