Why Does an NFL Kickoff Out of Bounds Put the Ball at the 40?
On a standard NFL kickoff from the kicking team’s 35-yard line, an untouched kick that goes out of bounds between the goal lines usually gives the receiving team the ball at its own 40. The math is 25 yards from the spot of the kick. But “the ball automatically goes to the 40” is only shorthand: the receiving team can have other placement options, a safety kick uses a different distance, and a ball touched last by the receiving team is not the same foul.
The controlling language is Rule 6, Section 2, Article 4 of the 2026 NFL Rulebook. It covers two related failures: a free kick that goes out of bounds between the goal lines and a kickoff or safety kick that first lands or touches a player before reaching the landing zone.
Why the standard answer is the 40-yard line
Most kickoffs begin at the kicking team’s 35. Rule 6-2-4 allows the receiving team to take possession 25 yards downfield from the spot of the kick. Advancing 25 yards from the kicking 35 reaches the receiving team’s 40. That is why the referee commonly announces that an untouched kickoff out of bounds will be placed at the 40.
The rule is written as a distance from the kick, not as one permanent yard line. If a distance penalty changes the kickoff spot, the 25-yard calculation moves with it. A safety kick is different again: its standard placement option is 30 yards from the spot of that kick.
What counts as the foul
The kicking team violates the article in any of three ways. First, it kicks the ball directly out of bounds between the goal lines. Second, it is the last team to touch the ball before the ball crosses a sideline. Third, on a normal dynamic kickoff, the ball first touches the ground or a player before reaching the front of the landing zone.
The landing zone begins at the receiving team’s 20-yard line and extends to the goal line. A short kick that hits the ground or a player before that front line is dead under the kickoff rules. Rule 6-2-4 then gives the receiving team the same type of favorable placement protection used for a sideline mistake.
The receiving team’s choices
The receiving team is not required to accept a single predetermined spot. Depending on where the ball went out, landed, or was first touched short of the landing zone, it can choose the option that gives it the most useful field position under the article.
Kick result | Primary receiving-team option | Important detail |
|---|---|---|
Standard kickoff from the 35 goes untouched out of bounds | Possession 25 yards from the kick: the receiving 40 | The team may use the out-of-bounds spot when the rule makes that option available |
Safety kick goes out of bounds | Possession 30 yards from the kick | Safety kicks use 30, not 25 |
Kick first lands or touches a player before the receiving 20 | Possession 25 yards from the kick, or the short-kick spot when applicable | The play is dead because the ball failed to reach the landing zone |
Receiving team is last to touch before the ball goes out | Ball at the inbounds spot corresponding to where it exited | This is not charged as the kicking team’s untouched out-of-bounds error |
Kick goes through or out of the end zone | Touchback placement under Rule 6-1-5 | End-zone results are governed separately from sideline out of bounds |
How officials enforce it
A sideline official identifies the point where the loose ball crossed the boundary. The crew also determines which team touched it last and whether the ball ever reached the landing zone. Those facts decide whether Rule 6-2-4 applies and which placement options the referee presents to the receiving team.
The receiving team then selects its best legal result. On the ordinary kickoff-from-the-35 example, taking the ball at the 40 is almost always preferable to accepting a deep out-of-bounds spot. The article protects the return team from being pinned by a kick it had no legal chance to field inbounds.
Example 1: untouched kick sails out at the 12
A kicker starts from his own 35 and tries to place the ball near the right sideline. The ball never touches a player and crosses the sideline at the receiving team’s 12-yard line. Because the kicking team sent it out between the goal lines, Rule 6-2-4 applies.
The receiving team does not have to start at the 12. It can choose the 25-yard-from-the-kick option, which puts the ball at its own 40. The common television phrase “kickoff out of bounds, ball at the 40” is accurate in this standard setup.
Example 2: the return team touches it first
This time the kick reaches the landing zone near the sideline. A receiving-team player reaches for it at the 22, the ball glances off his arm, and it crosses the sideline at the 18. The receiving team was the last team to touch the ball before it went out.
That touch changes the ruling. The receiving team puts the ball in play at the inbounds spot corresponding to where the ball exited. It does not get the untouched-kick placement at the 40. The rule prevents a returner from turning his own final touch into a free field-position award.
The short-kick part fans often miss
Rule 6-2-4 is not only about the sideline. Under the dynamic kickoff, a normal kickoff must reach the landing zone. If it first strikes the ground or any player before the receiving team’s 20, the play is dead and the receiving team receives the article’s placement choices.
That stops the kicking team from using an undeclared dribbler or pop-up kick to create chaos in front of the landing zone. A declared onside kick uses its own formation, restraining lines, and touching rules; it should not be confused with a normal kickoff that simply falls short.
Important exceptions and boundaries
A ball that exits behind the receiving team’s goal line is a touchback, not a sideline out-of-bounds foul. The 2026 rulebook uses different touchback spots depending on whether the ball first touched the landing zone and whether a kickoff originated at the 50. Those outcomes belong to Rule 6-1-5, not Article 4.
A receiving-team touch also matters only if that team is last to touch before the sideline. If the returner touches the ball and a kicking-team player subsequently touches it before it exits, the kicking team is last to touch and Rule 6-2-4 can apply. Officials therefore track both the boundary and the touch sequence.
The most common misunderstanding
Fans often treat every kickoff that reaches a white boundary as “ball at the 40.” That skips three questions: Did the ball go out between the goal lines or behind the end zone? Which team touched it last? Where was the kick made? Answer those first, and the enforcement becomes much easier to predict.
What to watch for
Watch the nearest sideline official for the out-of-bounds spot, then look for a discussion about a possible touch. If the ball died before the receiving 20, listen for language about failing to reach the landing zone. Finally, check the kickoff spot on the scoreboard; the familiar 40-yard result assumes the kick began at the 35.

Football Nation conclusion
The ball goes to the 40 after a standard untouched kickoff out of bounds because the receiving team may take possession 25 yards from a kick made at the 35. That is the common result, not the complete rule. Safety kicks use 30 yards, adjusted kickoff spots change the math, a receiving-team final touch changes the enforcement, and an end-zone exit becomes a touchback. Track the kick spot, the boundary, and the last touch, and the ruling stops looking automatic—or mysterious.
