If body copy is just a little smaller than a headline (80% the size, say) then the difference between the two is hazy, and the end result feels sloppy. We wanted either identity (with the headline and the copy the same size, which is visually pleasing) or a discernible difference (2x or more) that was clear and clearly intentional.
