Zones inside an indoor basketball court

Basketball court Sidelines

The outer edge of the court is determined by the sidelines, which run the length of the court. On a full-sized court they measure 28m or 94 feet

Basketball court Baseline and endline

The terms baseline and endline both refer to the ends of the court running behind the goals. Typically they measure 15m.

The use of the different terms depends on the direction a team is playing. Endline is the term for the end of the court which a team is defending, baseline is the for the attacking end.

Mid court

This is the halfway mark on the court and is used to denote the offensive playing area during a game.

On a full-sized court, the mid court line would be 14m from each endline.

Basketball Centre circle dimension

Used for the opening tip off, the centre circle has a 12 feet or 3.6m diameter.

Three point line

The three point lines are the arcs that mark a range boundary from each hoop. Scoring from outside this line is worth three points. The distance of the line will vary depending on the level of game, but is typically 6.75m from the basket.

Free throw line

The free throw line, marked 4.6m from the backboard, is the mark at which a player must stand when shooting free throws.

Free throw circle

The free throw circle is the same size as the centre circle (3.6m in diameter). Shooters must stay inside this circle when taking a free throw. The circle is also used for jump balls.

Free throw lane lines/key

Lane lines run from the free throw line to the baseline, to form the ‘key’. The shape and width can vary depending on the level of the game, but FIBA (International Basketball Federation) regulation changes in 2010 set it as a 4.9m by 5.8m rectangle.

Some also include space markings to keep opposing players from obstructing the free throw shooter.
