The semicircles under a basketball net are known as the restricted area or restricted zone. They are located in the lane under the basketball hoop and are marked by a semicircle that extends 4 feet out from the centre of the hoop. This area is also known as 'the paint' because it is painted on the court. The restricted area was introduced to reduce the risk of dangerous collisions between players and to make it easier for referees to call charges. The rules around the restricted area have been evolving since its introduction, with the NCAA removing it from women's basketball games in the 2023-24 season.

What You'll Learn
The restricted area's purpose
The semicircle under a basketball net, also known as the restricted area, serves a crucial purpose in the game. Colloquially, this area is also referred to as 'the paint' because, in most gyms, it is painted. This restricted area has been a part of professional basketball games since 1997 and college basketball games since 2012.
The primary purpose of this area is to enhance player safety by reducing the risk of collisions between offensive and defensive players under the basket. Before the introduction of this arc, help defenders could position themselves near the basket, hoping to draw charges on any driving player, often leading to dangerous collisions. The restricted area offers offensive players more space to operate without the constant fear of collisions. This implementation has also made the infamous block/charge call less subjective for referees. If a secondary defender tries to draw a charge within this area, they will automatically be called for a blocking foul. This rule encourages offensive flow and prevents players from setting up permanently under the basket.
The restricted area is a semi-circular arc that extends four feet out from the centre of the basket to the front edge of the backboard. The backboard itself is typically made of timber or transparent material and is 1.8m x 1.22m with a minimum thickness of 19mm. The basket, or hoop, is positioned 3.05m from the floor, with the nets usually being white and at least 45cm long.
The presence of the restricted area has changed how players, coaches, and referees approach the game. Offensively, players need to recognise when a defender is stationed in the restricted area, allowing them to drive confidently to the basket, knowing they will get a foul called on the defence if there is contact. Defensively, players should avoid the restricted area and try to get into a good defensive position sooner.
The restricted area is an important addition to the basketball court, prioritising player safety and fairness while also influencing offensive and defensive strategies.

Rule changes
The semicircle under a basketball net, also known as the restricted area, has been a part of professional basketball since 1997 and college basketball since 2012. This rule change was implemented to enhance player safety, make the game fairer, and simplify refereeing.
The restricted area is a semi-circular arc under the basketball hoop that extends four feet out from the centre of the hoop. It is also known as the 'no-charge zone' and its introduction has significantly impacted the way players approach the game on both offence and defence.
Before the introduction of the restricted area, defenders could remain near the basket, hoping to draw charges on any driving player, which often led to dangerous collisions. The restricted area was implemented to reduce these risks, giving offensive players more space and reducing the chances of collisions.
The main rule change regarding the restricted area is that defensive players positioned inside this area cannot draw offensive charging fouls when an offensive player is moving towards the hoop. A charging foul is an offensive foul that occurs when illegal contact is made by pushing, moving, or charging into a stationary defender. This rule change simplifies the game for referees, as they can automatically call a blocking foul on secondary defenders attempting to draw a charge within the restricted area.
Additionally, the restricted area has altered the way officials determine a charge call. Defenders must now be in a set position before the offensive player begins their jump, requiring earlier and more precise anticipation. This rule encourages offensive flow and prevents players from setting up permanently under the basket.
It is important to note that the rules regarding the restricted area may vary across different leagues and organisations. For example, in the NCAA, the restricted area rules differ between men's and women's basketball. As such, coaches and players must stay up-to-date with the specific rule changes in their respective leagues.

Player safety
The semicircle under a basketball net is known as the restricted area or the no-charge zone. This semi-circular arc is located under the basketball hoop and extends 4 feet out from the centre of the basket. It was introduced by the NBA during the 1997-1998 season to enhance player safety and make the game more uniform.
The primary purpose of the restricted area is to enhance player safety by reducing the risk of injury. Before the introduction of this rule, defensive players could position themselves very close to the basket, compromising the safety of offensive players trying to attack the basket and score. This often led to dangerous collisions, with offensive players having to brace for impact. The restricted area gives offensive players some space to operate without constantly worrying about collisions and provides them with a safe area to jump and land. This is especially important for young players learning the game, as it makes basketball camps safer.
The restricted area also helps prevent defenders from gaining an unfair advantage by sliding under an offensive player who has beaten their primary defender. This ensures fair play and maintains the integrity of the game by preventing defenders from taking advantage of their position.
Additionally, the restricted area makes it easier for referees to call charges, further contributing to player safety. The clearly defined semi-circle gives officials a distinct point of reference when making tough judgment calls between blocking fouls and charging fouls. This helps to reduce subjectivity in refereeing decisions and promotes fair play.
It's worth noting that the rules regarding the restricted area may vary slightly across different leagues and levels of basketball, such as in college basketball or women's basketball. Coaches and players should stay updated with the specific rule changes in their respective leagues.

Referees' calls
The semicircle under a basketball net is known as the restricted area or zone, 'the paint', or the 'no-charge zone'. It is a critical part of the basketball court that can decide the outcome of close games. This area was introduced to reduce the risk of dangerous collisions under the hoop and make the game safer. Before its introduction, defenders could stand near the basket, hoping to draw charges on any driving player, which often led to collisions.
The restricted area is a semi-circular arc located in the lane under the rim. It extends four feet out from the centre of the basket to the front edge of the backboard on both sides of the hoop. It is used to enhance player safety by limiting collisions between offensive and defensive players under the basket.
Referees play a crucial role in enforcing the rules related to the restricted area. They are responsible for ensuring player safety and maintaining fair play within this zone. Here are some specific calls and rulings that referees need to make regarding the restricted area:
- Blocking Foul: Any secondary defenders who attempt to draw a charge within the restricted area will automatically be called for a blocking foul by the referees. This rule simplifies the infamous block/charge call, which was previously more subjective and based on the referee's judgment.
- Offensive Fouls: According to NBA and college basketball rules, if a defensive player is inside the restricted area, an offensive player who makes contact with them cannot be called for a charging foul. This rule change was implemented to promote safety and fairness, reducing the likelihood of collisions near the basket.
- Three-Second Violation: Offensive players must be mindful of the restricted area's impact on their playing time in the lane. They can incur a three-second violation if they remain in the lane for more than three seconds without actively attempting to shoot, pass, or dribble. This rule encourages offensive movement and discourages players from establishing a permanent position under the basket.
- Legal Guarding Position: Referees should monitor defenders' movements to ensure they establish a legal guarding position outside the restricted area before an offensive player starts their jump. This rule change, implemented in men's college basketball, emphasises the importance of early and precise anticipation by defenders.
- Jump Balls: During jump balls, referees should ensure that non-jumpers remain outside the centre circle until one of the jumpers taps the ball. This rule applies to both the centre circle and the free-throw circle, which has a diameter of 12 feet.
- Fair Play and Safety: The restricted area rules aim to balance offence and defence, creating fairer calls and increasing safety for players. Referees should be aware of evolving rules across different leagues to make accurate calls, as rules may differ slightly between organisations like the NBA and NCAA.
By enforcing these rules, referees help to ensure that players utilise the restricted area strategically while prioritising safety and fair competition.

Offensive and defensive strategies
The semicircles under basketball nets are known as restricted areas or zones. They were introduced to enhance player safety by limiting collisions between offensive and defensive players under the basket. If a defensive player stands inside the restricted zone, an offensive player who makes contact with them cannot be called for a charging foul. This rule change was implemented to make the game safer, fairer, and easier to referee.
Offensive Strategies:
- Driving players need to recognize when a help defender is stationed in the restricted area. This allows them to drive confidently to the basket, knowing that they will at least get a free throw if there is any contact during the drive.
- Players should also be aware of the rules regarding fouls and the restricted area. For example, if a defensive player is inside the restricted area, an offensive player cannot be called for a charging foul if they make contact.
- Offensive players should also be aware of the positioning of their teammates and use different tactics to create decisive advantages in the game. For instance, they can use different sets of moves or pre-tactics, which are specific to certain players on the team.
Defensive Strategies:
- Defensive players should avoid the restricted area and focus on getting to a good defensive position sooner. By anticipating drives and positioning themselves out from under the rim, they can stop the ball and potentially draw a charge.
- The defender's task is to prevent the opponent from scoring by blocking and stealing the ball.
- There are different defensive strategies to choose from, such as man-on-man defense and zone defense. In man-on-man defense, each attacker is assigned an individual defender whose task is to make things difficult for that specific player. In zone defense, players focus on controlling a certain area, such as the space below the basket, rather than defending a single opponent.
- Defensive players should also be aware of the rules regarding fouls. For example, if a secondary defender attempts to draw a charge inside the restricted area, they will automatically be called for a blocking foul. However, a secondary defender can make contact with an offensive player inside the restricted area without committing a foul if they follow the principle of verticality by staying completely vertical and squared up to the offensive player.
