How Big Should A 12 Year Old's Boobs Be?

Well..I'm a 30a. And tbh, mine are quite flat and I'm twelve. Don't worry about it! They will soon grow, and then you will be wishing they didnt. Ive started puberty but my boobs are completley flat tbh. Woah. Some of you are like 36 something? Gosh, thats abit big. Anyways, don't worry bout it darling.

Everyone grows at a different rate, don't worry.
I'm a 34C and I'm 12.
You will grow :)

Hey! Thought you might like a guys opinion. I'm 12 and tbh I don't think it really matters and boys that say it dose are trying to look big infront of there friends trust me it's a boy thing :D

Hey, I am 12 and my boobs are a size 36a I really wish they would grow I even tried rubbing oil on them but nothing happened don't worry about your boob size its all ok your boobs will grow when they grow I know it isn't what you want to hear but thats all  the truth.And if you are really worried about your boobs talk to your mom maybe she will get you some growing boob pills.
  K bye talk to you later!:)

Iam 12 and iam a 36b a guy  asked me to show  him my boobs and I  punched him  now he had a black eye so  just be urself  if dose  not matter what people think  just be your self thats  what  I do and a lot of guys asked me to our school dance

My boobs are a 30 A/B. I really don't get why ppl want big boobs. Big boobs run in my family and I'm not really fat just have massive boobs! Most ppl in my class are flat or 28-36 and AA-C. I think most ppl are pretty no matter what the size of there boobs. As long as they are not hueting your back and you can fit into most tops then you are pretty much fine. Nobodys perfect and I havent 1 single person in my life who was actually happy with their boobs. Theres no point in being unhappy about them because they are not going to change over night! Just try to be positive about them! :D xxx

I am a 32C and I am 12 I am the biggest of my friends but everyone grows at different rates. Don't worry if you are flat chested they will come. If they are big then that's fine to most of your friends will catch up with you. So don't worry about what size you are. I also came from a small primary and all my friends were tiny and flat chested! I was worried then but when I got to secondary school I realised I wasen't the only one my age wearing a bra.

From a 12 year old guys perspective, sure we look and talk but that's not important compared to all the other aspects of girls, like personality.

I am a 36a and my boobs and not big at all I want the to look full not a flat as the table

I have 36A and mine are normal, I am also 12. But all my friends are like, 36AA.

All girls bodies develop at different rates. Don't worry. You'll become a young woman soon enough

Well I'm a 36d 5'4 and 115 lbs n to be honest I love it:)

Well I am 11 going on 12 in a couple of months I am almost completely flat chested  (28 A - 30A) its quite annoying but I also havent started puberty yet so its know wonder they havent grown      thing is don't worry about it  x

I'm twelve and I am going to the seventh grade and I am 32A its horrible because all ive grown up around with boys because I have no sisters or girl cousins and all my friends have no boobs or they are really tiny! Boobs are really uncomfortable :( it looks really weird too help meh!!!

Mine are 36 A. I think they are perfect because every one is different.

Mine are 32a don't worry you will get there soon

Hey don't worry your not done growing until your 17-18 years of age!   I'm 12 and I'm a 36a!!! Btw it doesn't matter how big you are it matters about how confident your are and don't forget personality!

For you that said you want to go from a 32a to a 36a well that used to be me a year ago but now I'm a 36a the # has nothing to do with the boob size the number is how big your chest is under the boobs and I hated people telling me to wait so you could always buy a 36a and stuff it very subtly and it will look natural with mabe three sheets of crumbled up to in each side and now I don't even have to stuff
good luck

Mind are 32c I'm slim and 12 and only 5'4"

I don't know mine are ducking a 38B and its hell

There is no general consensus on how big they should be. It is dependent on genetics, how early she developed etc. Everyone develops at different times and at different rates.

I'm 11 and I think I'm a 28A Well the smallest size.
I hate mine coz I breath in and stick my boobs out but I don't mean to and they are too small! For my age!

Hi!!!  I'm 12 and only have 34b but I hate them so much!

Am twelve and am a 36D I don't noe how cause my mom is extremely flat chested

Hey babes I 12 and I'm a 39AA my boobs

I'm 12 and I'm a aa32 how bad is that I need some tips to grow them lol

Hey I'm 12 and I have no boobs at all like a 2 year old you have to help me please. I hate it all my friends have boobs but not me HELP ME!

I am 13 and I am a 36 so for you it will be probably 34

Well I'm 33a but my friends are either a or b in the mids lol ^.^

It all depends.. When I was 12 I was superr flat but now I'm a 36B.... So ppl can have like growth spurts

I am a 32C I am 12 and like 4"11! Don't worry everyone is different! My mom has small boobs but my grandmas r both pretty big! It is all genetics!  I have the biggest boobs out of all the girls in my grade and I am the youngest don't worry!

I think they should at least be at a 36a or a little bigger but my are a 32a and I want them to at least be a 36a I'm 12 and I want them to be bigger. Every girl's in my grade are bigger than my accept for atleast three ppl. I'm desperate for a big chest but we should be happy with what we got and my mom just happend to buy two bathing suits that wont fit me because the tops are too BIG!!!!!!
And I also want a big chest to attract guys.

My size is 36a

My friend has to have at least 36B or 34C but I think its just genetics

I'm 5'3", 85 pounds and a 34a. I'm 12 and a shoe size 7
