Jack Trice Stadium, home of the Iowa State Cyclones, expanded from 46,721 to 55,000 in 2007 and in 2015 expanded to 61,500. The Cyclones sold out their first two games of the season, so the expansion isn’t going to waste.
Memorial Stadium’s listed capacity is 50,071. Since KU hasn’t drawn a crowd that big since 2009, we won’t hold the Cyclones’ capacity advantage against them in comparing crowd sizes for this decade between the schools.
Both schools have had 49 home games so far this decade.
Iowa State has drawn 2,605,352 spectators, an average of 53,170. Kansas has drawn 1,736,83, an average of 35,446.
