How to mark a throwball court
- Fix one end line. Stretch a string line 12.20 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 18.30 m.
- Check both diagonals. Each must read 21.994 m. If they differ, move the corners before marking any line.
- Mark the inner lines.
- Box line: 1 m from the centre of the court.
- Mark to the right edge. Measured to the outside of the boundary line. The line is part of the court, so a ball on the line is in. Mask both sides of every line with tape before painting.
