 Bowling Rules

The Lane and Equipment

The playing surface om a bowling lane is 60 feet long from the foul line to the head or first pin that is 42 inches wide. On both sides of the lane are gutters, if the bowling ball goes off the edge of the lane, it will drop into the gutter and be carried past the pins. The approach is an area of 15 feet long, ending at the foul line. The bowler, when making the approach, must not step over the foul line; 60 feet beyond it is the headpin. The pins are arranged in four rows, with one pin in the first row, two in the second, three in the third, and four in the fourth. They are numbered 1-10; the pins themselves don’t carry specific numbers, but the spots on which they are placed do.

The regulation pin is made of hard maple; it is 15 inches high and has a diameter of 2 ¼ inches at the base and a circumference of 15 inches at its widest point. Weight must be between 3 pounds, 6 ounces and 3 pounds, 10 ounces. The regulation ball is of solid composition, has a circumference of no more than 27 inches, and weighs 10 to 16 pounds. A bowling ball may have two or three finger holes; most bowlers use the three-holed ball, inserting the two middle fingers and the thumb into the holes.

Bowling in ordinary or street shoes isn’t permitted, because it can damage the lanes. The peculiarities of the sport demand an unmatched pair of shoes. The right-handed bowler wears a left shoe with a relatively slippery sole, usually of hard leather or vinyl, and a right shoe with a rubber sole that will help “brake.”

Progress of Play

A bowling game is made up of 10 frames. Each frame represents one turn for the bowler, and in each turn the player is allowed to roll the ball twice. If the player knocks down all the pins with the first roll, that is called a strike; if not, a second roll at the pins still standing is attempted. If all the pins are knocked down with two balls, it is a spare; if any pins are left standing, it is an “open frame.”

If a bowler commits a foul, by stepping over or touching the foul line during delivery, it counts as a shot, and any pins knocked down are re-spotted without counting. If pins are knocked down by a ball that has entered the gutter, or by a ball bouncing off the rear cushion, they do not count, and are re-spotted.


In an open frame, a bowler simply gets credit for the number of pins knocked down. In the case of a spare, a slash mark is recorded in a small square in the upper right-hand corner of that frame on the score sheet, and no score is entered until the first ball of the next frame is rolled.

Then credit is given for 10 plus pins to the number of pins knocked down with that next ball. For example, a player rolls a spare in the first frame; with the first ball of the second frame, the player knocks down seven pins. The first frame, then, gets 17 points. If two of the remaining three pins get knocked down, 9 pins are added, for a total of 26 in the second frame.

If a bowler gets a strike, it is recorded with an X in the small square, the score being 10 plus the total number of pins knocked down in the next two rolls. Thus, the bowler who rolls three strikes in a row in the first three frames gets credit for 30 points in the first frame.

Bowling’s perfect score, a 300 game, represents 12 strikes in a row–a total of 120 pins knocked down, this is not easy. Why 12 strikes, instead of 10? Because, if a bowler gets a strike in the last frame, the score for that frame can’t be recorded before rolling twice more. Similarly, if a bowler rolls a spare in the last frame, one more roll is required before the final score can be tallied.
