A football stadium is defined as the area surrounding a regulation size football field for the spectators. There are different sizes of stadiums based on the level of the sport. High school, college, and amateur levels are classified by their overall size. The size of the school or league team as well as playing history will determine what class or level a team falls into. When a football stadium is built, it is designed according to the class or league size which helps estimate the number of spectators at one game.
High school and college level stadiums are most often built to seat 3,000 people. There may also be stadium style lighting and a few small scale concession stands. Larger high schools are able to offer team gear at games as well. The field in the center of the stadium is 120 yards long and 53 ½ yards wide. This is the standard size of an American football field. Some schools choose to integrate soccer and football fields into one to help reduce budget costs. Additionally there are three to five yards of extra green along the edge of the field. This leaves from for the teams, cheerleaders, out zones, and reporters. School teams are broken up into Divisions with each composed of three or four classes.
At the amateur level there is Division II and Division III. The higher the division number, the smaller the division size. Division III stadiums are able to seat up to 10,000 people while Division II can seat up to 40,000 people. Division I is reserved for the professional level. The average National Football League stadium can seat 70,000 people including seats in the sky boxes. A larger football stadium, such as the Los Angeles Football Stadium, or those at the amateur and professional levels will feature multiple concession stands, bathrooms, and other amenities that are not found on the high school and college level.
