How long is a basketball court?
An NBA, WNBA or college basketball court is 94 feet long (about 31.3 yards or 28.65 m) and 50 feet wide (16.7 yards). A high school court is 84 feet long (28 yards) and 50 feet wide. That makes a full NBA or college court 4,700 square feet and a high school court 4,200 square feet.
Running the outside lines of an NBA or college court covers 288 feet, so about 18⅓ laps make a mile. On a high school court (268 ft around) it takes about 19⅔ laps.
How wide is a basketball court?
NBA, WNBA, college and high school courts are all 50 feet wide (about 16.7 yards). A FIBA court is 15 m wide, about 49.2 feet. Only the length changes between US levels.
Basketball court size in feet, by level
| Level | Length | Width | 3-point line (top) | 3-point (corners) | Lane width |
|---|---|---|---|---|---|
| NBA | 94 ft | 50 ft | 23 ft 9 in | 22 ft | 16 ft |
| WNBA | 94 ft | 50 ft | 22 ft 1.75 in | 21 ft 8 in | 16 ft |
| NCAA (men's and women's) | 94 ft | 50 ft | 22 ft 1.75 in | 21 ft 8 in | 12 ft |
| High school (NFHS) | 84 ft | 50 ft | 19 ft 9 in | 19 ft 9 in | 12 ft |
| FIBA / Olympics | 28 m (91.9 ft) | 15 m (49.2 ft) | 6.75 m (22 ft 1.75 in) | 6.6 m (21 ft 8 in) | 4.9 m (16 ft) |
The NBA, WNBA, and NCAA all play on the same 94 × 50 ft floor. High school courts are 10 feet shorter at 84 ft, and many middle school gyms are smaller still. International (FIBA) courts are slightly smaller: 28 × 15 m, about 91.9 × 49.2 ft. See the full high school basketball court dimensions.
NBA court dimensions
An NBA court is 94 × 50 ft, with a 16 ft wide lane and a 3-point line 23 ft 9 in from the basket, or 22 ft in the corners. The restricted-area arc is 4 ft from the center of the basket.
Basketball court lines and layout
A basketball court layout uses the same set of lines at every level, though some of the distances change:
- Sidelines and baselines: the outer boundary. Baselines are also called end lines.
- Half-court line: divides the court in two, with the center circle on it.
- Lane (the key): the painted rectangle from the baseline to the free-throw line.
- Free-throw line: the top of the lane, 15 ft from the backboard.
- Free-throw circle: the 6 ft radius circle on the free-throw line.
- 3-point line: the arc around the basket, at a distance that depends on the level.
- Restricted-area arc: the 4 ft arc under the basket on NBA courts.
Markings that are the same everywhere
| Marking | Measurement |
|---|---|
| Rim height | 10 ft (3.05 m) above the floor, at every level from high school to the NBA |
| Free-throw line | 15 ft from the face of the backboard (19 ft from the baseline) |
| Backboard | 6 ft wide × 3.5 ft tall (72 × 42 in), hung 4 ft inside the baseline |
| Rim diameter | 18 in (inside) |
| Center circle | 12 ft diameter (6 ft radius) |
| Restricted-area arc (NBA) | 4 ft radius from the center of the basket |
Half court basketball dimensions
| Court | Size |
|---|---|
| NBA / NCAA half court | 47 × 50 ft |
| High school half court | 42 × 50 ft |
| Common backyard half court | 30 × 30 ft to 35 × 30 ft (key plus 3-point area is not regulation at this size) |
A regulation half court is simply half a full court: 47 × 50 ft for the NBA or college, 42 × 50 ft for high school. Driveway and backyard courts are usually much smaller; at 30 × 30 ft you get a full-size key but only part of a high school 3-point arc. See the half court size guide for the space each 3-point line needs.
What is the key in basketball?
The key is another name for the lane. The painted lane runs from the baseline to the free-throw line, 19 ft long. It is 16 ft wide in the NBA, WNBA, and FIBA, and 12 ft wide in college and high school. The free-throw circle on top of it has a 6 ft radius.

How to draw a basketball court
A scale of 1 inch to 10 feet fits a full court on a sheet of paper. Using high school measurements:
- Draw a rectangle 8.4 in long and 5 in wide for the court (84 × 50 ft).
- Draw the half-court line across the middle, with a circle of 0.6 in radius at its center.
- At each end, draw the lane: 1.9 in long and 1.2 in wide, centered on the baseline.
- Add a circle of 0.6 in radius centered on the end of each lane, for the free-throw circle.
- Mark the basket 0.525 in from the center of each baseline, then draw an arc of 1.975 in radius around it for the 3-point line.
- Run straight lines from each end of that arc back to the baseline.
