I think Lee means if the size of the sprite is very big in width and height. THe text will be placed above the sprite, so when there is a lot of transparent space between head and the real top of the sprite it could be possible that the text gets pushed to the side.
Yep, exactly what I meant.
Quick note: image / animation sprite positions are based on the top left pixel of each image / animation frame. Text above characters is placed based on the center position of the animation normally & above the top most pixel of the animation minus the font size (more or less).
