Darts is a popular pastime and a sport enjoyed indoors. If you have your own dartboard and wish to set it up in your home you would be wise to mount it to a backboard, which protects walls from stray throws. The standard height to hang a dart board is 5 foot 8 inches from floor to centre of bull's-eye. A standard plywood sheet is 8-by-5 feet, making it a near perfect size for a dart backboard.
Set the plywood sheet down on the ground. Measure a distance of 5 feet 8 inches from the bottom of the sheet. Mark the measurement.
Drop a chalk line at the mark, across the width of the plywood. Measure to the exact centre of the line and mark it. With the plywood sheet being 5 feet wide, the centre mark is 30 inches from either side.
Apply earthquake tape or putty --- a highly sticky and stout adhesive that is used to secure heavy paintings and items to shelves in earthquake regions, and which is found in most home hardware stores --- to the back of the dart board. Place a piece in the centre of the dart board and four to five pieces around the edge of the backside of the dart board.
Mount the dart board to the plywood so the bull's-eye lines up with the centre of the marked chalk line. Press the dart board on the plywood to set the putty or tape.
Turn the plywood over and place putty or tape in each corner and at least three other pieces between each corner, along the edge of the plywood. Place two or three pieces in the centre of the plywood.
Press the backboard plywood to a wall or surface where the dart games will be played. Measure and mark a distance of 7 feet 9 1/4 inches from the base of the backboard straight out from the dart board. This is the oche line, which is where you stand to throw the darts.
