For some people, putting a screw in a wall at about eye level, hanging a dartboard on it and throwing darts from some random distance away from the board is good enough when it comes to setting up a dartboard. However, to properly mount a dartboard on a wall, set it up correctly and play according to the proper rules, you will need to take a little time and do a little measuring.
Check to make sure the mounting bracket attached to the back of the dartboard is centred. Typically the bracket is even with the bull's-eye but if it's not, use the tape measure to measure from the bracket to the centre of the board so that you can include this in your next measurement.
Measure from the floor to a height of 5 feet, 8 inches and mark the wall with a pencil. This is the height that the bull's-eye should be at. If necessary, add the distance of the difference between the bull's-eye and the mounting bracket to compensate, and mark the wall at that height.
Install a drywall anchor at the spot you have marked. Be sure the anchor is the correct size for the screw you will be using to hang the board. If you are putting the screw directly into a stud, the anchor is not needed.
Use the screwdriver to insert the screw in the anchor, leaving enough of the screw and head exposed to hang the board so that it sits reasonably flush to the wall. Hang the dartboard on the screw.
Use the tape measure to measure out from the face of the dartboard to a distance of 7 feet, 9 1/4 inches. This is the distance to the toe line, the spot you must stand behind to throw the darts. If you are measuring from the wall, don't forget to add the thickness of the dartboard. Place a piece of masking tape on the floor to mark the toe line.
Mount a piece of cork board or plywood on the wall that is larger than the dartboard, and then mount the dartboard on the cork board or plywood. This will help prevent darts from piercing holes in the wall if you miss the board.
