The dimensions of an international standard basketball court, as established by the International Basketball Federation (FIBA), are 28 meters in length and 15 meters in width. These dimensions are applicable for international competitions, which include events like the Olympic Games and the FIBA Basketball World Cup. The measurements are taken from the inner edge of the boundary lines, ensuring uniformity across all venues. Additionally, the lines marking the court are 5 centimeters wide, contributing to the clarity and precision required during play. This standardized size ensures that athletes compete on a fair and consistent platform, supporting the integrity of the competition.

In contrast to FIBA standards, the National Basketball Association (NBA) in the United States uses courts that are slightly larger, measuring 28.65 meters in length and 15.24 meters in width. Although the size differs, both NBA and FIBA courts share a similar basic layout, including markings such as center lines and three-point arcs. The slight increase in dimensions for NBA courts does not significantly alter the fundamental structure of the playing area.
