What Is a First Down in American Football?

A third-down run that gains only two yards can still be a big play if the offense needed just one. That is the value of understanding the first down: it is the target that keeps a team’s possession alive and shapes its choices on every snap.

What a first down means

A first down is the start of a new set of downs for the offense. In most situations, a team gets four plays—called downs—to move the ball at least 10 yards toward the opponent’s goal line. Reach the required distance, and the team earns another first down with a fresh set of downs.

The 10 yards are measured from the ball’s position at the start of the series, not from where a player happens to line up. The target is called the line to gain. If the offense reaches or crosses it with the ball, the series is renewed.

For example, if a team has the ball at its own 25-yard line, the line to gain is the 35. A six-yard run makes it second-and-four. A three-yard pass makes it third-and-one. If the next play gains two yards, the offense has a first down—even though it gained only two on that play.

How the downs work

The offense’s down-and-distance tells you where it stands in the series. “First-and-10” means it is on its first play and has 10 yards to go for another first down. “Third-and-3” means it has three yards left to reach the line to gain on its third play.

If the team does not get there in four downs, the other team usually takes possession at the spot where the play ended. That is why fourth down often brings a decision: try to gain the remaining yards, punt the ball away, or attempt a field goal if the team is close enough. Teams may also choose a fourth-down attempt when the game situation makes keeping possession especially valuable.

A punt or field-goal attempt is a choice, not a requirement. If the offense tries to convert and falls short, possession changes. If it makes the required distance, it earns a new first down.

When the distance is less than 10 yards

Near the opponent’s goal line, the offense may have fewer than 10 yards to go. The goal line then becomes the line to gain. If the ball is at the opponent’s six-yard line, for instance, the offense has six yards to reach the goal line—not 10 yards to reach a spot beyond it. This situation is called first-and-goal.

First-and-goal is still a first down, but the offense cannot earn another standard first down by advancing past the goal line. It scores a touchdown by carrying the ball into the end zone or completing a catch there, subject to the rules for establishing possession. If it does not score, it can keep using its remaining downs from wherever the ball is placed.

Other situations can leave a team with a shorter distance than 10 yards, too. A penalty or a play that starts near the goal line may change the distance, so the number after “and” is not always 10.

How a first down is recorded

Officials track the ball’s position and compare it with the line to gain. Along the sideline, a crew uses two poles connected by a chain to mark the distance between the original line of scrimmage and the target. If a close play leaves doubt, officials may bring the chains onto the field to measure. The ball needs to reach the line to gain; it does not have to cross it by a full yard.

On television, a colored line is often drawn across the field to show the target. That line is a broadcast graphic, not a painted marking on the playing surface. The sideline markers and officials’ measurements determine the spot.

Some penalties can also award a first down, even when the offense did not gain the required yards during the play. Whether a foul carries an automatic first down depends on the specific rule and league. Penalties can also change the spot of the ball or the down-and-distance without awarding a new series.

Why first downs matter beyond the numbers

First downs help an offense control the pace of a game. A team that keeps converting can sustain a drive, give its defense a rest, and use up time. A defense that forces three-and-outs—possessions that end after three plays without a first down—can get the ball back quickly and put pressure on the opponent.

Down-and-distance also affects play-calling. On second-and-short, an offense has several options: run the ball, throw a deeper pass, or use a play-action fake. On third-and-long, the defense can expect a pass more often, though the offense may still run or use a screen to catch it off guard. Coaches weigh the yards needed, field position, time remaining, and score before deciding how aggressively to play.

That is why a short gain can matter as much as a long one. If a running back finds a gap for one yard on third-and-one, the offense keeps the ball. If the same run comes up short, the team faces fourth down and may have to punt or risk turning the ball over on downs.

Frequently Asked Questions

How many yards does a team need for a first down?

Usually 10 yards from the start of the series. If the goal line is fewer than 10 yards away, reaching the goal line is the target. Penalties can also affect the distance or award a first down under certain rules.

Does a team get a first down if it reaches the marker exactly?

Yes. The ball needs to reach the line to gain. Officials judge the ball’s position, and they may use the chains to check a close spot.

What happens if a team fails to get a first down on fourth down?

If it attempts a play and does not reach the line to gain, the opponent takes possession at the end of the play. The offense can instead punt or try a field goal, depending on the situation.

What does “first-and-goal” mean?

It means the offense has a first down and is close enough to the end zone that the goal line is the line to gain. The team can score a touchdown before using all four downs.

Final Thoughts

A first down is more than a yardage marker: it is the point an offense must reach to keep its drive going. Follow the down and distance, then watch how each play changes the next target. Once you do, the decisions on third and fourth down—and the importance of a seemingly small gain—become much easier to read.
