D-Zone Meaning in Billiards

The D-zone is a semi-circle marked on the head of a snooker or English billiards table. It is shaped like the letter ‘D’ and sits on the baulk-line. When starting a game or after a foul, the player must place the cue ball inside this specific area. It limits where you can start your shot, adding a layer of discipline to the game. For example, a player places the white ball on the far left edge of the D-zone to get a better angle on the break. This zone is a permanent landmark that dictates the flow of play in traditional cue sports. Understanding the D-zone is essential for anyone learning to play snooker.
