Hello and welcome to this fine scientific document. Prepare yourself for a lesson in: Bra sizes, Boob Sizes, fruit(?), basic mathematics??!!, physics, and biology.
This is an intro course to the study of Tits and how the compare to each other. As well as the physics involved in bashing them with other boobs, fists, objects, etc.
There are a few notable topics for us to cover but I've noticed that there are some myths we should clear up first:
1. Cup size tells you someone's size- This is a big fat lie. First of all US and UK sizes are different. Second band size matters. The cup size is relevant to the distance around bust.
2. Size can be effectively judge from a photo- Its relative. If we are talking about a girl who is 5'8" 150 pounds and rocking a 42G rack. That photo could very well look like she has an average set of boobs when frankly she is a tall hefty darlin and the size around her bust is large in comparison to her already big breasts. Versus a girl with a 30E chest who is going to have a lot of boob on a small torso but, her chest doesn't have the same volume even if it LOOKS like shes substantially larger.
3. Bigger boobs always win- This is also highly relative. Suffice to say bigger breasts mean you have more mass to swing around. Which for the nerds out there F=M*a
Basically if you increase mass (M) you can increase your overall force. So getting clocked by a bigger tit will impart more force at the same acceleration as a smaller tit. In addition to this there are myriad other factors we will cover in the breast composition section.
Bra Size (alternate title: Getting beat by an E when you're an H)
First an illustration.

This is Tanya Danielle she is (also hot) a 36E.
So who do you think is bigger from the images and from the cup size and band size. (UK measurements so I'm not tricking you).
I'll let you consider your answer for a minute.
....
TIMES UP!
So you've probably guessed it's a trick question. Both of the girls are packing approximately 1000cc of boob. Note that Tanya is "enhanced" so this changes the physics a bit however in terms of actual volume they are the same size. This is a vocab term known as a Sister size. A sister size is a bra size that has a comparable volume but the band is a different length.
There will be a test.
So now we have to wade into the world of Bra sizes. For simplicity I've defaulted to UK sizes for everything. There are comparison charts for converting bra size but it seems the most straightforward to me to size UK because the US has an obsession with Ds for some reason.
https://www.herroom.com/bra-size-conversion-chart,1355,30.html (https://www.herroom.com/bra-size-conversion-chart,1355,30.html)
Note band size is the same between the two.
And here is your sister sizes/Volume chart.
https://www.laurengreenbergmd.com/breast/what-is-the-volume-in-cc-of-a-cup-size/
(https://www.laurengreenbergmd.com/breast/what-is-the-volume-in-cc-of-a-cup-size/)
So how does this all matter? Well I've seen more than my share of girls and I mean girls start in on a conversation about breast size and how they out class another girl from pictures when there is actually either A) nearly no difference or B) a huge disparity in size often in the favor of the girl with a "smaller" cup size but a huge band size difference. Usually this is the girl being accused of lying about her size.
Keep in mind this is all academic we are on the damn internet. An A cup could crush my titties if the story went that way. Makes no sense but we aren't actually smashing each others boobs so take this with a grain of salt.
Breast composition (alternate title: Those are totally fake)
A quick biology lesson for perspective: Boobs are usually made up of a few types of tissue.
Fat- This is most of your boob
Breast tissue or fibrous tissue- most of the rest of your boob.
Glandular tissue- milk glands, etc.
Skin and nerves- exactly what it sounds like
Your breast sits on muscle over bone. This is relevant for a few reasons. If you've ever played around with exercising you probably know that building up the muscle under your breasts makes them look more pronounced. It can also decrease their size because when you exercise your body reduces your fat stores and surprise surprise your boobs are a bunch of fat.
The fibrous tissue also matters because it's part of what gives your chest firmness. More tissue less fat. More firm less squish.
This is further compounded by the nerves in the skin of your breast. If you've ever taken a hit to the chest you know it hurts like hell. There are extensive nerves in the skin and the tissue of the breast that are responsible for this. Higher the density of nerves the more sensation. Which leads to your ability to take punishment in a fight.
Still with me?
Okay now we add in enhancements. This dramatically changes the composition of the boob. Think of these like the Terminator in a titfight. Squishy outside and potentially hard unfeeling tit crushing on the inside. In addition the nature of the implant and the surgery involved have wildly varying effects including things like loss of particular sensations such as pleasure or pain due to nerves that were cut. The point is that when you include implants and enhancements you end up with a rather wild range of results in your titfighting experience.
For a practical standpoint this is again academic. For cybering purposes I dont really care if you are enhanced or not it doesn't change how I write unless that's specifically part of the cyber.
Comparing Breasts (alternate title: Do my watermelons match up with her cantaloupes?)
TLDR: It doesn't matter. If you really care keep reading. If you're a writer and you want to titfight with another hottie. No one cares just use general terms, if you know you're bigger or that she is bigger just write it like that. Same goes for firmness vs squish. Enhanced vs natural. This is by its nature an academic exercise so only use it if you REALLY care to want to be realistic.
The easiest way to put this is simple:
What is your cup and band size?
What is hers?
Are they a sister size?
Are they within a reasonable volume of one another (convert to CCs from the size)?
Make sure you're both using the same size guide, American vs UK VS EU is different.
Are there any other important considerations? Enhanced breasts, particularly pert or firm breasts on one side, lack of sensation from a surgery, etc.
Keep in mind that photos can be deceptive. If your opponent is a tiny girl with a low weight and a big cup size. Check her band. Her boobs maybe relatively big compared to her torso so she looks like a monster in her photos but in reality she is actually smaller.
Thanks! Hope it wasnt too boring of a read.

Tito-what now?
I'm waiting for the more advanced class!
Like Trigonometry but with...tits...
You say that but when you have to explain to a girl size difference between your chest and theirs is like a standard package of bacon you begin to realize the masses require education.
...haven't the faintest what I'm going to write going forward. It's probably just a physiology of boobs course with case studies in being punched in the chest/titfighting.

They said there wouldn't be math!
And FCF has a new queen. An account with pictures of a naturally beautiful woman who isn't caked in makeup, who has a phenomenal real woman's body, and is here typing up the kind of thing that gets me hotter than 99% of the supposedly erotic stories here.
I bow and await your orders.
I feel like the different size guides for US, UK and EU need to be stressed. I mix them up frequently and when people throw their DDDs at me when they don't look that much bigger just confuses me.
Anyway, fun read. If you need volunteers for presentations and whatnot... *winks and points thumb at self*

Oh my goodness the size guide difference makes my head spin because DDD is ONLY A THING IN AMERICAN SIZES.
Presentations. Huh. Everyone this is Jana a lovely specimine of big boobed goodness. *whispers* "Tell them all how big you are lets see if they can convert that to CCs"

Yes please.
This has been exceptionally informative for my Titfight Sim. I don't know how I'd implement any of it, and if I did I'd have to grossly overhaul the rudimentary calculations that I'm currently using, but it's been a wonderful read at the very least. I'd like to convert everything to CC and differentiate into cup size from there, but with over 400 women already in the roster, that's a task too steep for me to tackle.
I am horrible with math but this was a great read!

Glad you liked it!
Wonderful read! I'm sure I'll find it very helpful in the future! Thanks so much!
Good to see that people are still referencing this. I'd like to incorporate it into my Tit-Fight Sim, but I don't know which measuring system should be standard (I'm leaning towards UK due to them using a single letter system). There's also having to figure out what system stars sizes are listed as (American's would use US, and Brit's UK, but what about someone from Europe? Or upper Asia? Or any of Asia for that matter?)
Thank you for trying to enlighten all the cyber masses how basic body size affects tit size!
As a woman who lives in the B/C range, but works out a ton and has a thick chest, it gets very tiresome constantly explaining to other women that just because they outsize me by two cup sizes doesn't mean their tits are bigger when we line up against each other. Now I'm simply going to link to this and tell them to talk to me when they understand the basics of comparing bodies.

Sooooo all of those places have their own Bra sizes ^^" Europe is actually it's own sizing guide coming in third as the most popular. You may just have to fudge a little. I find UK the best personally despite being from the US.

I'm glad I could be of service. Quite honestly it has always amazed me that the vast majority of people ignore the number after the cup size. Even in real life I see this happen all the time.
Happy new year! And yes I will never understand why people ignore the number after the cup size. It's kind of important lol
Basically for every major area of sale: US, UK, EU, Australia, Asia
Wow, cool. Finally gospel truth about chest physics.
