Average breast size worldwide

As a supplement to the average penis size, there is now also the average cup size by country of origin.

This international comparison shows not only the pure letter of the garment, but much more accurate the actual breast volume per country.

Globally speaking, the average volume of the natural female breast is around 327 milliliters. This corresponds to the European standard size B.

By far the largest breasts are found in North America, the smallest in Asia. With an average volume of 1494 ml and thus cup size F the women from the United States rank 2nd in this comparison of 105 countries .

There are numerous listings on the internet to illustrate breast sizes by country. Unfortunately, almost all are based on a single evaluation at Targetmap, which appeared in 2010. As author, only 'yarkko' is named and his sources are unnamed. The following evaluation is not only proven by sources, but with the indication of the average volume in milliliters even more accurate.

Our evaluation is based on a study from 2013 that has been published in the "Journal of Female Health Science".

International bra sizes

The starting point was that most of the publications were based on data from bra manufacturers and therefore only indicated the coarse cup size. Confusion is also regularly caused by the different sizes and scales. For example, the US size 'C' already corresponds to the EU size 'E', which again leads to mistakes. All bra sizes mentioned on this page are consistent with European standard sizes.

For the United States, women were separated according to their race: Caucasians (white) and Non-Caucasians (black and others). Caucasian Americans have by far the largest breasts with an average cup size of F and above.

That's how it was measured

In more than 100 countries, women's bodies were measured using mostly 3D body scanners. In the evaluations there are no self-assessments, but only results of medical professionals. All subjects were between 28 and 30 years old and were divided according to their country of birth. All women were in normal health, not pregnant, not lactating, hormonally treated and had no breast surgery.

Already in the published study numerous measurement results were discarded because they were too inaccurate or the measuring methods were not accepted by the scientists. Out of the remaining results, some countries were also taken out here, because of low amounts of fewer than 700 women per country. Overall, more than 340,000 measurements from 105 countries remain.

Faulty self-assessments

In many studies, women were additionally asked about their own cup size. In most cases, the answer turned out to be indicative. Sometimes the answers were rather imaginary and often had little to do with the actual size. The most common reason for this is that women often wear too large bra sizes. This has financial reasons, especially in less developed countries. In more developed countries, women are more likely to use the services of specialized shops, resulting in appropriate sizing of dress sizes.

Results in the USA

For the United States of America, women were separated by race: Caucasian (white) women and non-Caucasian (black and others). Caucasian Americans have by far the largest breasts with an average cup size of over F. All bra sizes used here refer to the European standard sizes, the scale of which, however, ends at F.

Bra size and obesity

Obesity by country It is noticeable, that increased breast sizes often occur in countries where obesity is also a problem. To illustrate this, the average BMI (body mass index) of women was shown in an additional column of the table. Unfortunately, this BMI is not available separatedly for Caucasian and Non-Caucasian women. The average BMI of all women in the US is 29.0, which is very high. Nevertheless, the study indicates that the ratio of large breasts to obesity is lower in the US and Canada than in other countries. 52% of women born in the USA with a BMI of 21-24 would therefore already have a bra size of F or greater.

Breast forms

The study results also show a certain relationship between the origin and the shape of the breasts. Especially in the US, the breasts are predominantly hemispherical, while in other countries they are usually pear-shaped. Outside the US, the largest 25 percent were classified as "hanging" or "saggy". For all North American women even the breasts, which are oversized by European standards, are still round. This also implies a different position and direction of the nipple. In the US, on average, it points slightly upwards and is about 3.8 cm above the center of gravity. In the average of all other countries, it points slightly downwards and is over 2 cm below the center of gravity.
