Basketball is a sport with a rich history and a dedicated following worldwide. The rules of the game, which govern everything from officiating and equipment to playing techniques, have evolved since James Naismith first published them in 1892. The most recent update to the international rules was approved by the Technical Commission of the International Basketball Federation (FIBA) in 2014. These rules cover equipment and facilities, regulations regarding teams, players, captains, and coaches, playing regulations, violations, fouls and their penalties, special situations, and officiating. With such a comprehensive set of rules, it is only natural to wonder if basketballs themselves are regulated and, indeed, they are. Basketballs are subject to specific guidelines regarding their size, materials, and even the grooves on their surface, which provide grip and fingertip control for players.
| Characteristics | Values |
|---|---|
| Size | For men, the official ball is 29.5 inches (75 cm) in circumference (size 7, or a "295 ball") and weighs 22 oz (620 g). For women, the official basketball size is 28.5 inches (72 cm) in circumference (size 6, or a "285 ball") with a weight of 20 oz (570 g). |
| Rules | FIBA decides, publishes and adapts the Official Basketball Rules, which are the only basketball rules recognized internationally. There are eight rules encompassing 50 articles, covering equipment and facilities, regulations regarding teams, players, captains and coaches, playing regulations, violations, fouls and their penalties, special situations, and the officials and table officials. |
| Fouls | If a player is fouled while attempting a shot and the shot is successful, the player will be awarded one additional free throw for one point. In combination with a regular shot, this is called a "three-point play" or "four-point play". |
| Time | Two fifteen-minute halves, with five minutes of rest in between. |
| Possession | Teams have five seconds to inbound the basketball. If they fail to release the basketball after five seconds, it will be counted as a turnover and possession will go to the other team. |
| Dribbling | The player must bounce, or dribble, the ball with one hand while moving both feet. If, at any time, both hands touch the ball or the player stops dribbling, the player must only move one foot. |

Basketball court and equipment regulations
The rules of basketball refer to the regulations that govern the play, officiating, equipment, and procedures of the game. While the basic rules are mostly uniform across the world, some variations exist. Most leagues or governing bodies in North America, including the National Basketball Association and NCAA, formulate their own rules. Meanwhile, the Technical Commission of the International Basketball Federation (FIBA) determines the rules for international play, which are followed by most leagues outside North America.
Court Regulations
A basketball court is typically 30.62 yards long and 16.4 yards wide, with a total playing area of 502.31 square yards or 810 square yards if run-offs and sidelines are included. The court should be marked with sidelines, baselines or end lines, and other lines. There should be at least three feet, and preferably 10 feet, of unobstructed space outside the boundaries. The sidelines and end lines should be a minimum of two inches in width, and regulation line markings should be 50mm wide in a contrasting colour to the playing surface.
Additionally, a division line of two inches in width should divide the court into two equal parts. If the court is less than 74 feet long, it should be divided by two lines, each parallel to and 40 feet from the farther end line. A restraining circle with a radius of six feet should be drawn at the centre of the court.
At each end of the court, a free-throw lane, 12 feet wide, and a semicircle with the free-throw line as its diameter should be marked. The three-point line, two inches wide, should be in the form of a semicircle at each end of the court.
Equipment Regulations
Basketball support structures are essential for basket stability and should be padded to protect athletes. These structures should be at least eight feet behind the plane of the backboard face and a minimum of seven feet above the floor. The backboard dimensions should be 1.8m by 1.22m, with a minimum thickness of 19mm. The backboard can be made of timber or transparent material and must be fitted with padding for all levels above U16. The basketball goal, or hoop, is typically 18 inches in diameter and should be positioned 3.05m from the floor.

Rules for players and teams
The rules of basketball are the rules and regulations that govern the play, officiating, equipment, and procedures of the game. While the basic rules are uniform worldwide, some variations exist. Most leagues or governing bodies in North America formulate their own rules, with the National Basketball Association (NBA) and the National Collegiate Athletic Association (NCAA) being the most important. The Technical Commission of the International Basketball Federation (FIBA) determines the rules for international play, which are used by most leagues outside North America.
- A basketball game is played between two teams, with five players on each side.
- The game is played on a rectangular floor called the court, with a hoop at each end.
- The court is divided into two halves by the mid-court line.
- The team with the basketball is on offense.
- When a player has the basketball, they must dribble with one hand while moving both feet. If both hands touch the ball or the player stops dribbling, they can only move one foot, which is called the pivot foot.
- A player can only dribble once. Once they stop dribbling, they cannot start dribbling again, or they will be called for a double-dribbling violation and lose possession of the ball.
- The ball must stay in bounds.
- Players cannot kick the ball or hit it with their fists.
- No player can touch the ball while it is travelling downward towards the basket or if it is on the rim. This is called goaltending.
- If the offensive team loses the ball out of bounds, the other team gains possession.
- Once the offensive team crosses half-court, they cannot go back into the backcourt. This is called a backcourt violation.
- The defensive team is the team without the basketball.
- The main rule for the defensive player is to avoid committing a foul, which is gaining an unfair advantage through physical contact.
- A foul can result in free throws for the fouled player's team, with the number of free throws depending on the situation.
- In 1936, the three-second rule was introduced, prohibiting offensive players from remaining near their opponents' basket for longer than three seconds.
- The first time restriction on possession of the ball was introduced in 1933. Teams were required to advance the ball over the center line within ten seconds of gaining possession. FIBA and the NBA later reduced this to eight seconds.
- The shot clock was first introduced by the NBA in 1954, requiring teams to attempt a shot within 24 seconds of gaining possession. FIBA adopted a 30-second shot clock, while women's basketball adopted a 30-second clock in 1971.
- Originally, a player was disqualified on their second foul. This limit was increased to four fouls in 1911 and five fouls in 1945 for a 40-minute game. For a 48-minute game, as in the NBA, a player is disqualified on their sixth foul.

Fouls and violations
Basketball is a fast-paced, high-energy game governed by rules and regulations that ensure it remains safe, fair and fun. While the basic rules are uniform worldwide, some variations exist. Most leagues or governing bodies in North America, such as the National Basketball Association and the NCAA, formulate their own rules. Meanwhile, the Technical Commission of the International Basketball Federation (FIBA) determines the rules for international play.
Basketball has numerous types of fouls and violations, which can be confusing for players and fans alike. A foul is described as gaining an unfair advantage through physical contact. A player who commits five fouls may be removed from play.
A referee decides when a foul has occurred. Fouls include holding, which is when a player continually uses their hands on an opposing player. This is usually called on defenders at the perimeter to keep a safe distance between the ball-handler and the basket. Holding can take the form of touching a shooter's arm or hand during or after a shot attempt, or touching the shooter after trying to steal the ball.
Another foul is when a player uses their leg or foot to throw off their opponent's balance. It is also a foul to excessively swing one's elbows and hit another player, or to make contact with a defender who has established their position in front of an offensive player.
Violations include carrying, or palming, which is like a double dribble. Players may not put the palm of their hands under the ball or carry it in one hand for too long. This is similar to holding the ball. During a free throw, players must not jump into the lane, or it will be called a lane violation. Players are also not allowed to kick the ball.
Goaltending is another violation. This is when a player interferes with a shot when it is above the rim but still on its downward path, or touches the net or rim while the ball is being shot. If goaltending is called on the defense, the shot is allowed. If it is called on the offense, the shot does not count and the defense gets the ball.

Game procedures
The rules of basketball are the regulations that govern the play, officiating, equipment and procedures of the game. While the basic rules are mostly uniform, variations do exist, depending on the level and location of the game. Most leagues or governing bodies formulate their own rules, such as the National Basketball Association (NBA) and the National Collegiate Athletic Association (NCAA) in North America, and the International Basketball Federation (FIBA) for international play.
A basketball game is played by two teams, most commonly of five players each, on a rectangular court. The objective is to shoot the basketball through the defender's hoop (mounted 10 feet high at each end of the court) while preventing the opposing team from doing the same.
The game is presided over by a referee, who decides when the ball is in play, in bounds, to which side it belongs, and keeps the time. The time is usually two 15-minute halves, with five minutes of rest in between. The team with the most goals at the end of the game wins. In the case of a draw, the game may continue until another goal is made, by agreement of the captains.
The team with the basketball is the offense. When a player has the ball, they must dribble (bounce) it with one hand while moving both feet. If both hands touch the ball or the player stops dribbling, they can only move one foot, called the pivot foot. The player can only take one turn at dribbling; if they stop and then start dribbling again, it is called a double dribble, and the ball is turned over to the other team. The ball must also stay in bounds.
If the offensive team loses the ball out of bounds, the other team gains possession. Once the offensive team crosses halfway, they may not go back into the backcourt, or a backcourt violation is called.
The defensive team does not have the basketball. The main rule is to avoid committing fouls, which are defined as gaining an unfair advantage through physical contact. Defensive players must not touch offensive players in a way that causes them to lose the ball or miss a shot.
Players may not kick the ball or hit it with their fists. No player may touch the basketball while it is travelling downward towards the basket or if it is on the rim (goaltending). However, touching the ball on the rim is legal in some games.
The basketball itself is also regulated. For men, the official ball is 29.5 inches in circumference and weighs 22 ounces. For women, the ball is 28.5 inches in circumference and weighs 20 ounces.
Finally, certain rule violations result in technical fouls, which are penalties for violating administrative rules. Technical fouls are commonly assessed for fighting and verbal abuse. If a player or coach receives two technical fouls in one game, they are ejected.

Basketball size and weight
Basketballs usually range in size from a few inches in diameter to extra-large balls nearly 2 feet (60 cm) in diameter used in training exercises. The size and weight of basketballs vary according to the age, gender, and level of play of the players. For instance, boys and girls between the ages of 4 and 8 use a basketball between 22 and 24.5 inches in circumference, depending on their hand size. Middle school boys (or those aged 12-14) use a 28.5-inch ball, as do all women and girls aged 12 and up. For anyone, male or female, aged 9-11, a ball size of 27.5 inches in circumference is recommended and is the most common size used in youth basketball leagues. A youth basketball could be 27 inches (69 cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball has a maximum circumference of 30 inches (76 cm) and a maximum weight of 22 ounces; the women's ball has a maximum circumference of 29 inches (74 cm) and a maximum weight of 20 ounces.
The standard size for a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm) in circumference and a pressure of 7.5 to 8.5 PSI, while the Women's National Basketball Association (WNBA) uses a ball with a maximum circumference of 28.5 inches (72 cm). The NBA and WNBA use Spalding basketballs, while the NCAA and most youth leagues use Wilson. The NBA's basketballs are the same size used throughout men's college and high school basketball leagues.
For international play, specifically FIBA, the basketball used is called a Molten GL7 for men and Molten GL6 for women. These basketballs are slightly bigger, with a circumference of 30.7 inches for the men's ball and 29 inches for the women's. The FIBA rules also state that the ball "be inflated to an air pressure such that, when it is dropped onto the playing floor from a height of approximately 1,800 mm measured from the bottom of the ball, it will rebound to a height of between 1,200 mm and 1,400 mm, measured to the top of the ball." Most leagues outside North America use the complete FIBA ruleset.

Frequently asked questions
FIBA, or the International Basketball Federation, determines the rules for international basketball play. Most leagues outside of North America use the complete FIBA ruleset.
There are several rules regarding dribbling in basketball. The player must bounce, or dribble, the ball with one hand while moving both feet. If both hands touch the ball or the player stops dribbling, they must only move one foot, which is called the pivot foot. The player can only take one turn at dribbling; once they stop, they cannot start another dribble. If they do, it is called a double-dribbling violation and the player loses the ball.
A foul is defined as gaining an unfair advantage through physical contact. The foul rule applies to all players on the court, including offensive players. A player is disqualified after a certain number of fouls, which varies depending on the length of the game.
Goaltending refers to touching the basketball while it is travelling downward towards the basket or if it is on the rim. Touching the ball on the rim is legal in some games.
Basketballs should be inflated so that if they are dropped from a height of six feet, they bounce back up roughly 50 inches. Leather basketballs, which are the most expensive type, are strictly for indoor hardwood courts only. Regulation leather balls should not be used outdoors, especially on rough concrete or asphalt surfaces.
