Understanding the football rules is an important part of becoming a confident player. Skills such as passing, dribbling and shooting are essential, but players also need to understand what is permitted during a match, how play restarts and why referees make particular decisions. The official Laws of the Game are maintained by The International Football Association Board (IFAB), with the current 2026/27 edition providing the framework for the game. The IFAB Laws of the Game are the authoritative reference for the full rules.
For young players, the Laws can initially seem complicated. However, the basic principles are much easier to understand when broken down into the main areas of the game. From the number of players on the pitch to offside, fouls, goals and restarts, these rules help make football fair, organised and enjoyable.
What Are the 17 Football Laws?
When people search for 17 football laws, they are usually referring to the 17 Laws of the Game established by IFAB. These laws cover everything from the field of play and football to player equipment, the referee, match officials, match duration, restarts and determining the outcome of a match.
The 17 Laws are:
- The Field of Play
- The Ball
- The Players
- The Players’ Equipment
- The Referee
- The Other Match Officials
- The Duration of the Match
- The Start and Restart of Play
- The Ball in and out of Play
- Determining the Outcome of a Match
- Offside
- Fouls and Misconduct
- Free Kicks
- The Penalty Kick
- The Throw-in
- The Goal Kick
- The Corner Kick
These laws apply broadly across football, although permitted modifications can be made for certain competitions and levels, including youth football. IFAB’s current Laws explain that national associations and competition organisers have specific options to modify certain organisational aspects of the game.
1. The Field of Play
The first law covers the football pitch. It establishes requirements relating to the field, including its dimensions, markings, penalty areas, goals and other features.
Players do not need to memorise every measurement to understand the principle. The pitch markings help everyone identify important areas such as the halfway line, penalty area, goal area and corner areas.
2. The Ball
Law 2 covers the football itself. The ball must meet the requirements established by the Laws, including specifications concerning its shape, circumference, weight and pressure.
Different age groups and competitions may use different ball sizes. Young players should therefore use the ball specified by their club, school or competition rather than assuming that every youth match uses exactly the same ball.
3. The Players
Law 3 covers the players participating in a match. In a standard 11-a-side match, each team has a maximum of 11 players on the field, with one player acting as the goalkeeper. A match cannot normally start or continue if a team has fewer than seven players under the Laws of the Game.
This explains the common question, in football how many players are on a team? In standard association football, a team can have up to 11 players on the field, including a goalkeeper.
Youth football can use different formats, such as seven-a-side or other small-sided games, so young players should always check the regulations for their particular competition.
4. The Players’ Equipment
Players must wear suitable equipment that does not present a danger to themselves or others. Basic equipment includes a shirt, shorts, socks, shin guards and footwear.
Jewellery and other items that can create a safety risk are generally not permitted. Referees can require players to correct equipment problems before they participate.
5. The Referee
The referee has the authority to enforce the Laws during the match. Their responsibilities include controlling the game, making decisions about offences and managing disciplinary action.
Young players should learn to respect the referee even when they disagree with a decision. Understanding that officials are responsible for applying the Laws helps players concentrate on their own performance rather than arguing about every decision.
6. The Other Match Officials
Depending on the competition, additional match officials may assist the referee. Assistant referees can help with matters such as the ball going out of play, offside decisions and other incidents.
Higher-level competitions may also use other officials and technology, including video assistant referee systems where the competition has adopted the relevant protocol.
7. The Duration of the Match
A standard football match consists of two equal halves of 45 minutes, although youth and grassroots competitions can use shorter playing periods.
There is normally a half-time interval between the two halves. The referee can also add time to account for certain stoppages during the match.
8. The Start and Restart of Play
Play begins with a kick-off and is restarted in different ways after particular situations. Kick-offs are used at the beginning of each half and after a goal has been scored.
Other restarts include free kicks, penalty kicks, throw-ins, goal kicks, corner kicks and dropped balls. Knowing which restart applies can help young players understand what the referee is signalling.
9. When Is the Ball Out of Play?
One of the basic football rules is knowing when play has stopped. Under Law 9, the ball is out of play when it has wholly crossed the goal line or touchline, whether on the ground or in the air, or when the referee has stopped play.
This means the whole ball must cross the relevant line. If only part of the ball crosses the line, it remains in play.
10. How Is a Goal Scored?
A goal is scored when the whole ball passes over the goal line between the goalposts and underneath the crossbar, provided the attacking team has not committed an offence.
This is an important point for young players. The ball does not need to hit the back of the net. If the whole ball has legally crossed the goal line within the goal area, a goal has been scored.
11. Offside
Offside is one of the football rules that often takes the longest for young players to understand. Being in an offside position is not, by itself, an offence.
A player can be in an offside position when nearer to the opponents’ goal line than both the ball and the second-last opponent, subject to the specific requirements in Law 11. The offence occurs when the player becomes involved in active play in circumstances defined by the Law.
Players should therefore focus not only on where they are standing but also on when the ball is played by a teammate and what happens afterwards.
12. Fouls and Misconduct
Law 12 covers fouls and misconduct. A player can commit an offence by acting in a way that breaks the Laws, including certain forms of careless, reckless or excessive physical challenges.
Depending on the offence, the referee can award a free kick or penalty kick and may issue a yellow or red card where the Laws require disciplinary action.
For young players, the key lesson is simple: competing for the ball does not mean that every physical challenge is legal. Players must learn to challenge fairly and safely.
13. Free Kicks
Free kicks are awarded after certain offences. They can be either direct or indirect depending on the offence and the applicable Law.
A direct free kick can be used to score directly against the opposing team, while an indirect free kick requires another player to touch the ball before a goal can be scored.
The referee indicates an indirect free kick by raising an arm, which remains raised until the ball touches another player or goes out of play.
14. Penalty Kicks
A penalty kick is awarded when a player commits a direct-free-kick offence inside their own penalty area, subject to the requirements of the Laws.
The kick is taken from the penalty mark, with the goalkeeper required to follow the positioning requirements specified by the Laws. Penalty kicks are therefore not simply another type of free kick; they have their own specific procedure.
15. Throw-Ins
A throw-in is awarded to the opposing team when the whole ball crosses the touchline and was last touched by a player from the other team.
The player taking the throw-in must follow the requirements of Law 15. For young players, one of the most important points is that the ball is delivered using both hands from behind and over the head, while maintaining the required foot position.
16. Goal Kicks
A goal kick is awarded when the whole ball crosses the goal line, without a goal being scored, and was last touched by an attacking player.
The defending team then restarts play according to the requirements of Law 16. Goal kicks are an important opportunity for teams to begin an attack from their defensive area.
17. Corner Kicks
A corner kick is awarded when the whole ball crosses the goal line, without a goal being scored, and was last touched by a defending player.
The attacking team takes the kick from the appropriate corner area. Corners can create scoring opportunities because teammates can move into the penalty area to attack the incoming ball.
Heading in Football
Heading in football is an important area for young players and coaches to understand because rules and competition arrangements can differ by age group.
Under the standard Laws, heading is part of normal football. However, IFAB has also approved a specific trial concerning deliberate heading for certain competitions at under-12 level and below. Under that trial, deliberate heading can result in an indirect free kick. Accidental contact with the head is not treated as an offence under the trial protocol.
This means parents and young players should check the rules of their particular youth competition rather than assuming that the same heading requirements apply to every age group.
What Is a Header in Football?
A header in football occurs when a player uses their head to play the ball. Heading can be used for passing, clearing, defending or attempting to score.
However, young players should follow the guidance provided by their coaches and competition organisers. Where a particular youth competition has restrictions on heading, those requirements take priority for that competition.
Why Young Players Should Learn Football Rules
Understanding the Laws can make football easier to play and watch. A player who knows why a referee has awarded a free kick, corner or throw-in can respond more quickly instead of becoming confused by the decision.
Rules also help players understand positioning. Offside, for example, encourages attackers and defenders to think carefully about where they are when a teammate plays the ball.
Learning the Laws should therefore be treated as part of football development alongside technical training. Players can practise skills during training while gradually learning how those skills fit into an organised match.
Football Rules Across Different Youth Formats
Not every young player competes in traditional 11-a-side football. Smaller-sided formats can use modified rules to suit the age and development of participants.
For example, futsal has its own Laws and provides a different environment for developing close control, passing and decision-making. Similarly, schools football can use competition-specific rules depending on the age group and tournament.
Inclusive programmes can also have their own adaptations. Players and parents interested in disability football should check the rules and format of the specific programme or competition.
Older adults may also encounter modified formats such as walking football, where the rules are adapted to create a different playing experience.
How to Learn the Football Rules
The easiest approach for young players is to learn the rules gradually. Start with the basics: the number of players, pitch markings, restarts, fouls, goals and the role of the referee. Once those concepts are familiar, move on to more detailed areas such as offside and disciplinary decisions.
Coaches can also explain rules during practical training. Showing players why an offence has occurred in a real football situation can be more useful than simply asking them to memorise definitions.
For the complete and current Laws, players, parents and coaches should refer to IFAB’s official 2026/27 Laws of the Game rather than relying on old summaries. The current edition is available through IFAB’s official documentation.
Learning the football rules does not mean memorising every line of the Laws. It means understanding enough of the game to make better decisions, respect officials, play safely and enjoy football with confidence.
