@namtif I had a feeling that their heights would end up being the next possible question from my post lol!
A while ago @mlscience did an incredible job at calculating Chat Noir’s height from the dimensions of the Mona Lisa! Their use of math is way beyond my abilities or comprehension, but I can try my best at estimating an approximate scale for how tall they could be. Just remember, I’m probably not going to be very accurate. ^_^
It took me a bit to find some decent images that showed his full body with a open hand for scale. Thankfully for the wonderful pictures provided by @officialmiraculousladybug I got this excellent character model reference:
I was able to mark the length of his hand, and the number of those that would fit within his height. As you can see he is about 9 hands high
(insert horse jokes haha)
But just to be sure, and have a reference for Marinette as well, I applied the same measurement to another image:
Again I got close to about 9 hand lengths in his height. So if according to my previous estimate, Adrien’s hands are about 20cm long, then that is 20 x 9 = 180cm or roughly 5ft 10in. Marinette’s is about 8 hand lengths, which would be 20 x 8 = 160cm or 5ft 3in. Giving a few centimeters for a margin for error, they could both be slightly taller or shorter than my measurements.
