I have purchased Feral Warwick skin at the last discount. When I select it, Warwick looks bigger to my eye. Is it because of colors or is Warwick actually bigger? Most important of all, if it is bigger am I easier to target?
Short answer: Skins do not affect the hitbox of champions.
There are only 3 hitbox sizes in League of Legends, and skins do not change which hitbox a character uses according to this post.
Kennen is a small hitbox. Ashe uses a medium hitbox. Cho' Gath uses the large hitbox.
Thanks for your post! Gameplay hitboxes actually come in three sizes for all champs, >small, medium, and large, and don't change based on things like animations, the model, >or character facing. We do this so that you and your opponents get a consistent >experience.
Galio's wing's aren't actually making his hitbox larger, though he does have a "large" >size hitbox already. As warmonkey and Oluldan pointed out, this both helps Galio tank >and is appropriate given the size of his character.
Yes, you are both of course correct, Cho'Gath, Nasus, and Renekton's abilities do cause their hitboxes to increase in size.
