A football field is a rectangular area used for playing the sport of American football. It measures 100 yards long between the goal lines and 53.3 yards wide. Each end of the field has an end zone, which is 10 yards deep, where teams score touchdowns. The field is marked with yard lines every five yards, helping players and officials measure distances during the game. The field is typically made of grass or artificial turf, providing a safe surface for players. At each end, there are goalposts that stand 10 feet high, allowing teams to score extra points or field goals. The overall design ensures a standardized playing area for competitive matches.
