According to Disney Archives Los Angeles the female discs were the size of the Deluxe Sam Flynn disc. There were also 12 & 13 inch discs that were used by back ground as "carrying" discs. Which had to be in the scene when all the extra's were running around in Castors bar during the fight sequence, since there are not other scenes that made final cut of people walking around with discs in their hands. Some stunt discs were made of impact rubber and were between 12 & 13 inches too. The "hero" male discs were 10 inches total. The disc that was auctioned at Profiles was not Quoras disc.
