Here is a recent (2007) link of her standing next to NFL player Clinton Portis... http://sports.webshots.com/photo/2732900220067240597UPLcuM?vhost=sports Portis is 5'11" and Dana is almost the same height (I'm guessing she's 5'10") when you figure in the goofy wig Portis is wearing. She looks great on and off camera, and carries her height very well! I'm guessing about 5'8". Here is a link to a picture of her standing next to WNBA Cynthia Cooper, who is listed at 5'10" and Dana appears to be a couple of inches shorter.
