Football Rules Explained: All 17 Laws of the Game (2026 Guide)

Football is hands down the world's most popular sport, boasting more than 250 million active players across the globe. Whether you're lacing up your boots for the first time, coaching a local youth team, or just screaming at the television from your living room, understanding the core rules of football is essential to fully appreciating the beautiful game.

In this comprehensive guide, we are breaking down all 17 Laws of the Game—the official rules that govern football worldwide.

What Are the 17 Laws of Football?

The 17 Laws of the Game are the official rulebook created and maintained by the International Football Association Board (IFAB). From your weekend amateur leagues to the FIFA World Cup, these laws dictate how the game is played. They cover everything you can imagine: field dimensions, ball specifications, fouls, offsides, and the authority of the referee.

Law 1: The Field of Play

Before you can play, you need the right pitch. The football field must be rectangular and marked with continuous boundary lines.

Key Requirements:

• •
  Length: 90–120 meters (100-130 yards)
• •
  Width: 45–90 meters (50-100 yards)
• •
  The goal area and penalty area must be clearly marked.
• •
  Goals must be placed precisely at the center of each goal line.

[!TIP] Pro Tip: Familiarizing yourself with pitch markings helps you understand where crucial set pieces like penalties, goal kicks, and corner kicks happen.

Law 2: The Ball

You can't have a match without a proper football. The match ball must meet highly specific size and weight regulations.

• •
  Circumference: 68–70 cm
• •
  Weight: 410–450 grams at the start of the match
• •
  Shape: Spherical

If the ball gets damaged during play, the referee will immediately stop the match and restart it with a dropped ball using a replacement.

Law 3: The Players

Football is an 11-a-side game. Each team starts with a maximum of 11 players on the pitch, one of whom must be the designated goalkeeper.

• •
  Minimum players: A team must have at least 7 players to start or continue a match.
• •
  Substitutions: Teams can make substitutions according to specific competition rules (usually up to 5 in modern professional leagues).
• •
  Goalkeepers: Only the goalkeeper can handle the ball, and they can only do so within their designated penalty area.

Law 4: The Players' Equipment

Safety comes first. Players are required to wear mandatory equipment and are strictly prohibited from wearing anything dangerous.

Required Gear:

• •
  A jersey with sleeves
• •
  Shorts
• •
  Socks
• •
  Shin guards (completely covered by the socks)
• •
  Appropriate football boots

[!WARNING] All jewelry, including rings, bracelets, and necklaces, is completely banned during a match to prevent injuries.

Law 5: The Referee

The referee is the ultimate boss on the pitch. They have the full authority to enforce the Laws of the Game from the moment they enter the field to the moment they leave.

Core Responsibilities:

• •
  Acting as the official timekeeper.
• •
  Stopping, suspending, or abandoning the match for any infringements.
• •
  Issuing yellow and red cards.
• •
  Ensuring player safety and treating injuries.

The referee's decisions regarding facts connected with play are final.

Law 6: Other Match Officials

The referee rarely works alone. Modern football relies on a team of officials to ensure fair play.

• •
  Assistant Referees (Linesmen): Help judge offsides, throw-ins, and fouls near the touchlines.
• •
  Fourth Official: Manages substitutions, injury time, and technical areas.
• •
  Video Assistant Referee (VAR): Uses video replays to check goals, penalty decisions, and direct red card incidents.

Law 7: Duration of the Match

A standard professional football match lasts for exactly 90 minutes of regular play.

• •
  First Half: 45 minutes
• •
  Second Half: 45 minutes
• •
  Halftime Break: Maximum of 15 minutes

The referee will add "stoppage time" at the end of each half to account for time lost due to substitutions, injuries, goal celebrations, or VAR checks.

Law 8: The Start and Restart of Play

Every half, and the restart after every goal, begins with a kick-off from the center circle.

If the referee has to pause play for a reason not covered by the laws (like an injury or a burst ball), the match restarts with a dropped ball. The ball is only considered "in play" when it clearly moves.

Law 9: The Ball In and Out of Play

This law is remarkably simple but causes a lot of arguments. The ball is only out of play when:

• •
  It has completely crossed the goal line or touchline, whether on the ground or in the air.
• •
  The referee has officially stopped play.

[!IMPORTANT] If even a millimeter of the ball is overhanging the line, it is still in play!

Law 10: Determining the Outcome

The ultimate objective of football: the team that scores the most goals wins the match.

If both teams score the same number of goals, or if no goals are scored, the match ends in a draw. However, in knockout tournaments where a winner must be decided, matches may go to extra time (two 15-minute halves) and, if necessary, a penalty shootout.

Law 11: Offside

Offside is famously the most confusing rule for newcomers. It exists to stop attackers from "goal-hanging" near the opponent's goal.

You are in an offside position if any part of your head, body, or feet is nearer to the opponent's goal line than both the ball and the second-last defender (usually the last outfield player, since the goalkeeper is the last defender).

However, being in an offside position isn't an offense on its own. You are only penalized if you become involved in active play.

You cannot be offside:

• •
  In your own half of the pitch.
• •
  Directly receiving a goal kick, throw-in, or corner kick.

Law 12: Fouls and Misconduct

This law covers all the things you shouldn't do on the pitch and the punishments for doing them.

Common Fouls:

• •
  Tripping or kicking an opponent
• •
  Pushing or holding
• •
  Deliberately handling the ball (handball)
• •
  Reckless or dangerous tackles

Disciplinary Actions:

Yellow Card (Caution): Given for unsporting behavior, dissent, delaying the restart of play, or persistent fouling.

Red Card (Dismissal): Given for serious foul play, violent conduct, offensive language, or denying an obvious goal-scoring opportunity. A player who receives a red card is sent off and cannot be replaced.

Law 13: Free Kicks

When a foul occurs outside the penalty area, a free kick is awarded.

• •
  Direct Free Kick: You can score a goal directly from the kick without anyone else touching it.
• •
  Indirect Free Kick: The ball must touch another player (from either team) before a goal can be scored. The referee will signal this by raising one arm straight up.

Law 14: The Penalty Kick

A penalty kick is awarded when a player commits a direct free-kick offense inside their own penalty area.

• •
  The ball is placed exactly on the penalty mark (12 yards out).
• •
  The defending goalkeeper must keep at least part of one foot on the goal line until the ball is kicked.
• •
  All other players must remain outside the penalty area and penalty arc until the kick is taken.

Law 15: The Throw-In

When the ball completely crosses the touchline (sideline), play restarts with a throw-in awarded to the opponents of the player who last touched the ball.

Proper Technique:

• •
  Face the field of play.
• •
  Have part of each foot either on the touchline or on the ground outside the touchline.
• •
  Throw the ball with both hands from behind and over the head.

A foul throw will result in the throw-in being awarded to the opposing team.

Law 16: The Goal Kick

A goal kick is awarded when the attacking team gets the last touch on the ball before it crosses the defending team's goal line (without a goal being scored).

Any player from the defending team can take the kick from anywhere inside the six-yard goal area. The ball is in play the moment it is kicked and clearly moves.

Law 17: The Corner Kick

A corner kick is awarded when the defending team gets the last touch on the ball before it crosses their own goal line.

• •
  The ball is placed inside the corner arc closest to where the ball went out.
• •
  The attacking team takes the kick.
• •
  A goal can be scored directly from a corner kick against the opposing team.

Corner kicks are crucial set pieces that often lead to spectacular scoring opportunities.

Basic Football Rules for Beginners

If you are totally new to the sport, don't worry about memorizing all 17 laws immediately. Just keep these five golden rules in mind:

1. •
   Score goals: Get the ball into the opponent's net more times than they do to yours.
2. •
   No hands: Unless you are the goalkeeper inside your penalty box, keep your hands and arms away from the ball.
3. •
   Play fair: Avoid aggressive pushes, trips, and dangerous tackles.
4. •
   Stay onside: Don't lurk behind the enemy defense while your team is attacking.
5. •
   Respect the ref: The referee's whistle is law.

Master these basics, and you'll be well on your way to understanding almost every match you watch.
