The standard length of a regular season in professional baseball is 162 games. This number has been the benchmark for the American League and the National League in Major League Baseball since 1961, providing a substantial sample size to determine the best teams.
The Historical Evolution of the Schedule
The journey to the 162-game schedule was not immediate. In the early days of the 20th century, teams played as few as 120 games. The number gradually increased, and the modern era of 154 games lasted for decades before expanding to 162 in the late 1950s and early 1960s.
Why 162 Games?
Mathematically, 162 games offer the perfect balance between a meaningful season and logistical feasibility. This length allows for a robust calculation of winning percentages and provides enough games to overcome the inherent randomness of any single contest, rewarding consistency over a long period.
Breaking Down the Numbers Each team faces every other team in its league 19 times, accounting for the bulk of the schedule.

While the official schedule is 162 games, the actual number of contests a team plays can fluctuate. Games postponed by rain or other acts of God are typically rescheduled, often as doubleheaders, ensuring the season concludes as close to the first week of October as possible.
Variations in the Minors and Beyond
Below the major league level, the number of games varies significantly. Triple-A affiliates might play 140 games, while lower levels of Minor League Baseball and international leagues like Nippon Professional Baseball operate on different schedules, usually shorter than the MLB standard.
