To understand basketball, it’s important to have an idea of the court’s layout.
According to FIBA (international basketball federation) guidelines, a basketball court is a rectangular playing area 28m in length and 15m in width. International competitions including the Olympics follow FIBA guidelines.
The border markings along the length of the court are called sidelines and the breadth of the court are called endlines or baselines.
The outer edge of the key parallel to the endline is called the free-throw line. There’s a 3.6m diameter semi-circle drawn on the outer part of the free-throw line called the free-throw circle.
