Globally, a natural female breast has an average size somewhere between a large "A" and a smaller "B" in the US size system. According to European or Australian classifications, this would be a "B".
Australia - B (26.8) Bosnia and Herzegovina - B (25.3) Switzerland - B (23.8)
When our participants were asked what their ideal breast size would be, the C cup was considered the most popular, with 39% choosing it above other sizes.
Average Cup Size
According to a survey conducted between 1992 and 2013, the average bra size in the U.S. has increased from a 34B to a 34DD, and now just six years later, the average has shot up to a DDD — that's the largest compared to any of the other countries studied.
It turns out, over half of women polled thought a C cup was the perfect fit. At the same time, close to 26 percent preferred a B cup. Nearly 2 percent said an A cup was their preferred breast proportion.
Understanding “Ideal” Breast Size
Likewise, 49% of men and 52% of women concurred that a C cup is the ideal breast size, which is close to the average breast size of women in both the United States and Europe.
Changes to your breasts are a normal part of aging. Changes in firmness or size are very common, especially after menopause. However, some changes can be a symptom of health problems, and it's important to know when you should be concerned.
It has been previously suggested that female breast morphology arose as a result of sexual selection. This is supported by evidence showing that women with larger breasts tend to have higher estrogen levels; breast size may therefore serve as an indicator of potential fertility.
The women with the largest breasts are from Russia, Sweden, Norway and Finland, who, on average, have a cup size larger than a D. Women from Africa or living in Asian countries are on the opposite end of the spectrum - the majority with A or B cup sized breasts.
There is a vast spectrum of different sizes and shapes. In fact, the Guinness World Record for largest natural breasts belongs to New York native Annie Hawkins-Turner. Her chest-over-nipple measurement is 70 inches!
According to a study conducted by the researchers at the University of Vienna, smaller breasts are likely to be more sensitive than their bigger counterparts. They are also more likely to get easily aroused for increased pleasure.
Australian bra sizes typically range for band sizes from 8 (25-27 inches) to 26 (43-45 inches).
For less than one inch you are a AA cup, for one inch you are an A cup, for two inches you are a B cup, for three inches you are C cup, for four inches you are a D cup and for five inches you are a DD cup.
The main reasons why women's breasts get bigger as they get older are: Weight gain or weight redistribution. Fluctuating hormone levels due to menopause.
The transition through menopause may cause several changes to the breasts, potentially affecting their shape, sagginess and texture. They might even noticeably increase in size, with many women going up by two bra sizes or more.
As oestrogen goes AWOL, breasts go through a process called 'involution' where milk glands shut down and this tissue is replaced by fat. Weight gain also causes an accumulation of fat cells, and some of these camps out in your bra. Many women get bigger all over as their oestrogen stores get smaller.
There's no specific age when your breasts will start to sag. It's common for some droop in your 40s and beyond, but many women experience saggy breasts earlier. If you're lucky enough to escape the droop in your 30s and 40s, you'll most likely notice changes in elasticity and fullness as menopause approaches.
No. A girl's bra won't affect the growth of her breasts. That's because genes and hormones control breast growth, not what a girl wears. Bras don't make breasts grow or stop growing, but wearing the right-size bra may help you feel more comfortable.
Gigantomastia or breast hypertrophy is a rare condition that involves developing extremely large breasts due to excessive breast tissue growth. It affects people assigned female at birth. If you have gigantomastia, you'll experience rapid and disproportionate breast growth.
When you look down at your bra do you notice space between your breasts and the cup? If so, it's too big. If you aren't able to see any gaps while standing up, try leaning over while looking into a mirror. If there is extra space in your cups it's time for a new size.
Bra Cup Sizes
The further down the alphabet a letter is, the larger the cup volume, starting with AA as the smallest. Some cup sizes have double letters (like AA, DD, or FF) and some just single letters.
