Rules &
Disciplines

A standard basketball court measures 28 metres in length and 15 metres in width. The playing surface is divided by a mid-court line into two equal halves, each containing an offensive and defensive zone.

The key, also known as the painted area or the lane, extends from the baseline to the free-throw line. It is 4.9 metres wide in international play. Players may not remain stationary in the opposing key for more than three consecutive seconds while their team is in possession.

The three-point line is an arc drawn at a distance of 6.75 metres from the centre of the basket. Field goals made from beyond this line score three points; those made from within score two.

The restricted area arc sits directly beneath the basket, marking a zone within which a defensive player cannot take a charge from an offensive player who is driving to the basket.

A field goal scored from within the three-point arc counts for two points. A field goal scored from beyond the arc counts for three points. A successful free throw counts for one point.

The team with the most points at the end of the four regulation periods wins the game. If the score is level at the end of regulation, an overtime period of five minutes is played. Overtime periods continue until one team leads at the end of a period.

Dead-ball situations, such as out-of-bounds and fouls, temporarily halt play. Possession is then resumed via a throw-in, free throws, or a jump ball, depending on the specific ruling.

A professional basketball game consists of four periods of ten minutes each in international play, or twelve minutes in some domestic formats. A half-time break of fifteen minutes separates the second and third periods.

The game clock stops during dead-ball situations, free throws, timeouts, and when officials suspend play. This means the actual duration of a game is significantly longer than the nominal forty minutes of playing time.

Each team is permitted a defined number of timeouts per half, during which coaches can address their players, make tactical adjustments, and allow tired players to rest briefly.

The shot clock, visible at each end of the court, requires the attacking team to attempt a field goal within 24 seconds of gaining possession. If the ball strikes the rim, the clock resets to 14 seconds. Failure to attempt a shot within the time limit results in a turnover.

A personal foul is charged when a player makes illegal physical contact with an opponent. The fouled player may be awarded free throws if the foul occurred during a shooting action, or possession may be given to the opposing team if no shot was in progress.

A player who accumulates five personal fouls in a game is disqualified and may not return. Replacement must be made immediately with a player from the bench.

Technical fouls are assessed for unsportsmanlike conduct, including arguing with officials, using disrespectful language, or delaying the game. Technical fouls result in free throw attempts for the opposing team and possession of the ball.

A flagrant foul involves excessive or unnecessary contact. Flagrant fouls are divided into two categories: those that are excessive but unintentional, and those deemed intentional or particularly violent. The latter may result in immediate ejection.

Team fouls accumulate over each period. Once a team reaches a defined threshold of fouls per period, subsequent fouls result in the opposing team shooting free throws regardless of whether a shooting action was in progress.

A travelling violation is called when a ball-handler takes more than two steps without dribbling. This is one of the most commonly called violations at all levels of the game.

Double dribbling occurs when a player dribbles the ball with both hands simultaneously, or when a player picks up their dribble and then begins to dribble again. Both result in a turnover.

A ball-handler who carries the ball, placing the hand beneath it and scooping it, is called for a carrying violation. In practice, referees apply this rule with some discretion at the professional level.

Once a team has advanced the ball past the mid-court line, it may not return it to the back court. Doing so results in a backcourt violation and a turnover.

An out-of-bounds violation occurs when the ball, or a player in possession of the ball, touches the boundary line or the area beyond it. The ball is awarded to the opposing team.

Basketball is typically played with five positions on the court: point guard, shooting guard, small forward, power forward, and centre. Modern basketball has blurred many of these distinctions, but the categories remain useful for understanding traditional roles.

The point guard is the primary ball-handler and playmaker. Responsible for advancing the ball and initiating offensive sets, the point guard must combine technical skill with tactical intelligence.

The centre is typically the tallest player and operates closest to the basket. Rebounding, interior scoring, and protecting the rim on defence are the centre's primary responsibilities.

In contemporary basketball, positional versatility is valued highly. Teams that can deploy players in multiple positions create tactical flexibility that makes them more difficult to prepare against.

A basketball game is managed by a team of officials that includes two or three on-court referees, a scorer, a timekeeper, and a shot-clock operator. The on-court referees bear primary responsibility for enforcing the rules.

Officials use a standardised set of hand signals to communicate rulings to scorers, players, and spectators. Familiarity with these signals allows anyone watching a game to follow the officials' decisions in real time.

The lead official and the trail official position themselves to observe different areas of the court, ensuring maximum coverage of potential fouls and violations. Communication between officials is essential to consistent game management.
