30. Despite the fact that the National Football League (NFL) has 32 teams, there are only 30 full-time NFL stadiums since the New York Giants and Jets share MetLife Stadium and the Los Angeles Rams and Chargers share SoFi Stadium. The Indianapolis Colts will move into a $1 billion facility in 2020 that will be shared with another team.
The first two stadiums built for the NFL were known as "Yankee Stadiums" because they housed both the Yankees and the Giants. The first one was called "Subway Park" because it was built above a subway line that passed right outside the door. The second one was called "Ebbets Field" after its original owner. It had a famous player named Joe DiMaggio who played for the New York Yankees during this time. He was considered by many to be the best hitter in baseball. The third stadium built for the NFL was called "Shoreham-Wading River Memorial Stadium" and was built for the New York Sea Eagles of the American Football League. They moved to Texas when the AFL merged with the NFL so this stadium was never used for football.
After these two stadiums, other teams began building their own facilities until today. Many cities have two or more NFL teams due to large regional markets.
As of the 2020 season, two teams share a stadium: the New York Giants and New York Jets at MetLife Stadium, and the Los Angeles Chargers and Los Angeles Rams at SoFi Stadium, resulting in just 30 full-time NFL venues. However, all 32 current teams have played in some form of shared facility at one time or another during their histories.
The first shared stadium was Forbes Field, now known as Budweiser Gardens. The home of the Pittsburgh Pirates from 1920 to 1960, it also hosted the Baltimore Orioles from 1961 to 1971. In 1972, a new Orioles ballpark opened across the street from Forbes Field called Oriole Park at Camden Yards. But the O's left Camden Yards for a new park in 2016 (see "What is the story behind these teams' names?" below).
The second shared stadium was Stanford Stadium. It was the home of the San Francisco 49ers from 1947 until 1995. The site now houses Levi's Stadium, which has been the home of the 49ers since 2011 and U2's World Tour Arena since 2017.
The third shared stadium is Texas Memorial Stadium. Opened in 1950, it has hosted six different NFL teams over its history: the Dallas Texans/Dallas Cowboys (1950-1952), Houston Oilers (1963-1984), and Houston Texans (2002-present).
The fourth shared stadium is Wembley Stadium.
The NFL has 32 teams and 31 venues (the New York Giants and New York Jets share a stadium), with a seating capacity of 69,444. The largest stadium is FedExField in Washington, D.C., while the smallest is Manheim Stadium in Kent State University's campus city of Kent, Ohio.
The average stadium capacity is 48,924. This is calculated by dividing the total number of tickets sold for all NFL games during the regular season over the past five seasons (186 games) by the total number of seats in the stadiums used by those teams (171).
Stadiums are allocated certain numbers of tickets based on their location, so each team plays some home games at smaller facilities. These tickets are not included when calculating the average capacity.
For example, the Oakland Raiders play most of their home games at O.co Coliseum, which has a capacity of 54,474. However, due to its location near Oakland International Airport, many fans arrive late for games and leave before the end, resulting in fewer than 50,000 people attending each time the Raiders play there. To account for these lower attendances, the average capacity of O.co Coliseum is estimated to be around 45,000.
