I figured since I did a post on average penis size a little while ago, I’d even things out and do one on average breast size. I mean after all, how often do we hear about breasts in America, amirite? 
Studies of average breast size don’t appear to be standardized very well. What is considered a 34B in many Asian countries, may not be a 34B in, say, Germany – or even between companies of the same nation. In fact, a number of studies aren’t actually scientific, but rather based upon bra sales:
Lingerie manufacturers report the most common bra size sold in 1996 was a 34B. While this is not scientific data, it is supported by data from the UK which shows the most popular bra size to be 36B.
I was about to speculate on the slight discrepancy between what was sold and what was actually studied, but then I realized that I’ve never bought any lingerie or bras. I swear. So let’s just say it was chance.
In more recent studies, it was found that breast size has generally been increasing, especially in Asia:
Similar data about the increase in average breast size comes from the UK, where busts grew from 36B to 36C between 1997 and 1999. According to The Penguin Atlas of Human Sexual Behavior, breasts across Asia grew from 34A to 34C between 1980 and 2000. It seems that the average breast size is increasing around the world.
Similar but less dramatic results were found in the U.S. where cup sizes increased from B’s to C’s. Now, despite the picture of the topless woman measuring her obviously augmented bust at the previous link (don’t get too excited, it’s censored…plus you have Google available to you anyway), it clearly isn’t that implants are on the rise and thus causing an increase in overall bust size. It’s probably just that we’re all getting fat. But there are other theories:
Some fashion designers believe that the increase in average breast size is a result of the garment industry. Many clothing manufacturers inflate or deflate sizes according to the times. As all women know, different brands of shoes and clothing fit differently. There’s a big difference in a size 10 from two different companies. And as larger breasts have become more fashionable, possibly C cups have been getting smaller so more women can be proud to have a larger than average size.
The governor of Maine may even be contributing to larger breasts:
A final, and far more terrifying, explanation is that of excessive estrogens in the environment. Due to industrial pollution and widespread use of oral contraceptives, there are high levels of estrogens found in water in many places. In some rivers, fish are dying out because there’s so much estrogen in the water that all the fish are born female. In this scenario, average breast size is growing due to this hormonal pollution.
As all Mainers – and Comedy Central viewers – know, Gov. LePage recently said BPA containing bottles have been known to release estrogen. He believes this will give women beards. Of course, he isn’t well-versed in science, so let’s ignore him there. But let’s not ignore there could be a multitude of factors contributing to increased bust sizes.
From what I can gather, it looks like the general consensus for American breast size is in the C range, usually 36C. I wouldn’t be surprised to see this number increase with time, especially since we aren’t doing much about the continuing obesity epidemic. But fear not insecure women out there, for large breasts are not necessarily nice breasts, nor even desired breasts. Given that the average among thin people is probably significantly less than the overall average, my guess is that most guys, on a simply physical basis, would prefer a woman with a smaller cup size if that meant that she would also be in better shape. In other words, there’s no need to be insecure about breast size. Just be insecure about waist size, is all. I’m sure that has never caused anyone any anxiety anyway, right?

First, I don’t believe you have never bought a bra for personal use.
Second, where’s the study on how tissue purchases have contributed to bra size purchase?
It’s juxtaposed with the section about sock size and penis size.
I don’t like clicking links. I’m philosophically opposed.
I actually am delighted that I have small breasts beacause I look thinner, can run without jiggling, and my shirts fit me all the way. It’s weird how people think Ds are pretty, while As look much better.
I was waiting for some wag to say, “And this is a problem how?”
Actually, I have met small-breasted women who are so incredibly sexy they just want to make you melt in your boots.
Well I love my natural D breasts.They are soft,and bouncy, and beautiful.Men fall over themselves to talk to me, and I’ve never had any complaints ever!
First, nice article. It’s hard to find men that aren’t pigs these days. :]
Second, Busty Betty, when you say ‘natural’, do you mean ‘I’m a sloppy fattie that eats corn dogs every hour, and since the only thing I actually have (besides my bulging stomach, my flat and cottage cheese-like bum, and my triple chins) are ‘big, natural breasts” by any chance? I have a feeling that’s what it is. :]
Try to put down the fork, run for an hour like I do, and eat what you’re supposed to, and THEN come back and measure yourself. If you’re bigger than a 36C, bigger than I am, then go ahead and boast.
Until then, choke on some three-day old gravy for me, sweetie. ;)
P.S: It’s funny how you’re so willing to tell your boob size, but you hardly tried to tell your pant size.
Btw, I’m a size 4, 36C. And real men that are educated and nothing like horny 14 year olds ‘fall over themselves to talk to me’ (not my body, my face).
Have a blessed day.
Pretty Jenny? You start off by saying, “It’s hard to find men that aren’t pigs these days.” Then end with, “real men that are educated, fall over themselves to talk to you?” After ready the hurtful, and nasty way you talk to people. I would say you could be the most beautiful woman in the world, and maybe men do flock all around you. BFD!!! I would also have to say, then they find out your a whore, and a total BITCH because of how easily your mouth and your legs are always wide open. I don’t see what your point in talking to Busty Betty like that was, other than to make yourself feel better about the way you are? Beauty is on the inside as well as the out, the sooner you learn that the better off you will be.
OH AND P.S. A PERSON WHO IS TRULY A SIZE 4 IS NOT NEEDING 36 INCHES TO GET AROUND THE RIB CAGE, TRY AGAIN, “SWEETIE”
Well. This took an interesting turn.
^Yep. People will fight over anything on the internet..
Well.. heres my thoughts(If anyone is generous enough to give a crap)
But me, being a guy, believe beauty and love stems from 100% inside.
Id never chose a girl with huge breasts and a skinny waist over one who i could trust and confide in.
I know this isnt 100% true. But people who are self confident with thier looks to the point they want to show it off constant, take pride in guy after guy falling for them and intentionally hurt people less “lucky” in the looks department.
For example.
Take the type of woman “PrettyJenny” Described and weigh her up agaisnt Jenny herself.
Someone who would be less secure with thier looks vs someone who boasts about it.
I Personaly couldnt care if the first woman(il call her Anne from now) had absolutly no breasts, two enourmous breasts(But didnt try to flaunt them ofcourse). Or even one of each. If she could make me happy inside. If She knew how to make me smile. If she took the time to care about me and how i felt etc etc. Someone who i could hopefully someday call my wife.
Shed be the correct choice in my opinion over having someone who is going to be perved on by each and every guy.
Point of the story is, if there is any girl or woman reading this and feeling insecure.
Dont be insecure. Because there are people out there who care. And you yourself dont try to get the most popular guy all the rest of the girls want. Odds are hes going to be the type of guy girls have gotten to usto calling “pigs”.
In the end, looks never matter.
Would you want to look back on life and think.
1- I made him happy
2- I made him want to have sex with me
Sorry for the big rant but hopefully some young girl or even mature woman can find a new way of thinking and feel happier about themselves.
FYI-
Growing up, I was one of the “good looking” guys in school. But I never made a move with anyone,i turned them all down. For some simple reason, The girls who were interested in me, Didnt care about me. They just wanted me because it was a “trend” i guess.
It wasn’t until i was 18 before I found someone i knew genuinly wanted to be with me. Who didnt care what i looked like.
Now 12 years on.
I will be celebrating my 10th year wedding anniversary with my one and only true love.
Good Luck Finding love people. Its the best.
educated men?? what does education have with being attracted with large breast lol! the premise does not lead to the conclusion.
smaller defintely better As are awesome and Bs are beautiful!
