Bowling Average Calculator
Average three bowling games and get your series total and high game in one shot.
How it works
average = (game 1 + game 2 + game 3) ÷ 3
A standard league night is a three-game series, and your average is simply the series total divided by three. League books track this over the whole season — your official average is total pins over total games, not an average of nightly averages. Scores run 0 to 300, where 300 is twelve consecutive strikes.
Worked example
Games of 156, 178 and 142 total a 476 series; 476 ÷ 3 = 158.7 average, with a high game of 178.
Frequently asked questions
What is a good bowling average?
Casual bowlers often sit 80–120; committed league bowlers 150–180; 200+ marks a genuinely skilled amateur. Professional averages in competition run around 220–230.
How does my average set my league handicap?
A common formula is 90% of the gap to a basis score: with a 220 basis, a 158 average gets (220 − 158) × 0.9 ≈ 55 pins per game added. Your league sheet states its own basis and percentage.
What series should I aim for?
A 500 series (167 average) is a solid league milestone, 600 is strong, and 700 is excellent. Consistency across all three games matters more than one big game.
