  • Bigger boobs would be the 28DD

    Bigger body would be the 34B

    However, the cup size does differ with the body size... Chart does not go down to a 28 but you get the idea.

    Let's try again! Which size is bigger, 28DD or 34B?

    • 28DD and 34B both have the same volume

    • Which is what I was saying by the chart. However, I think the 28DD would stand out more.

    • Yep I get you! Well done, you have a better understanding of it than most women tbh! Nah 28DD still looks very small though

  • I know it's a trick question, but don't know the answer. It's either that they are the same or that the b is bigger.

  • I don't really believe in the whole sister sizing thing, maybe it just doesn't work for my size. I assume that this is what you are talking about?

    • Yep, 28DD and 34B are sister sizes! :) Maybe I can help you, what size are you and what sister size have you tried?

    • I've tried all I could according to a chart I've found. None fit well at all 😂

    • Okay girl, I know the struggle! I've been there. Try this calculator!! https://www.abrathatfits.org/calculator.php

  • That depends, are you talking about the overall size of the chest area, or the breasts specifically?

    • Well tell me what you think for each of those options

    • For the overall chest area, I would say the 34B, only because the number is the circumference around your upper torso, therefore that would be larger in generality, but if it is the breasts specifically, the 28DD, because the letter is the measured cup size, and the further along with the alphabet you go the larger the cupsize, hence the larger the breast.

    • I see where you're coming from and thank you for your guess! But 28DD and 34B actually hold the exact same cup volume!

  • 28DD is the same relative size as 30D, 32C, and 34B. Only difference is, it's on a smaller sized woman, so they'll look bigger in proportion to her body, and the 34B will look tiny on a bigger woman.

    • You're right except for one thing, they pretty much look the same size too, the only visible difference will be in the larger woman's frame. 28DD is a very small size

  • Nobody cares which size is bigger on paper.

    Those 28 DDs are on a person with a much thinner torso, which means most of those boobs are going to made up of their own volume and look much more appealing to most men overall.

    A band size of 34 is chunky, that's not a fit woman by any means, and her boobs are mostly going to be the result of her excess fat.

    Men don't care about your mathematics, and will say the DDs are way more appealing.
    I guarantee it.

    • The bigger cup is ALWAYS better because it represents the difference between the chest and band size. The bigger the difference, the bigger the boobs in comparison to the rest of the body. Nobody cares that your chunky, flat Bs are "same in volume" as someone's DDs, when all of you is chunky.

    • Nope, 28DD and 34B hold the exact same cup volume. Some of what you're saying makes sense, you have a better understanding than a lot of people here!

    • They do, but they are on a person of completely different sizes. And they are not going to look the same visually.

  • I would hazard a guess 28dd

  • 28DD as the sizes go up from A, B, C, D, DD, E, EE etc...

    • Nope! A, B, C, D, DD etc aren't bra sizes, unless there's a number in front of them (the band size). Band size is very important. An 'E cup' can look different sizes depending on the band size its on. For example, 26E is a small size. A 32E is an average size. A 40E is a large size. 28DD and 34B carry the exact same cup volume! Neither is bigger.

    • I stand corrected :) and i have to admit in all these years i had never actually known that.. :) thanks :)

    • You're welcome! Some men have argued with me about it, lol!

  • The question is deceiving. 28DD will almost always look bigger which is really what matters to most men and even some women.

    • Nope, 28DD and 34B hold the exact same cup volume and will both look like small sizes.

    • Both should look the same, but that isn't how reality works. I'm guessing you are either a guy or a lady who is mad about her bra size. Otherwise there is no reason to be anonymous for this question

    • A properly fitted 28DD and 34B look very similar, the only thing that will appear different is the women's frames. I'm a girl and I'm not sure what you mean by 'mad about by bra size' but I am mad about the societal misconceptions about bra sizes which cause so many women to wear the wrong size. I used to wear the wrong size thanks to various stores including Victoria's Secret sizing me incorrectly. I now wear the right size - 28DD - a size that I never thought I would be because everyone thinks DD's are large.

  • there roughly the same size volume wise. however the 34b might be better health wise. since she wouldn't be to thin or to thick either. also more likely to have the upper body strength to deal with the weight of her breasts.

    • According to the BMI I’m right in the middle of my “normal” weight. My band size is 28. I wore a 34 when I was overweight. That doesn’t necessarily mean that everyone with 34 is overweight of course, but I didn’t think it’s fair to say that someone with a 34 is healthier than someone with 28.

    • I mean height and weight do play a role overall.

    • either way it is rare for a girl to drop 6 inches in her band size without also dropping a few cup sizes. so you likely have good genetics which often you larger breasts.

  • Thought they were the same size

    • They are different sizes but hold the exact same cup volume :)

    • Right, you asked about size and I answered the same

  • So... 34B is the same volume as 28DD, but 28DD will appear bigger?

    • Yep, same volume. 28DD won't really appear bigger though, no.

    • But if it's the same volume on a smaller ribcage, they'd have to, right? The mass would be more concentrated.

    • I mean, it might appear SLIGHTLY bigger but it wouldn't be a noticeable difference at all! 28DD is a very small size

  • I can't claim to know for sure, but from the way you're phrasing the question, I'm inclined to believe there's no difference between them if you're talking about what they say about the size of ones boobs.

    • Well done!

  • DD of course, that's the cup size, but overbust might be the same,

    • Nope! The 28DD and 34B hold the exact same cup volume :)

    • Interesting, I'd love to know how, if you don't mind explaining,,,

    • It's called sister sizing, if you want to look it up! :) 26E, 28DD, 30D, 32C, 34B, 36A all hold the same cup volume.

  • 28DD

    • Nope, 28DD and 34B both carry the same cup volume

    • Really? Wow you just taught be something but how can that be

    • So basically, people look at sizes like 28DD, 34DD etc and think 'it's DD so it must be big' but cup sizes mean literally nothing without band size! 28DD is a small size, 34DD is an average size, 40DD is a large size. 28DD and 34B are sister sizes, so they carry the same cup volume.

  • 28DD

    • Nope!

    • Confusing lol

    • Basically 28DD and 34B hold the exact same cup volume because they are sister sizes :) 26E, 28DD, 30D, 32C, 34B and 36A are all sister sizes so they all have the same volume (but on different band sizes ofc)

  • Both the same volume!

    • Well done!

  • 28DD

    • Nope

    • Yesterday I and that girl explain to you. 28 or 34 your rib cage measure not your tits. Also Cup A B C D E F are your tits measure 28D tits bigger then 34B

    • Yes, and I tried to explain to you and that girl that you were both wrong.

      Yes, 28 and 34 are band sizes, correct.

      But 28DD and 34B hold the exact same cup volume as they are sister sizes. 26E, 28DD, 30D, 32C, 34B and 36A are all sister sizes which mean they all hold the same cup volume - 390cc. See this chart: Let's try again! Which size is bigger, 28DD or 34B?

  • Double ds

    • Nope, 28DD and 34B carry the exact same cup volume

  • No idea, these numbers mean nothing.

    • The numbers mean everything!

    • To girls only. Also you can have a 28DD or 34B or whatever that look like amazing boobs, and 28DD or 34B that look like saggy potato bags. These numbers mean nothing.

  • Same size. (Won't get fooled twice)

    • Haha, clever! :)

    • LOL :)

  • the actual boob, the DD is bigger

    • Incorrect, they both hold the exact same cup volume :)

    • then why is a DD boob bigger than a B, i am not including the chest cavity

    • 'DD boobs' aren't bigger than 'B' necessarily - they CAN be - but it depends on the band size. Band size is extremely important. DD and B on their own aren't sizes. They can appear all different sizes depending on the band sizes. To explain this further, I wear a 28DD and I have very small boobs. People who wear 34DD have average sized boobs. People who wear 40DD have large boobs. Band size is so important!
