Know the accurate Basketball Rules and Regulation

Rules and Regulation

The Size of A Basketball Court 

Well, the size of a basketball court is dependent on the league rules being played. For instance, the size of a high school basketball court is 84 feet by 50 feet. On the other hand, an NBA or college basketball court is 94 feet by 50 feet.

But when it is an international basketball governed by FIBA, the size of the court is 92 feet by 49 feet. Many youth basketballs play on a court that is 74 feet by 42 feet.

The Size of A Basketball

In the modern game, most basketballs are assigned a specific size. Such as the men’s official basketball size (for NBA, college, and high school sports) is a size 7. Wait, what does size 7 mean?

Well, it means the basketball is 75-76 centimeters in circumference. Quite the contrary, women play with a size 6 ball at all levels which means, the basketball is 72-74 centimeters in diameter.

Maximum youth basketball is a size 5, which is 69-71 centimeters in diameter whereas K-2 leagues use a size 3 ball, which is 56-57 centimeters in diameter.

Basketball Jersey Numbers That Are Allowed 

Generally, professional basketball leagues allow any number to be placed on a player’s jersey.

But, in high school, college, or youth basketball leagues, nothing but single or double digits up to the number of 5 are allowed to be on a jersey (including a 0 or 00). From 1-5, 10-15, 20-25, 30-35, 40-45, or 50-55 jerseys are considered permissible.

This rule is for the non-professional games because it offers more accurate communication between the referee and the scorer’s table. Generally, the referee uses his hands and indicates the player number for a foul committed as if it can be accurately logged.

How Many Fouls Will Be Allowed in Basketball?

At the high school and collegiate levels, standard basketball rules allow for 5 fouls. But players in the NBA  (National Basketball Association) or WNBA (Women’s National Basketball Association) are generally allowed 6 fouls unless an exhibition game with different rules is being played.

Some of the youth leagues allow 6-10 fouls per player, with the intention of never having a player foul out of the game since the goal is to help them learn the fundamentals of basketball.

Technical fouls are quite different. Before ejection, players are allowed 1-2 technical fouls (depending on the severity of the infraction). In case, a technical foul doesn’t lead to an ejection, it will count as a personal foul.

Some leagues are used to tracking technical foul numbers over the course of a season and then implement suspensions on specific numbers. In the NBA, if anyone accumulates 16 unsportsmanlike technical fouls over the course of a season, it results in a one-game suspension.

Duration of A Basketball Game

Youth leagues generally have quarters that are 6 to 8 minutes in length. Most of the high school basketball games operate with 8-minute quarters (creating a 32-minute game).

Collegiate games usually feature two 20-minute halves for a 40-minute game. NBA games feature 12 minute quarters whereas WNBA features 10-minute quarters.

The Size of A Basketball Hoop

Starting with the standard basketball hoop size, it is 18 inches in diameter. Moreover, the hoop is attached to a backboard at a height of 10 feet from the ground. The size of the inner rectangle on the backboard is 24 inches wide by 18 inches tall.

About the regulation backboards, the size is 72 inches wide by 42 inches tall. For youth leagues, the only difference thing is the rim height. For grades 3-4, 8-foot rims are recommended whereas, for grades 5-6, 9-foot rims should be used. Kids in K-2 should use 7-foot rims.

The Number of Players on A Basketball Team

According to the standard rules, a basketball game is a five-on-five experience. Team members can have any number of substitutes on the bench, ready to enter the game if they are called upon by the coach.

Most teams are used to having a rotation of 7-9 players that will play frequently, with 2-3 additional reverse (in case, players are ejected/get into early foul trouble).

What Are Team Fouls?

According to the modern game of basketball, team fouls are the sum of total fouls committed by each player on a team. When a team commits enough fouls, it leads to bonus free-throw opportunities for the other team.

In US high school and college basketball, if a team commits 7 fouls in half, the opposing team can shoot one-and-one free throws. Once they make a first free throw, a second is awarded. But if they miss the first free throw, then the game continues on. At more than 10 fouls in a half, the opposing team gets awarded two free throws.

In the NBA, each of the teams is allowed to commit 4 fouls in a quarter (without a penalty). On the 5th team foul, the team will be considered to be in a ‘penalty’ situation. Besides, more than one foul that committed in the last two minutes of a quarter will qualify for the penalty situation.
