The following are thorough descriptions of the main parts of a basketball court, along with their purposes.
1. The Central Circle
The game begins with a tip-off from the center circle. The circle’s circumference varies slightly depending on the regulating organization.
NBA: 12 feet (3.66 metres)
FIBA: 11.81 feet (3.6 m)
The tip-off occurs in the center circle, where the referee throws the ball up and players jump to gain possession.
2. The Three Point Line
The three-point line goes around the basket. Any shot taken beyond this line earns three points. The distance between the line and the basket varies.
NBA: 23.75 feet (7.24 meters) at the arc and 22 feet (6.7 meters) at the corners.
FIBA: The arc is 22.15 feet (6.75 meters) long, and the corners are 21.65 feet (6.6 meters).
High school: 19.75 feet (6.02 meters).
3. The Key (Paint Area)
The rectangular region beneath the basket is where the key, often known as “the paint,” is located. This zone is vital for offensive and defensive plays since it is extensively monitored.
NBA dimensions: 16 feet wide.
FIBA dimensions: 16.08 feet wide.
High School is 12 feet wide.
4. The free throw line
Following a foul, players shoot unchallenged at the free-throw line. Most standards specify 15 feet from the backboard. The line is a primary focus in both practice and games.
5. Restricted Area Arc
The restricted area arc is a semi-circle situated beneath the basket. Defensive players within this arc cannot draw charging fouls.
NBA: 4 feet (1.22 meters) radius.
FIBA: Similar measurements.
6. Sideline and Baseline
The sidelines mark the court’s length, while the baselines mark its breadth. These limits define the play area:
NBA: 94 feet by 50 ft.
FIBA dimensions: 91.86 feet by 49.21 feet.
High School is 84 feet by 50 feet.
Specialized Court Markings
Half Court Line
The half-court line separates the court into two equal parts. In the NBA, teams must advance the ball past this line in eight seconds, but in high school and college, they must do so in 10.
Team Bench and Scorers’ Table
The sides around the center court frequently house team benches and the scorers’ table, where timekeepers and officials oversee the game.
Outdoor and recreational basketball courts
While professional courts have strict dimensions, outdoor and recreational courts may differ:
- Court sizes can range from half-courts to full-courts, depending on available space.
- Materials: Outdoor courts are often composed of asphalt or concrete.
- Customizations: Some recreational courts have unique color schemes or additional lines for different sports.

Three-point lines are changed to reflect player skill levels and the game’s regulatory body. Professional leagues, like as the NBA, have longer fields than high school courts.
3. What’s the difference between backboards and baskets?
All leagues use the same dimensions for backboards (6 feet wide and 3.5 feet tall) and baskets (18 inches in diameter). However, the materials used for outdoor courts may differ.
4. What is the length of the three-point line?
The distance between the three-point line varies by league:
NBA: 23.75 feet at the arc, 22 feet in the corners.
FIBA dimensions: 22.15 feet at the arc, 21.65 feet at the corners.
High school height is 19.75 feet.
5. What is the limited area’s arc?
The restricted area arc is a semi-circle beneath the hoop where defensive players are unable to draw charging fouls. The NBA and FIBA use a radius of four feet.
6. Why do court sizes vary among leagues?
Court sizes are changed to match the skill level and physical abilities of the players. Professional leagues such as the NBA use wider courts to allow faster-paced action.
7. What materials are utilized in basketball courts?
