I actually thought about this a few days ago, and so checked into it. Only got about three people, before it became way to tedious, and I gave up. Here are the ones I got were:Alicia ......5'4"
Jerri........5'6"
Jeff.........5'9"
and I believe lex was like 6'1" (but can't be sure)
obviously rupert and tom don't fit, so I didn't even look these up.
and the other survivors tend to be around the alicia or jerri height, so I think it could be just about anyone if you use this logic. I mean you can stand 10 feet away or so, and look 5 or 6 inches up or down, and your eyes wouldn't really show a variance.
