Offside Rule Explained Simply for 2026

By Nina Walsh · September 26, 2026

The Basic Idea

Offside prevents attackers from camping near the opponent goal. A player is offside if they are closer to the goal line than both the ball and the second-to-last defender when a teammate plays the ball to them.

Three Conditions for Offside

For offside to be called, all three of these must be true at the moment the ball is played by a teammate:

The player is in the opponent half
The player is ahead of the ball
The player is ahead of the second-to-last opponent (usually the last defender, since the goalkeeper is the last)

When Offside Does Not Apply

Throw-ins: You cannot be offside from a throw-in
Goal kicks: Offside does not apply on goal kicks
Corner kicks: You cannot be offside from a corner
Your own half: Being in an offside position in your own half is not an offense

Active Involvement

Being in an offside position is not an offense by itself. The referee only blows the whistle if the offside player becomes actively involved by touching the ball, interfering with an opponent, or gaining an advantage from their position.

The 2026 Semi-Automated VAR Update

FIFA has expanded semi-automated offside technology to more competitions in 2026. Limb-tracking cameras and ball sensors create 3D models of player positions at the moment of the pass, reducing controversial calls and speeding up decisions.

Common Misconceptions

A player can receive the ball while in an offside position if they were not offside when the ball was last played by a teammate. The critical moment is when the ball leaves the passer foot, not when the receiver touches it.
