How much area does Shoko’s armpits take up?
To begin, I need to establish what the bounds of what constitutes the armpit are!! Which, for this, I’ll be using the second photo as a reference
Now I have a great reference on Shoko with nearly this exact pose!! The issue becomes the fact I can’t see the outlines of her arm thanks to her shirt being baggy
To remedy this, it’s quite simple!! First, her wrist width, which I can definitively see and thus calculate!! Taking into account her wrist is angled, I calculate it to be 5.25 cm in diameter!!
Now this is where AIST, a database I’ve used before, comes in handy!! These measurements were taken on women shorter than Shoko, so I can assume Shoko falls on the high end of the observed results, which puts her at 6.1 cm, for simplicity’s sake!
And for the upper bicep, which I can use the same method to estimate Shoko’s to be roughly 8.5 cm flexed!!
Then, finally, I can use their measurement of the diameter of the body at armpit level!! Really it’s axillary chest circumference, but I can simply find the diameter using that by treating it as a circle!! This comes out to be roughly 26.9 cm!! All this really allows me to do is estimate where the armpit region of Shoko should be so I can approximate the shape of her arm + armpit for other purposes
Now I can overlay the photos and estimate the area of her armpit!! Doing this is the most simple part, since I have all my rulers! For simplicity’s sake I’ll be treating is as an oval!! This gives me my final answer of 70.69 square centimeters!!
It’s worth noting that, since the armpit isn’t flat, this is a low boundary!! It’s likely slightly higher!! As one would expect from Shoko, she’s perfect!!
