I'd say he's closer to 6'2" than 6'3". I've seen him out and about a few times and he's slightly smaller than me and i'm 190cm.
Ruiz was slightly taller than Holyfield who claims 6' 2 1/2. Tyson has admitted he is 5'10 see celebheights. They have Holyfield at 6'1, which ties with Lewis and tyson. Anyway back to haye, he looked slightly taller than Ruiz, not even an inch though. So in the 6'2 range, 6'2 1/2 would be my guess. Also he looked about an inch shorter than Monett Barrett listed 6'3 in some shots. Same height as Ali to me 6'2 1/2 (see Liston fight tale of the tape). The wladimir shots (6'6 1/2) would point to 6'2 1/2 as well, top of Haye's head is wladimir normal eyeline (eyeline to top of a head in a 6ft man is 4 1/2 inches). Again 6'2 for Haye. The guys got a point about boxrec, eddie chambers at 6'1, real height 5'11. Samuel peters 6'2 real height 6ft 1/2 inch see James toney fight. Chris Aerola 6'4, real height 6'2 see Adamek 6'1 1/2 inch fight.
Valuev's about 6'6'' and Haye's considerably shorter than him. http://1.bp.blogspot.com/_SsxoEWOEV...pJBdQ/s1600/nikolai-valuev-and-David-Haye.jpg
6.2 i would say is accurate he is about an inch shorter than bellew who is 6.3 so many hevies are shorter than there listed height i thought ortiz was the 6.4 listed but then during the dave allen staredawn where allen is 6.3 ortiz ended up being he shorter man
