Rules of basketball

The rules of basketball are the guidelines that help everyone play fairly and safely. These rules tell us how to play the game, what equipment we can use, and what the referees do.

In North America, groups like the National Basketball Association and the NCAA make their own special rules for their games. Outside of North America, most places follow the rules from the Technical Commission of the International Basketball Federation, known as FIBA. These rules help make sure basketball games are fun and fair for everyone, no matter where they are.

Original rules

On 15 January 1892, James Naismith shared his rules for a game he called "Basket Ball." Back then, the game looked very different from today.

Here are a few of the original rules:

1. Players could throw the ball in any direction using one or both hands.
2. The ball could also be hit with the hands, but not with a fist.
3. Players couldn’t run with the ball; they had to throw it from where they caught it.
4. The ball had to be held properly in the hands, not with the arms or body.
5. Pushing, holding, or hitting an opponent wasn’t allowed. The first time someone did this it counted as a foul. Doing it a second time meant they had to sit out until the other team scored.
6. Certain actions, like hitting the ball with a fist, were also fouls.
7. If a team made three fouls in a row, the other team got a point.
8. A goal counted when the ball was thrown into the basket and stayed there, as long as the other team didn’t touch it.
9. If the ball went out of bounds, the person who first touched it after it was thrown back in got to keep it. They had five seconds to throw it back in, or it went to the other team.
10. There were two halves of fifteen minutes each, with a five-minute break in between.
11. The team with the most points at the end won. If it was tied, they could keep playing until one team scored another point.

Naismith’s original rules are very valuable and are shown at Allen Fieldhouse on the campus of the University of Kansas. He was the first coach of the Kansas Jayhawks men's basketball team.

Players, substitutes, teams and teammates

In the early days of basketball, there were no rules about how many players could be on the court. By 1900, it became standard to have five players on the court at a time. At first, players who were taken out of the game could not return, but this rule changed over time. By 1945, players could come back into the game as many times as they wanted.

At first, coaches were not allowed to talk to their players during a game, but this changed in 1949. Coaches could then speak to their players during timeouts. Also, players used to be removed from the game after making a certain number of mistakes, called fouls. The number of fouls needed to remove a player changed several times. Today, in most basketball games that last 40 minutes, a player is removed after five fouls. In longer games, like those in the National Basketball Association, a player is removed after six fouls.

Shot clock and time limits

Basketball has rules to keep the game moving. In 1933, a rule was made that teams had to move the ball across the center line within ten seconds after getting it.

Teams also have only 5 seconds to put the ball back into play when they are passing it to a teammate. There is a rule called the three-second rule that stops players from standing too close to the basket for more than three seconds.

The shot clock, introduced in 1954, requires teams to try to score within a certain time after getting the ball. These rules help make basketball fast and exciting.

Fouls, free throws and violations

Basketball has rules about fouls and how to handle them. One rule is about dribbling. It was added in 1901. At first, players could only bounce the ball once before shooting. By 1909, the rules changed so players could bounce more times and still shoot.

Another rule is about running with the ball. In 1922, this stopped being a foul and became a violation. This means the team loses the ball but no other penalty happens. There are also rules about striking the ball with a fist, which is also a violation.

Free throws are shots taken from a specific spot on the court after a foul. They were added shortly after basketball was invented. The line for free throws was moved closer to the basket in 1895. If a player is fouled while trying to score, they get one or more free throws depending on the situation and the league rules.

Different leagues have different rules for free throws after fouls. For example, in NCAA men's basketball, the number of free throws depends on how many fouls the team has made. In the NBA and WNBA, players get two free throws after a certain number of team fouls. These rules help keep the game fair and exciting.

Equipment

Basketball started with a regular soccer ball, but now it has its own special ball. The goal, called a hoop, is placed 10 feet above the court. Instead of a basket that needed cleaning after each shot, we now use a hoop with a net that catches the ball.

In men's leagues like the NBA and college basketball, they use a size seven ball that is 29.5 inches around. In women's leagues like the WNBA and college basketball, they use a size six ball that is a bit smaller, at 28.5 inches around.

Officiating and procedures

Main article: Official (basketball)

Basketball has special rules to make sure games are fair. In the past, one person watched for rule breaks and another watched the ball. Now, all officials can manage the game the same way. The NBA added a third official in 1988, and other groups did this later too.

Some rules have changed to make the game better. For example, after a score, the team that did not score gets the ball instead of jumping to start. There are also rules for when time is running out and for solving arguments about calls. These rules help make every game fair and smooth.

International rules of basketball

The latest international rules for basketball were approved on February 2, 2014, by FIBA. They started on October 1 that year.

There are eight main rules with 50 articles. They cover topics such as equipment, teams, players, coaches, how to play, mistakes players can make, and what happens when the rules are broken. The rules also include signals for referees, how to fill out score sheets, and other important details.
