American football doesn’t use “sets” in the way tennis or volleyball does. The phrase usually refers to a set of downs: the offense’s sequence of up to four plays to move the ball at least 10 yards. Understanding that sequence makes the game much easier to follow, especially when the broadcast shows something like “2nd & 6.”
What is a set of downs?
A set of downs begins when a team takes possession of the ball, or when it earns a first down. The offense then has four chances—called downs—to advance the ball 10 yards or more. The distance is measured from the spot where the ball was placed to the line the offense must reach, known as the line to gain.
If the offense reaches that line within its first three downs, it earns a new set of downs. The ball is spotted where the play ended, and the next attempt is called first down. The offense then has another four chances to gain the next 10 yards.
How to read down and distance
Down-and-distance describes both the current attempt and how far the offense needs to go for a first down:
- 1st & 10: First down, with 10 yards to gain.
- 2nd & 6: Second down, with 6 yards to go. The offense gained 4 yards on the previous play.
- 3rd & 12: Third down, with 12 yards to go. The offense needs a substantial gain to keep the drive alive.
- 4th & 1: Fourth down, with 1 yard to go. The team must decide whether to try for the first down or give the ball away.
The number after the ampersand is the distance remaining—not the number of yards gained on the last play. A run for 4 yards on 1st & 10, for example, leaves the offense facing 2nd & 6.
A simple example
Suppose a team starts a drive at its own 25-yard line. It is 1st & 10, and the line to gain is the 35. The running back gains 3 yards, making it 2nd & 7. A short pass gains 5, so the offense now has 3rd & 2.
If the next play gains 2 yards, the ball reaches the line to gain. The team earns a first down, and the next series begins with 1st & 10 at the new spot. If the play gains only 1 yard, it becomes 4th & 1. The offense can try another play, punt, or—if it is close enough to the goalposts—attempt a field goal.
Why teams often punt on fourth down
On fourth down, the offense has one final chance to reach the line to gain. If it fails, the other team generally takes possession at the spot where the play ended. That risk is why teams often punt: they kick the ball downfield to make the opponent start farther from the end zone.
A team may instead go for it on fourth down when the distance is short, the game situation calls for urgency, or the team is in a favorable area of the field. A successful attempt earns a new set of downs. An unsuccessful one can hand the opponent a short field.
Field-goal attempts are another option, usually when the team believes it is close enough for the kicker to score. The choice depends on the score, time remaining, field position, distance to the first-down line, and confidence in the offense or kicker.
Goal-to-go situations
When the offense is less than 10 yards from the opponent’s goal line, it cannot gain a full 10 yards before reaching the end zone. The down-and-distance display will usually say 1st & Goal, rather than 1st & 10. The offense still has up to four downs to score a touchdown, but the line to gain is now the goal line.
For instance, a team at the 6-yard line might face 2nd & Goal after a short run. It has not earned a new first down by getting closer; it still needs to cross the goal line to score. If it runs out of downs without scoring, the other team takes possession.
Penalties and first downs
Penalties can change the distance or even award a first down. Some defensive fouls, such as pass interference in many situations, can give the offense a first down. Other penalties move the ball but do not automatically reset the downs. The result depends on the specific foul and the level of play.
Penalties can also make a series harder. An offensive holding penalty commonly moves the ball backward and may leave the team with a longer distance to gain. That can turn a manageable 2nd & 4 into a difficult 2nd & 14.
How downs fit into the full game
A regulation NFL game has four 15-minute quarters. The teams alternate possessions, and each offense tries to move the ball downfield by completing passes, running, or using a combination of both. A touchdown is worth six points; teams can then attempt an extra point or a two-point conversion. Field goals and safeties provide other ways to score.
So, “set of downs” describes how an offense advances during a possession, not how the entire game is divided. The game itself is organized into quarters. Within a possession, the offense repeatedly earns new sets of downs until it scores, turns the ball over, punts, or reaches the end of the half or game.

Frequently Asked Questions
Does American football have sets like tennis?
No. Football games are divided into quarters, not sets. “Set” most often means a set of downs: up to four plays to gain the yards needed for a first down.
Does a team always get four plays?
It can use up to four downs, but teams often punt or attempt a field goal on fourth down. If they fail to reach the line to gain on fourth down, the opponent usually takes over.
What happens when a team gets a first down?
The ball is spotted where the play ended, and the offense starts a new set of downs. Most often, the next situation is 1st & 10. Near the goal line, it may be 1st & Goal.
Can a penalty create a first down?
Yes. Certain penalties, especially some defensive fouls, can award an automatic first down. Other penalties change the ball’s position or the distance to gain without resetting the downs.
Final Thoughts
When you see a down-and-distance display, focus on two things: which attempt the offense is on and how many yards it needs to reach the line to gain. The four-down system explains why teams balance aggressive plays with punts and field goals—and why a short gain on third down can set up a crucial fourth-down decision.
