Guys, just play the game and see the length outward from a hero using crosshair lengths to determine where you start to miss. It will always be bigger than the crosshair length to the edge of a character’s model–that’s proof enough that the hitboxes are exaggerated to the models of the heroes, meanwhile the devs somewhere said that hanzo’s arrows are on par with genii’s shurikens in terms of size.
If this isn’t enough proof I don’t know what is.
