How to mark a 3x3 basketball court
- Fix one end line. Stretch a string line 15 m long between two pins.
- Square the corner with 3-4-5. 3 m along the end line, 4 m out along the side; when the gap reads exactly 5 m, the corner is square. Run the side line out to 11 m.
- Check both diagonals. Each must read 18.601 m. If they differ, move the corners before marking any line.
- Mark the inner lines.
- Three-point line: arc of 6.75 m radius from the point under the ring.
- Free-throw line: far edge 5.80 m from the end line.
- Restricted area: 4.90 m wide, from the end line to the free-throw line.
- No-charge semicircle: 1.25 m radius to its inside edge.
- Mark to the right edge. Measured to the inside of the boundary line. The line sits outside the court, so a ball on the line is out. Mask both sides of every line with tape before painting.
