The lane's long and narrow shape limits straight-line ball paths to angles that are smaller than optimum angles for achieving strikes accordingly, bowlers impart side rotation to hook (curve) the ball into the pins to increase the likelihood of striking. The 41.5-inch-wide (105 cm), 60-foot-long (18 m) lane is bordered along its length by gutters ( channels) that collect errant balls. Ball contacts the 1, 3, 5, and 9 pins (sequentially tinted red) to achieve a strike.Īn approximately 15 feet (5 m) long approach area used by the bowler to impart speed and apply rotation to the ball ends in a foul line.
