Professional Boxing - Length of Bouts

Length of Bouts

Professional bouts are limited to a maximum of twelve rounds, most are fought over four, six, eight or ten rounds depending upon the experience of the boxers. Through the early twentieth century, it was common for fights to have unlimited rounds, ending only when one fighter quit or the fight was stopped by police. In the 1910s and 1920s, a fifteen-round limit gradually became the norm, benefiting high-energy fighters like Jack Dempsey.

For decades, from the 1920s to the 1980s, world championship matches in professional boxing were scheduled for fifteen rounds, but that changed after a November 13, 1982 WBA Lightweight title bout ended with the death of boxer Duk Koo Kim in a fight against Ray Mancini in the 14th round of a nationally televised championship fight on CBS. Exactly three months after the fatal fight, the WBC reduced the number of their championship fights to 12 rounds. The WBA even stripped a fighter of his championship in 1983 because the fight had been a 15-round bout, shortly after the rule was changed to 12 rounds. By 1988, to the displeasure of some boxing purists, all fights had been reduced to a maximum of 12 rounds only, partially for safety, and partially for television, as a 12-round bout could be broadcast within an hour, while a 15-round bout could require up to 90 minutes to broadcast.
