I want to calculate the size of Crocus in Fairy Tail. Human head is 13% of the human height, meaning it would be 0.221 Meters.
Photo 1:
Human head = 0.221 Meters = 4 px
0.221 Meters/4 px = 0.05525 Meters per px
Length of arch = 171 px = 9.45 Meters
Photo 2:
Length of Arch (It is the black line, ignore the red one) = 9.45 Meters = 18.68 px
9.45 Meters/18.68 px = 0.506 Meters per px
Interior Circle of Coliseum (Green Line) = 363 px = 183.678 Meters
Length of Statue to Statue (Green+Blue Lines) = 617 px = 312.202 Meters
Photo 3:
Length of Statue to Statue = 312.202 Meters = 94 px
312.202 Meters/94 px = 3.321 Meters per px
Diameter of Crocus = 1615 px = 5363.896 Meters
A = πr^2
A = π(4.3)^2 = 22.6 Km^2
