Offsides in Soccer: Quick Overview
- A player is in an offside position if they’re in the opponent’s’ half and any part of their head, body or feet is closer to the goal line than both the ball and the second-to-last defender at the moment a teammate plays the ball.
- Being in an offside position is not an offense by itself. A player is only penalized when they get involved in active play (touching the ball, interfering with opponent or gaining an advantage).
- An offside offense is punished with an indirect free kick for the defending team from the spot of the call.
There are plenty of confusing rules in sports, but few spark more debate among casual soccer fans than offside. The flag goes up, a goal gets wiped off the board and half the room is left asking what exactly just happened.
With the 2026 FIFA World Cup™ bringing a wave of new viewers to the sport, here’s a clear, complete guide to how offside in soccer actually works.

What Is Offside in Soccer?
A player is in an offside position when they’re in the opponents’ half and any part of their head, body or feet is closer to the goal line than both the ball and the second-to-last defender at the moment a teammate plays the ball.
Being in that position in itself is fine, but if the player becomes involved in the play, that’s when an offside call will be made.
The key distinction is between an offside position and an offside offense. Those aren’t the same thing, and most confusion comes from mixing them up.
The rule itself is found in Law 11 of the IFAB Laws of the Game, which govern soccer worldwide, including FIFA competitions such as the World Cup.
Offside Position vs. Offside Offense
One of the biggest misconceptions in soccer is that standing in an offside position automatically results in a whistle. That isn’t the case.
A player can be standing beyond the defensive line and still be perfectly legal if they aren’t involved in the play.
An offside offense occurs only when a player in an offside position:
- Interferes with play by touching or playing a ball from a teammate
- Interferes with an opponent by blocking vision, challenging for the ball or affecting an opponent’s ability to play it
- Gains an advantage by playing a ball that rebounds or deflects to them from the goal frame, an official or an opponent
That’s why you’ll occasionally see a player standing offside while the referee allows play to continue. Position alone isn’t enough.
How Is the Offside Line Determined?
The offside “line” isn’t actually painted on the field. It’s an imaginary line based on the second-to-last defender.
This is where things can get confusing. In most cases, the goalkeeper is the deepest defender, so the offside line usually appears to be set by the last field player. But the rule isn’t specifically about the goalkeeper. It’s always based on the second-to-last opponent, no matter which players are closest to the goal.
If the goalkeeper charges out of position, the line is still drawn from the second-to-last defender. That could be a center back, a fullback or even another player tracking back toward goal.
A few important details about the offside rule:
- Offside is judged when the ball is played: The decision is made the instant a teammate passes or touches the ball, not when the receiving player gets it. That’s why an attacker can sprint behind the defense and still be onside if their run started at the right moment.
- Even is onside: If an attacker is even with the second-to-last defender or even with the ball, they’re considered onside. The attacker must be beyond that line to be penalized.
- Arms and hands don’t count: Offside is measured using parts of the body that can legally score a goal. An extended arm can’t make a player offside, but a shoulder or foot can. For VAR reviews, the upper boundary used for measurement is generally the bottom of the armpit.
When Doesn’t Offside Apply?
There are several situations where the offside rule does not apply:
- Goal kicks
- Corner kicks
- Throw-ins
- When a player is in their own half
Another important exception occurs when a defender deliberately plays the ball. In most cases, an attacker who receives the ball afterward cannot be penalized for offside, even if they had been in an offside position before the defender’s touch. That said, if a ball deflects off a defender accidentally and an opponent gets it, the offsides call remains in effect.
This distinction between a deliberate play and a deflection is often one of the most debated parts of the rule.
What Happens When Offside Is Called?
When officials determine an offside offense has occurred, the defending team receives an indirect free kick from the spot where the offside player became involved in the play. There are no cards involved with offside calls.
Because it’s an indirect free kick, a goal cannot be scored directly from the restart.
How Is Offside Judged at the 2026 World Cup?
Modern offside decisions rely on technology to help ensure accuracy alongside the assistant referee’s eye. VAR (the Video Assistant Referee) reviews close calls, and major FIFA tournaments now use semi-automated offside technology. Multiple cameras track player positions and help determine exactly where each player was when the ball was played.
The technology is highly precise, but extremely close calls can still come down to tiny margins. Broadcast images have limited resolution, and officials must identify the exact frame in which the pass occurs. That’s why some reviews appear to hinge on only a few centimeters, or even less.
Why Does Offside Exist?
Without the offside rule, attackers could simply wait near the opposing goal for long passes, dramatically changing how the game is played.
Offside encourages movement, timing and tactical organization. It rewards well-timed attacking runs and forces defenders to stay coordinated.
It’s also the reason defensive teams can use an offside trap, stepping forward together to catch an attacker beyond the line before a pass is made.
