The Offside Rule Explained: Reading Flags and VAR at the 2026 World Cup
At every World Cup, the offside rule sparks more debate and confusion than almost any other decision. A goal can be ruled out by a matter of centimetres. This guide breaks down offside according to IFAB’s Laws of the Game, Law 11, so you can read every flag from the assistant referee and VAR at the 2026 World Cup.
What counts as an “offside position”
A player is in an offside position when two conditions are met at once: any part of the head, body or feet is in the opponents’ half, and that part is nearer to the opponents’ goal line than both the ball and the second-last opponent. Hands and arms are not counted, including the goalkeeper’s. A player level with the second-last opponent or level with the ball is considered onside.
Being offside is not the same as an offence
This is the most overlooked point: simply standing in an offside position is not an offence. A player is only penalised if, at the moment a team-mate plays or touches the ball, they become involved in active play. That includes touching or challenging for a ball passed by a team-mate, obstructing an opponent’s line of vision or movement, or gaining an advantage (for example from a rebound off the post or an opponent). The decisive instant is always when the team-mate plays the ball, not when it is received.
When offside does not apply
The Laws list clear exceptions: there is no offside if a player receives the ball directly from a goal kick, a throw-in or a corner kick. These three restart situations are a common blind spot for fans. A player also cannot be offside in their own half, so on a fast break the position is judged at the moment the team-mate releases the ball.
VAR and semi-automated offside technology
Recent World Cups have used video assistant referees (VAR) alongside semi-automated offside technology, combining multi-camera tracking and ball-sensor data to judge marginal calls more precisely. The technology speeds up decisions and reduces the margin of human error, but the final call still rests with the on-field officials. Once you understand the logic above, it becomes clear why some goals are disallowed after a lengthy review.
Frequently Asked Questions
Is a player level with the last defender offside?
No. Being level with the second-last opponent or level with the ball is onside.
Can you be offside directly from a corner?
No. There is no offside from a corner kick, goal kick or throw-in.
Is standing in an offside position always safe if you don’t touch the ball?
Not necessarily. Blocking the goalkeeper’s vision or interfering with a defender can still be an offside offence.
