This MLS attendance listing is compiled from official MLS game reports, posted on the league’s website. We don’t list sellouts or % of capacity, as these are rather fluid measures. For instance, the Citrus Bowl seats 70,000, but Orlando City SC sells tickets only to the lower sections of the stadium. This is a good move — it creates a certain level of intimacy in a larger stadium built for big events — but with ability to open up sections of the stadium as needed, there’s really no firm number for a sellout.
