Everything you Need to Know About Basketball Court Dimensions

Have you ever wondered why some basketball courts are larger than others? Do you notice all the markings on the floor and wonder what they mean? Whether you’re a hoop aficionado or a budding baller, it is always beneficial to learn about the unique sizes of different basketball courts at various levels. In this blog post, we will delve into the key dimensions and markings of some of the most prestigious basketball leagues around the world.

NBA Basketball Court Dimensions

The National Basketball Association, better known as the NBA, boasts the largest court dimensions of any level of basketball — domestic or international. 

  • Basketball Court Length: 94 feet
  • Basketball Court Width: 50 feet
  • Rim Height: 10 feet
  • Center Circle Diameter: 12 feet
  • 3-Point Line: 23.75 feet at the top and 22 feet in the corner
  • Key: 19 feet from baseline and 16 feet wide

WNBA Basketball Court Dimensions

The Women’s National Basketball Association or WNBA’s court dimensions are identical to the NBA court in every way except the three-point line. Instead, the three-point line is 22.15 feet from the center of the hoop. WNBA teams share arenas and playing surfaces with the NBA, which is why it’s no wonder the court dimensions are so similar.

NCAA Basketball Court Dimensions

National Collegiate Athletic Association or NCAA basketball courts have similar dimensions to the NBA and WNBA. 

That said, there are a few significant differences in the dimensions of the NCAA court. For starters, the key is only 12 feet wide, rather than 16. The first box on the side of the key is only six feet from the baseline, not seven. The restricted area under the basket is also one foot smaller, at three feet in diameter rather than the NBA’s four.

However, the most recognizable difference between the NBA’s court dimensions and the NCAA’s is the distance of the three-point line. The NCAA three-point line is only 20 feet, nine inches from the center of the basket. Because of the smaller diameter, it is a continuous arc from one side of the baseline to the other, with no straight lines necessary to create space on the sidelines. The difference in three-point line distances is the biggest adjustment for shooters to make as they begin their professional careers, and also why it’s so difficult to project how well a player will shoot in the pros.

High School Basketball Court Dimensions

High school basketball courts are a little different from their college and professional counterparts. The most noticeable difference is that the court is a full 10 feet shorter, measuring only 84 feet. However, there are some similarities. The court is still 50 feet wide. The basket is also 10 feet off the ground.

The tip-off circle has a six-foot radius, just like the big kid courts, and while the high school landscape isn’t as standardized as college and professional basketball, the backboard is supposed to have the same measurements as the NCAA and NBA.

Just as in college and professional basketball, the foul line is 15 feet from the backboard, and the key is 19 feet long. It’s also the same 12 feet wide as the NCAA — four feet narrower than the NBA and WNBA.

The other visible difference is the distance from the three-point line. Shorter than either the NCAA or NBA, the high school free throw line is just 19 feet, nine inches from the center of the basket. Additionally, high school basketball courts do not have any restricted area under the basket, since that rule doesn’t exist in high school basketball.

FIBA Basketball Court Dimensions

FIBA governs international basketball courts. The measurements for FIBA basketball courts differ from U.S. courts because of the difference between our Imperial measurements — feet and inches — and the more standard metric system.

FIBA courts are even 28 meters long, which converts to almost 92 feet. The 15-meter width converts to just over 49 feet. The tip-off circle is a bit smaller as well, at 3.5 meters in diameter. This difference translates to a radius of about five feet, seven inches.

The key is almost the same size at 5.8 meters long and 4.8 meters wide. These numbers convert to within a few inches of 19 and 16 feet. The basket is 1.2 meters, or almost four feet, in from the baseline, which puts the foul line at 4.6 meters — 15 feet — away. The restricted area under the basket is 1.25 meters or just a shade more than four feet in radius.

The basket is still 10 feet off the ground, which means the biggest difference is the three-point line. At the top of the arc, the three-point line is 6.75 meters from the center of the basket or 22.15 feet.
