Different Boob Shapes, Types & Sizes

32A, 34B, 34C & 34DD Breasts

Have you ever wondered if your boobs were ‘normal’? Magazines and lingerie adverts would have you believe that breasts should, and often do, look a certain way. But the truth is that there’s a whole, wonderful variety of boob types out there!

It’s not just to do with size – breasts also come in plenty of different shapes. But first, we will look at size variation, and explain just what those cup letters really mean.

What is cup size?

Your cup size is defined by the difference in the measurements below and around your bust. It only accounts for how far out your boobs stick, not how wide they are – in other words, two sets of B cups can actually be quite different in size.

Here’s how to calculate your cup size:

First, measure yourself using a flexible tape measure. Your underbust measurement is taken directly below your breasts, while your overbust measurement is taken around the fullest part of your breasts, usually across the nipples. The tape must be horizontal all the way around the body for an accurate measurement.

A cup = 1” difference between underbust and overbust

B cup = 2” difference between underbust and overbust

C cup = 3” difference between underbust and overbust

D cup = 4” difference between underbust and overbust

DD/E cup = 5” difference between underbust and overbust

DDD/F cup = 6” difference between underbust and overbust

DDDD/G cup = 7” difference between underbust and overbust

H cup = 8” difference between underbust and overbust

Note: the cup sizes listed above are US sizes. For international conversions (and to see cup sizes beyond a US H or below a US A) take a look at our bra size calculator page.

What do different boob sizes look like?

When it comes to understanding breast sizes, it’s important to know what both the number and letter parts of a bra size mean. As explained above, the letter, or cup size, is how far out the boobs protrude from the body.

The number on the other hand is how large the ribcage is, and is therefore not an indication of breast size, but rather of body size. Unlike cup sizes which go up by 1” differences, band sizes go up in lots of 2” because, in US and UK sizing at least, they are always an even number.

What do 32A breasts look like?

A person who is a 32A has a roughly 28” ribcage (because many lingerie brands manufacture their bands to fit 4” smaller than the number given on the label), and breasts that protrude only very slightly from the torso. You can view a real-life example of a person modeling a 32A bra in this blog post.

What do 34B breasts look like?

A person who wears a 34B bra has a roughly 30” ribcage (again, 4” smaller than the number on the bra, and 2” or one band size larger than the 32A wearer), and breasts that protrude slightly more from the torso than an A cup would. You can view a real-life example of a person wearing a 34B bra in this blog post.

What do 34C breasts look like?

A person who measures a 34C has a roughly 30” ribcage, but this time has breasts that protrude yet more from the torso than on a B cup. To view some real-life examples of 34C bras being worn, take a look at this page on Bratabase.

What do 34DD breasts look like?

A person who is a 34DD would, once again, have a roughly 30” ribcage, plus breasts that protrude significantly more from the torso than on a C cup, since this is a jump of two cup sizes. To view some real-life photos of people wearing a 34DD bra, take a look at this page on Bratabase.

bra cup size weight

How much do different breast sizes weigh?

This is a tricky question to answer, due to the fact that a cup letter is meaningless without an accompanying band number. Most ‘breast weight’ charts only take into account cup size, but not all A cups (or B cups, or C cups…) are equal. As well as a 32A person having a smaller ribcage than a 34A person, they also have smaller boobs.

That’s because, as we explained at the start of this article, the overbust measurement doesn’t account for breast width. Naturally, the boobs of someone with a very wide torso (who therefore wears a large band size) are going to be wider than someone with a much smaller torso, even if both persons’ breasts protrude the same amount. The person wearing the larger band size would have more breast tissue overall. 

In fact, there’s a rule in bra fitting called ‘sister sizing’. This indicates that when you go up one band size you should also go down one cup size, and vice versa, to maintain the same overall volume of space in the cup. So if a 32B fits you in the cups but the band is loose, you should move to a 30C. The 30B’s cups will have less space in them than the 32B’s. 

That said, let’s look at some of the data that does exist for breast weights. The numbers below are all based on information from retailer Hourglass Lingerie.

How much do A cup breasts weigh?

32A = roughly 0.5lb or 226g per breast

34A = roughly 0.6lb or 272g per breast

36A = roughly 0.7lb or 317g per breast

38A = roughly 0.9lb or 408g per breast

How much do C cup breasts weigh?

32C = roughly 0.7lb or 317g per breast 

34C = roughly 0.9lb or 408g per breast

36C = roughly 1.2lb or 544g per breast

38C = roughly 1.5lb or 680g per breast

How much do DD breasts weigh?

32DD = roughly 1.2lb or 544g per breast

34DD = roughly 1.5lb or 680g per breast

36DD = roughly 1.7lb or 771g per breast

38DD = roughly 2.0lb or 907g per breast

Did you notice how some of the figures overlap – for example, 36A breasts and 32C breasts weigh the same? That’s down to the sister sizing thing we just explained. Sister sizing up from a 32C gives you a 34B (remember, when you go up one band size you go down one cup size), and then sister sizing up again gives you a 36A. While 32C and 36A breasts may not be the same shape, they do both contain the same amount of breast tissue.

different boob shapes

Different types of breast shapes

Boobs come in an endless list of shape varieties, so we won’t cover all of them. But let’s take a look at some of the more common boob shapes:

Full on bottom – this breast shape has more tissue below the nipple than above it. You’re more likely to have boobs this shape the older you get, since we tend to lose upper fullness over time. People with this breast shape may find that even when they fill out the bottom of a bra cup, the top edge gapes, especially in molded bras.

Full on top – conversely, this breast shape has more tissue above the nipple than below it, and hence the nipple will point somewhat downwards. People with this breast shape may struggle with ‘overspill’, where the top edge of the cup cuts in because their breast tissue is so full here. 

Round – this breast shape could also be called ‘evenly full’, because there is the same amount of breast tissue above and below the nipple. Generally seen as a desirable look, it’s often the boob shape that people end up with after cosmetic breast surgery.

Pendulous – this is a breast shape that hangs down, with the bulk of the breast tissue being below the crease where the breast joins to the torso. This is a form of full-on-bottom breasts, since the top part of the breast is very flat/shallow. Many large breasts are pendulous, due to gravity!

Close-set – this shape is one where the breasts are very close together or even touching. People with this breast type find it very easy to get cleavage in a bra, and may even be able to wedge items such as a pen between their boobs without them falling!

Wide-set – this shape is opposite to the one above, i.e. the breasts are far apart. Boobs are generally regarded as being wide-set if you can fit three fingers flat between them. People with this breast shape will likely struggle to create a cleavage line.

Splayed – also known as an ‘East West’ shape, this breast shape is where the right breast points to the right, and the left breast points to the left. People with this breast shape may find that bra cups gape only at the centre, by the sternum, because the majority of their breast tissue is towards the sides of their body.

Asymmetric – as the name suggests, this breast shape describes boobs that are slightly different in one way. Perhaps one’s a little larger, or they are different shapes. It’s actually incredibly common; most people’s boobs are asymmetric in some subtle way, but for some people, the difference is more noticeable.

Note that it’s possible to have more than one of the above boob shapes! For example, your breasts could be close-set, full-on-bottom, and asymmetrical.

how to make your boobs look bigger

How to make your breasts look bigger

Many of us wouldn’t mind being a cup size or two larger. But in many cases, we don’t want it enough to go through with breast enlargement surgery. Luckily, whatever your bra size or natural breast shape, there are some tricks you can use to make your boobs temporarily appear bigger.

Padded and push-up bras – padded bras are exactly what the name suggests: bras with thickly-lined cups to add extra volume. Push-up bras are a specific type of padded bra, which have a thicker layer of padding at the base of the cup than higher up. This way, your breast sits on top of the padding and gets lifted up, for a rounder, more full-on-top shape.

Padded inserts – these function in exactly the same way as push-up padding, the only difference being that these are standalone pads which you buy separately and can pop inside any bra you choose. Be warned though, unless your bra has ‘pad pockets’ inside to hold them, they’ll fall straight out when you take it off!

Boob tape – this is a special type of skin-friendly tape with maximum sticking power. It lifts your boobs up (you essentially hold they where you want them, then apply the tape to keep them there) which makes them appear perkier and often bigger. 

Makeup – if you’re good at contouring your face, why not contour your décolletage? It’s important to keep the look subtle, so it’s not obvious you have makeup all over your chest, but a few carefully-placed shadows and highlights can make your breasts seem like they’re fuller.

Get a bra fitting – last but not least, be sure you’re wearing the correct bra size. A loose band, for example, isn’t able to properly support the weight of your breasts and they’ll sink lower on your chest. A well-fitting bra has a firm band that’s able to keep your boobs lifted high, plus cups adequately deep for your breast size and shape (which will allow them to stick out more than before, if you were previously wearing too-shallow cups).

Why are breasts called boobs?

A fun question to finish! There are so many monikers for what we have on our chests, but ‘boobs’ is by far the most common one. So where did this word originate? 

It could actually be one of two places. It is known that the original word was ‘booby’, which was shortened to ‘boob’ in the 1920s. But linguists are split over where ‘booby’ came from. Most likely, it evolved from the even older English word ‘bubby’, which also meant a woman’s breast. But it’s also possible than ‘booby’ is simply an Anglicization of the German word ‘bübbi’, which means teat (the nipple of a female mammal) and sounds the same.

But whatever you call them and whatever size and shape yours are, let’s celebrate that all of us have unique breasts – it’s just one more thing that makes you you!
