Let's say I have a comics book page, e.g. Tintin - my book edition is A4 size. And most drawings (frames?) on a page are about 5cm x 5cm or something around it.
I expect that author did not torture himself and he was not drawing those frames so small but they were scaled down to fit A4 sheet after putting in grid.
So what is the original size of such comics drawings? I assume every author goes its own way but I'm asking about typical/average, e.g. is it like every frame is A4 or smaller or bigger.
