The Rules of Soccer: Offsides Explained

The offside rule is one of the most complex rules in soccer. This rule can be challenging to understand, especially if you're new to the game. The short definition: the rule prohibits you from being behind the last defender, not including the goalkeeper.

The offside rule is essential because it prevents players from interfering with the other team's offense. In this article, we'll discuss what offsides is and how it affects your game—plus tips on how to ensure you're not a frequent offender.

What is the offside rule in soccer?

An offside foul is the most common type of foul in soccer. This foul is called when any part of a player's body crosses over both touchlines or either penalty area line before your teammate plays the ball back towards their own goal (and before it touches another player). 

Offside is one of the most confusing and at times, controversial calls in the game of soccer. A player is in an offside position when any part of the player's body (excluding hands and arms) is behind the last defender before the ball is played to them. 

For a call to be made against someone for being offside, they must be in an "offside position" when their teammate kicks or passes the ball forward (toward the goal). They must also be in their opponent's half of the field, also known as your attacking half. 

What else should I know about the offside rule?

  • A player is behind the last defender in the attacking half of the field before the ball is played to them
  • A player cannot be in an offside position during a throw-in
  • A player can only be offsides if there are in the opponents attacking half, meaning, you cannot be in an offside position as a defender on your half of the field.
  • If you are in an offside position, the assistant referee will raise their flag, signaling where you are offside and the other team will get the ball. 

Improve your soccer IQ

Learn the rules to play a fair game and improve your mental understanding of the game.

  • The offside rule is one of the most confusing aspects of soccer, so it's essential to understand how it works. Even though this can be difficult to grasp at first, it's worth learning because it will help you avoid turning the ball over and become not only a better-attacking player but defending player as well.
  • Always be aware of where your opponents and teammates stand in relation to where you are located on the field at any given moment (i.e., "position"). This will ensure that none of them get too far ahead or behind you. Keep track of whether any potential passes may result in an offside violation if made without proper consideration by both parties involved--yourself included.

Practice makes perfect!

Great work. You've taken the first step by learning what exactly the offside rule is. To avoid getting caught in an offside position, make sure you keep this information top of mind. As you continue to play more and get familiar with the game, this will become second nature. 

Next, grab a ball and a teammate, family member, or friend who understands the concept and walk through a few game-like examples of when this could happen so you can visualize. Most importantly, have fun!
