Basketball is a sport with a lot of rules and specific court markings. One of the most important lines on a basketball court is the foul line, also known as the free-throw line, where a player stands when taking a foul shot. The foul line is located within the three-point arc, and its distance from the backboard is an important factor in the game. So, how far is it from the backboard to the foul line?
| Characteristics | Values |
|---|---|
| Foul line distance | 15 feet from the foul line to the front of the backboard |
| 18 feet 10 inches from the baseline | |
| Distance from the three-point line | 22 feet, 2 inches or 6.75 meters from the center of the basket |
| The key | 16 feet wide for NBA and FIBA |
| 12 feet wide for College, High School, and Junior High play | |
| 19 feet long |

What You'll Learn

The foul line is 15 feet from the backboard
The foul line in basketball is 15 feet from the backboard. This distance is the same across NBA, WNBA, FIBA, NCAA, high school, and junior high school courts. The only variation in the layout and dimensions of these courts is in the overall court size and the three-point line.
The free-throw line, where players stand to take a foul shot, is located within the three-point arc. A foul shot is worth 1 point, but if a shot is made from the foul line during play, it is worth 2 points. The three-point arc refers to the line that separates the two-point area from the three-point area. A basket made from behind this arc is worth 3 points, while a basket made from within this line or with a player's foot touching the line is worth 2 points.
The key, free throw lane, or shaded lane refers to the usually painted area beneath the basket. For the NBA, it is 16 feet wide, while for FIBA tournaments, it is wider at 19 feet. The key is used to prevent players from staying beneath the basket of the opposing team for long periods (a maximum of three seconds). The free throw lane is the hub of the action in each half-court.
The basketball court is a symmetrical space, with one half being a mirror image of the other. The entire court is 94 feet by 50 feet. On each half-court, there are painted lines that show the free throw lane and circle, as well as the three-point arc. The distance of the three-point arc from the basket varies depending on the level of hoops being played.

The key is 19 feet long
The key, also known as the free throw lane, the shaded lane, or "the paint", is a marked area on a basketball court surrounding the basket, where much of the game's action takes place. The key is 19 feet long and 16 feet wide for NBA and FIBA-administered tournaments, and 12 feet wide for college, high school, and junior high play. The free throw lane is the hub of the action in each half-court.
The key was originally narrower and shaped more like a keyhole, with the free-throw circle as the head and the shaded lane as the body, which is why it is called "the key". In the 1951–52 NBA season, the key was widened to 12 feet to prevent imposing centers from dominating the paint. In the 1964–65 NBA season, the key was widened further to 16 feet to reduce the effectiveness of dominant centers, especially Wilt Chamberlain.
The free throw line, where players stand while taking a foul shot, is located within the three-point arc at 15 feet from the plane of the backboard. The basket is 1.2 meters, or almost four feet, in from the baseline, which puts the foul line at 4.6 meters, or 15 feet, away. The restricted area under the basket is 1.25 meters, or just over four feet, in radius. The basket is 10 feet off the ground.
The three-point line varies depending on the level of basketball being played. In the NBA, the three-point line ranges from 22 feet in the corners to 23.75 feet behind the top of the key. FIBA and NCAA both adopted the three-point line in 1986. Most high school associations in the USA have a distance of 19.75 feet.

The three-point line varies by league
The three-point line in basketball varies depending on the league. The distance from the basket to the three-point line differs according to the level of basketball being played.
In the National Basketball Association (NBA), the three-point line is 23 feet 9 inches (7.24 meters) from the center of the basket and 22 feet (6.71 meters) in the corners. The NBA first introduced the three-point line in the 1979-80 season, and it has remained at the same distance since.
In the Women's National Basketball Association (WNBA), the three-point line is 22.15 feet (6.75 meters) from the center of the basket, which is the same distance used in the International Basketball Federation (FIBA) format. The WNBA and FIBA lines are over a foot and a half closer than the NBA line.
The National Collegiate Athletic Association (NCAA) also uses the 6.75-meter (22 feet 1.75 inches) three-point line. This distance was introduced in 2019, marking a significant change from the previous distance of 20 feet 9 inches.
At the high school level, the three-point line is even closer to the basket, with a distance of 19 feet 9 inches (6.02 meters) in the National Federation of State High School Associations (NFHS).
The varying three-point lines across different leagues add excitement and strategic depth to the game, providing unique challenges and opportunities for players and teams to adapt their playing styles accordingly.

The three-second rule
There is also a defensive three-second rule, which applies to defensive players who remain in the paint without actively guarding an opponent. This rule is designed to prevent defenders from "camping" under the hoop and disrupting offensive flow. The defensive three-second rule is only enforced in the NBA and begins when a defensive player has one foot in the paint and is not within arm's reach of an offensive player.
