Introduction to Basketball – Rules, Positions and How to Play 

Basketball, invented in 1891  by  Dr. James Naismith, is one of the most popular sports on the planet.

Understanding the rules of basketball is crucial as it promises fair lay and increases the enjoyment of the game for players, coaches and fans. The game is played by two teams, consisting of 5 players on the court at any given time, with additional players on the bench.

According to the International Basketball Federation (FIBA), court dimensions are 28m x 15m. The National Basketball Association (NBA) court is  slightly bigger at 28.7m by 15.2m or 94ft by 50ft  

The court has lines and markings which include baseline, sideline, free-throw line, three-point line, and the center circle. These lines define the boundaries and various zones of play. 

The basketball is 29.5" for men and 28.5" for women and youth players aged 9-12. On the court, it is also essential to have a backboard, the hoop and the net.

    1. Defensive Rules

    The team on defense is the team without the basketball. The main defensive rule is to play  within the bounds of fair defense, avoiding illegal contact and other fouls.
