Football, known as the world’s most popular sport, is governed by a set of universal laws that dictate the conduct of the game. These laws, established by the International Football Association Board (IFAB), ensure fairness, safety, and uniformity in matches across the globe. Understanding these 17 laws is essential for players, coaches, referees, and fans alike. In this article, we will explore each of the 17 rules of football, breaking down their purpose and application on the field.
1. The Field of Play
The first rule defines the dimensions and markings of the football field. The field must be rectangular, with specific requirements for the length (90 to 120 meters) and width (45 to 90 meters). It is divided into two halves, with markings for the center circle, penalty areas, goal areas, and corner arcs.
Key Points:
The field must be natural or artificial grass.
Lines must be clearly visible and adhere to the standard dimensions.
The penalty area and goal area are critical zones, influencing key gameplay actions such as penalty kicks.
2. The Ball
The second law governs the specifications of the football itself. The ball must be spherical, made of leather or other suitable materials, and have a circumference between 68 and 70 centimeters. The weight of the ball should be between 410 and 450 grams at the start of the match.
Key Points:
The ball’s pressure must be between 0.6 and 1.1 atmospheres.
If the ball becomes defective during a game, play is stopped, and a new ball is introduced.
3. The Number of Players
A football team consists of 11 players, including one goalkeeper. A match cannot start or continue if a team has fewer than seven players. Substitutions are allowed, with a maximum of five per team during competitive matches (increased temporarily due to the COVID-19 pandemic).
Key Points:
Each team can have up to 12 substitutes, depending on competition rules.
The referee must be informed before a substitution is made.
If a player is sent off, they cannot be replaced, leaving their team with fewer players.

4. The Players’ Equipment
Players must wear the appropriate kit to ensure safety and uniformity. The basic equipment includes a jersey, shorts, socks, shin guards, and boots with suitable studs. The goalkeeper must wear colors that distinguish them from other players and match officials.
Key Points:
Jewelry is not permitted.
Players must tuck in their shirts and pull their socks over their shin guards.
Any clothing that poses a risk to player safety is forbidden.
5. The Referee
The referee holds the authority to enforce the laws of the game. They have full control of the match and make final decisions on all incidents. The referee is responsible for starting and stopping play, issuing disciplinary actions, and ensuring the safety of players.
Key Points:
The referee may consult with assistant referees and the fourth official.
Decisions made by the referee are final, including goals and penalties.
The referee uses cards (yellow and red) to manage player discipline.
6. The Assistant Referees
Two assistant referees (also called linesmen) assist the referee in making decisions. They are positioned along the touchlines and help monitor offside offenses, fouls, and when the ball goes out of play.
Key Points:
Assistant referees raise a flag to signal infractions.
They also help with decisions on corner kicks, goal kicks, and throw-ins.
Communication between the referee and assistants is crucial for accurate decision-making.
7. The Duration of the Match
A standard football match consists of two 45-minute halves, with a 15-minute halftime interval. The referee may add extra time (known as stoppage time) to account for injuries, substitutions, and other delays during the game.
Key Points:
The referee determines the amount of stoppage time at the end of each half.
In knockout competitions, if the score is tied at the end of regulation time, extra time (two 15-minute halves) may be played.
If the score remains tied after extra time, a penalty shootout may be used to determine the winner.
8. The Start and Restart of Play
Play starts with a kickoff at the center of the field. After a goal is scored, the game restarts with another kickoff. The team that did not score takes the next kickoff. Other restarts include throw-ins, goal kicks, and corner kicks, depending on how the ball left play.
Key Points:
The kickoff must move the ball forward.
Opposing players must stay outside the center circle during a kickoff.
If a team violates the rules during a kickoff, the opposing team may retake it.
9. The Ball In and Out of Play
The ball is considered in play as long as it remains within the boundaries of the field, even if it touches the goalposts or corner flags. It is out of play when it completely crosses the goal line or touchline, whether on the ground or in the air.
Key Points:
The referee’s whistle is typically used to indicate when the ball is out of play.
The ball remains in play after a deflection off the goalpost or crossbar, provided it stays within the boundaries.
10. The Method of Scoring
A goal is scored when the entire ball crosses the goal line between the goalposts and beneath the crossbar, provided no fouls or infractions were committed by the attacking team. The team with the most goals at the end of the match wins.
Key Points:
If both teams score an equal number of goals, the match is a draw.
In knockout stages, a draw may lead to extra time or a penalty shootout to determine a winner.
11. Offside
A player is in an offside position if they are nearer to the opponent’s goal than both the ball and the second-last defender when the ball is played to them. However, a player is only penalized for being offside if they become actively involved in the play.
Key Points:
A player is not offside if they are in their own half of the field or level with the second-last defender.
Being offside is only penalized if the player gains an advantage by being in that position.
12. Fouls and Misconduct
Players may not commit fouls or engage in misconduct that puts others at risk or disrupts the game. Fouls can result in free kicks, penalties, or disciplinary actions such as yellow or red cards.
Key Points:
A direct free kick is awarded for serious fouls such as kicking, tripping, or handling the ball.
A yellow card serves as a warning, while a red card results in a player’s dismissal from the match.
Violent conduct, serious foul play, or offensive language leads to immediate dismissal.
13. Free Kicks
Free kicks are awarded for fouls or rule infringements. They come in two forms: direct (from which a goal can be scored directly) and indirect (which requires the ball to touch another player before a goal can be scored).
Key Points:
The opposing team must stand at least 10 yards away from the ball during a free kick.
The referee signals whether the free kick is direct or indirect.
14. The Penalty Kick
A penalty kick is awarded when a defensive player commits a direct free-kick offense within their own penalty area. The ball is placed on the penalty spot, and only the goalkeeper can defend the shot.
Key Points:
All players except the kicker and goalkeeper must remain outside the penalty area during the kick.
The goalkeeper must stay on the goal line until the ball is kicked.
15. The Throw-In
When the ball crosses the touchline, the team that did not touch it last is awarded a throw-in. The player must throw the ball from behind their head, with both feet on the ground, from the spot where the ball left the field.
Key Points:
A throw-in cannot directly result in a goal.
The thrower must not cross the touchline while executing the throw.
16. The Goal Kick
A goal kick is awarded when the ball crosses the goal line without a goal being scored and was last touched by the attacking team. The defending team takes the goal kick from anywhere within the goal area.
Key Points:
Opposing players must remain outside the penalty area until the goal kick is taken.
A goal kick can lead to direct play but must leave the penalty area before it is in play.
17. The Corner Kick
A corner kick is awarded when the ball crosses the goal line after being touched by a defending player and no goal is scored. The attacking team takes the kick from the corner nearest to where the ball went out of play.
Key Points:
A goal can be scored directly from a corner kick.
Opposing players must stay at least 10 yards away from the corner until the kick is taken.
