First method, direct pixel scaling.
Madara is 41 px and 1.8m tall.
It scales the 46 px green line to 2.01 meters.
Purple line is 6 px and 2.01 meters tall.
Which scales the 20 px yellow line to 6.7 meters.
Nose is 24 px, head is 380 px.
Scaling the head of PS to 106.3 meters.
Head of PS here is 58 px and the full body is 325 px.
Which means that the height of PS is 595 meters tall.
That's the first method, but I'm not satisfied with the result.
The second method is using Angular distance.
Madara is 41 px and 1.8m tall.
It scales the 46 px green line to 2.01 meters.
Purple line is 6 px and 2.01 meters tall.
Which scales the 20 px yellow line to 6.7 meters.
The nose is 9 px and 6.7 meters.
Perfect Susanoo's waist is 218.343765 pixels.
Which scales the waist to 162.6 meters.
Waist is 195 px and 162.6 meters.
Panel height is 1192 px.
2*atan(195/(1192/tan(70/2))) = 13.07 degrees
Angular distance gives 709.71 meters from the ground to the Perfect Susanoo's waist.
From the ground to the waist, it's roughly half it's height. So just multiply it by 2 to get the a close estimate of how tall PS is.
1419.42 meters tall
