I think Florida Field (before BHG, before the Swamp, before SOS field in BHG at Florida Field) had a capacity of 53000 when I was there. Maybe 73000; it was a long time ago:)
Capacity
88,548 (2003–present)
83,000 (1991–2002)
72,000 (1982–1990)
62,800 (1966–1981)
46,164 (1960–1965)
40,116 (1950–1959)
21,769 (1930–1949)
Record attendance 90,916
So how can record attendance be higher than capacity?
Capacity counts seats. Attendance is everybody there including players, coaches, photographers, TV crews, bands, security, concession sales, officials, etc.
The truth? They make it up. They have no idea how many souls are actually in the building. When the sports information department decides we need to set a new attendance record, they add a dozen to whatever the last record was.
