There are four simple tips on how to hang a dartboard.
Firstly, choose your dart area carefully. Try to avoid hanging a dart board in a high traffic area, like near a bathroom, near anything breakable or on a hard concrete floor. If you have to use a hard floor, the best solution is to purchase a dart mat.
Secondly, hang the dart board. The board needs to hang exactly 5 feet 8 inches from the floor to the center of the bull’s-eye. Most quality dartboards have a screw in the center. However, if you have a board that hangs from the top, you will have to measure the distance to the center of the bull’s-eye and add that to the height. If a back board is used to protect the wall around the board, this will also have to be centered around the board.
Thirdly, create the throwing line. A darts throw line should be roughly three feet wide. You can use tape, a store bought throw-line sticker, a piece of wood or a metal molding that is screwed in the floor. For a standard, steel-tip set up, the line should be placed exactly 7 feet 9 and 1/4 inches from the face of the board. For soft-tipped darts, the line should be 8 feet from the face of the board. To measure from the face of the board, hold a piece of string with a dart tied to one end from the front of the board to the floor. Start from the bottom of the hanging dart and measure out 7’ 91/4”. To be notice that you should make sure the throw line is straight and centered with the dart board.
Then, make sure you have good lighting. It goes without saying that it's very important to have good lighting on your dartboard. The best set up is two lamps mounted on the ceiling on the right and left about four feet from the board. You can use one lamp, however you risk creating some shadows with only one light source. You really want to make sure the person at the line doesn't have to move from the line to better see the darts on the board. Clip-on metal lamps are a reliable and cheap option. Just use a couple 75 watt bulbs and clip them to the ceiling for a brightly lit dartboard.
