Offside Rule in Soccer

What Is the Offside Rule?

Core Definition

A player is offside if, while in the attacking half, they are closer to the opponent’s goal line than both the ball and the second-last opponent at the moment a teammate plays the ball forward. Source 1

Purpose of the Rule

The rule prevents attackers from “cherry-picking” near the goal or gaining an unfair positional advantage. It maintains balance between attack and defense for the 11 players on each team. Source 9

How Officials Make the Call

On-Field Decision

The referee and assistant referees judge the player’s position relative to the ball and second-last defender at the instant of the pass. An indirect free kick is awarded to the defending team from the exact spot of the offense—even if it occurs in the attacking player’s own half. Source 4

Role of VAR Technology

Video Assistant Referee reviews borderline decisions to confirm or overturn the on-field call, helping ensure greater accuracy in high-stakes matches such as the FIFA World Cup. Source 6

Common Exceptions and Misconceptions

Situations Where Offside Does Not Apply

Offside does not apply when a player receives the ball directly from a goal kick, corner kick, or throw-in. The player is also onside if they are level with the second-last opponent or the ball. Source 3

Strategic Timing

Attackers can still exploit well-timed passes and speed to move into onside positions without violating the rule.

FAQ

What happens if a player is offside but does not touch the ball?
The referee only penalizes offside if the player is deemed to be interfering with play, an opponent, or gaining an advantage.

Can a player be offside in their own half?
No—offside can only be called when a player is in the attacking half of the field.

Does the goalkeeper count as the “second-last opponent”?
Usually the last outfield defender is the second-last opponent; the goalkeeper is the last.

Is offside judged by the player’s feet, head, or arms?
Any part of the body that can legally score a goal (everything except arms and hands) is considered for offside position.

Why was the offside rule introduced?
It was created to stop attackers from loitering near the goal and to encourage skillful, passing-based play. Source 8

Will the offside rule change for the 2026 FIFA World Cup?
Law 11 remains the same, but VAR protocols and semi-automated systems will be used to improve decision speed and accuracy. Source 5
