Offside Rule in Soccer Explained: The Simple Guide for American Fans

Offside is the rule that confuses more new soccer fans than any other, and it is the reason a goal can be celebrated, reviewed and taken away a minute later. The good news: the offside rule is simple once you know what to look at. Here it is in plain English.

Why Offside Exists

Without offside, attackers could stand next to the opponent's goalkeeper and wait for a long ball. The rule keeps teams compact and makes defending and attacking a battle for space.

The Offside Position

A player is in an offside position if, at the moment a teammate plays the ball, all three of these are true:

1. They are in the opponent's half of the field.
2. They are closer to the opponent's goal line than the ball.
3. They are closer to the goal line than the second-to-last opponent.

The second-to-last opponent is usually the last defender, because the goalkeeper is normally the last one.

Being Onside

A player is onside if they are:

• Level with the second-to-last opponent
• Level with the ball, or behind it
• In their own half when the ball is played

Which Body Parts Count?

Offside is judged on any part of the body a player can legally score with: the head, body and feet. The hands and arms do not count, for attackers and defenders alike.

Offside Position Is Not Always an Offense

Standing in an offside position is not an offense on its own. A player is penalized only if they become involved in active play by:

• Playing or touching the ball passed by a teammate
• Interfering with an opponent, such as blocking the goalkeeper's line of sight or challenging for the ball
• Gaining an advantage from being there, such as playing a ball that rebounds off the post, the goalkeeper or a defender

That is why the assistant referee sometimes waits before raising the flag.

When There Is No Offside

A player cannot be offside when receiving the ball directly from:

• A throw-in
• A goal kick
• A corner kick

What Happens After Offside

When offside is called, the defending team gets an indirect free kick from the spot where the offending player was when the ball was played.

How VAR Checks Offside

In top leagues, the Video Assistant Referee (VAR) checks every goal for offside. Operators freeze the video at the moment the ball is played and draw lines across the field from the attacker's and defender's furthest scoring body parts. Some competitions now use semi-automated offside technology, with cameras tracking players' limbs to speed up the decision.

Offside Myths

• "The goalkeeper counts as the last defender." Only if the keeper is the second-to-last opponent, which is rare.
• "You are offside if you are past the defender when you receive the ball." No: what matters is your position when the pass is played, not when you receive it.
• "Any part of you over the line is offside." Only body parts you can legally score with count.
