To make a accurate darts oche, use a laser to project the line onto the floor. Laser oche emits a laser beam with adjustable line distance to mark your throw line.

Generally, the oche width is 2 feet for floor events and 5 feet for stage events. It can be easily adjusted using a laser oche.

The term 'oche' in darts is believed to originate from the Old English word 'hocken', which means 'a line from which to throw.' It refers to the line players must stand behind when throwing their darts.

The distance from the dartboard to the oche is 7 feet 9.25 inches (2.37 meters) for steel-tip darts and 8 feet (2.44 meters) for soft-tip darts.
