23 feet 9 inches in height The distance from the basket to the three-point line varies by competition level: in the NBA, the arc is 23 feet 9 inches (7.24 m) from the hoop; in FIBA, the WNBA, and men's play in both the NCAA (all divisions) and NAIA, the arc is 6.75 m (22 ft 1.75 in); and in NCAA d3 and NAIA college basketball, the line is 10 feet (3 m).
The number was originally 25 feet until 1979 when it was changed to accommodate an increase in the number of games in a season. Previously, there had been only 50 games played in the entire history of the NBA.
In addition, there is no set amount of time that each game has to end. If a game goes into overtime, then it can last as long as needed to determine a winner. In fact, all playoff games go to at least one overtime period. The first ever NBA playoff game ended in a tie game with just under two minutes left in regulation time of the first round match up between the Boston Celtics and the Philadelphia Warriors. There were only six people in the audience for this game that took place on April 19, 1948. Since then, hundreds of games have gone into overtime during the playoffs.
The Golden State Warriors are the most recent team to win their first game in an overtime period. They did so against the New Orleans Pelicans on May 11, 2015.
23 feet 9 inches tall The arc is generally 23 feet, 9 inches long, however it is not consistent. The distance between it and the basket in the corners is barely 22 feet. The NBA opted to redesign the arcs such that they were all 22 feet distant from the hoop. The outcomes exceeded the NBA's wildest hopes in certain respects. The ball moved faster, the players were able to get into a shooting position earlier, and they made more three-pointers. At first, some people doubted that making the arc smaller would result in more three-pointers being made. However, research has shown that the number of three-pointers made increased by about 7% while the percentage of shots taken at the rim decreased by about 4%.
The shorter arc allows for more offense down low. Before the change, only 20% of NBA games ended with a shot taken near the basket. After the change, that number rose to 28%. More free throws were taken after the change was implemented because there were more opportunities to shoot them.
Another advantage of the new design is that it makes basketball more accessible for fans of different heights. Before the change, most courts were designed with baskets that were too high for most adults to reach. This prevented many people from seeing basketball games live. Now that every court is equal, anyone can go to an arena anywhere in the world and feel comfortable watching the game.
Finally, having a shorter arc means that there are more three-point shots per game.
22 feet The Three-Point Line (Arc): Three-point lines differ in the following ways: Basketball Courts in the NBA: On the sides, the 3 point arc measures 22 feet to the center of the hoop, with a straight line stretching out 16 feet 9 inches from the baseline. The line stretches out 23 feet 9 inches from the middle of the rim after those points. College Basketball Courts in the NCAA: On the side lines, the 3 point arc measures 20 feet 8 inches to the center of the hoop, with a straight line extending 17 feet 10 inches from the baseline. The line extends 18 feet 10 inches from the middle of the rim.
Basketballs are made of rubber and have a circumference of 19 inches. To make it easier for players to shoot free throws, each corner of the foul lane is marked by a small raised circle called a "foul peg." There are two foul pegs; one is placed 4 feet 9 inches from the basket and the other 2 feet 6 inches from the first. A referee monitors play during games and can award 1 point for a shot made from within the 3 point line or 2 points if the shot comes from beyond the line.
In addition to winning games, referees also affect the outcome of games by making calls on defense and offense. For example, if a team is running an Ionic motion offense and draws up a play for themselves, they will often call for the ball handler to get the ball inside the arc before crossing half court.
