Dartboard measurements: height, distance and setup

Hang the board so the centre of the bullseye is exactly 1.73 m above the floor you throw from.

The 20 goes at the top. Turn the board so the narrow black-and-white segment of the 20 sits vertically above the centre.

Place the throwing line (oche) 2.37 m horizontally in front of the board face — measured from the front of the board, not from the wall.

Check with the diagonal: from the bullseye to the throwing line it is 2.93 m. If that matches, height and distance agree with each other.

Light the board so the darts cast no shadow on it — from the side or with a ring light, never from behind over your shoulder.
