Each end zone is 10 yards deep.   A field goal is scored by kicking the football within a certain area of the goal posts. This area begins just over the 10 foot high horizontal bar and extends between the two vertical ones, a span of 18 feet and 6 inches.   A regulation football is 11-11.25 inches long and weighs 14-15 ounces.   In the current NFL, there are thirty teams in two conferences. Each conference has 3 divisions. At the end of the regular season, the teams with the best record in each division, plus 3 "wild card" (teams with the next best records), advance to the playoffs. The Super Bowl is played by the champions of each conference. -end- Learn More! or All steps at once (printable version)
