Start here: 9 main parts 9

  1. Sideline One of the two long boundary lines. On an NBA court they are 94 feet long.
  2. Baseline (end line) The boundary line at each end of the court, usually 50 feet. Inbounds passes after a made basket are taken from it.
  3. Half-court line (midcourt line) The line across the middle that splits the court into two halves.
  4. Center circle The circle at midcourt, 12 feet across on an NBA court. Only the two players jumping may be inside it before the opening tip.
  5. Three-point line (arc) A basket made from beyond it is worth three points. In the NBA it is 23.75 feet from the basket, 22 feet in the corners; most US high schools use 19.75 feet.
  6. Key (lane, the paint) The shaded area under the basket, 16 feet wide in the NBA. An attacking player may not stay in it for more than three seconds.
  7. Free-throw line (foul line) Where a player stands to take a foul shot. It is 15 feet from the backboard. A made free throw is worth one point.
  8. Backboard The flat board the basket is fixed to. The free-throw distance is measured from it.
  9. Basket (rim) The hoop and net, always 10 feet above the floor by rule. Youth play may lower it.

Lines and marks: 8 2

  1. Coaching box Two lines mark how far along the sideline a coach may stand. They are 28 feet from each end line. The team bench is behind.
  2. Substitution area Where substitutes wait to come on. Two lines beside the half-court line, outside the court, mark it. Off-court officials like the timekeeper sit behind.

Under the basket: 6 3

  1. Top of the key The half of the free-throw circle outside the lane. The round top of the key. The NBA three-point line is 23.75 feet away behind it.
  2. No-charge arc (restricted area) A defender standing inside it cannot draw a charging foul. A half circle 4 feet from the middle of the basket in the NBA, NCAA men's play and WNBA.
  3. Lower defensive box Marked on NBA floors by two hash marks. They sit on the end line beside the key. A defender may draw a charge inside the arc if the attacker got the ball or began the drive in the box.

How this list was compiled: Read 2026-09-26: Wikipedia, Basketball court, https://en.wikipedia.org/wiki/Basketball_court : the NBA court 94 by 50 feet and FIBA 28 by 15 m; older high school gyms 84 or 74 feet long; baskets 10 feet above the floor except possibly in youth play; the three-point line (NBA 23.75 feet, 22 feet in the corners; US high schools 19.75 feet); the free-throw line 15 feet from the backboard's plane, a foul shot worth one point; the key, free-throw lane or shaded lane, 16 feet wide in the NBA, and the three-second limit; the no-charge zone arc of 4 feet in the NBA, NCAA men's and WNBA; the center circle 12 feet across and the jump ball; the baseline or end line, usually 50 feet, and inbounds passes after made baskets; the two hash marks of the lower defensive box on NBA floors; the lines 28 feet from each end line marking the coaching box and bench; the lines at half court where substitutes wait; the top of the key.

How it works

A basketball court diagram labeled with 14 parts, drawn to scale from the NBA's 94 by 50 feet. Start with the 9 main parts, then the lines and marks, then everything under the basket.

Read the full guide

The lines that score

A basket from beyond the three-point line counts three, from inside it two, and a foul shot from the free-throw line one. The NBA line is 23.75 feet from the basket and 22 feet in the corners.

Different rule books, different courts

This drawing uses NBA sizes. A FIBA court is 28 by 15 metres, the NCAA key is 12 feet wide, and most US high schools put the three-point line at 19.75 feet. Many older high school gyms are only 84 or 74 feet long.

  • The no-charge arc and the lower defensive box work together: the box decides when a defender inside the arc can still draw a charge.
