That's the opposite of what I heard, that breathing mostly produces droplets. But I wouldn't be surprised if it's wrong, it seems like this area of research is not well understood by public health professionals. Regardless of droplets or aerosols, sneezes definitely have a high velocity and travel further than 2m. And yes it's a curve so the risk depends on the minimal infective dose. If you can get infected by a small number of virus particles (which is apparently the case) then you need more distance.
