@comrade I appreciate the effort, I really do, but you are just flat out wrong. I don't really have the time (or the intention) to go back and forth on this. However, using your own pic you used to scale Pica, we can see that he's clearly a few kilometres tall. I added the explanation text to the image:
This picture shows that Pica's golem was comparable to Flower Hill in height:
Anyway, Pixel scaling is a lot more robust than these guesstimates we are doing. I'm not on board with non rigorous attempts to estimate the golem's size, but your result is clearly and obviously wrong. Pica's calves alone are much taller than 300m (let alone his entire golem).
I may not reply further to this thread. I do not endorse guesstimate scaling, and arguing which of the two of us is more accurate is uninteresting. Rigorous scaling attempts (my multiple people and which have been reviewed) place the golem at 2.7 km tall. Their attempts may be incorrect, but they are much more likely to produce an accurate answer than mere guesstimates. The fact that multiple attempts arrive at the same figure backs it up.
