The basketball key, also known as the free throw lane or the restricted area, is a marked area on a basketball court surrounding the basket. The dimensions of the key have varied throughout the history of the game. In the NBA, the key is 16 feet wide, while in NCAA and NAIA basketball, it is 12 feet wide. FIBA-sanctioned tournaments used a trapezoidal key until 2010, with a width of 3.6 meters (12 feet) on the narrower end and 6 meters (20 feet) on the wider end. Following the 2010 FIBA World Championship, all FIBA-administered tournaments adopted a rectangular key with a width of 4.9 meters (16 feet), matching the width of the NBA key.

The key is 16 feet wide in the NBA
The key, also known as the free throw lane, is a marked area on a basketball court surrounding the basket, where a lot of the game's action takes place. The dimensions of the key have varied throughout the history of the game. In the NBA, the key is 16 feet wide. This is also the width of the key in FIBA-administered tournaments since the 2010 FIBA rule amendments.
The key is rectangular in shape in the NBA and WNBA, whereas in FIBA-sanctioned events, it used to be trapezoidal before it was changed to a rectangle as well. The width of the key in the NCAA and NAIA is 12 feet, and in high school basketball, it is 12 feet as well. The wider key in the NBA as compared to other leagues is due to the success of imposing centers like Wilt Chamberlain, who dominated the paint and scored at will. The key was widened to reduce the effectiveness of such dominant centers.
The intersection of the free throw line and the free throw lane is referred to as the elbow of the key. The lane lines have marks separating where players stand during a free throw attempt. The one nearest the basketball is marked wider than the others and is known as the block. The three-point line forms an imperfect arc stretching from one side of the baseline to the other. The arc isn’t a perfect circle because it would run out of bounds on the sides of the court.

It's 12 feet wide in the NCAA
The key, also known as the free throw lane, is a marked area on a basketball court surrounding the basket. It is where a lot of the game's action takes place. The dimensions of the key have changed over time and vary depending on the league and level of play. For example, the key in the NBA is 16 feet wide, whereas in U.S. college basketball, it is 12 feet wide.
In the NCAA, the key is 12 feet wide. This is in contrast to the NBA, where the key is 16 feet wide. The wider lane in the NBA is due to the success of tall centers like George Mikan and Wilt Chamberlain, who dominated the paint and scoring. The NCAA key is also wider than the original key, which was only six feet wide and shaped more like a keyhole. The key was widened to 12 feet at the start of the 1951-52 NBA season to counter the dominance of imposing centers.
The NCAA key is rectangular in shape, with a free-throw circle at its head or top. The first box on the side of the key is six feet from the baseline. The restricted area under the basket is three feet in diameter. The three-point line in the NCAA is also notably different from that of the NBA. It is only 20 feet, nine inches from the center of the basket, and because of the smaller diameter, it forms a continuous arc from one side of the baseline to the other without any straight lines.
The key is an important area of the basketball court, and players must follow certain rules when playing in this area. One such rule is the "three seconds rule," where a player on offense cannot stay in the key for more than three seconds without their team losing possession of the ball. Another rule is the lane violation, which occurs when a player enters the key before a free-throw shooter releases the ball.

The WNBA court size is the same as the NBA
The key, officially referred to as the free throw lane by the NBA, is a marked area on a basketball court surrounding the basket, where much of the game's action takes place. The width of the key in the NBA is 16 feet (4.9 meters), while in U.S. college (NCAA, NAIA, etc.) and high school (NFHS) play, it is 12 feet (3.7 meters).
The court dimensions of the Women's National Basketball Association (WNBA) are identical to the NBA court in every way except the three-point line. The three-point line in the WNBA is shorter at 22.15 feet (6.75 meters) in comparison to the NBA's 23 feet and 9 inches (7.24 meters). The distance from the three-point line in the WNBA is 22 feet at the top of the key and 21.75 feet in the corners. In the NBA, it is 23.75 feet from the basket at the top of the key and 22 feet from the basket at the corners.
The WNBA uses a slightly smaller basketball than the NBA. Women use a Size 6 ball weighing about 20 ounces, while the NBA uses a Size 7 ball weighing about 22 ounces.
Another difference between the two leagues is the game duration. In the NBA, a regulation game consists of 4 quarters, each lasting 12 minutes, resulting in a total game time of 48 minutes. In the WNBA, the game duration is slightly shorter, with each of the 4 quarters lasting 10 minutes, making the total game time 40 minutes.

FIBA-sanctioned tournaments used a trapezoidal key until 2010
The key, also known as the free throw lane or the restricted area, is a marked area on a basketball court surrounding the basket. It is where much of the game's action takes place. The dimensions of the key have varied throughout the history of the game. FIBA-sanctioned tournaments used a trapezoidal key from 1956 until 2010. The narrower end was on the free-throw line, measuring 3.6 metres (12 feet), while the wider end, at the end line, measured 6 metres (20 feet).
In 2008, FIBA approved rule amendments that would change the shape of the key in FIBA-sanctioned tournaments from trapezoidal to rectangular. These changes were implemented following the 2010 FIBA World Championship. The new rectangular key was 4.9 metres (16 feet) wide. This brought the shape of the key in FIBA-sanctioned tournaments in line with the rectangular shape used in American leagues, where the basketball court is measured in US units.
The change from a trapezoidal to a rectangular key in FIBA-sanctioned tournaments was not the first time the shape of the key had been altered. Originally, the key was narrower and shaped more like a keyhole, measuring just 1.8 metres (6 feet) wide. This gave imposing centres, such as George Mikan, a significant advantage, as they dominated the paint and scored at will. To counter this, the key was widened to 3.7 metres (12 feet) at the start of the 1951-52 NBA season.
The trapezoidal key was introduced in FIBA-sanctioned tournaments in 1956. It remained in use until 2010, when it was replaced by the rectangular key that is still in use today. This change brought the width of the key in FIBA-sanctioned tournaments in line with the width of the key in the NBA, which had been widened to 4.9 metres (16 feet) in the 1964-65 season to reduce the effectiveness of dominant centres, such as Wilt Chamberlain.

The key is also known as the 'lane' or 'the paint'
The area on a basketball court known as the key is officially referred to as the free throw lane by the NBA, NCAA, NAIA, NFHS, and the restricted area by the FIBA. Colloquially, it is also called the lane or the paint. The key is a marked area on a basketball court surrounding the basket, where a lot of the game's action takes place. The term "the key" comes from its original shape, which resembled a keyhole, with the free-throw circle as the head and the shaded lane as the body. The key's dimensions have varied throughout the history of the sport.
The key consists of what is colloquially known as the circle and the post, which also overlap at the bottom half of the circle. The post is bounded by the baseline, the free-throw line, and two lane lines connecting the free-throw line and baseline. The intersection of the free-throw line and the free-throw lane is referred to as the elbow of the key. The lane lines have marks that separate where players stand during a free-throw attempt. The one nearest the basketball is marked wider than the others and is known as the block.
The key is also sometimes referred to as the lane because it can be considered a lane showing the path to the basket. It is usually painted in a distinctive color. The dimensions of the key vary depending on the level of play and the governing body. In the NBA, the key is 16 feet wide, while in the NCAA and NAIA, it is 12 feet wide. The FIBA key is also 16 feet wide, but its courts are shorter and narrower than those of the NBA.
The width of the key has been changed multiple times to counter the dominance of imposing centers, such as George Mikan, who scored at will due to his height advantage. The key was widened to 12 feet in the 1951–52 NBA season and further widened to 16 feet in the 1964–65 NBA season to reduce the effectiveness of another dominant center, Wilt Chamberlain. The most commonly enforced rule regarding the key is the "three-seconds rule," where a player on offense cannot stay in the key for more than three seconds, or their team will lose possession of the ball.
