How long is Dallas Cowboys field?

60 minutes...same as for every other team...unless there is overtime There are four quarters in each game, and the quarters are 15 minutes long. Therefore, a game is 60 minutes long. But if the game is tied at the end of the 4th quarter, they play one additional 15-minute overtime period. In real time, it takes about three hours to play a 60 minute game, due to incomplete passes, timeouts and TV commercials.
