1. The IFAB Governance Framework
Association Football is uniquely governed by the International Football Association Board (IFAB), an independent rule-making body founded in 1886. IFAB comprises the four British football associations (England, Scotland, Wales, Northern Ireland) and FIFA. Unanimous rule amendments require a 75% majority, ensuring that changes to the core code are deeply scrutinized before worldwide rollout.
The 17 Laws of the Game form a singular, universal statutory framework applied identically across grassroots matches and the FIFA World Cup final.
2. Law 1: The Field of Play & Markings
The field of play must be a rectangular surface marked with continuous lines that do not constitute a hazard. For senior international matches, strict boundary limits apply:
Touchline length must measure between 100m (110 yd) and 110m (120 yd), while the goal line must measure between 64m (70 yd) and 75m (80 yd). Standard UEFA Champions League and Premier League pitches are standardized at exactly 105m × 68m (115 yd × 74 yd).
The penalty area extends 16.5m (18 yd) from each goalpost into the pitch, and 16.5m along the goal line. The penalty mark is positioned exactly 11.0m (12 yd) from the center of the goal line.
Under Law 1.2, all boundary markings, goal lines, and penalty lines must possess an identical width of not more than 12cm (5 inches). The goal line must match the depth of the goalposts exactly.
3. Law 2: The Ball Specifications
The official match ball must be spherical, constructed of suitable materials, and strictly calibrated before kickoff. For standard Size 5 match play:
Circumference must measure between 68.0cm (27 in) and 70.0cm (28 in). Mass at kickoff must range between 410g (14 oz) and 450g (16 oz). Internal pressure at sea level must equal 0.6 to 1.1 bar (8.5 to 15.6 psi).
4. Law 3 & 4: Players, Substitutes & Equipment
A match is contested by two teams, each consisting of not more than 11 players, one of whom must be the designated goalkeeper. A match may not start or continue if either team fields fewer than 7 players.
Under current IFAB protocols, competitions may permit up to 5 substitutions across a maximum of 3 in-game substitution opportunities (excluding halftime intervals). If extra time is played, an additional sixth substitute may be authorized.
Mandatory player equipment comprises: jersey with sleeves, shorts, stockings, shinguards made of suitable protective material, and footwear. Shinguards must be completely covered by the stockings.
5. Law 5 & 6: The Referee & Match Officials
Each match is controlled by a referee who possesses full statutory authority to enforce the Laws of the Game. The referee's decisions regarding facts connected with play, including whether or not a goal is scored and the result of the match, are final.
The referee operates in coordination with two Assistant Referees, a Fourth Official, and, where authorized, a Video Assistant Referee (VAR) and Assistant VAR (AVAR).
6. Law 7 & 8: Match Duration & Restarts
A standard regulation match lasts two equal halves of 45 minutes, plus allowance for time lost in each half for substitutions, assessment/removal of injured players, disciplinary sanctions, and VAR reviews.
Play commences from the center circle with a kick-off at the start of each half and following the concession of a goal. The ball is in play once kicked and clearly moves in any direction.
7. Law 12: Fouls & Misconduct Framework
Law 12 delineates direct free kick offenses, indirect free kick offenses, and disciplinary sanctions (Yellow and Red cards).
Direct free kicks are awarded when a player commits any of seven physical contact infractions in a manner judged careless, reckless, or using excessive force: charging, jumping at, kicking, pushing, striking, tackling/challenging, or tripping.
Denying an Obvious Goal-Scoring Opportunity (DOGSO) outside the penalty area incurs an immediate red card. Inside the penalty area, if an attempt was made to play the ball, the sanction is downgraded to a yellow card (the double jeopardy amendment introduced in 2016).
A red card leaves a team playing with 10 players for the remainder of regulation time. In competitive tournament finals, 28 red cards have been issued in FIFA World Cup history.
8. Laws 13–17: Free Kicks, Penalties & Restarts
Laws 13 through 17 govern the execution of specific dead-ball restarts: Free Kicks (Law 13), Penalty Kicks (Law 14), Throw-ins (Law 15), Goal Kicks (Law 16), and Corner Kicks (Law 17).
In all free kicks, defending opponents must remain at least 9.15m (10 yards) from the ball until it is in play, unless they are standing on their own goal line between the posts.
