so remember that weird titan that appeared in a portal for saitama and instakill, or whatever was his name? Let's find his size.
no idea how to put the images one by one anymore.
First image
saitama's height = 1.76 meters = 825 PX
Saitama's head width = 90 PX = 18.54 cm
Second image
Saitama's head width = 18.54 cm = 15 PX
Portal's height (where the light goes, not the dark part) = 98 PX = 1.21 meters
Third image
Portal's light height = 1.21 meters = 8 PX
Titan's head lenght = 445 PX = 67.03 meters
Head to body ratio is between 1:6.5 and 1:8, it's body seems muscular and well built so i'll use 1:8 (not much of a difference and he is theorized to be god)
67.03 x 8 = 536.24 meters tall, nearly twice as tall as beefcake's canon height.
Average human head lenght = 19.7 cm
Ratio between human and titan head = 340.25x
Average human height = 1.7 m
Titan height = 1.7 x 340.25 = 578.425 meters tall, over twice as tall as canon beefcake.
