how long is a quarter in a nfl football game
American football Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.[71][72] High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes.[73] The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break.[71][72][74] Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.[75] Teams switch goals following the first and third quarters.[76] If a down is in progress when a quarter ends, play continues until the down is completed.[77][78][79]
Field goal The longest field goal kick in NFL history is 64 yards, a record set by Matt Prater on December 8, 2013. The previous record was 63, originally set by Tom Dempsey and then matched by Jason Elam, Sebastian Janikowski, and David Akers. High school, college and most professional football leagues offer only a three-point field goal; however, some professional leagues have encouraged more rare kicks through four-point field goals. NFL Europe encouraged long field goals of 50 yards or more by making those worth four points instead of three (much like Australian rules' Super Goal or basketball's three-point line), a rule since adopted by the Stars Football League. Similarly, the sport of arena football sought (unsuccessfully) to repopularize the drop kick by making that worth four points; it failed, since only one kicker (Brian Mitchell) was able to do it with any semblance of proficiency. (In six-man football, where there is no offensive line, all field goals are worth four points instead of the usual three.)
