When two teams step onto a football field Replica Handbags, each is battling for every inch it can take from the other. Each team wants to defend the field that is behind it and invade the field in front of it. Ultimately, they want to gain enough ground to score a touchdown or field goal.

In this article, you will learn about the field, the positions, and how points are scored, with a focus on professional football rules. We will also look at some basic techniques for the offense and defense. To learn more about football, read How NFL Equipment Works and How the Physics of Football Works.

Football is a game of inches played on a field measured in yards — English measurements are used to track movements on the field. Teams succeed based on how many yards they accumulate or allow. An official NFLfootball field is a rectangle that is 120 yards (110 m) long and 53 yards, 1 foot (49 m) wide. Most fields are covered in grass and set in an outdoor (open-air) stadium.

The Football Field and Football
Let’s take a look at some of the standard features of a professional football field:
  • football-diagram1Sideline – The sideline is the 6-foot-wide (1.8-meter-wide) boundary line that runs the length of each side of the football field.
  • End line – The end line is a 6-foot-wide boundary line that connects the two parallel sidelines. The end line and sideline compose the rectangular shape of the field. Two pylons flank the end of the end line.
  • End zone – The end zones are two 10-yard-wide (9-meter-wide) areas at each end of the field inside the end line. The end zone behind a team is that team’s end zone, and the end zone ahead of a team is its opponent’s end zone.
  • Goal line – The goal line is an 8-inch-wide (20-cm-wide) line that runs across the front of the end zone. Two pylons flank the end of the goal line.
  • Yard lines and hash marks – In the 100 yards (91 meters) between goal lines, hash marks on either side of the field mark each yard. At every fifth yard http://www.inhandbag.com, a solid white line runs from sideline to sideline, and at every 10 yards those lines are numbered (i.e., 10, 20, 30, 40 Replica Handbags, etc.). This crosshatch of lines gives the field its “gridiron” nickname.
  • Goalposts – Centered at the back of the end zone is a pole that extends 10 feet (3 meters) high and connects with a horizontal cross bar. On each end of the 18-foot, 6-inch (5.5-meter) cross bar is an upright post that rises to a height of 30 feet (9 meters) above the ground. A 4-inch by 42-inch (10-cm x 107-cm) ribbon is tied to the top of each upright.


The most essential piece of equipment in a football game is the ball. Official NFL footballs are handmade by Wilson Sporting Goods Co. The football is an oblong sphere and is 11 to 11.5 inches (27.9 – 29.2 cm) long. It has a lengthwise circumference of about 28.5 inches (72.4 cm) and a width-wise circumference of about 21.5 inches (54.6 cm) in the middle of the ball. It weighs between 14 and 15 ounces (397 – 425 grams). The ball consists of an inflated Replica Bags Replica Handbags, polyurethane bladder placed in cowhide covering and laced with gridcord material.Gridcord is cotton thread covered with vinyl. A three-ply, synthetic lining is sewn inside the leather covering to protect the bladder and help the football keep its distinct, elongated shape. A valve connected to the bladder protrudes through the leather and allows air to be pumped into the ball.

With the equipment identified and the field set, we can now play a game. An NFL game is divided into four quarters with an extended halftime break between quarters two and three. Each quarter is 15 minutes long. If the teams are tied after four quarters of play, they play an additional overtime period of 15 minutes. In the overtime, the first team to score wins.

While the game time adds up to one hour, it usually takes three to four hours to play a game. Teams can stop the clock by running out of bounds, throwing an incomplete pass, or calling a time-out, of which they have three per half. Time also stops for each of the two-minute warnings, observed two minutes prior to the end of the second and fourth quarters.

In the next section, we’ll look at all of the players on the field.
