Boys ages 12–14. Women and girls ages 12 and up. This is the official size for women’s high school, college, and professional. A basketball is a spherical ball used in basketball games. Basketballs usually range in size from very small promotional items that are only a few inches (some centimeters) in diameter to extra large balls nearly 2 feet (60cm) in diameter used in training exercises. For example, a youth basketball could be 27 inches (69cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball would be a maximum of 30 inches (76cm) and an NCAA women's ball would be a maximum of 29 inches (74cm). The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75cm) in circumference and for the Women's National Basketball Association (WNBA), a maximum circumference of 29 inches (74cm). High school and junior leagues normally use NCAA, NBA or WNBA sized balls.

Basketball Australia to Play Ball with Spalding Through to 2019". Basketball Australia. August 10, 2016 . Retrieved 2018-02-02.On Wednesday, the NBA announced yet another change, but a subtler one. Starting in the 2021-22 season, Wilson will take over as the league's official ball manufacturer. Spalding currently holds the distinction. Fortunately for players and purists, the new ball will be made with the exact specifications of the current one, as the league revealed in its press release. Positions and responsibilities [ edit ] A diagram of the relative positions of basketball officials in "three-person" mechanics. The lead official (L) is normally along the baseline of the court. The trail official (T) takes up a position approximately level with the top of the three-point line. The center official (C) stands across the court near the free-throw line. In "three-person" mechanics, the court is further divided among three officials, with the lead (baseline) official determining the position of the other two officials. Normally, the lead official will move to the side of the court in which the ball is located (strong side), particularly if there is a "post-up" player in that position. The official that is on the same sideline as the lead official then takes up a position approximately level with the top of the three-point line and becomes the "trail" official, while the third official will stand across the court near the free-throw line in what is called the center position. This creates a triangle coverage of the court. Often, the lead will switch sides of the baseline during a play, requiring the trail to move down to be level with the free-throw line and become the new center, while the center will move up and become the trail. As the ball moves to the other end of the court in transition, the lead will become the trail, the trail will become the lead, and the center official will remain in the center (unless the new "lead" moves across the baseline to cover the strong side, in which case the center official and trail would then switch positions.) The 2022 NBA Play-In Tournament will take place April 12-15 (Tuesday – Friday), followed by the start of the 2022 NBA Playoffs on Saturday, April 16. TNT will present the 2022 Western Conference Finals and ESPN/ABC will present the 2022 Eastern Conference Finals. ABC will televise the NBA Finals 2022 presented by YouTube TV, marking its 20th consecutive season as the exclusive home of the league’s championship series. Game 1 of the NBA Finals is scheduled to be played on Thursday, June 2.

Six-time NBA All-Star Kyle Lowry of Miami, who played the previous nine seasons with the Raptors and helped the franchise win the NBA championship in the 2018-19 season, leads the Heat in a road game against Toronto on Thursday, Feb. 3 on TNT (7:30 p.m. ET). The matchup is the first of the Heat’s two road games against the Raptors this season. The officials must ensure that the game runs smoothly, and this encompasses a variety of different responsibilities, from calling the game to player and spectator management. They also carry a duty of care to the players they officiate and to ensure that the court and all equipment used is in a safe and usable condition. Should there be an issue that inhibits the safe playing of the game, then it is the job of the officials to rectify the problem. Quite often, the job of an official surpasses that of the game at hand, as they must overcome unforeseen situations that may or may not have an influence on the game.
