The Offside Rule in Soccer, Explained in Plain Terms
The short version
- A player is in an offside position when in the other team's half, ahead of the ball, and beyond every opponent except one, judged by the head, body, or feet and never the arms.
- Hands and arms are never considered for any player, goalkeepers included, under wording in place by 2017.
- Position alone is not an offence; punishment requires touching the ball, affecting an opponent, or benefiting from a rebound or save after a teammate has played the ball.
- Throw-ins, corners, and goal kicks can never produce an offside offence, and a deliberate play by an opponent negates it unless that touch was a save.
- The decision is made when a teammate plays the ball, not when it is received, and each new touch by a different onside player resets it.
What the Offside Rule Means in Soccer
The offside rule, written into Law 11 of soccer's official laws, stops attackers from loitering beside the other team's goal to wait for easy balls. A player is punished only when, already in an offside position at the instant a teammate plays the ball, they then join the action in one of the ways the law defines. With the rule explained that plainly, the sections below break down the position, the offence, the exceptions, and the history.
Many people treat the law as one of the sport's most confusing parts. Its wording has been sharpened repeatedly, through guidelines in 2003, changes in 2005, a circular in 2015, and clarifications in 2017 and the 2017-18 edition, to pin down exactly what an offside player may do.
What Counts as an Offside Position
Two conditions must hold at once. First, some part of the player's head, body, or feet must be inside the half belonging to the other team, with the halfway line itself counting as part of neither half. Second, judged by those same body parts, the player must be nearer the far goal than the ball, with no more than one opponent standing closer to that goal line.
The arms never enter the arithmetic. A decision added to the 2005 edition of the laws defined the position by the head, body, and feet, and wording in place by 2017 states that every player's hands and arms, the goalkeeper's included, are ignored.
A goalkeeper is simply one of the opponents for this test. The last opponent is usually the keeper, but the rule works the same no matter which players happen to be nearest their own goal.
When an Offside Position Becomes an Offence
Standing offside breaks no law on its own. The referee penalizes a player who held that position while a teammate touched or passed the ball and who then, in the referee's judgment, becomes part of the action.
Three routes lead to punishment. One is playing or touching a ball that came from a teammate. Another is affecting an opponent, which covers blocking their clear sight of the ball, challenging them for it, trying to play a nearby ball when that affects an opponent, and making any obvious move that clearly hampers an opponent's effort on the ball. The third is gaining a benefit, meaning playing the ball or affecting an opponent after it has rebounded or deflected off a goalpost, the crossbar, a match official, or an opposing player, or after an opponent made a deliberate save.
The 2017-18 edition added one more case. A player leaving an offside position, or holding one, who blocks an opponent's path to the ball commits an offence whenever that block affects the opponent's ability to play the ball or compete for it.
The Exceptions: Restarts With No Offside
A player who takes the ball straight from a throw-in, a corner, or a goal kick cannot be called offside, wherever anyone stands. Offside also disappears when an opponent's last touch was a deliberate play of the ball, except that a save does not count as such a play.
The law defines a save narrowly. A save is a player stopping, or trying to stop, a ball heading toward the goal or passing right beside it, using anything other than their hands or arms. A goalkeeper inside the penalty area is the one permitted to use hands and still have the action count as a save.
Free kicks and dropped balls enjoy no shield. An offside offence can be given when a player collects the ball straight from a dropped ball or from a free kick, whether direct or indirect.
How and When the Referee Makes the Call
The decisive moment is the instant a teammate plays the ball, not the moment the runner collects it. A player who was legal when the pass was struck may sprint past the second-nearest opponent, or even past the very last one, without breaking the law, because an onside player may run anywhere once the ball is on the move.
Every new touch resets the decision. A player offside at a teammate's first pass is no longer at risk if another onside teammate then plays the ball before they get involved, because the determination starts over with each such touch.
How the Offside Law Changed Over Time
Offside-style rules appeared in English school football well before national laws existed, and the Football Association's first code of 1863 was severe: any attacker positioned ahead of the ball was out of play, apart from the restart used when the ball went out behind the goal, that era's version of a goal kick. In February 1866 the FA relaxed this by allowing play whenever at least three opponents stood between the attacker and the goal. The Sheffield clubs accepted that three-player standard in 1877.
The chance of being caught offside inside one's own half, which the earliest laws allowed, ended with a change introduced in 1907. The push came after a Scotland v England international in April 1906, where England's use of a one-back game repeatedly caught the Scottish wingers; a Clyde FC proposal that the Scottish association had rejected in May 1905 was then accepted.
Modern fine-tuning answered complaints that the law's key phrases lacked clear definitions. FIFA issued new interpretive guidelines in 2003, and in July 2005 they entered Law 11. IFAB circular 3 followed in 2015 to clarify when an offside player affects an opponent, and that guidance now sits in the main body of the law, along with extra detail on what counts as a save.
Frequently asked questions
Can you be offside in your own half?
No. The position requires part of the head, body, or feet to be in the other team's half. The earliest laws did allow offside in a player's own half, and that possibility ended with a change introduced in 1907.
Is there offside from a throw-in, a corner, or a goal kick?
No. A player cannot be punished for taking the ball straight from any of those three restarts. Offside can still apply from free kicks, direct or indirect, and from a dropped ball.
Do a player's arms count when offside is judged?
No. A 2005 decision defined the position using the head, body, and feet, and wording in place by 2017 made clear that hands and arms are ignored for every player, goalkeepers included.
Is just standing in an offside position an offence?
No. A player is punished only when, positioned offside as a teammate plays the ball, they then touch it, affect an opponent, or benefit from a rebound or a deliberate save.
Can an offside player stop being at risk during the same move?
Yes. Every touch by a new onside teammate wipes the slate clean, so a player caught offside at the first pass is no longer at risk once another onside touch comes before they get involved.
