Basketball Court Dimensions

Basketball is a popular sport that millions of people across the world participate in and love. Understanding the measurements of a basketball court is vital, whether you’re a professional player, a casual fan, or simply a curious observer. In this post, we will look at basketball court measurements such as size, length, breadth, and the many types of courts.

Basketball Court Dimensions 


Basketball court size has a significant influence on gameplay and the entire experience of the sport. The conventional basketball court size varies between leagues and organizations. However, the dimensions established by the National Basketball Association (NBA) and the International Basketball Federation (FIBA) are the most frequently accepted.

Basketball Court Dimensions in Feet

The official dimensions of a basketball court, as defined by the NBA and FIBA, are as follows:

  • Length: The length of a basketball court is 94 feet (28.65 meters) for both NBA and FIBA regulations.
  • Width: The width of a basketball court varies depending on the league. For the NBA, the width is 50 feet (15.24 meters), while FIBA regulations specify a width of 49.21 feet (15 meters).

These dimensions ensure a standardized playing area and allow players to showcase their skills within a defined space.

Basketball Court Sizes

Court TypeDimensions (Length x Width)
Half CourtVaries (Half the size of a full court)
Mini CourtVaries (Smaller than a half court)
Full Court94 feet by 50 feet (standard dimensions)

While the standard court dimensions mentioned earlier are commonly used, it’s worth noting that basketball courts can vary in size, especially in non-professional settings. Some recreational courts may be smaller or larger than the standard dimensions due to space constraints or local preferences.

  • Half Court: A half court is exactly what it sounds like: a basketball court half the size of a full court. Half courts are typically seen in parks, community centers, and residential neighborhoods.
  • Mini Court: Mini courts are even smaller than half courts and are intended for younger players or those with limited room. These courts are ideal for novices to learn and enjoy the game.
  • Full Court: Full-sized basketball courts are the usual dimensions used in professional leagues and international championships. These courts provide adequate space for participants to display their abilities and engage in fast-paced gaming.

Basketball Court Length in meters

The length of a basketball court, as mentioned earlier, is 94 feet (28.65 meters) for both NBA and FIBA regulations. This length includes the playing area from baseline to baseline and does not incorporate any additional space beyond the boundary lines.

Basketball Court Width

The width of a basketball court varies between the NBA and FIBA regulations. For the NBA, the width is 50 feet (15.24 meters), while FIBA specifies a width of 49.21 feet (15 meters). The width measurement is taken between the sideline boundaries and includes the playing area, from one sideline to the other.

Outdoor Basketball Court

Outdoor basketball courts are popular leisure locations where players can enjoy the game outside. Parks, schoolyards, and community centers are common locations for these courts. Outdoor basketball courts can vary in size, although they usually conform to the conventional size or are scaled down to fit space constraints.

Basketball Court Lines

Basketball court lines play a crucial role in regulating gameplay and defining different areas of the court. Here are some important lines found on a basketball court:

  • Baseline: The baseline is the boundary line that extends behind each basket. It marks the end of the court and is used for inbound passes and out-of-bounds situations.
  • Sidelines: The sidelines run the length of the court, parallel to each other. They define the width of the playing area and mark the boundary for inbound passes and out-of-bounds situations on the sides of the court.
  • Three-Point Line: The three-point line, also known as the arc or the perimeter, determines the area from which a player can score three points by shooting the ball into the basket. The distance from the three-point line varies between different leagues and levels of play.
  • Free-Throw Line: The free-throw line is located 15 feet (4.57 meters) from the backboard. It is used for free-throw shots, awarded to a player after a foul by the opposing team.

Basketball Half Court Dimensions 


The official half-court dimensions for basketball are as follows:

  • Baseline: 50 feet
  • Sideline: 47 feet
  • Free Throw Line: 15 feet from the baseline
  • 3-Point Line: 23 feet 9 inches from the baseline in the NBA and FIBA, and 22 feet from the baseline in high school.

These dimensions are the same for both men’s and women’s basketball.

In some cases, half-courts may be smaller than the official dimensions. For example, a backyard half-court may be 30 feet by 30 feet, which is still large enough to play a game of basketball.

Here is a table that summarizes the official half-court dimensions in feet and meters:

There is a 15-foot lane (also known as the key or the paint) on each half of the court, extending from the free throw line to the basket. The free throw line is 15 feet from the front of the backboard and 18 feet, 10 inches from the baseline.
