What is the average bra size?

Women are programmed since an early age that breast size and bra size are closely aligned with femininity and being attractive. There is the concept that bigger is better, which is the reason for so many implants.

Women’s bodies are different so there may not be an average bra size. Statistically speaking though, there is. According to the Huffington Post in an article by the lingerie company Intimacy, the average bra size is 34DD. It has jumped from a 34B 20 years ago to a 34DD in 2013. According to the study and the article, weight gain and breast implants have played a role in the increase in average bra size.

The biggest factor is that women are choosing a more appropriate size. “Women are more educated about bra fit” Intimacy spokeswoman Kate Terhune stated to the Huffington Post. This matches our research which indicated most women wear bra sizes that are too small and constricting. Average bra size would increase, now that women are more educated on bra fit and sizing. This cup size figure 34DD is current, based on our research.

Back to the study though, Intimacy interviewed more than 60,000 customers at its 16 stores nationwide in determining the average bra size, and compared the results to a similar study it did in 1992. Far more bra sizes are available now and the results are clear, the average bra size is 34DD.

On a cultural note, some studies show that women with larger breasts and bra size are perceived as unintelligent, yet more desirable by men. Whereas women with smaller breast are viewed as more intelligent and often regarded as the girl next door. Where does that leave the woman with average bra size? Regardless, most women are ashamed of their bra size feeling that too small or too large determines their self-worth. Maybe average bra size is best! In reality though, body frame, height, and genetics all have a factor in determining bra size.

Many women also find that after being properly fitted they are actually a larger size than the bra they wear. The end result can often lead to more self-confidence when their clothes fit better and they actually feel better as a result of the correct bra size.
