The 41.5-inch (105 cm) wide, 60-foot (18 m) lane.
Behind the foul line is an "approach" approximately 15 feet (5 m) long used to gain speed and leverage on the ball before delivering it. 60 feet (18 m) from the foul line, where the lane terminates, it is joined to a roughly 24-inch (61 cm), 41.5-inch (105 cm) wide surface of durable and impact-resistant material called the "pin deck" where each rack of pins is set.
This bowling lane is 60 feet (18.29 m) from the foul line to the head pin (1-pin). About 15 feet (4.57 m) from the foul line are a set of guide arrows. The lane is 41.5 inches (1.05 m) wide and normally consists of 39 wooden boards or a synthetic material. The bowling lane has two sets of approach dots; from the foul line back to the first set of approach dots is about 12 feet (3.66 m) and to the second set of approach dots is about 15 feet (4.57 m) (an additional 3 feet (1 m)). Although this figure varies, the lane is protected by about 18 ml of oil. The PBA events use about 30 ml of oil, and the PWBA events use 25 ml.
