The throwing distance or "oche" for darts is 7 feet 9 1/4 inches (or 237 centimeters) from the front of the dartboard to the toe line where the player stands. This is the standard distance used in most professional competitions as well as casual play. It's important to ensure that there is ample space around the dartboard to allow players to move and throw their darts comfortably, without any obstructions or hazards that could cause injury or damage.
