What Is a Down in American Football? Rules Explained

A quarterback throws an incomplete pass on first down, a running back gains four yards on second, and suddenly the crowd is shouting about third down. The down tells you where the offense is in its attempt to keep the ball—and how much it needs to do next.

What a down means

In American football, a down is one play in a series of attempts by the offense to move the ball forward. A series usually begins with first down. The offense gets four downs to advance the ball at least 10 yards and earn another first down.

That 10-yard target is called the line to gain. It is measured from the spot where the series began, not from wherever the ball happens to be after every play. If the offense reaches the line to gain before using all four downs, the count resets: the next play is first down, and the offense gets a new set of four attempts.

You’ll often hear downs and distance announced together, such as second-and-6. The first number is the down; the second is how many yards the offense needs to reach the line to gain. “First-and-10” means it is the first play of a new series, with 10 yards to go.

How the downs work

Each play ends when the ball carrier is tackled, runs out of bounds, scores, or the play otherwise becomes dead under the rules. The officials spot the ball, and the next down is determined by what happened on that play.

• Gain enough yards: The offense reaches the line to gain and earns a fresh first down.
• Gain some, but not enough: The offense moves to the next down and has fewer yards to go.
• Gain no yards or lose ground: The down still advances, and the distance may stay the same or increase.
• Incomplete pass: The down advances, but the ball generally returns to the spot of the previous snap.

For example, suppose a team starts first-and-10. A five-yard run makes it second-and-5. A two-yard completion leaves third-and-3. If the next play gains four yards, the offense has crossed the line to gain and starts a new series with first down.

Why fourth down matters

Fourth down is the offense’s final attempt in that series. If it fails to reach the line to gain, the other team takes possession at the spot where the play ended. Because losing the ball on downs can hand an opponent good field position, teams often make a strategic choice before fourth down.

• Punt: The offense kicks the ball downfield to make the opponent start farther from the end zone.
• Field-goal attempt: The team tries to score three points if it is within a realistic kicking range.
• Go for it: The offense runs or passes, aiming to gain the yards it needs and keep possession.

The decision depends on the distance, field position, score, time remaining, and the team’s confidence in its offense and defense. A team might punt on fourth-and-12 near its own goal line, but try for a first down on fourth-and-1 near midfield. There is no universal rule that a team must punt on fourth down.

Situations that change the picture

Goal-to-go

If the offense is fewer than 10 yards from the opponent’s goal line, it cannot earn a full 10 yards before reaching the end zone. The line to gain becomes the goal line, and the situation is often described as goal-to-go—for example, first-and-goal from the 7-yard line. The offense still has up to four downs to score a touchdown or make progress toward a field goal.

Penalties

Penalties can change the ball’s position, the down, or both. Some defensive penalties give the offense an automatic first down. Other fouls may add or subtract yards without awarding a new series, and some offensive penalties can include a loss of down. The referee’s announcement explains the result, so listen for both the yardage and whether a first down is awarded.

Turnovers

A fumble that the defense recovers or an interception ends the offense’s possession immediately; the opponent takes over. The offense does not have to use all four downs. That is why protecting the ball matters as much as gaining yards.

Reading the down marker

Stadium broadcasts and sideline markers usually show the down and distance. The chain crew also stretches a 10-yard chain along the sideline to mark the line to gain. The chains help officials judge close plays, although the ball’s position—not whether a player’s body crossed the marker—determines whether the offense made it. The ball must reach the line to gain.

Down and distance also shape play-calling. On third-and-short, an offense may use a run or a quick pass designed to get just beyond the marker. On third-and-long, it may need a deeper throw, a screen, or a route combination that creates room after the catch. The defense knows the situation too, and can adjust its pass rush and coverage accordingly.

Frequently Asked Questions

How many downs does a team get?

The offense gets four downs to reach the line to gain, which is usually 10 yards away. Reaching it earns a new first down and another set of four attempts.

What does third-and-10 mean?

It means the offense is on its third down and needs 10 yards to reach the line to gain. If it gains fewer than 10 yards, it will face fourth down unless a penalty changes the situation.

What happens if a team fails on fourth down?

If the offense runs or passes on fourth down and does not reach the line to gain, the opponent takes possession at the spot where the play ended. A team can choose to punt or attempt a field goal instead.

Can a penalty give a team a first down?

Yes. Certain penalties, particularly some defensive fouls, award the offense an automatic first down. Other penalties have different effects, so the referee’s ruling determines the new down and distance.

Final Thoughts

A down is one play in the offense’s effort to move the ball and keep possession. The key is tracking two things: which attempt the team is on and how far it needs to go for a first down. Once you know that, terms like third-and-short and fourth-and-goal become more than broadcast shorthand—they explain the pressure, the options, and the strategy behind the next snap.
