Offside in soccer means an attacker is too far forward when a teammate plays the ball to them. A player is generally offside if they are nearer to the opponent’s goal line than both the ball and the second-to-last defender at the moment the pass is made, and then become involved in the play.

Simple example

If a striker is standing behind the defense when the pass is kicked, and then receives that pass, the referee usually stops play for offside. If the striker is level with the second-to-last defender, that is not offside.

Important exceptions

  • You cannot be called offside from a throw-in, corner kick, or goal kick.
  • You are not offside just for standing there; the player must actively affect the play.
  • Hands and arms do not count when judging offside.

Why it matters

The rule stops attackers from ā€œcampingā€ near the goal and keeps the game fair and more tactical.

In one line

Offside is basically: ā€œYou can’t be ahead of the defense when your teammate passes the ball to you, unless you’re level with them or the play comes from a throw-in, corner, or goal kickā€.

TL;DR: offside means an attacking player is too close to the opponent’s goal when the pass is made, and then joins the play.
