What are the ball’s diameter and circumference?
The size of the ball is different for men’s, women’s, and youth leagues.
For the NBA, men’s college, and boys ages 15 and up, players play with a 9.43-9.51 inch diameter (the width measured left to right) basketball. The ball’s circumference (the distance measured around the outside) is 29.5 inches. The official NBA game ball is made by Spalding and measures 9.43-9.51 inches in diameter or 29.5 inches (75cm) in circumference.
NCAA women and the WNBA use a slightly smaller ball with a roughly 9.07-9.23 inch diameter and 28.5-inch circumference.

Backboard, Baseline, and Key
The backboard is four feet from the baseline, marking the end of the players’ active playing surface.
The key is 16 feet wide and 19 feet from the foul line to the baseline.
Inside the key, a four-foot arc is designated to align with the center of the basket to mark the restricted arc. If a defender is within this arc, they cannot draw a charging foul.
Regulation backboards are six feet wide and 42 inches tall.
Free throw markings
Short lines are drawn three feet apart along both sides of the key area to designate the standing positions for rebounders when a free throw is being shot. The first line is drawn seven feet from the baseline.
A six-foot arc (half circle) starting from the free-throw line away from the basket completes the key area.
Core components of basketball courts
Baskets, free-throw lines, three-point arcs, and the half-court line are some of basketball courts’ foundational elements. Court lines mark 94 feet in length by 50 feet in width for NBA courts. The half-court line is at 47 feet. Indoor courts are frequently made of hardwood-like polished maple. Outdoor courts may be composed of asphalt, concrete, or other pavements.
The words baseline and end line both refer to the ends of the court running behind the goals.
In the middle of the half-court line is a tip-off circle that has a six-foot radius. This is where the opening jump ball takes place.
The backcourt refers to the half of the court where the team’s basket is defended. The boundary lines include their end line, sidelines, and the half-court line of the playing court.
For international play, the standard court size is 28m long and 15m wide, measured from the inner edge of the boundary line.
