As usual, peer review open!!!

Okay, as a mechanical engineering college student, I again used my drafting skills to sketch and create a size chart for Trissy. If you wish to read my process, go ahead and let your eyes gorge on what pure boredom can drive a man to do.

Original post got absolutely obliterated in the main server lmfao

====================================================================================

There is no official height for Trissy, but according to the Donghua, Tris is 175 cm. But after drinking the Witch Potion her height drastically changed, throwing my calculations off by a lot. So I had to redo a looooot of work because of that mishap. There's nothing about her height on the wiki or obscure Q&As from CF himself, so what the hell did I do?

Welp, since I had For's official height and Audrey's official height, I just pixel matched it to Trissy's official portrait to get the size right, used For's calculated height reference, all to finally start the process. It does leave a bad taste in my mouth knowing that there's already a point of failure, something that I take very seriously and something that I try to minimize as much as possible.

Anyways, I used a solid reference of 21.52cm from Fors to roughly gauge Trissy's overall height which surprised me when I saw that she's only 162cm tall. (162.07cm if you wanna be very specific)

Now by referencing small horizontal slices (manual integration) to the lengths of Trissy's head (x,y) I managed to get 18.825cm for her head's vertical length, and 10.66cm for her head's horizontal length.

Now let's move on to the next picture.

Since we're only given her head's height in the frame, I used it as reference to get her sideboob's horizontal length from the armpit and from the ribcage. (Remember, those exist. C'mon, it's anatomy... it's very important.)

By using halves upon halves of 18.825cm(x) next to her sideboob's horizontal length, I managed to get the values that match.

The calculation I then used is,

9.1425 + 1/3(4.7062) = 7.5737cm for her sideboob's x length from the ribcage.

By adding the manually deduced value of 4.7062 to 7.5737, we have 12.2799cm for her sideboob's x length from the armpit.

As for her boob's y length, I used 18.825 as the base because of it being the only reference point available, then I got to work by measuring her boob's height and mapping it on a copied y "ruler" of sorts, and saw that roughly 25% is removed from 18.825 to get it.

So the basic formula is just 18.825 - 25%, or to be sure, I used the other method of,

50%(18.825) + 25%(18.825) = 13.8487cm for her boob's y length.

13.8487cm will be important for the next frame as her head isn't visible.

Now for the methods that I employed. I basically traced the most likely spots her arms are located (or else it'll look uncanny, let's be real) and marked her boob's already established height of 13.8487cm to then use as reference to the drawn horizontal (z) length of her boobs.

0.8655 = 1/16(13.8487)

So now for the formula since I've observed the estimated locations of each boob.

1/2(13.8487) + 3(0.8655) = 9.52073cm front view horizontal length.

=======================================================================================================

TLDR!!!!

Sideboob length from ribcage = 7.5737cm

Sideboob length from armpit = 12.2799cm

Boob's vertical length = 13.8487cm

Horizontal front boob length (individually) = 9.52073cm (19.04146cm combined)

Boob weight = roughly 600-700 grams (very educated guess as usual)

Cup Size is D

Calculating the milk production of Fors Wall per day.

Peer review open!!!

Just so you know, I literally got hit by a reckless cyclist and my knee's currently out of commission, but I'm still making this anyway.

Also, important note: I am not the smartest person to do this (I'm a mech eng. student ffs), I'm just following the procedure (and skipping a lot of them) that was given to me by my professor. My professor is unknowingly giving me answers to what they think are academic inquiries, when they're being used to calculate lactation of a novel character.

Based on what I spent reading this research. I'm sorry to everyone cited above who used their time for the sake of science, and here I am using it for this lmao.

If we're trying to place Fors on a broad baseline using what the current research can actually support, I would come away more reassured than concerned. There are no obvious major risk factors in Fors’ assumed history that would make me immediately suspect that she is at a high risk of inadequate milk production, although there are a few lifestyle factors worth keeping in mind. I also want to emphasize that this is not a prediction of how much milk Fors can or will produce, it’s more of an assessment, an averaged of averages if you will, of whether anything described in the novel stands out as a known risk factor.

Starting with Fors’ assumed puberty and breast development.

If we're basing our assumptions that she had a typical breast development beginning around age 11, it falls within the expected range of 8-13.

Here's the cool part where I can base my size calculations. Such a size usually means that the growth isn't gradual, but rather something that went through a growth spurt. Don't look at me, I'm just the messenger lmfao.

From a developmental standpoint, nothing here suggests abnormal breast development or insufficient glandular tissue. That's good.

Fors’ breast anatomy is also generally reassuring. My calculations shows that her breasts as being only about 1.5 cm apart (when I accounted for the mf’ing sternal gap. BOW DOWN TO MY METICULOUSNESS), which I recently learned is actually much closer together than the spacing that has sometimes been reported in studies investigating breast hypoplasia. They are also symmetrical and characteristically round rather than tubular. While physical appearance alone can never determine the capacity to produce milk, the particular anatomical features that my calcs show do not resemble the markers that researchers have associated with a higher likelihood of insufficient glandular tissue. In short, based solely on anatomy, it's all good.

For’s hormonal history is another shaky aspect of this study, so everything will be averaged. Regular menstrual cycles suggest that her reproductive hormones are functioning in a fairly typical way, and from what we know, she doesn't seem to have a history of thyroid disease, diabetes, polycystic ovary syndrome, elevated prolactin, or other endocrine disorders. Since these conditions are among the more established medical causes of reduced milk supply, not having them is good for production. That’s what I read, okay? Don't blame me for this.

Anyways, her medical and surgical history is similarly favorable if we're talking about Sequence 9 Fors. Because she has never undergone breast surgery or experienced significant chest trauma, there is no obvious reason to suspect damage to the nerves or milk ducts that are important for successful breastfeeding.

Now as for her family history, it's perhaps one of the most discouraging parts of this study, because uh... I don't know about them lol. I tried skimming through the novel again, but I don't think they were ever mentioned?

Anyways, back to the averages. Let's say Fors’ mother successfully breastfed her, and she doesn't have unusually low milk production among her female relatives. But hey, family history alone cannot predict raw milk supply, but it is still a considered piece of background information because it would suggest no apparent pattern of any inherited breast developmental problems.

The one area that stands out most is Fors’ general health and lifestyle rather than her anatomy or hormones. At 165 cm and 44.5 kg (CF is the source btw), Fors’ body mass index is around 16.3, which is considered underweight. Being underweight does not automatically mean she'll have difficulty breastfeeding.

Why? From what I read, many underweight women breastfeed successfully. But, but, but, but…….. it could also mean she has smaller energy reserves normally. Since producing breast milk requires additional calories every day, maintaining adequate nutrition during pregnancy and especially while breastfeeding would become more important for Fors than it might for someone with larger energy stores.

Anyways, I know you want me to consider the effects of Mr. Door on Fors, but they are unlikely to reduce her future ability to produce milk by themselves. However, the combination of immense pain, disrupted sleep, smoking, and alcohol use could make breastfeeding more challenging in practical ways. Poor sleep and stress usually have a greater effect on how milk is released than on how much milk is produced, while nicotine can have a modest negative effect on supply. Fortunately, the level of smoking described in the novel, it's quite occasional and more of a remedy rather than heavy, so it is less concerning than daily use.

Plus, since she no longer suffers from them, I ruled them out.

Now on Fors’ lifestyle overall, the descriptions don't raise major red flags. Her regular physical activities (despite somewhat being sedentary at times) is perfectly compatible with breastfeeding, and a stress level of that (another estimate, sorry) is something many new parents experience. Irregular sleep is probably the factor that would affect how she'd feel day to day more than it would directly affect her milk production. One thing worth noting is that newborns tend to make sleep even more fragmented, so if Fors is already someone who is sensitive to poor sleep, that may influence how exhausting the breastfeeding experience feels even if her milk supply itself is adequate.

====================================================

TLDR!!!!! (1/2)

Putting everything together, if I were estimating Fors’ baseline based only on the information we've been given by the novel, I would probably summarize it like this:

Risk of insufficient glandular tissue is low.

Risk of hormone-related low milk supply is also low.

Risk from breast anatomy? Yeah, it's not much. So negligible.

But her lifestyle factors that could modestly interfere are present, but generally manageable. (Especially during later chapters in book 1)

ANYWAYS,

Here's a nutritional factor to keep an eye on.

The biggest unknown is also the one that no questionnaire can answer from the research papers I read is how Fors’ breasts would respond during pregnancy.

Pregnancy itself causes the glandular tissue to grow dramatically. That response, along with how effectively her baby nurses after birth, ends up being much more predictive than anything we can assess years beforehand.

Also, size does not affect milk production, study female biology first before saying BS like that lmao.

.

.

TLDR AGAIN!!!!! (2/2)

So assuming that everything is within the safe zones combined with what we know in the novel, and we say that she's postpartum for 3 months and the baby drinks adequately, here are rhe results.

Typical milk production: 700-900 mL/day

Lower end of normal: about 600-700 mL/day

Higher end of normal: 900-1,200 mL/day (she may naturally produce even more)

Read this if you want to see an engineering student at work.

Peer review open!

================================================

Anyways, how did I get their dimensions?

Simple, by first acquiring official height info about Fors Wall, I managed to get the value of 165 cm. Now that's how I got to work. I first took the official image of Fors with a full body shot.

I drew a line accounting for perspective and the top of her head without the hat then halved it to get 82.5 cm.

With that being set as the midpoint, I grabbed the measurement of her head from the calvaria (or the crown, basically the topmost area) to her chin. I carefully duplicated the empty value to the midpoint and measured that:

3h + 1/2h + 1/3(1/2h) = 82.5

Then,

3.833333h = 82.5, h = 82.5/3.833333

Which got us her head's length from top to chin as, 21.52 cm. As for the width of her face from cheekbone to cheekbone, the process I used is this below, to get 1/2h + (1/3(1/2(1/4h) but simplified.

1/2(0.25h) = 0.125h, 1/2(1/3 × 0.25h) = 1/24(h) = 0.04167h

Then,

0.25h - 0.125h - 0.04167h = approx 7/12h = h is now 21.52 cm

Then (7/12)(21.52) to get 12.55 cm for her head width.

Now, I went to measure the extrusion of her boobs from the side view. Since we know her head's top to chin length is 21.5 cm, I just did this.

1/4(21.5) = 5.375

10.75 + 1/2(5.375) = 13.4375 cm (16.375 if starting from armpit)

Yes, that's right. From the ribcage to the outmost extrusion of Fors' boobs, the distance is around 13.4375 cm.

Now onto the size of each individual boob when viewed from the front.

We'll start with the head's cheekbone to cheekbone distance value that we have, which is 12.55 cm.

Now, you basically just have to do,

2(12.55) + 1/16(12.55) to get 26.66875 cm. (Sternal gap accounted for)

Divide by two to get the length of an individual boob, and you'll get 13.334375 cm.

As for height, it's kinda just 13cm as well, give or take.

=======================================================

TLDR:

Boobs from side: 13.4375 cm (16.375 cm if starting from armpit) Boob height is similar to side dimension, don't worry. It's quite circular anyways.

Boobs from the front: 26.66875 cm (13.334375 cm for each one)

Weight for an individual boob: 680.389 grams. (Very educated guess)

D cups are a safe estimate.

Personally, I like shooting down the one that gave me a headache once I learned how to dodge em.
