The heavyweight boxing title match between Vitali Klitschko and Danny Williams will be the biggest heavyweight fight ever. Biggest, that is, as measured by the scale.

Klitschko officially weighed in at 250 pounds Thursday to 270 pounds for Williams, breaking the record for combined weight in a heavyweight title fight.

Williams also tied the mark for heaviest title fighter ever, set in 1934 by Primo Carnera. Williams said afterwards that he is not worried about his weight as he is in shape and it is much what he expected when he stood on the scale.

Together, Klitschko and Williams weigh 520 pounds, breaking the old mark of 504½ set by Klitschko and Lennox Lewis when the two faced each other in June 2003.
